God I want to learn physics so bad but it’s so hard because while I’m learning the concepts and the meanings of things, I still don’t know how to think of it myself. I understand the words and what they mean but if you ask me to figure out a problem in quantum mechanics or particle physics, then I’m lost.

Exploring the Vast Frontier of Physics: A Journey Through Various Branches
Title: Exploring the Vast Frontier of Physics: A Journey Through Various Branches
Introduction:
Physics, the fundamental science that seeks to understand the laws governing the natural world, is a field of endless fascination and discovery. Spanning from the mind-boggling expanses of the universe to the tiniest particles that make up matter, physics encompasses a diverse array of branches that collectively unravel the mysteries of our universe. In this article, we embark on a journey through various branches of physics, exploring the incredible concepts and breakthroughs that have shaped our understanding of the world.
Classical Mechanics:
Classical mechanics, often referred to as Newtonian mechanics, is the branch of physics that deals with the motion and behavior of macroscopic objects. Developed by Isaac Newton, this branch encompasses the famous laws of motion, such as Newton's laws of motion and the law of universal gravitation. While classical mechanics successfully describes the behavior of everyday objects, it becomes inadequate when applied to extremely fast-moving or tiny particles.
Quantum Mechanics:
Quantum mechanics, a revolutionary branch of physics, challenges our intuitions and reveals the strange and fascinating nature of the microscopic world. It describes the behavior of particles such as electrons and photons, incorporating concepts like wave-particle duality and quantum superposition. Foundational theories like Schrödinger's wave equation and the Heisenberg uncertainty principle have allowed us to explore the mysterious properties of subatomic particles, leading to incredible technological advancements like quantum computing and cryptography.
Thermodynamics:
Thermodynamics, often considered the science of energy, explores the principles governing the transformation of heat and work into useful forms of energy. It studies temperature, energy transfer, entropy, and the behavior of systems in equilibrium and non-equilibrium states. Thermodynamics has applications in diverse fields, from engineering and refrigeration systems to the study of black holes and the early universe.
Electromagnetism:
Electromagnetism is the branch of physics concerned with the interaction between electric and magnetic fields. James Clerk Maxwell's equations unified the understanding of electricity and magnetism, revealing the electromagnetic nature of light and paving the way for the development of technologies like electric power generation, communication systems, and electromagnets used in medical imaging.
Particle Physics:
Particle physics delves into the fundamental constituents of matter and their interactions. It explores the behavior of subatomic particles and the forces that govern their interactions. Particle accelerators like the Large Hadron Collider (LHC) have allowed scientists to probe deeper into the nature of matter, leading to the discovery of particles like the Higgs boson and shedding light on the early moments of the universe.
Astrophysics and Cosmology:
Astrophysics unravels the mysteries of the universe on a grand scale. It investigates celestial objects and phenomena, ranging from galaxies and black holes to the origin and evolution of the cosmos. Cosmology, a subfield of astrophysics, aims to understand the structure, origin, and fate of the universe itself. With advancements in observational techniques and theoretical models, we have made tremendous strides in understanding the cosmic microwave background radiation, dark matter, and dark energy.
Conclusion:
Physics, with its various branches, encompasses a grand tapestry of knowledge and exploration. From the classical mechanics of everyday objects to the mind-bending concepts of quantum mechanics and the unfathomable expanse of astrophysics, each branch contributes to our understanding of the laws that govern the universe. The continuous pursuit of knowledge and breakthroughs in physics not only satisfy our innate curiosity but also pave the way for groundbreaking technological advancements that shape our world.

Physicists in the United States, Austria and Brazil have actually revealed that shaking ultracold Bose-Einstein condensates (BECs) can trigger them to either divide into consistent sectors or shatter into unforeseeable splinters, depending upon the frequency of the shaking.
“It’s remarkable that the same quantum system can give rise to such different phenomena,” stated Rice University physicist Randy Hulet, co-author of a research study about the work released online today in the journal Physical Evaluation X. Hulet’s laboratory carried out the research study’s experiments utilizing lithium BECs, small clouds of ultracold atoms that march in lockstep as if they are a single entity, or matter wave. “The relationship between these states can teach us a great deal about complex quantum many-body phenomena.”
The research study was carried out in cooperation with physicists at Austria’s Vienna University of Technology (TU Wien) and Brazil’s University of São Paulo at São Carlos.
The experiments harken to Michael Faraday’s 1831 discovery that patterns of ripples were produced on the surface area of a fluid in a container that was shaken vertically at particular vital frequencies. The patterns, referred to as Faraday waves, resemble resonant modes produced on drumheads and vibrating plates.
To examine Faraday waves, the group restricted BECs to a direct one-dimensional waveguide, leading to a cigar-shaped BEC. The scientists then shook the BECs utilizing a weak, gradually oscillating electromagnetic field to regulate the strength of interactions in between atoms in the 1D waveguide. The Faraday pattern emerged when the frequency of modulation was tuned near a cumulative mode resonance.
However the group likewise saw something unanticipated: When the modulation was strong and the frequency was far listed below a Faraday resonance, the BEC burglarized “grains” of differing size. Rice research study researcher Jason Nguyen, lead co-author of the research study, discovered the grain sizes were broadly dispersed and continued for times even longer than the modulation time.
“Granulation is usually a random process that is observed in solids such as breaking glass, or the pulverizing of a stone into grains of different sizes,” stated research study co-author Axel Lode, who holds joint consultations at both TU Wien and the Wolfgang Pauli Institute at the University of Vienna.
Pictures Of the quantum state of the BEC equaled in each Faraday wave experiment. However in the granulation experiments the images looked totally various each time, despite the fact that the experiments were carried out under similar conditions.
Lode stated the variation in the granulation experiments developed from quantum connections—complex relationships in between quantum particles that are hard to explain mathematically.
“A theoretical description of the observations proved challenging because standard approaches were unable to reproduce the observations, particularly the broad distribution of grain sizes,” Lode stated. His group assisted analyze the speculative outcomes utilizing an advanced theoretical technique, and its execution in software application, which represented quantum variations and connections that common theories do not resolve.
Hulet, Rice’s Fayez Sarofim Teacher of Physics and Astronomy, and a member of the Rice Center for Quantum Products (RCQM), stated the outcomes have crucial ramifications for examinations of turbulence in quantum fluids, an unsolved issue in physics.

This. Fucking this.
Please take your time and read the whole document. It is enlightening and I profoundly agree with every single word written on it. I have a degree in Physics, I work in a university both teaching math/physics (also for high school students) and doing research in particle physics. And this document is completely true. I hate the Math curriculum of schools, and also the Physics one. Since the document is already exhaustive about math, let me talk a bit about Physics.
In High School, they teach you a lot of unuseful stuff. Like, how to solve the problem of a mass falling in a gravitational field, or how to describe the rotation of a rigid body. They are part of Physics, this is true, but the way they are taught removes completely the deep joy of understanding what happens in the world. Physics is not about using mathematical formulas and calculating accelerations and masses and such. Physics is looking at a world-champion in biking, who goes at god knows how many km/h and asking "How the hell does he not fall?" and then trying to bike yourself, and progressively build a good answer. Physics is about throwing a ball and asking yourself how many times will it bounce before stopping, and how you can modify that number, and why. Physics is about seeing the stars in the night sky and asking how the world is up there. Physics is the art of looking to a complicated Universe and finding out it has a beautiful simplicity, a simmetry in any fucking sort of sense. Physics is looking at a twilight and asking "Why is it red, if the daylight seems blue to me?" and then finding out what light is, or isn't, and why does it do that.
Physics is the most real and practical form of wizardry, it is mastering the elements of the Universe and understanding if and how can you bend them.
You don't believe it? Think about what you are doing rn. You are looking at a metal-plastic box which allows you to talk and send sounds and send pictures and even moving images to humans far away, maybe tens of thousands of kilometers. Sometimes protected by wood, or stone, or any other material. You can also create photographs (X rays) that, with no harm, can show you the fucking inside of your body.
To do anything remotely resembling to the modern products of Physics, in D&D I would need at least a level 10-15 wizard. If you told it to someone from more than 100 years ago they would burn you like a bog witch.
It's true, in the operation of discovery you have to calculate something, at a certain point. But it is not pointless, it always starts with a reason and a question. Physics textbook problems ask you to learn a formula and how to move its pieces around, but in a fucking boring way. They tell you to calculate the length of a pendulum given its frequency, but why would you care about it? They don't explain it, and they don't show you why there is a standardized technique to do that. They don't explain thay maybe you wanted to measure the passage of time, and a simple string with a mass attached provided a beautiful way to do it, but you didn't know how to make if oscillate quicker or slower, just for aesthetic sake, or any practical reason (such as: making it the base of some music).
They tell you to learn Archimede's principle and formulas, but they never tell you why should you care about it (spoiler: because then you can learn what floating is! And how to float even if you're bulky! And hence how to build a huge ship to go to your friend's place with all your things and other friends!)
Physics is a beautiful art, because in its real form it does not provide answers, but rather more questions. Math is the same, but on the opposite side of the spetrcum (since it is born in a completely imaginary world). Many of you probably would love physics. And it is easily seen by your "Hey Science Side of Tumblr, can you explain this?" maybe followed by the video of a fireball, or a lightning, or a hurricane. What you did not love (and neither do any physicists I have ever met) is just learning by memory boring stufd you'll never find useful anyway.
the solution to the Mathematician's Lament is to teach calculus in early grade school if not kindergarten & i am being 100% unironic

Ultracold Neutrons Could E DIN-Rail router scape to Another Braneworld
www.inhandnetworks.com
While it might sound like science-fiction, the idea that the Universe is embedded in a broader multidimensional space is something that cosmologists have been pondering. The cosmos might exist in parallel with outer universes in other sets of dimensions. These universes are called braneworlds. If this is an accurate description of what’s happening, then the Universe could end up inside another one.
A few years ago, Michael Sarrazin of the University of Namur in Belgium and his colleagues showed how baryonic matter might make the leap into other universes in the presence of large magnetic potentials. This has provided a theoretical basis for matter swapping.
Today, Sarrazin et al. believe that our galaxy might provide a large enough magnetic potential for this to occur. If this is the case, then it’s conceivable that this phenomenon can be observed in a laboratory setting. Some experiments, involving trapping ultracold neutrons in bottles at L’Institut Laue-Langevin in Grenoble, France and the Saint-Petersburg Institute of Nuclear Physi M2M router cs, are already underway which might prove an inkling on how this could happen.
Ultracold neutrons move so slowly that it’s possible to trap them in bottles that are made up of magnetic fields. The rate of the neutron decay could be partially explained by the result of neutrons jumping from our universe into another. Sarrazin has measured this probability, and it’s about one in a million. T VPN industrial router for commercial and industrial and M2M/IoT applications his doesn’t confirm whether actual matter swapping takes Industrial IoT place, only that when it does, it doesn’t happen very often.
According to some of their theoretical work, if there is a change in the gravitational potential, it should also affect the rate of matter swapping. If they carry out a neutron trapping experiment that lasts a whole year, long enough for the Earth to complete at least on revolution around the sun, and if the decay rate varies, then that could be a strong indication that matter swapping is actually occurring.

Photons entangled to make new form of light
Photons entangled to make new form of light
Photons, the elementary particles that make up light, are known to be fast, weightless and to not interact with each other. But in new experiments, physicists at MIT and Harvard have now created a new form of light, demonstrating that groups of photons can be made to interact with each other, slow down and gain mass.

Physi cloud platform cists Demonstrate Control of a Two-Qubit System
www.inhandnetworks.com
In a newly published study, UCSB physicists demonstrate the high level of controllability needed to explore ideas in quantum simulations.
While the Martinis Lab at UC Santa Barbara has been focusing on quantum computation, former postdoctoral fellow Pedram Roushan and several colleagues have been exploring qubits (quantum bits) for quantum simulation on a smaller scale. Their research appears in the current edition of the journal Nature.
“While we’re waiting on quantum computers, there are specific problems from various fields ranging from chemistry to condensed matter that we can address systematically with superconducting qubits,” said Roushan, who is now a quantum electronics engineer at Google. “These quantum simulation problems usually demand more control over the qubit system.” Earlier this year, John M. Martinis and several members of his UCSB lab joined Google, which established a satellite office at UCSB.
In conjunction with developing a general-purpose quantum computer, Martinis’ team worked on a new qubit architecture, which is an essential ingredient for quantum simulation, and allow wireless m2m ed them to master the seven parameters necessary for complete control of a two-qubit system. Unlike a classical computer bit with only two possible states — 0 and 1 — a qubit can be in either state or a superposition of both at the same time, creating many possibilities of interaction.
One of the crucial specifications — Roushan refers to them as control knobs or switches — is the connectivity, which determines whether or not, and how, the two qubits interact. Think of the two qubits as people involved in a conversation. The researchers have been able to control every aspect — location, content, volume, tone, accent, etc. — of the communication. In quantum simulation, full control of the system is a holy grail and becomes more difficult to achieve as the size of the system grows.
“There are lots of technological challenges, and hence learnings involved in this project,” Roushan said. “The icing on the cake is a demonstration that we chose from topology.” Topology, the mathematical study of shapes and spaces, served as a good demonstration of the power of full control of a two-qubit system.
In this work, the team demonstrates a quantum version of Gauss’s law. First came the 19th-century Gauss-Bonnet theorem, which relates the total local curvature of the surface of a geometrical object, s lte uch as a sphere or a doughnut, to the number of holes in the object (zero for the sphere and one for the doughnut). “Gauss’s law in electromagnetism essentially provides the same relation: Measuring curvature on the surface — in this case, an electric field — tells you something about what is inside the surface: the charge,” Roushan explained.
The novelty of the experiment is how the curvature was measured. Project collaborators at Boston University suggested an ingenious method: sensing the curvature through movement. How local curvature affects the motion can be understood from another analogy with electromagnetism: the Lorentz force law, which says that a charged particle in a magnetic field, which curves the space, is deflected from the straight pass. In their quantum system, the researchers measured the amount of deflection along one meridian of a sphere’s curve and deduced the local curvature from that.
“When you think about it, it is pretty amazing,” Roushan said. “You do not need to go inside to see what is in there. Moving on the surface tells you all you need to know about what is inside a surface.”
This kind of simulation — arbitrary control over all parameters in a closed system — contributes to a body of knowledge that is growing, and the paper describing that demonstration is a key step in that direction. “The technology for quantum computing is in its infancy in a sense that it’s not fully clear what platform and what architecture we need to develop,” Roushan said. “It’s like a computer 50 years ago. We need to figure out what material to use for RAM and for the CPU. It’s not obvious so we try different architectures and layouts. One could argue that what we’ve shown is very crucial for coupling qubits when you’re asking for a full-fledged quantum computer.”
Lead co-authors are UCSB’s Charles Neill and Yu Chen, of Google Inc., Santa Barbara. Other UCSB c computer o-authors include Rami Barends, Brooks Campbell, Zijun Chen, Ben Chiaro, Andrew N. Cleland, Andrew Dunsworth, Michael Fang, Julian Kelly, Nelson Leung, Anthony Megrant, Josh Mutus, Peter O’Malley, Chris Quintana, Amit Vainsencher, Jim Wenner and Ted White, as well as Evan Jeffrey, Martinis and Daniel Sank of Google Inc., Santa Barbara, and Michael Kolodrubetz and Anatoli Polkovnikov of Boston University.
This work was supported by the National Science Foundation (NSF), the Office of the Director of National Intelligence and the Intelligence Advanced Research Projects Activity. Devices were made at the UCSB Nanofabrication Facility, part of the NSF-funded National Nanotechnology Infrastructure Network and the NanoStructures Cleanroom Facility.
