Here's my conversation with Don Lincoln about some of the biggest open questions in physics, including dark energy, dark matter, the matter-antimatter imbalance, quantum vacuum, quantum foam, and the quest to unify the laws of physics. Don is a particle physicist at Fermilab who has spent decades working at the frontiers of high energy physics. He is also a great teacher & writer. I highly recommend his courses & books. One of my favorite lecture series he has given is The Evidence for Modern Physics where he breaks down the experiments that validate some of the weird laws of physics we have, and what it would take to validate even the weirder ones. It's not enough to come up with a beautiful theory. You also have to show through experiment that the theory is likely to be correct. This process often doesn't get the love it deserves, even though it's often the most important and difficult part of the scientific process. I ❤️ physics. The conversation is here on X in full and is up everywhere else (see comment).

A NASA fellow claims 5 equations explain 99 percent of the physics that actually runs your world. Understand them deeply and you are set for life. His words. And the way he does it is what makes the video worth it. He does not teach the five as a list. He tells them as one story, where each equation is born from the one before it. F equals ma leads into gravity. Gravity rhymes with the law of electric charge, the exact same shape. That connects to magnetism. Magnetism folds into the wave. And the wave quietly opens the door to relativity and quantum physics. By the end, all of physics feels like a single sentence written by one hand, not a pile of formulas you were forced to memorize. The move that stays with you comes first. He says F equals ma is written the wrong way around, and rewrites it. One tiny flip, and the most famous equation on Earth suddenly means something school never told you. His point for why this matters now: in the age of AI, the people who understand reality itself stay in demand. Everyone else is just memorizing. Five equations. One thread. It is in the video.

Why the character movement in my custom game engine felt janky and how I fixed it. In a game engine, most often, a character moves using the physics engine. Meaning, the player is not just a coordinate in space but a physical body. It has velocity, it handles collisions, and it interacts with the world. Now, as you might know, physics engines need stability. If you run them at variable framerates, things start breaking. Objects phase through walls or fly off into space because the math becomes unpredictable. This is why most game engines lock their physics loop to a 60Hz fixed rate. But here’s the problem: If you have a high-end system, you don't want to limit it at 60 FPS. That's a waste of good hardware. Now, that said, if the GPU is rendering at 144 FPS but the player's position (physics driven) only updates 60 times a second, it creates a micro-stutter that ruins the "smooth" feel of the game. A good way to fix this is to treat the character as two separate things: 1. The Physics Body (Invisible part): This is the "real" character. It lives in the 60Hz physics world, it moves the player and handles collisions. 2. The Visual Model and Camera (Visible part): This is what the player actually sees. It doesn't care about collisions, its only job is to look nice and smooth at whatever framerate the GPU is pushing. Once you have this separation, you can use interpolation to keep them in sync. Every time the physics clock ticks, you save the previous position of the invisible body before moving it to the new one. Between those ticks, calculate how far we are between the last physics update and the next one. By using this to drive the visible parts of the game, the stutters disappear. The physics loop stays fixed behind the scenes, while the visuals slide smoothly between the snapshots. Example: - Right after a tick: blend_weight= 0.0 (The visual model stays at the old physics position). - Halfway to the next: blend_weight= 0.5 (The visual model slides to the middle point). - Just before the next: blend_weight= 0.9 (The visual model is almost at the new physics position). Pro-Tip A critical mistake I made initially, and one many devs make, is parenting the camera and visible parts directly to the player body. If you do this, the camera inherits the discrete 60Hz physics movement by default. In that setup, interpolation won't work because the camera is "stuck" to the physics clock. For this fix to work you must decouple the camera and visuals from the body and move them separately. Player movement processing in Detis Engine: - fixed_process: Physics runs at 60Hz. Handles collisions and raw movement. - process: Variable rate. Mainly used for player input caching in the player case. - late_process: Variable rate. Handles interpolated camera movement after physics and everything else is done being processed. - render. Submits the final interpolated transforms to the GPU. The test environment in the video is running on an old 2070-based laptop. Hopefully the video compression won't introduce any stutter... I’m sharing this in hopes it helps a fellow dev. Cheers.

This reply really proves my point. Professors should teach, but this reads like a copy/paste AI response. NASA people investigated themselves and found no wrongdoing, great, just means its legally classified, which is no surprise because 'UFOs' are nuclear secrets. Dr. Yu does not have access to design/build these craft, that's done by Air Force/Lockheed at sites like Air Force Plant 42. By people like Eric W Davis, which is probably why he's testifying to congress. You really think a physicist with wormhole papers is testifying about aliens? lol Have you read his papers??? Why did General Lanni hold up his teleportation physics study and say it was an example of the kind of research he wanted done in his labs? That doesn't give you pause? If you listened to the engineers they have the answers to your gaps in physics. The Aether is 100% real, and it's quite embarrassing that all we had to do was turn the experiment sideways. That's all it took to completely upend the physics you are so confidently wrong about. Your lack of understanding of physics stems from the incorrect assumption that space is empty. It's really that simple. Einstein's equations are right, space is a medium and if we bend it to an extreme we make a wormhole.

Today our Good Morning community brought the spirit of Giggle Academy into real life together with our partner Fanos Academy. We visited a public school in Oromia, Ethiopia 🇪🇹, outside the capital city, where more than 3,000 students study each day in 2 shifts. This time we focused on the youngest kids. Their excitement, curiosity, and smiles showed us once again why education is the most powerful gift we can give. We could only prepare shirts and learning materials for 30 students, and it reminded us how many more children in the world are waiting for opportunities like this. We will keep going until every child has access to learning, inspiration, and a chance to grow without limits. Free education for every child. That vision is what Giggle Academy stands for. Thank you CZ 🔶 BNB for inspiring a world where knowledge reaches every home and every heart.

An English miller with one year of school rewrote the laws of physics. Nobody noticed. 🏴󠁧󠁢󠁥󠁮󠁧󠁿🧑‍🔬 George Green. Nottingham. 1828. He taught himself mathematics in the back of a windmill. Published a paper on electricity and magnetism. Fifty-one people bought a copy. Most were friends. They couldn't understand it. Five years later he walked into Cambridge. Aged forty. Sat in lectures with teenagers. Graduated fourth in his class. Two years later, he was dead. Aged forty-seven. Forgotten. Until a young scientist found the paper, sent copies across Europe, and changed physics forever. The mathematics Green invented in that windmill became the foundation for electromagnetism, quantum mechanics, and modern engineering. Einstein visited Nottingham in 1930 and said Green was twenty years ahead of his time. Every physics student in the world writes his name on an exam. Most have no idea he was a miller from Nottingham with one year of school. They put a stone for him in Westminster Abbey. Next to Newton's grave. The windmill is still standing. You can visit it. Be part of us. Be Proud Of Us. 🇬🇧 #ProudOfUs

Pressure is not the enemy - it is often the process. When the world feels unstable and life presses in from every direction, it is easy to believe that trouble is a sign of defeat. But Scripture reminds us that pressure is not meant to break us; it is meant to build us. Just as a diamond is formed under intense pressure, God uses adversity to refine His people. The trials you face today are not wasted - they are shaping you into something more valuable than you ever imagined. The Apostle Paul understood this truth firsthand. Though surrounded by hardship, persecution, and uncertainty, he declared victory - not because his circumstances changed, but because his perspective did. When you recognize that God is greater than your trouble, fear loses its grip. In the middle of chaos, Christ offers peace that the world cannot give. So press on. What feels like pressure today is preparing you for purpose tomorrow. The victory is already yours through Jesus Christ.

#WATCH | Hyderabad, Telangana: Supriya Gaud, a relative of the student who was allegedly given religious homework, says, "Yesterday, I went to the school to pick my nephew up and I saw that the contents in his diary was something which is not related to the subject. I saw a teacher writing to read Kalma and Sucralfate. That is absolutely wrong... If you are giving education, just do that. Students from different religions, different aspects are coming to get the education. They're coming for quality education... Kalma and Sucralfate is not a part of the subject, it is a religious book. Do not mix it up. If you want to make it a subject, please put Bhagavad Gita, Bible as a subject... I am really thankful to the school management because they have taken the strict action on this. We have seen the diary and we have raised our voice. I don't know in how many diaries and how many students this has been going..."

One of the greatest crop pictures in history appeared mysteriously near Barbury Castle in July 1991 (slide 1). For many years, nobody knew what it was trying to say! Later I figured out that it describes the horizontal-spin, then rise-precession, of a "spinning top" (slide 2), using 3-phase power. Recently I have reproduced that novel effect in the lab, using 6 wire coils given 3-phase power, and a central spinning magnet (movie 3). In this new movie, I zoomed in, so that you can see details of how it spins and rises around a central aluminum pole, while pressing up on a silicone bead, placed just above. Why did friendly aliens show us such novel physics on Earth in 1991, rather than many other images which could be drawn for our education? Personally I think it describes the underlying physics behind UFO levitation, although that remains to be proven in our own laboratories. Does anyone, among 7 billion people on Earth, wish to study this interesting effect further? Are there any Great Learned Professors of Physics who might be interested? Wait until you find out who has been "talking" with us in the fields. 😁👽🛸

“More than 50 Actors Refused Me for the Lead Role” – Director Manpreet Singh Dhami Opens Up About his film ‘His Story of Itihaas’. Director Manpreet Singh Dhami bares it all as he talks about the uphill battle to bring his ambitious film His Story of Itihaas to life. Produced by Dhami under his banner Panchkarma Films, the project is a bold, thought-provoking tale that many found too gutsy to take on, until veteran actor Subodh Bhave stepped in. The film tells the story of a humble physics teacher who stumbles upon falsehoods in his daughter’s school history textbook. What follows is a gripping battle against the academic and political establishment, as he uncovers a buried truth that could alter the course of the nation’s past — and its future. Speaking about his journey, Manpreet Singh Dhami shares, “This film is not just a script – it’s a mission I’ve lived with for years.

A NASA fellow claims the modern world runs on one equation. Your phone signal, wifi, satellites, this post reaching your screen. All of it obeys one line of math written in the 1860s, before the light bulb existed. His words. The man is Ali Alqaraghuli, a former NASA postdoctoral fellow who now runs two hardware companies. And the way he teaches it is what makes the video worth it. He does not derive the equation. He teaches you to read it. His claim is that school taught you to read math wrong, and one symbol proves it: what you were told is a plus sign is actually something else. Once you see it, the whole equation turns from notation into a sentence. Then he uses that sentence to walk you through how a signal actually gets from your phone to a satellite and back. One viewer called that section straight up magic. It is 4 minutes of it. The comments are the proof. A physics student wrote it explained what a semester with his professor could not. An electrical engineer admitted this is where the equations finally clicked. One person wrote: I cried and I do not even know why. His larger point: the wireless world is not magic and never was. It is one readable line, and reading it is a skill nobody bothered to teach you. One equation. Everything wireless. 14 minutes. It is in the video.

an MIT professor who taught both physics and finance told his class something none of them expected "finance is harder than physics" not as a joke. as a mathematical statement in physics, the laws don't change. gravity works the same today as it did a billion years ago you can run an experiment, get a result, and repeat it forever in finance, the moment you discover a law, the participants learn it too and their behavior changes the system you just measured in physics, electrons don't read your paper and start moving differently in finance, traders do. every published edge gets arbitraged away by the people who read it this is why quant models have a half-life and physics equations don't Newton's laws: 300+ years and counting Long-Term Capital Management's model: worked perfectly until it didn't, lost $4.6 billion in 4 months the system you're modeling is aware of you modeling it that's not a solvable problem. it's a permanent condition and the quants who survive are the ones who build for it instead of pretending it doesn't exist > this lecture: MIT finance series, free, public, 53 seconds > LTCM collapse: 1998, Nobel Prize winners, $4.6B loss > Renaissance's solution: never stop researching, replace signals before they decay > average lifespan of a quant signal: 2-5 years before it's crowded out retail builds one strategy and trades it until it breaks quant desks build a research engine that produces new strategies faster than old ones die that's not a difference in skill. it's a difference in understanding what game you're actually playing full breakdown in the video below

He was called the strangest man in physics. Not the brightest. Not the fastest. The strangest. But here's what they never told you about him. His name was Paul Dirac. Born in Bristol, 1902. His father had one rule: you could only speak to him in French. When young Paul couldn't find the words, he stopped speaking entirely. That silence became a superpower. At 25, he wrote a single equation that united quantum mechanics with Einstein's relativity. Two pillars of physics that nobody could connect. A quiet boy from Bristol did it with a pen. Then his equation predicted something impossible. A mirror particle. Matter that shouldn't exist. Other scientists said he was wrong. Dirac said nothing. In 1932, they found it. Antimatter. Exactly where his equation said it would be. They gave him the Nobel Prize. He nearly REFUSED it — he hated publicity so much. They offered him a knighthood. He turned that down too. Didn't want to be called Sir. He was given Newton's chair at Cambridge. Held it for 37 years. Barely spoke a word. Today every MRI scanner uses his equation. Every particle accelerator is built on his work. Every smartphone chip traces back to his mathematics. His memorial stone lies in Westminster Abbey. Right next to Newton. The greatest British physicist since Newton. And most of Britain has never heard his name. Until now. Be part of us. Be Proud Of Us. 🇬🇧

🔱Professor S. Lakshmi Bala of IIT Madras has published a free course on quantum mechanics, studying the three-level atom. MIT charges $80,000 to sit in a room and learn this. She didn't ask for a dollar. IIT Madras has a sub-1% acceptance rate. The students in that lecture hall competed harder to get in than most Ivy League applicants. You can watch the same lectures without applying anywhere. The course covers linear vector spaces, quantum state formalism, and the three-level atom - the math behind lasers, MRI machines, and quantum computers. Not a simplified intro. The real thing, from first principles. NPTEL built this. 7 Indian Institutes of Technology and IISc pooled their top professors and filmed the actual university curriculum. Thousands of courses. All free. Almost no one outside India knows it exists. Physics departments in the US have known for years that this content is available at no cost. They keep charging $80,000 anyway. 🔖Watch and save it before someone decides free access to elite education is a threat to the business model.

To promote Narendra Modi’s Shala Praveshotsav school enrollment initiative in Gujarat, Chandreshbhai Borisagar, a school teacher from Amreli, creatively adapted the folk tune Pankhida into an impactful educational awareness song. Riding from village to village on his two-wheeler with a board in tow, he inspired countless parents and children to embrace the power of education. On #TeachersDay in 2010, a meeting with then Chief Minister Narendra Modi gave his mission new direction and renewed purpose. He was later honoured with the prestigious National Award for Teachers and invited to interact with PM Modi at his residence, an unforgettable moment that continues to fuel his lifelong dedication to shaping young minds. He was deeply moved when the Prime Minister, upon hearing his surname, fondly recalled his grandfather - a well known writer of Gujarat. This is more than just the story of one teacher’s recognition — it’s a testament to the inspiration drawn from PM Modi, which continues to empower every teacher like Chandreshbhai to continue their mission of transforming young lives across the nation. Happy Teachers’ Day! #TeachersDay2025

When Ashok Jain, a US-based doctor from Rajasthan was asked to help build a single classroom in his village, his mother asked a simple question: “What will happen with one room?” That question changed everything. What began as a small contribution turned into a large-scale school in Jalore, built on the very land where children once studied with limited resources. Today, the campus stands tall with modern classrooms, better facilities, and a design that resembles the structure of India’s Parliament. Built through personal effort and community support, it’s more than just a school, it’s an opportunity for generations. At its heart lies a mother’s vision: If you give, give in a way that truly changes lives. This story isn’t just about infrastructure. It’s about going back to your roots, and rewriting the future for others. This Doctors' Day, we celebrate doctors like Ashok Jain who don't just heal patients—they build opportunities, empower communities, and leave behind a legacy that transforms generations.

“I am also an Indian.” Four simple words. A lifetime of meaning. When IPS Officer Robin Hibu said it, he opened a wound, a memory, a truth that many from the Northeast carry quietly. In his voice lives the pride of a people who have always belonged to this land, and the pain of being asked to prove it. The Northeast — so often misunderstood, overlooked, reduced to the margins — yet deeply woven into the story, the struggle, and the soul of India. At a time when divisions grow louder, his words remind us what the idea of India truly stands for — not sameness, but shared humanity. Not exclusion, but inclusion. Not where you are from, but how we stand together. Because the Northeast is not separate from India. It is India. In every culture, every language, every sacrifice, every dream. #IndianIdentity #UnityInDiversity #NortheastIndia [IPS Robin Hibu, IPS Officer, Indian Diversity, Northeast India]
