Ask A Genius 1310: Information, Physics, and Metaphysics, or Information and Physics with 'Metaphysics'

Scott Douglas Jacobsen: Why do objects and operators in the universe break down into something unique—something that holds a stable property in the universe? You look at one electron, and it’s the same as every other electron in the universe. You look at a photon, and it’s the same deal. So why? Why do fundamental particles remain indistinguishable while larger-scale objects mostly do as…

D-17 NEET; 45/100 days of Productivity

18th April, 2025

Academic:

(last few days)

I did around 23 questions on significant digits. I needed to revise this part though it was pretty simple.

I noted down the common topics of PYQs of biotechnology. This is one chapter that often confuses me. But noting down the topics is definitely giving me an entry into the chapter.

I wrote down the common topics for Anatomy of Flowering plants too, but that was last night.

Started reading notes of Biotechnology. It's like I'm reading it for the first time.

April 18th

5:02 pm

- I revised lec1 nuclie notes. Braindump:

"BE/A vs A graph will first increase then decrease. Types of fundamental particles: quark, neutrino, anti neutrino, electron. Up quark = +2/3. Down quark = -1/3. Proton = 2 up quark + 1 down quark. Neutron = 2 down quark + 1 up quark. Nucleons: protons and neutrons. V & A ⇒ 4/3π r^3 & A ⇒ r & a^1/3. R = R°A^1/3. E = mc^2. Neutron mass: 1.67 x 10^-27 kg = 1.0087 amu. Proton mass: 1.67 x 10^-27 kg = 1.0073 amu. 1 amu= 931.5 MeV/c^2 =1.66 x 10^-27 kg. Mass defect = mass of nucleons - mass of nucleus. BE = ∆m.c^2. BE/A & stability. Density does not depend on A (mass number). (& = Directly proportional)"

--------------------

5:33pm

- I did 2 questions of Target Publications mock test 1.

"The first question was about % error - U&D. I did a mistake of just calculating error. The 2nd question was about finding the focal length and the power of a lens. The main formulas used:"

12:31 am

- I spend a few hours doing nothing. Probably because I was scared.

- In the last half hour, I studied about:

"Conservation of energy and what kind of energy is released."

I'm probably going to just study a little more but I wanted to share this since I haven't shared in a while.

SpaceTime 20250407 Series 28 Episode 42

Another clue into the antimatter universe

Physicists have discovered a fundamental difference in the decay behaviours of a matter particle and its antimatter counterpart. The discrepancy could bring scientists a step closer to understanding how everything in the universe came to be.

A new technique to detect dark matter

Scientists have developed an innovative new approach to uncover the secrets of dark matter using atomic clocks and cavity-stabilized lasers. Dark matter is a mysterious invisible substance which makes up some 80 percent of all matter in the universe – yet scientists have no idea what it is.

What caused the Spectrum rocket failure?

Investigators working to determine the cause of last week’s Spectrum rocket launch failure are looking at the guidance control system. Spectrum was launched from the Andøya Spaceport on Norway’s northern west coast on what should have been the first ever orbital rocket launch from mainland Europe.

SpaceTime -- A brief history

SpaceTime is Australia’s most popular and respected astronomy and space science news program – averaging over two million downloads every year. We’re also number five in the United States.  The show reports on the latest stories and discoveries making news in astronomy, space flight, and science.  SpaceTime features weekly interviews with leading Australian scientists about their research.  The show began life in 1995 as ‘StarStuff’ on the Australian Broadcasting Corporation’s (ABC) NewsRadio network.  Award winning investigative reporter Stuart Gary created the program during more than fifteen years as NewsRadio’s evening anchor and Science Editor.  Gary’s always loved science. He studied astronomy at university and was invited to undertake a PHD in astrophysics, but instead focused on his career in journalism and radio broadcasting. Gary’s radio career stretches back some 34 years including 26 at the ABC. He worked as an announcer and music DJ in commercial radio, before becoming a journalist and eventually joining ABC News and Current Affairs. He was part of the team that set up ABC NewsRadio and became one of its first on air presenters. When asked to put his science background to use, Gary developed StarStuff which he wrote, produced and hosted, consistently achieving 9 per cent of the national Australian radio audience based on the ABC’s Nielsen ratings survey figures for the five major Australian metro markets: Sydney, Melbourne, Brisbane, Adelaide, and Perth. That compares to the ABC’s overall radio listenership of just 5.6 per cent. The StarStuff podcast was published on line by ABC Science -- achieving over 1.3 million downloads annually.  However, after some 20 years, the show finally wrapped up in December 2015 following ABC funding cuts, and a redirection of available finances to increase sports and horse racing coverage.  Rather than continue with the ABC, Gary resigned so that he could keep the show going independently.  StarStuff was rebranded as “SpaceTime”, with the first episode being broadcast in February 2016.  Over the years, SpaceTime has grown, more than doubling its former ABC audience numbers and expanding to include new segments such as the Science Report -- which provides a wrap of general science news, weekly skeptical science features, special reports looking at the latest computer and technology news, and Skywatch – which provides a monthly guide to the night skies. The show is published three times weekly (every Monday, Wednesday and Friday) and available from the United States National Science Foundation on Science Zone Radio, and through both i-heart Radio and Tune-In Radio.

evil women weird sex why

OHKAY!! let us discuss erygora. this will take some time as there are literally billions of years of history and be very confusing as there are literally billions of years of history. plus I am a chronic yapper.

meta info:

this is my main oc collection (the poera mythos) which stems from my immersive daydreaming (started aged 7) and exists purely as a convoluted vehicle for me to torture fictional women in my mind. there are a lot of them but I think about the weird sex evil gods a lot. (side note they are not women they are gods who just. look like women because I made Erykwana when I was like 10 and Gora when I was 13. insanity. we will call them majaerajji and use she/her)

background:

there is. a lot of lore since I've been living part-time in this universe (triverse. there are three) for 9 years (scary!!). but I will (try) give only necessary info. also pls don't worry about how to pronounce any of it.

there are three universes. two are for mortals, one is much smaller and for the Gods. these universes were created by the Feqa (literally translated as 'Creator') who you don't need to worry about. The Feqa also created two kinds of Gods to 'take care' of the triverse. these are the lumadiimi (gods of concepts) who you don't need to worry about and the majaerajji (gods of 'elements' as in like the arcane elements but I really stretch the definition of that by the end) who you do need to worry about.

there are 4 different majaerajji for each element (so. eg 4 majaerajji for water), and these majaerajji are sorted into four clans, with one majaerajji for each element in each. so every clan has one majaerajji of water, one majaerajji of air etc etc. are you keeping up I promise this is relevant.

you need only worry about two of these clans: the mraninia-csora (gilded clan) and vryciila-csora (burnished clan). the mraninia were chosen by the Feqa to 'rule' over the triverse and be regarded as above the other majaerajji (the Feqa impose a strict hierarchy of beings. remember this because it will be important later). since all majaerajji are referred to as 'queens' eg. gilded queen of fire, the ruling clan are referred to as 'high queens' eg. high queen of earth. notice I say 'ruling clan' not specifically the mraninia-csora. this is foreshadowing.

one of the majaerajji elements is 'matter'. this is essentially control over particles ranging in size from quarks/leptons/other fundamental particles etc to large monomers (not polymers!!). majaerajji of matter can do cool stuff like break/form atomic bonds, do nuclear fusion/fission on command etc (this is where. head exploding comes from). anyway.

actually talking about the weird sex evil gods:

the majaerajji of matter in the mraninia-csora is Erykwana. the majaerajji of matter in the vryciila-csora is Gora (yes I know shut up).

I will now talk at length about their characters because goddamnit I didn't do all that development for nothing.

Erykwana:

most of Erykwana's beliefs etc come from her very very strong belief in the heirarchy set out by the Feqa. the only thing you need to know about this is that it places majaerajji above humans. boy does she internalise this. this bitch does not give a single fuck about mortals and she never has. this means she feels zero shame about anything she's done. speaking of which:

most of Erykwana's actions etc (in the Stability Epoch anyway. oop what's that) come from her being a massive sadist and weirdo who likes to torture people.

in the Stability Epoch (beginning of time - about 400 years ago) Erykwana would go down to mortal worlds, eat chunks off people (majaerajji do not need to eat in fact they do not digest things. everything they eat they permanently destroy. she enjoyed the feeling of perma-destroying stuff because she was an immortal god with not enough enrichment in her unchanging existence. fun fact.), blow up their heads and kidnap them back to the Gods' universe. this is where Gora comes (haha) into the picture:

Gora:

ignore the name🤗🤗 thank you. anyway I think it's funny.

Gora was also an artist in a similar way to Erykwana: while Erykwana's art was broken bodies/screams, Gora's art was broken minds. she liked to see people break and took it as a challenge to break down the strongest most resilient people.

Gora and Erykwana spent almost every second of every day together and they don't even need to sleep so you know it was every day bro!! wow. lots of people died during this time (like. hundreds of billions. it's crayzy)

but why would Gora stick around Erykwana when they had different art styles. haha.

I'm glad you asked!! there are two reasons for this:

all the other majaerajji are actually not awful (debatable. in fact probably untrue). anyway so they did not want to be friends with either of them and really really hated/excluded them both. Erykwana and Gora were viewed as one entity with no differences between them (untrue!!) and this kind of. pushed them further together because (and this is important) they were the only people who could ever fully understand the other!!

this is very important also!! Gora wanted to be Erykwana. the desire consumed her. she resented Erykwana for existing because if Erykwana was Erykwana.. then Gora wasn't. if that makes sense. Gora was absolutely obsessed with Erykwana and spent all her time trying to emulate her in many ways

Klla (the beginning of the end):

Erykwana was looking for a new shiny enrichment torture method which would make people really really scream. she pitched the idea to Gora and they started to create Klla.

Klla was a spell which was embedded in a knife. it would cause indescribable pain (like. literally the worst ever possible I can't convey to you.. anyway this 1/2 of how I torture the fictional women) to the victim without leaving a physical mark (the knife just. passes through. this is what appeals to Gora). anyway you don't need to know much except that a) the spell is in two parts, the first part allows the knife to be used as Klla and the second part 'activates' it so the next time the knife goes into someone it will begin the Klla process in them😈 so the knife functions as a normal knife between the first and second parts of the spell. this is irrelevant beyond when Erykwana and Gora are just regular stabbing each other. b) it's contagious heehee so if you touch someone who's just been stabbed then the process begins in you too😈 anyway none of this is particularly important but it's useful context if you. read my stuff

Klla was the ACTUAL last straw for the majaerajji who had just been chilling up until now. most of them thought it was 100% Erykwana (it was like. 90% but still).

it especially pissed off a certain member of the vryciila-csora (remember? the family Gora is in? I'm crying there's so much of this) who will not be named, who then went to her sister (also unnamed) and they decided to overthrow the entire mraninia-csora (remember?? the ruling family that Erykwana is in???)

I won't go into detail about the LVD/etc etc because it's irrelevant but you do need to know that they approached Gora in the early stages of their plotting and she was jumping for joy!! at the possibility of usurping Erykwana because that was one step closer to fully becoming her..

ok you don't need to know anything about the last violet dance/Big War beyond that Erykwana used the Klla knife on Gora first. anyway fun fact.

Klle (a different thing!!):

during the Big War (name pending) Erykwana emotionally manipulated her pathetic spineless wet wipe sister into helping her make a new weapon to use in the war.

this new weapon was Klle, which is basically the mental equivalent of Klla. (no details that's far too deep in my own brain)

I mention Klle even though they never use it on each other because it's the obvious second part to Klla right? like Erykwana = Klla, Gora = Klle. Klle is what they would've eventually made together if the Big War had never happened. and Erykwana (subconsciously-ish) made it for her. anyway. GOD I miss them.

what happened next: the ACTUALLY ACTUALLY relevant bit

sorry about all the shit you've had to read that didn't really matter. um.

well, Erykwana/her family lost the war and the vryciila-csora became High Queens. so Gora is now High Queen of matter. there's a fuck tonne of other stuff this caused but there's no need to worry about that

Gora being High Queen continues to deeply piss of Erykwana since it is so flagrantly in opposition to the natural order set out by the Feqa, which intended for Erykwana to be High Queen.

and so Erykwana has become genuinely obsessed with the idea of killing Gora forever (difficult since Gora is. an immortal god. but hey go off queen) side info: she's committed to the idea of remembering Gora's final scream forever and ever because she can't fathom existing without Gora by her side in. some capacity. Erykwana derives immense psychosexual pleasure from hurting Gora. this is why there's all the torture sex with the knife they made together... the bridge between them.. the child of divorce..

Gora is of course still obsessed with becoming Erykwana etc etc. and also gets a definitely psychosexual pleasure from doing to Erykwana everything that Erykwana has done to her and doing to herself everything she's done to Erykwana (including torture because. she's number 1 committed to the bit) as a form of symmetry. you know. that's why she's returning all the knife torture sex.

Pythagoras realized, said, coined the reality of perspective when he expressingly realised and then revealed “Physical matter is music solidified.” This poetic insight, attributed to the ancient philosopher-mathematician Pythagoras, unveils a profound bridge between the tangible and the ineffable, the material and the metaphysical. At its core, this phrase invites us to perceive the universe not as a mechanistic expanse of inert substances, but as a living symphony, where the fundamental principles of existence are woven together by vibrations, harmonies, and numerical precision.

1. The Vibratory Essence of All Things

At the heart of this concept is the primacy of vibration, the universal pulse that underlies both sound and matter. Music, at its essence, is organized vibration—a cascade of frequencies arranged into harmony and rhythm. Similarly, modern physics reveals that physical matter, when examined at its most fundamental level, consists of vibrational energy. Atoms, molecules, and particles are not static entities but oscillating waveforms, stabilized into perceivable forms through resonance. Matter, then, is a dense choreography of standing waves—a slower, more grounded echo of the symphonic frequencies that create sound.

2. The Marriage of the Immaterial and the Material

Music dwells in the intangible realm of time, its presence ephemeral yet transformative. Matter, conversely, occupies space, seemingly enduring and immutable. Yet Pythagoras’ insight reminds us that these two realities are not disparate. They are emanations of the same underlying principle: vibration. Physical matter is, in essence, music made visible, its melodies frozen into form, its rhythms sculpted into permanence. This poetic unity blurs the line between the physical and the abstract, suggesting that the material world is not separate from the spiritual or conceptual but is its tangible expression.

3. The Universe as a Cosmic Orchestra

To Pythagoras, the cosmos was not a chaotic expanse but a masterpiece of mathematical order, a grand orchestra playing the “music of the spheres.” He envisioned celestial bodies as instruments of the divine, their movements governed by precise numerical relationships, each contributing to the harmony of existence. If physical matter is indeed “music solidified,” then every star, every stone, and every particle participates in this cosmic symphony, vibrating with the essence of creation. Existence becomes a multidimensional composition, where matter represents a single octave in an infinite scale of reality.

4. A Resonance with Modern Science

Remarkably, Pythagoras’ ancient intuition aligns with the revelations of modern physics. Quantum mechanics reveals a universe of energy fields, where particles behave not as solid entities but as probabilities, governed by wave-like motion. String theory, too, echoes the notion that the fabric of reality is woven from vibrational strings, resonating at different frequencies to produce the diversity of matter and forces. Thus, the phrase “Physical matter is music solidified” is no mere metaphor—it resonates with the cutting-edge understanding of the universe as a vibratory phenomenon.

5. Matter as a Portal to the Divine

This perspective transforms our perception of the physical world. What appears inert and lifeless—stone, wood, metal—is, in truth, a living expression of universal harmony. To study matter is to hear the echoes of a cosmic symphony, to glimpse the mathematical and musical architecture of the divine. It suggests that music is not merely an art form but a key to understanding the deeper truths of existence, a way to attune ourselves to the resonances that shape and sustain reality.

In this luminous vision, the universe becomes a cathedral of sound and form, its foundations composed of vibratory energy, its structures harmonized through the mathematics of creation. The material world, rather than being a solid, static construct, is a resonant, pulsing reflection of higher cosmic principles. “Physical matter is music solidified” invites us to see beyond appearances, to feel the pulse of the cosmos in every atom, and to hear, in the silence of form, the song of existence itself.

MIT researchers discover “neutronic molecules”

New Post has been published on https://thedigitalinsider.com/mit-researchers-discover-neutronic-molecules/

MIT researchers discover “neutronic molecules”

Neutrons are subatomic particles that have no electric charge, unlike protons and electrons. That means that while the electromagnetic force is responsible for most of the interactions between radiation and materials, neutrons are essentially immune to that force.

Instead, neutrons are held together inside an atom’s nucleus solely by something called the strong force, one of the four fundamental forces of nature. As its name implies, the force is indeed very strong, but only at very close range — it drops off so rapidly as to be negligible beyond 1/10,000 the size of an atom. But now, researchers at MIT have found that neutrons can actually be made to cling to particles called quantum dots, which are made up of tens of thousands of atomic nuclei, held there just by the strong force.

The new finding may lead to useful new tools for probing the basic properties of materials at the quantum level, including those arising from the strong force, as well as exploring new kinds of quantum information processing devices. The work is reported this week in the journal ACS Nano, in a paper by MIT graduate students Hao Tang and Guoqing Wang and MIT professors Ju Li and Paola Cappellaro of the Department of Nuclear Science and Engineering.

Neutrons are widely used to probe material properties using a method called neutron scattering, in which a beam of neutrons is focused on a sample, and the neutrons that bounce off the material’s atoms can be detected to reveal the material’s internal structure and dynamics.

But until this new work, nobody thought that these neutrons might actually stick to the materials they were probing. “The fact that [the neutrons] can be trapped by the materials, nobody seems to know about that,” says Li, who is also a professor of materials science and engineering. “We were surprised that this exists, and that nobody had talked about it before, among the experts we had checked with,” he says.

The reason this new finding is so surprising, Li explains, is because neutrons don’t interact with electromagnetic forces. Of the four fundamental forces, gravity and the weak force “are generally not important for materials,” he says. “Pretty much everything is electromagnetic interaction, but in this case, since the neutron doesn’t have a charge, the interaction here is through the strong interaction, and we know that is very short-range. It is effective at a range of 10 to the minus 15 power,” or one quadrillionth, of a meter.

“It’s very small, but it’s very intense,” he says of this force that holds the nuclei of atoms together. “But what’s interesting is we’ve got these many thousands of nuclei in this neutronic quantum dot, and that’s able to stabilize these bound states, which have much more diffuse wavefunctions at tens of nanometers [billionths of a meter].  These neutronic bound states in a quantum dot are actually quite akin to Thomson’s plum pudding model of an atom, after his discovery of the electron.”

It was so unexpected, Li calls it “a pretty crazy solution to a quantum mechanical problem.” The team calls the newly discovered state an artificial “neutronic molecule.”

These neutronic molecules are made from quantum dots, which are tiny crystalline particles, collections of atoms so small that their properties are governed more by the exact size and shape of the particles than by their composition. The discovery and controlled production of quantum dots were the subject of the 2023 Nobel Prize in Chemistry, awarded to MIT Professor Moungi Bawendi and two others.

“In conventional quantum dots, an electron is trapped by the electromagnetic potential created by a macroscopic number of atoms, thus its wavefunction extends to about 10 nanometers, much larger than a typical atomic radius,” says Cappellaro. “Similarly, in these nucleonic quantum dots, a single neutron can be trapped by a nanocrystal, with a size well beyond the range of the nuclear force, and display similar quantized energies.” While these energy jumps give quantum dots their colors, the neutronic quantum dots could be used for storing quantum information.

This work is based on theoretical calculations and computational simulations. “We did it analytically in two different ways, and eventually also verified it numerically,” Li says. Although the effect had never been described before, he says, in principle there’s no reason it couldn’t have been found much sooner: “Conceptually, people should have already thought about it,” he says, but as far as the team has been able to determine, nobody did.

Part of the difficulty in doing the computations is the very different scales involved: The binding energy of a neutron to the quantum dots they were attaching to is about one-trillionth that of previously known conditions where the neutron is bound to a small group of nuclei. For this work, the team used an analytical tool called Green’s function to demonstrate that the strong force was sufficient to capture neutrons with a quantum dot with a minimum radius of 13 nanometers.

Then, the researchers did detailed simulations of specific cases, such as the use of a lithium hydride nanocrystal, a material being studied as a possible storage medium for hydrogen. They showed that the binding energy of the neutrons to the nanocrystal is dependent on the exact dimensions and shape of the crystal, as well as the nuclear spin polarizations of the nuclei compared to that of the neutron. They also calculated similar effects for thin films and wires of the material as opposed to particles.

But Li says that actually creating such neutronic molecules in the lab, which among other things requires specialized equipment to maintain temperatures in the range of a few thousandths of a Kelvin above absolute zero, is something that other researchers with the appropriate expertise will have to undertake.

Li notes that “artificial atoms” made up of assemblages of atoms that share properties and can behave in many ways like a single atom have been used to probe many properties of real atoms. Similarly, he says, these artificial molecules provide “an interesting model system” that might be used to study “interesting quantum mechanical problems that one can think about,” such as whether these neutronic molecules will have a shell structure that mimics the electron shell structure of atoms.

“One possible application,” he says, “is maybe we can precisely control the neutron state. By changing the way the quantum dot oscillates, maybe we can shoot the neutron off in a particular direction.” Neutrons are powerful tools for such things as triggering both fission and fusion reactions, but so far it has been difficult to control individual neutrons. These new bound states could provide much greater degrees of control over individual neutrons, which could play a role in the development of new quantum information systems, he says.

“One idea is to use it to manipulate the neutron, and then the neutron will be able to affect other nuclear spins,” Li says. In that sense, he says, the neutronic molecule could serve as a mediator between the nuclear spins of separate nuclei — and this nuclear spin is a property that is already being used as a basic storage unit, or qubit, in developing quantum computer systems.

“The nuclear spin is like a stationary qubit, and the neutron is like a flying qubit,” he says. “That’s one potential application.” He adds that this is “quite different from electromagnetics-based quantum information processing, which is so far the dominant paradigm. So, regardless of whether it’s superconducting qubits or it’s trapped ions or nitrogen vacancy centers, most of these are based on electromagnetic interactions.” In this new system, instead, “we have neutrons and nuclear spin. We’re just starting to explore what we can do with it now.”

Another possible application, he says, is for a kind of imaging, using neutral activation analysis. “Neutron imaging complements X-ray imaging because neutrons are much more strongly interacting with light elements,” Li says. It can also be used for materials analysis, which can provide information not only about elemental composition but even about the different isotopes of those elements. “A lot of the chemical imaging and spectroscopy doesn’t tell us about the isotopes,” whereas the neutron-based method could do so, he says.

The research was supported by the U.S. Office of Naval Research.

With a quantum “squeeze,” clocks could keep even more precise time, MIT researchers propose

More stable clocks could measure quantum phenomena, including the presence of dark matter.

Jennifer Chu | MIT News

The practice of keeping time hinges on stable oscillations. In a grandfather clock, the length of a second is marked by a single swing of the pendulum. In a digital watch, the vibrations of a quartz crystal mark much smaller fractions of time. And in atomic clocks, the world’s state-of-the-art timekeepers, the oscillations of a laser beam stimulate atoms to vibrate at 9.2 billion times per second. These smallest, most stable divisions of time set the timing for today’s satellite communications, GPS systems, and financial markets.

A clock’s stability depends on the noise in its environment. A slight wind can throw a pendulum’s swing out of sync. And heat can disrupt the oscillations of atoms in an atomic clock. Eliminating such environmental effects can improve a clock’s precision. But only by so much.

A new MIT study finds that even if all noise from the outside world is eliminated, the stability of clocks, laser beams, and other oscillators would still be vulnerable to quantum mechanical effects. The precision of oscillators would ultimately be limited by quantum noise.

But in theory, there’s a way to push past this quantum limit. In their study, the researchers also show that by manipulating, or “squeezing,” the states that contribute to quantum noise, the stability of an oscillator could be improved, even past its quantum limit.

“What we’ve shown is, there’s actually a limit to how stable oscillators like lasers and clocks can be, that’s set not just by their environment, but by the fact that quantum mechanics forces them to shake around a little bit,” says Vivishek Sudhir, assistant professor of mechanical engineering at MIT. “Then, we’ve shown that there are ways you can even get around this quantum mechanical shaking. But you have to be more clever than just isolating the thing from its environment. You have to play with the quantum states themselves.”

The team is working on an experimental test of their theory. If they can demonstrate that they can manipulate the quantum states in an oscillating system, the researchers envision that clocks, lasers, and other oscillators could be tuned to super-quantum precision. These systems could then be used to track infinitesimally small differences in time, such as the fluctuations of a single qubit in a quantum computer or the presence of a dark matter particle flitting between detectors.

“We plan to demonstrate several instances of lasers with quantum-enhanced timekeeping ability over the next several years,” says Hudson Loughlin, a graduate student in MIT’s Department of Physics. “We hope that our recent theoretical developments and upcoming experiments will advance our fundamental ability to keep time accurately, and enable new revolutionary technologies.”

Loughlin and Sudhir detail their work in an open-access paper published in the journal Nature Communications.

🔬🌈 Exploring the Marvels of Fundamental Forces! 🔭💥

🔬🌈 Exploring the Marvels of Fundamental Forces! 🔭💥

-

🔥🌌 Hello, everyone! Today, we embark on an exhilarating journey into the world of fundamental forces that shape our universe. Let's dive deep into the fascinating forces that govern the cosmos: the Strong Force, the Weak Force, the Electromagnetic Force, and the Gravitational Force. 🌌🚀

-

🌟1️⃣ The Strong Force:

The Strong Force, also known as the Strong Nuclear Force, is one of the fundamental forces of nature. It binds atomic nuclei together, overcoming the electric repulsion between positively charged protons. 🧲🔒💪

-

💡 History:

In the early 20th century, physicists recognized that atoms were made up of smaller particles: protons and neutrons. However, they faced a conundrum since protons, all being positively charged, should repel each other and cause atomic nuclei to disintegrate. To explain this, in 1935, Hideki Yukawa proposed the theory of the Strong Force, which stated that particles called mesons acted as carriers of the force, mediating interactions between protons and neutrons. 🤝🔬

-

💥 Power:

The Strong Force is incredibly powerful, about 100 times stronger than the electromagnetic force. It acts over a very short range, only within the size of an atomic nucleus. This force is responsible for the stability of atomic nuclei, allowing stars to shine and elements to form. Without the Strong Force, our universe as we know it would not exist! 🌟🌍💫

-

💥🌈 #StrongForce #NuclearPower #NuclearPhysics

-

🌟2️⃣ The Weak Force:

The Weak Force, or Weak Nuclear Force, is another fundamental force of nature. It is responsible for certain forms of radioactive decay and plays a vital role in shaping the universe. ⚛️🌡️💔

-

💡 History:

In the mid-20th century, scientists discovered that certain subatomic particles decayed over time, emitting radiation. This led to the formulation of the theory of the Weak Force. In 1968, physicists Abdus Salam, Sheldon Glashow, and Steven Weinberg proposed the Electroweak Theory, unifying the Weak Force with the Electromagnetic Force. This breakthrough earned them the Nobel Prize in Physics in 1979. 🏆🌌🔭

-

💥 Power:

The Weak Force is the force responsible for processes such as beta decay, where a neutron transforms into a proton or vice versa, releasing an electron or a positron. It is weaker than both the Strong Force and the Electromagnetic Force, acting only over very short distances. The Weak Force played a significant role in the early moments of the universe, allowing particles to change and interact in unique ways. 🌠⏳⚡

-

💥🔬 #WeakForce #RadioactiveDecay #ParticlePhysics

-

🌟3️⃣ The Electromagnetic Force:

The Electromagnetic Force, one of the most familiar forces, governs the interactions between charged particles and the behavior of electric and magnetic fields. It plays a crucial role in everyday life. ⚡🧲🌍

What is a Quasicrystal? Approaches, And Future Implications

This article explains quasicrystals, their methods, and future implications.

What Creates Quasicrystals? Scientists Present First Quantum-Mechanical Model of Stability

A groundbreaking University of Michigan study that conducted the first quantum-mechanical simulations of quasicrystals found these strange materials to be fundamentally stable. This novel research overcomes classical  quantum mechanics  limits, solving quasicrystal understanding problems. The Nature Physics findings suggest that quasicrystals behave like stable crystals in their atomic arrangements despite their glass-like disorganised appearance.

What is a Quasicrystal

For decades, quasicrystals have puzzled scientists as a strange intermediate form between chaotic amorphous solids like glass and highly organised crystals. In contrast to ordinary crystals, quasicrystals have organised lattices but no infinitely repeating atomic patterns. After discovering a five-fold symmetry aluminium and manganese alloy in 1984, Israeli scientist Daniel Shechtman was the first to describe it.

Previously, this characteristic was supposed to prevent crystal repeating patterns. Shechtman won the 2011 Nobel Prise in Chemistry despite substantial criticism after other laboratories confirmed their existence and found them in billion-year-old meteorites. Quasicrystals lack indefinitely repeating patterns, which density functional theory (DFT), a classic quantum-mechanical technique, requires, hence their stability remains unsolved.

A New Simulation Method:

PhD student Woohyeon Baek and Dow Early Career Assistant Professor of Materials Science and Engineering Wenhao Sun developed a new modelling method to solve this problem. Instead of repeating, they “scoop out” tiny nanoparticles from a larger simulated quasicrystal block. Calculating the overall energy of these limited nanoparticles and extrapolating across increasing sizes can accurately predict the bulk quasicrystal's energy. Baek said, “The first step to understanding a material is knowing what makes it stable, but it has been hard to tell how quasicrystals were stabilised.”

Crystal-Stabilized Enthalpy:

The researchers found that two well-studied quasicrystal alloys of ytterbium-cadmium and scandium-zinc are “enthalpy-stabilized,” like crystals. Crystals are stable because their atomic configurations reduce chemical bond energy, unlike glass, which is “entropy-stabilized” by rapid cooling that freezes atoms into many chaotic arrangements.

Overcoming Computational Challenges:

Simulating the biggest nanoparticles was important to estimate energy accurately, which is difficult due to computing time scaling issues. Computing time may grow eightfold if nanoparticles were multiplied, even to hundreds. The GPU-accelerated method, developed with Professor Vikram Gavini, lowers processor-to-processor communication and speeds processing 100 times. This discovery simplified quasicrystal analysis and allowed simulation of complicated materials including glass, amorphous solids, and quantum computing-relevant crystal flaws.

Discovering Glass-Former Dynamic Similarities:

University of Michigan study showed that quasicrystals are structurally stable and resemble crystals, but a closer look at their dynamic properties revealed unexpected similarities to metallic glass-forming liquids. According to molecular dynamics simulations, glass-forming liquids and heated crystalline solids have quick beta and delayed alpha relaxation. Like quasicrystals and metallic glasses, they have a “kink” on Arrhenius plots for the temperature dependence of their diffusion coefficient and structural relaxation time.

Most crucially, dynamic heterogeneity in particle mobility fluctuations showed that the non-Gaussian parameter's peak value climbs with cooling, a behaviour more reminiscent of glass-forming liquids than hot crystals. Two types of atomic motion were found: isolated “phason flips” at low temperatures and frequent “string-like collective motions” at higher temperatures, which resembled glasses.

The “decoupling phenomenon,” the Stokes-Einstein link disintegration, best illustrates their glass-like dynamics. A fractional Stokes-Einstein relation with a decoupling exponent of 0.33 was found in which the temperature-normalized self-diffusion coefficient scales with structural relaxation time. Glass-forming liquids dissociate, whereas crystalline solids do not. This means metallic glass-forming devices are better at quasicrystal dynamics than crystals.

Future Impact:

A US Department of Energy-funded study sheds light on quasicrystals' fundamental properties. It supports the idea that quasicrystals are hybrid matter by connecting solid structure and motion. Phason flip movements and vibrational properties will be studied in three-dimensional quasicrystal models.

A Minimally Invasive Approach to Joint Care: What You Should Know About Arthroscopic Procedures

Joint discomfort—whether from injury, overuse, or wear and tear—can turn otherwise simple motions like bending, climbing stairs, or reaching overhead into daily challenges. Fortunately, modern joint therapy increasingly leans on minimally invasive techniques, helping people recover with less pain and downtime. Among these techniques is Arthroscopic surgery in Pune, a precise method that offers improved visualization and treatment of joint damage while sparing patients from large incisions. In this article, we’ll take a comprehensive look at this innovative procedure—starting with its fundamentals, moving through practical benefits and risks, and ending with essential post-care tips.

Understanding the Procedure

At its core, this technique involves the use of a slim instrument called an arthroscope—a miniature camera—introduced into the joint through tiny punctures. These portals allow the surgeon to visually inspect the joint in real time on a monitor. Additional tiny channels permit the use of specialized tools that can repair torn ligaments, remove debris, smooth rough surfaces, and more. Because the access points are so small, soft tissues like muscles, tendons, and skin suffer minimal trauma compared to traditional open surgery.

Typical Joint Targets

Though knees and shoulders are the most frequently treated joints, nearly any joint in the body can benefit from this method, including:

Knees – Commonly used for meniscal tears, torn cruciate ligaments, and cartilage defects.

Shoulders – Helps with rotator cuff repair, stabilizing loose shoulder joints, and treating arthritis.

Ankles – Ideal for removing bone spurs, treating ligament injuries, and addressing cartilage impairments.

Elbows – Used for stiff joints and removal of loose particles causing inflammation.

Hips and Wrists – Increasingly addressed through small-bore access to repair tears, remove inflamed tissue, or treat bone impingement.

Each joint has unique anatomy, but the guiding principle remains: less damage to surrounding structures equals faster recovery.

When It’s Recommended

Clinicians often suggest this type of joint intervention under circumstances such as:

Persistent pain, instability, or swelling that hasn’t responded to noninvasive care.

Imaging studies (like MRI, ultrasound, or CT scans) showing torn cartilage, ligament damage, or loose fragments.

Need for definitive diagnosis when non-surgical methods have been inconclusive.

Active individuals and athletes find this approach particularly appealing, as it minimizes time away from sports, work, or daily life.

Advantages Over Open Surgery

Some major benefits include:

Smaller Wounds – Typically only a few millimeters long, they heal quickly and leave minimal scarring.

Quicker Rehab – Most patients begin moving their joint within days, with full recovery often weeks sooner than with open procedures.

Lower Infection Risk – With less exposure of internal structures, the likelihood of infection drops significantly.

Same-Day Return – Many people return home within hours, avoiding lengthy hospital stays.

Clear Visual Access – Magnified views of the joint interior make it easier to target specific lesions precisely.

What to Expect – Before, During, and After

Before surgery, your surgeon will evaluate your needs through physical exams and imaging. You'll also get instructions on preoperative preparation, such as fasting, adjustments to medications, and arranging transport.

During the procedure, you'll typically be under regional or general anesthesia. Minor incisions are made for the camera and instruments. Most interventions—from removals to repairs—are performed under direct visualization. The process usually lasts between 30 minutes and two hours, depending on the complexity.

After surgery, you’ll be observed briefly before heading home. Expect some swelling, mild discomfort, and protective dressing. Compression, ice, and medications help manage symptoms, and custom rehab plans begin almost immediately.

Recovery and Rehabilitation

Your journey to full mobility doesn’t end in the operating room. A structured rehabilitation program is vital, and may include:

Weeks 1–2: Gentle movement, icing, and edema control. Small, frequent motion exercises to prevent stiffness.

Weeks 3–6: Gradual addition of strengthening and range-of-motion exercises.

Weeks 6–12: Progressively more demanding balance, proprioception, and functional activities.

After 3 months: Sport‑specific or work‑related tasks as tolerated, ensuring full strength and confidence.

Strict compliance with physical therapy is one of the best predictors of long-term success.

Recognizing Risks and Limits

Although generally safe, all surgeries carry some risks:

Infection (rare but possible)

Blood clots

Bleeding or fluid build‑up

Nerve or blood vessel irritation

Recurrence of symptoms or incomplete repair

Plus, not all joint pathology can be managed through small incisions—some extensive tears or reconstructions may still require open access. A frank discussion with your orthopedic provider helps clarify whether this approach suits your specific injury or condition.

Common Conditions Appropriate for Arthroscopic Care

Here are some examples where the minimally invasive route excels:

Meniscal tears: Inner knee cartilage is trimmed or repaired, reducing pain and locking.

Rotator cuff issues: Small tears in the shoulder tissue can be sutured with minimal soft‑tissue disruption.

Loose fragments: Debris in any joint—whether cartilage or bone—can be removed quickly to restore smooth movement.

Ligament repairs: Repair or reconstruction of key stabilizing tissues, like the ACL, often sees faster rehab.

Inflamed joint linings: Overgrown synovial tissue (common in arthritis) can be removed to ease persistent swelling.

The Takeaway

When joint pain threatens your lifestyle, arthroscopy offers a refined solution—smaller incisions, less discomfort, faster recovery, and enhanced diagnostic clarity. Ideal for a wide range of joint issues—from torn cartilage to unstable shoulders—this method has reshaped orthopedic care.

If you’re considering Arthroscopic surgery in Pune, it’s wise to consult a skilled orthopedic professional to ensure the treatment aligns with your condition and recovery goals.

How HPLC Column Works: Principles of Separation Explained

Introduction

High-Performance Liquid Chromatography (HPLC) is a cornerstone technique in analytical chemistry, widely used in pharmaceutical, biotech, food, and environmental labs. At the heart of every HPLC system lies a critical component: the column. But how does an HPLC column actually work? Understanding this process helps analysts improve separation, troubleshoot issues, and choose the right column for their applications.

In this article, we’ll break down how an HPLC column works, covering its internal structure, separation mechanism, and key factors that affect performance.

The Role of the HPLC Column

The HPLC column is the site where the actual separation of analytes occurs. It contains a packed bed of stationary phase particles that interact with compounds in the injected sample. As the mobile phase flows through the column, different compounds move at different speeds, depending on how strongly they interact with the stationary phase.

The result? Each component elutes at a different time, producing a unique retention time that’s essential for identification and quantification.

How HPLC Column Works – Step-by-Step Process

1. Sample Injection

The process starts when the sample is introduced into the HPLC system via an injector and carried by the mobile phase toward the column.

2. Interaction with the Stationary Phase

As the sample passes through the column, each analyte interacts with the stationary phase. The strength and nature of these interactions (hydrophobic, polar, ionic) determine how long a compound is retained.

3. Separation Mechanism

In Reverse Phase HPLC (e.g., C18 columns), non-polar compounds interact more strongly with the hydrophobic stationary phase and elute later.

In Normal Phase HPLC, polar compounds are retained longer.

4. Elution

Each compound exits (elutes from) the column at a different time. The detector records these elution times as peaks on a chromatogram.

Internal Structure of an HPLC Column

An HPLC column consists of:

Tube material: Usually stainless steel or PEEK

Stationary phase: Silica-based particles bonded with functional groups (e.g., C18, C8, phenyl, amino, etc.)

Particle size: Typically 3–5 µm in analytical columns; affects resolution and backpressure

Column dimensions: Common lengths (50–250 mm) and internal diameters (2.1–4.6 mm)

Each of these factors influences how well the column separates your target analytes.

Factors That Influence Column Functionality

Several variables impact how effectively an HPLC column performs: Factor Impact

Mobile Phase Composition Affects elution strength and retention time

pH Alters ionization of analytes and stability of bonded phase

Temperature Influences viscosity, analyte interaction, and column lifetime

Flow Rate Affects resolution and analysis time

Optimizing these conditions is crucial for method development and reproducible results.

Common Questions: How HPLC Columns Work

❓ Is a longer column always better?

Not necessarily. Longer columns may improve resolution but increase run time and pressure. It's about balancing separation needs with practicality.

❓ Can I reuse the same column for different samples?

Columns can be reused, but cross-contamination and degradation over time can impact results. Using guard columns helps extend column life.

❓ What’s the difference between analytical and preparative columns?

Analytical columns are used for small-scale quantification, while preparative columns are larger and used to isolate and collect purified compounds.

Conclusion

Understanding how an HPLC column works is fundamental to mastering liquid chromatography. From the chemistry of interactions to the mechanical design, each element of the column plays a role in achieving sharp, reliable separation.

At Zodiac Life Sciences, we offer a wide range of HPLC columns — including C18, C8, phenyl, and amino — engineered for precision, consistency, and longevity. Explore our selection today to find the right column for your lab's needs.

Modulated Realities

Let us imagine that our reality cannot be fully explained from within itself, but exists as one layer in a multi-tiered system in which higher levels invisibly shape the lower ones. This shaping does not happen through direct causality, but through the imposition of constraints within which the lower levels unfold freely, yet coherently. It is a kind of top-down modulation that does not force, but frames the field of possibility.

A natural model for this idea comes from deep generative neural networks, such as Deep Belief Networks. In these systems, an upper, more abstract layer defines a general pattern — for example, the idea of a “face” or a “number.” The lower layers fill in the concept with concrete details. Crucially, this process is probabilistic: the lower layers retain a great deal of freedom, but only within the boundaries of what fits the higher-level idea. The lower layer is unaware of being guided. It behaves as if its activity were free, though its dynamics are already implicitly structured by a condition from above.

Translated to the physical world, we find a similar structure. We observe only the dynamics at our level — particle interactions, physical constants, and microscopic laws. We take these rules to be fundamental, because they are consistent and locally sufficient. But perhaps this belief is based on a limited perspective. It may be that these laws and constants are in fact effective projections of fixed conditions from a higher level. The laws of nature would then resemble seemingly autonomous behavior patterns that, in truth, fulfill invisible constraints — much like an organism moves freely, yet still expresses its internal blueprint.

This becomes particularly vivid in quantum physics. The collapse of the wave function appears random. Quantum mechanics gives us precise probabilities for individual outcomes, but not the exact sequence in which those outcomes occur over time. Each event fits the predicted distribution, yet the particular ordering of results — the succession of particle detections, for instance — is left undetermined by the theory. This sequence is treated as random, though it obeys long-term statistical patterns.

But what if that randomness is not absolute, but the result of hidden steering signals from a higher level? Then the specific outcomes of measurements — including their sequence — would not be arbitrary, but meaningful realizations of a higher pattern. This pattern would not be directly observable, since it lies outside our level, but it would leave traces in the statistical structure of events. What looks like randomness would become a form of guided openness.

In statistical terms, the universe might be enacting a conditional probability distribution p(v|C), determined by an invisible higher-level constraint C. From our perspective, we see only the local activity and assume it is governed by unconditional laws p'(v). But what if those laws are just what the world looks like when a higher condition is already in place — just as in a generative model, a fixed high-level node induces a new, effective energy landscape E(v1,v2,..) in the layers below?

Top-down modulation, then, is the idea that a higher order shapes the space of possibility for a lower order, without intervening in its actual dynamics. It does not act by cause, but by condition. From within the lower system, this appears as autonomy; in truth, it is a hidden obedience to form. The higher pattern does not manifest in single events, but in statistical structure, in the stability of laws, and in the deep coherence of the world. It might be the true source of the order we observe — not explaining why things happen, but why certain forms are even possible and persist.

PsiQuantum Get Large Cryogenic Plant from Linde Engineering

Cryogenic plant

Linde Engineering will build PsiQuantum's utility-scale quantum computer's cryogenic plant in Australia.

Linde Engineering has won a substantial contract to develop and build a large-scale cryogenic cooling plant for PsiQuantum's utility-scale quantum computer in Brisbane, Queensland, Australia. This endeavour is building the infrastructure needed to get quantum computing from theory to practice.

The cryogenic plant being built to run a quantum computer is one of the largest ever built. Providing PsiQuantum's gear with incredibly low temperatures will be its main task. The facility will cool PsiQuantum's Omega chipset and parts cryogenic cabinets.

The cooling infrastructure is meant to attain and maintain 4 Kelvin (-269 °C, -452 °F) temperatures to ensure the quantum computer's reliability. Only a few degrees separate this temperature from absolute zero.

The nature of quantum computing requires such intense cooling. Unique qubits are employed in quantum computers. Qubits can exist in a coherent superposition of several states, unlike traditional bits that convey information as 0 or 1. Due to this capabilities, quantum computers can perform multiple calculations at once, possibly solving difficult problems faster than regular computers.

Though delicate, these quantum states are highly susceptible to outside disruption. Environmental interactions like heat and electromagnetic radiation can damage qubits' quantum mechanical characteristics. Decoherence can cause system failure or faults. Proper cooling is essential for qubits to work reliably and sustain their fragile quantum states.

Photonic devices underpin PsiQuantum's quantum computing. Photons, not electrons, convey data on these microchips. This photonic technology allows data sharing at the speed of light and maybe at lower energy costs than conventional electronics.

PsiQuantum CEO and co-founder Jeremy O'Brien noted their photonic technology's heat sensitivity. O'Brien stated photons don't sense heat like matter-based qubits. He said this makes their quantum computers “can run 100 times warmer” than others. This “fundamental scaling advantage,” according to O'Brien, is one reason PsiQuantum believes they can swiftly reach utility-scale quantum computing. “It appreciate collaborating with a world-class firm like Linde Engineering to deliver industrial-scale systems with proven technology,” he said, thanking Linde Engineering.

Even though photonic qubits are more thermally durable than matter-based qubits, PsiQuantum's supporting gear demands extremely low temperatures. To reduce signal noise and ensure system stability, this cooling is needed. The cryogenic facility will cool tens of thousands of PsiQuantum Omega photonic chips. These chips will be stored in modular cabinets connected by optical fibre to form a scalable computing system. According to the source, Google and IBM have had cooling concerns where little thermal changes could cause failure.

Linde Engineering can handle this complex project. They are one of the few companies with the expertise to build large cryogenic systems. Linde Engineering has installed over 500 cryogenic plants worldwide, showcasing their expertise. Their expertise includes semiconductor manufacture, magnetic resonance imaging (MRI), and particle accelerator and fusion program maintenance. These usage often involve high temperatures and complex cooling needs, offering Linde tested technology and industrial experience that benefits quantum computing.

According to Linde Engineering Senior Vice President Global Sales & Technology John van der Velden, the relationship is an honour to help PsiQuantum achieve their quantum computing goals. This relationship shows how shared knowledge may advance technology. The technologies created and financed by this project aim to solve some of modern civilization's biggest problems.

The development of this critical infrastructure in Brisbane is expected to have a wider positive impact. It should boost supply chains, university-business relationships, and Australia's quantum ecosystem. The project also highlights the importance of specialised industrial partners like Linde Engineering providing infrastructure for quantum technology adoption.

Utility-level This cryogenic reactor could enable quantum computing, which could revolutionise several fields. This could improve healthcare, energy management, material design, encryption, medicine development, climate modelling, artificial intelligence optimisation, materials science, and cryptography. The term “utility-scale” refers to a quantum computer with adequate processing power to cover its operating expenses for real-world applications.
