People keep saying that IMAX film is the equivalent to 18K (and now 32K???) and it is driving me nuts. Christopher Nolan is a huge bullshitter and I guess he is just trying to find reasons to keep the IMAX format alive, but saying his film is 18K is silly. We can't even see that much detail even on the biggest screen in the world.

But there is also no lens in the world that is sharp enough to resolve that much detail. They are only now making special 8K-ready lenses.

Film grain is microscopic. And to preserve that grain structure, film is scanned at very high resolutions. You might hear about film being scanned at 12K and so people think film is the equivalent to that resolution. But 35mm is actually fairly soft compared to modern digital cinema cameras. And you have to make the film twice as big to get a similar level of detail to today's high end digital cameras.

And again, the lens is the main bottleneck. If you don't have a sharp lens, it does not matter how many Ks or how big the film is.

Resolution is such a small variable of modern image quality. 4K is probably as much detail as we are ever going to see. But marketers have sold this more Ks = more gooder idea so much and now that is the only thing people know about image quality. The amount of colors, the dynamic range, the contrast... they are all much more noticeable.

But the true secret to image quality... lighting.

Good cinematography is by far the biggest aspect of image quality. Put a 1080p Spielberg movie up against an 8K smartphone recording at a kid's birthday party. Then ask people which looks better.

U Michigan did a press release too, this one talks a little bit more about my specific contributions, I even got to give a quote!

U-M study: Using 'tweezers' to control active fluids reporting by Morgan Sherburne of U-M news

University of Michigan physicists have devised a way to manipulate active fluids, a type of fluid composed of individual units that can propel themselves independently, by taking advantage of topological defects in the fluids.

The researchers showed that they could use tweezers similar to optical tweezers—highly focused lasers that can be used to nudge around atoms and other microscopic and submicroscopic materials—to manipulate the fluids’ topological defects and control how these active fluids flow. The study, led by U-M physicist Suraj Shankar, is published in the Proceedings of the National Academy of Sciences.

You can think of an active fluid like a flock of birds, says Shankar. In a murmuration, an enormous cloud of starlings, birds will twist and turn in unison, making shapes of the cloud. But while the murmuration looks like it’s moving as one organism, the movement is made of individual birds powered by their individual sets of wings.

Similarly, active fluids are composed of individual components like bacteria in water or atoms in a crystal, but each unit moves on its own if shone with light or given “food” via a chemical reaction, according to Shankar. Researchers have previously engineered bacteria so that when they shine light on the bacteria, some bacteria in the liquid swim faster and others swim slower.

“And you can change that pattern as you want. By changing the speed at which the bacteria swim locally, you can paint faces of famous people, or change it and make a landscape,” said Shankar, an assistant professor of physics at U-M.

“Given that these experimental platforms exist and we’re now able to manipulate these materials by controlling the speed by which things are moving around, we asked: Can we develop a framework in which we can control the local speeds of things that comprise active fluids so that we can control them in a systematic way?”

The research team also includes co-authors Cristina Marchetti and Mark Bowick of the University of California Santa Barbara and Luca Scharrer, who conducted much of the research as an undergraduate at UCSB.

The team focused on a popular active fluid called a nematic fluid, composed of liquid crystals—the same kind of liquid crystals that comprise smartphone, tablet and computer displays. These liquid crystals are fluids composed of long molecules that can line up and become ordered like matches in a matchbox or timber logs stacking up and flowing down a river, Shankar says. But when driven by chemical reactions these nematic fluids become active and have the ability to pump fluid, which allows them to move around without externally applied forces or pressure gradients.

Shankar and colleagues used this characteristic feature and applied principles of symmetry, geometry and topology from mathematics to develop design principles that will allow the researchers to control the trajectory of individual crystals within the nematic fluids.

Their methods rely on differences in how these rod-like objects line up within the liquid. They may be misaligned at some points, which causes the liquid crystals to bend around the point of misalignment, like a whirlpool in a river. This creates different patterns in the fluid, similar to the ridges of your fingerprints, Shankar says. In liquid crystals, there are points where the line of crystals will bend over and look like a comet, or form a symbol that looks like the Mercedes logo.

If you add energy to the system and make the fluid active, these patterns, called topological defects, come alive.

“These patterns start moving and they drive and stir the fluid, almost as if they were actual particles,” Shankar said. “Controlling these individual patterns that are associated with the defects seems like a simpler job than to control each microscopic component in a fluid.”

The project began when Scharrer developed simulations to model active fluid flow and track the locations of topological defects, attempting to test a hypothesis posed by Shankar and Marchetti. Showing his simulation results to the other researchers, Scharrer and the team found how these complex responses could be mathematically explained and converted into design principles for defect control.

In the study, Scharrer created ways to create, move and braid topological patterns using what they call active topological tweezers. These tweezers can transport or manipulate these defects along space-time trajectories as if they were particles, by controlling the structure and extent of the regions where chemical activity drives fluid pumping.The resulting motion of the active fluid around the whirlpools of the topological defects enables their never-ending movement.

“I think this work is a beautiful example of how curiosity-driven research, compared to problem- or profit-driven work, can lead us in completely unexpected technological directions,” said Scharrer, now a doctoral student at the University of Chicago.

“We started this project because we were interested in the fundamental physics of topological defects, and accidentally stumbled into a new way to control active biological and bio-inspired fluids. If we’d had that end goal in mind from the beginning, who knows if we would have found anything at all.”

The researchers also demonstrate how simple activity patterns can control large collections of swirling defects that continually drive turbulent mixing flows.

Shankar says while the field is new, and their method is proven using computational models at this point, some day people could use this concept in creating micro testing systems for diagnostic purposes or for creating tiny reaction chambers. Another potential application could be in the field of soft robotics or soft systems, in which computing capabilities could be distributed throughout soft, flexible materials.

“These are unusual kinds of fluids that have very exciting properties, and they pose very interesting questions in physics and engineering that we can hopefully encourage others to think about,” Shankar said. “Given this framework in this one system that we demonstrate, hopefully others can take similar ideas and apply it to their favorite model and favorite system, and hopefully make other discoveries that are equally exciting.”

My first Samsung non-genuine item (w/ my Paper Dolls) [Nov 30th, 2023]

DeviantART Version → [CLICK ME!].

Hello. It is time to share my first experience encountering fake memory storage, particularly "Samsung". I've already tackled a "non-genuine Samsung 870 EVO Solid State Drive", from October 2023. ☝️😮 Now, let's tackle the micro-size memory format of the "non-genuine Samsung EVO Plus SDXC TF Card", and find out what are the details between their "Genuine" and "Fake" Samsung Micro SD Cards, like the SSD before. 🙂

BTW: If you haven't seen my aforementioned "fake Samsung SSD", then please click here. ↓ • My FAKE Samsung 870 EVO Solid State Drive Review [feat. my Paper Dolls] (Recorded: Oct 13th 2013)

So, without further ado, let's get started:

1st Image: ↑

• Alright so, on your left was my genuine Samsung EVO 64GB Micro SD card 👈, which is still functional after 8 years inactive. And this is actually my expandable storage for my old Samsung Galaxy S4 phone [GT-I9505] 📱, which went blacked out the touch screen, in August of 2020. Man, I missed that phone, so much. Then again, my phone was already ancient, as all smartphone brands of this 2020-ish have improved their specs, memory, features, and more than before. And on your right was my first non-genuine Samsung brand of Micro SD Card; the 👉 EVO Plus 128GB, old version. This thing was ordered on Jun 27th, 2020 (from Lazada PH 🇵🇭🛒🌐) for ₱ 378.50 [CLICK ME!], and you can see why there are some red flags on this old EVO PLUS wannabe. 🟥 Also, as of 2023, it was already out of stock, permanently when the new looked Samsung flash memory cards was out on store shelves, both physical and digital. Not to mentioned, new security features was added to prevent counterfeit ones. So, let's bring down the details between these two Micro SD Cards, shall we?

• First: the letters. They're both identical to "Samsung" brand 🔠, but don't mind their colors and their quantity of memory sizes, as well as others. Since I don't have the original 128 GB of an old EVO Plus, I'm settle in with my owned 64 GB EVO. 🟩👍 The new EVO Plus, BTW, and other Micro SD cards have already improved their appearance, since 2021. However, that's where their identical end because on the fonts of "128 EVO" we're bold over the genuine counterpart's thin fonts. 🟥👎 Also, the "Samsung" brand on the fake one was slightly different from the genuine one. 🟥👎

2nd Image: ↑

• Second: the materials. Genuine Samsung micro SD cards had a distinct while line, both old and new appearances. Making it their signature unique look 🟩👍 compared to the rest of the memory brands and counterfeit ones on the same format size. And speaking of, this counterfeit Samsung Micro SD card didn't have that unique appearance, as you could see a solid black line was spot on right through our eyes. 🟥👎 As for their materials, they're both identical albeit the fake one was used as a cheap generic one 🟥👎 instead of Samsung's genuine material circuitry process.

3rd Image: ↑

• Third: the numbers/codes. Another Genuine Samsung micro SD card was the numbers codes facing different approaches (rotating upward) compared to the counterfeit ones. 🟩👍 And for the latter was using generic number codes, that already existed by numerous copycat micro SD card clones. Or something... 🟥👎 I mean, c'mon. Take a look at your right side. We've already seen it, many times, if you're a memory SD card enthusiast (of course). Unlike the Samsung memory brands they create and generate different unique number codes per memory card, and even serial numbers to prevent fake versions of their memory brands. And uhh... Did I mention, that Samsung's flash memory cards are "Made in Philippines"? 🇵🇭🟩👍 Heck yeah! #PusoPinoy, baby! 😁❤️💙💛 If you see that via the microscopic device, you know that your purchased Samsung EVO micro SD cards are 100% Genuine! Though, sometimes they're "Made in Korea" 🇰🇷 (more specifically "South Korea"), so that counts, too. 🙂🟩👍

1st & 2nd Screenshots: ↑

• And Finally: Transfer read/write speed test & Experience used. A genuine flash memory card brand from the likes of Samsung, Sandisk, Lexar, and many more can deliver a fairly high speed/write rate. From a standard 100 MB/s to a massive 200 MB/s, the latter was for 1TB (to sometimes 2/4TB) SDXC cards (which are very expensive price tags). No matter what you choose, that depends on your budget. But at least, the quality of the flash memory brand could satisfy your experience, and their lifetime could last long. But, what about the fake ones? Could they have the same quality treatment? Well, as you can see, using the trusty "Crystal Disk Mark" software and my trusty UGREEN USB Card Reader plugging through the USB 3.0 port 🪟 🖥️, the counterfeit Samsung EVO Plus (128GB) didn't pass the potential transfer speed. 🟥👎 Only a "Genuine" EVO Plus of Micro SD cards should deliver "Up to 100MB/s Read and 60MB/s Write speed with Class 10 and U3 compatibility". And speaking of, my Genuine EVO 64GB passed the quality speed test, and according to their official website, it delivers "Up to 100MB/s Transfer speed with Class 10 and U1 compatibility". Sure, it may not deliver the 100 MB/s given that my old EVO marks 8 years of functionality, but it's good enough for me to transfer my precious files onto my EVO SDXC card without a single corrupt file (as of 2023). 🟩👍 On the other hand, the fake one had already suffered corrupted files in any format, since October of 2023. 🟥👎 My mom was using it, and she was devastated by lost snapshots. So, she decided to buy a different brand with an equal standard quality as my old Samsung EVO.

4th Image: ↑

• So, you two. Did you see who is the legit Samsung memory card brand? And their saying "Yes, it is the orange card one!" Indeed it is. 😁

Overall:

• After we've seen some differences and a short speed test, it concludes, that this Samsung 128 GB EVO Plus Micro SD Card was a wannabe memory card brand, or as I said a "non-genuine" one. So, the question was, did I refund my E-Cash after showing off some red flags on that fake Micro SD Card? 🤔 Well, yes! It was a success 🙂, and I decided to buy a different decent brand called "Strontium". As of today, I'm still using the 256 GB on my Honor 8C phone [CLICK ME!], and my 64 GB now acting as a thumb drive with my trusty card reader! (UGREEN) Without hiccups or a single malfunction on these two, whatsoever. 😊 So, as I said before and I could say it for counterfeit items, "Never judge an item by its seller". ☝️😯

Well, that's the end of my topic. The last topic will be something to save. Coming this December of 2023. 😊

People struggling with “long Covid,” or the persistence of symptoms after an initial Covid-19 infection, can face cognitive difficulties such as “brain fog” and memory problems. Now, a study finds the severity of these symptoms is comparable to the brain aging ten years.

By testing the mental speed and accuracy of participants who had and had not been diagnosed with Covid-19, researchers found the cognitive decline was worst for people who had experienced Covid symptoms for more than 12 weeks, according to a study published this month in eClinicalMedicine, a journal published by The Lancet.

“The fact remains that two years on from their first infection, some people don’t feel fully recovered, and their lives continue to be impacted by the long-term effects of the coronavirus,” Claire Steves, a co-author of the study who researches aging and mental health at King’s College London, says in a statement.

Since the Covid-19 pandemic’s early days, scientists have raced to understand the symptoms associated with long Covid, such as depression, major fatigue, brain fog and even dementia.

In 2020, a separate team of researchers examined the brains of people who had died from Covid-19 and discovered their blood vessels, which were covered with antibodies, had sustained significant damage, reports Time’s Jamie Ducharme. The scientists concluded the virus had somehow caused the body’s immune system to attack its blood vessels, leading to inflammation in the brain.

It’s not clear whether this inflammation is the cause of brain fog and cognitive difficulties in living patients with long Covid, but Lara Jehi, a researcher at the Cleveland Clinic who was not involved in the current study or the 2020 research, tells Time she’s seen it impact both people with long Covid and Alzheimer’s disease. “We found many areas of overlap between the two, and these areas of overlap centered on…inflammation in the brain and microscopic injuries to the blood vessels,” she tells the publication.

To better understand long Covid’s effect on the brain, the new study put more than 3,000 participants through 12 different types of cognitive tests designed to measure memory, processing speed, attention, motor control and other thinking skills. A little over half of the participants had previously tested positive for Covid-19, and all were recruited through the Covid Symptom Study Biobank smartphone app.

In the first round of testing in 2021, researchers found the cognitive impairment associated with long Covid was clear, comparable to the brain being under “mild or moderate symptoms of psychological distress,” or ten years of aging, write the authors in the paper. During the second round of testing, which took place in 2022, patients showed no significant improvement. At that point, some participants’ cognitive decline had lasted nearly two years after infection.

The positive takeaway? Once a person’s Covid symptoms disappeared—regardless of whether they had persisted for three months or one week—their cognitive function appeared to recover.

This, at least, is “good news,” says Nathan Cheetham, a senior postdoctoral data scientist at King’s College London and study co-author, in the statement.

“This study shows the need to monitor those people whose brain function is most affected by Covid-19, to see how their cognitive symptoms continue to develop and provide support toward recovery,” he says in the statement.

About 15 percent of U.S. adults have experienced long Covid, according to the Household Pulse Survey by the National Center for Health Statistics. In the United Kingdom, about two million adults were impacted by the persistent condition as of January 2023, reports the Guardian’s Geneva Abdul.

Steves calls for more research into how long Covid victims can be aided in their recovery process, especially those who have been living with the symptoms for years.

“We need more work to understand why this is the case and what can be done to help,” she says in the statement.

Researchers detail never-before-seen properties in a family of superconducting Kagome metals

Dramatic advances in quantum computing, smartphones that only need to be charged once a month, trains that levitate and move at superfast speeds. Technological leaps like these could revolutionize society, but they remain largely out of reach as long as superconductivity—the flow of electricity without resistance or energy waste—isn't fully understood.

One of the major limitations for real-world applications of this technology is that the materials that make superconducting possible typically need to be at extremely cold temperatures to reach that level of electrical efficiency. To get around this limit, researchers need to build a clear picture of what different superconducting materials look like at the atomic scale as they transition through different states of matter to become superconductors.

Scholars in a Brown University lab, working with an international team of scientists, have moved a small step closer to cracking this mystery for a recently discovered family of superconducting Kagome metals. In a new study, they used an innovative new strategy combining nuclear magnetic resonance imaging and a quantum modeling theory to describe the microscopic structure of this superconductor at 103 degrees Kelvin, which is equivalent to about 275 degrees below 0 degrees Fahrenheit.

Gadgets and Gizmos that inspired Adam Smith

Virginia Postrel at Reason.com:

Pocket gadgets were all the rage in Adam Smith’s day….

The best known are watches. A pocket timepiece was an 18th century man’s must-have fashion accessory, its presence indicated by a ribbon or bright steel chain hanging from the owner’s waist, bedecked with seals and a watch key. …

… At a coffeehouse, a gentleman might pull out a silver nutmeg grater to add spice to his drink or a pocket globe to make a geographical point. The scientifically inclined might carry a simple microscope, known as a flea glass, to examine flowers and insects while strolling through gardens or fields. He could gaze through a pocket telescope and then, with a few twists, convert it into a mini-microscope. He could improve his observations with a pocket tripod or camera obscura and could pencil notes in a pocket diary or on an erasable sheet of ivory. (Not content with a single sheet, Thomas Jefferson carried ivory pocket notebooks.)

The coolest of all pocket gadgets were what antiquarians call etuis and Smith referred to as “tweezer cases.” A typical 18th century etui looks like a slightly oversized cigarette lighter covered in shagreen, a textured rawhide made from shark or ray skin. The lid opens up to reveal an assortment of miniature tools, each fitting into an appropriately shaped slot…. An etui might contain drawing instruments–a compass, ruler, pencil, and set of pen nibs. It could hold surgeon’s tools or tiny perfume bottles. Many offered a tool set handy for travelers: a tiny knife, two-pronged fork, and snuff spoon; scissors, tweezers, a razor, and an earwax scraper; a pencil holder and pen nib; perhaps a ruler or bodkin. The cap of a cylindrical etui might separate into a spyglass.

Parallels to today’s smartphones and other pocket gadges are obvious. Mike Elgan discusses them in this prescient 2010 column predicting the return of the wristwatch:

Five years after Mike published his column, Apple introduced the Apple Watch. I did not wear a wristwatch when Mike published his column, but I do now.

Mike also wrote a column titled “Why Smartwatches Failed” in 2017. Nobody bats 1,000.

Glow-up Pics

Fluorescence microscopy paints beautiful pictures of living things. By attaching fluorescent proteins to molecules, scientists can track them in cells and find out how they work. This technology has enabled countless discoveries, but it can cost around £100,000. What if your lab can't afford that? And how can students get their hands on this equipment? Researchers in the USA may have the answer: a $50 fluorescence microscope they call the glowscope. In video tutorials, they explain how to build one from LEDs, a smartphone, and coloured plastic. Here, we see pictures of zebrafish embryos captured with glowscopes using six different smartphone cameras. They all show that a molecule (green) is restricted to a small area of the brain, which requires high sensitivity and resolution. Thanks to its low cost and simple design, the glowscope may soon bring the magic of fluorescence microscopy to a classroom, museum, or kitchen table near you.
