Two ropes. Two knots. One principle. Each side wraps twice and tucks back through itself — forming a barrel knot around the opposing rope. When you pull the ends, both barrels slide toward each other and jam. The harder the tension, the tighter the lock. There is no mechanism... show more

🚨 BREAKING: Mathematicians invented a kind of “QR code” for knots. That might sound simple. It isn’t. Knot theory has struggled for decades with a brutal tradeoff: the best invariants are hard to compute, and the easy ones are often too weak to separate complicated knots. This new one appears to do both: powerful enough to distinguish highly complex knots, and efficient enough to handle hundreds of crossings. That could be a serious leap for topology. Could a computable knot “QR code” change how we study complexity in mathematics itself? What do you think? Follow me for more frontier physics and maths.

Have you ever heard of the three-body problem? This video explains a really fascinating and complex concept in a simple way! Here's the idea: When two stars orbit each other, their motion is very orderly and predictable. But when a third star enters the picture, everything falls apart! The gravity of each star affects the other two, creating a completely chaotic and unpredictable cosmic dance. It's like three people trying to dance together with no rules, constantly bumping into each other! No one can say exactly what their next move will be.

My name with a rope Create yours using Seedance 2.5 Prompt : Using the reference image as the exact final frame, create a 10-second stop-motion-inspired fluid CGI animation of a single thick red braided rope forming the word “Smiling” on a pure white seamless background. At the beginning, the rope is loose and unformed, scattered in soft loops across the frame, with 4–5 tiny clay-like miniature characters wearing simple rope-green overalls and no distinct facial features standing around it. They quickly grab the rope and work together, pulling, stretching, coiling, twisting, and tying it into shape. The rope progressively transforms into the cursive letters “S-m-i-l-i-n-g”, moving smoothly from left to right. Each letter must be created entirely from the same continuous rope, with realistic braided fibers, intricate knots, overlapping loops, natural crossings, and clean negative spaces matching the reference image. The characters playfully climb over and around the rope while shaping each letter, coordinating their movements as the word becomes recognizable. The camera remains completely static and top-down, with consistent soft studio lighting, subtle shadows beneath the rope, and no background elements. In the final 1–2 seconds, the characters finish the last knot on the “g,” step back and hop away, leaving the completed “Smiling” rope artwork clearly visible and matching the reference image. No cuts, no camera movement, no independently generated text, no extra objects. Smooth continuous motion, tactile rope physics, realistic fibers, playful miniature stop-motion aesthetic blended with polished CGI.

Double-Slit Experiment ✍️ It shows that tiny things like electrons act like ripples in water instead of solid marbles. When a particle is fired at two slits, it doesn't just go through one or the other; it travels as a wave of probability that passes through both at the same time. These two waves then overlap and interfere with each other, creating a pattern of light and dark stripes on a back wall. This shows that at the quantum level, reality isn't "set" until we actually measure it. It behaves as a spread-out wave of possibilities until the moment it hits a target.

hello we have another angle for this jikook 😩 you can see how they both poke each other at the exact same time and how it's so obvious that jungkook wants to pull jimin into a hug with the way his hand is reaching all the way around jimin’s back 😩

Math says the Big Bang made matter and antimatter in equal halves. They should have erased each other into light, leaving no one to see it. And yet, you exist, because nature miscounted by one part in a billion. Math says nothing forbids a particle from outrunning light. The equations hand it an imaginary mass and let it through. And yet, in a century of looking, not one has ever shown up. Math says you can have a north without a south. Break a magnet, isolate the pole. And yet break it a trillion times, you get a trillion little magnets, each with both ends intact. The universe reads the math and decides what it’s willing to be.

In 1516, Leonardo da Vinci designed a double helix staircase for the Château de Chambord in the Loire Valley, France. This staircase is unique because it consists of two intertwined spiral staircases that allow people to ascend and descend without obstructing each other.

Sometimes a connection enters your field and it's unexplainable, you just remember them. There's no forcing this remembrance. You just know. Both can sit in silence and recognize each other like you've done this a thousand lifetimes before. It's the unspoken energy that forms between two souls that gets woven into the Akashic field, and when you meet again, there's no logic that can define what this is. It's just felt. It's also not about forcing or trying to make sense of it. It's about allowing what's real to move through you effortlessly. Because when the connection is real, you don't need proof. The proof is trusting what you feel. ~ Elizabethcopolla ✨🙌🏽💫

A drive as a first date is bad? - drive around the city you both know - listen to music together - talk to each other - just the two of you - no distractions - can pick her up and drop her off - builds TRUST - speed limit Never tried it with a 2003 Fiat, but get a decent car

there are four types of agent loops. most people only know one. loop engineering is a choice between four structures, each handing off one more job than the last. every one answers two questions: what starts a run, and what ends it. hand-run, you answer both yourself, every time. 1) turn-based → you prompt, it acts, you review, you prompt again. both jobs stay with you. use when requirements are still forming. 2) goal-based → "/goal hit Lighthouse 90, stop after 5 tries." an evaluator checks, a no sends it back. use when the outcome is measurable but the path isn't. 3) time-based → a clock fires, it runs "check the PR, fix CI," then waits. /loop local, /schedule survives a closed laptop. use for recurring work. 4) proactive → no human present. it watches a channel, spawns triage, fix, and a reviewer, closes the task itself. use for standing duties you can't predict. not which one is most advanced. whether your task is exploratory, measurable, recurring, or standing. the more you hand off, the less you babysit. full breakdown in the article below.

Leg curls go first in the session. Not last, not as a finisher, not squeezed in if there is time. The knee is held together by an argument between two muscles. The quads pull the shin forwards, the hamstrings pull it back, and when those two are anywhere near matched the joint tracks properly and the load goes where it should. Now look at how the average leg day is arranged. Squats, presses and extensions while you are fresh, hammering the quads. Then curls at the end, two half-hearted sets, done in a state where you could not produce real force if you tried. Run that for a few years and it stops being an argument. One side has been training. The other has been turning up late. Put the curls at the front and you fix both halves at once. The hamstrings arrive at your heavy squats already switched on, which is the cheapest knee insurance in the building. And they finally get trained fresh, so they actually progress instead of living off the scraps. Four to six reps, heavy, two sets, then go and squat. If your knees already complain, start here. If they don't, this is how they stay that way.

Your body fat is a tank with a tap on it, and the tap narrows as the tank empties. - Plenty of fat: your body covers almost any deficit you ask it to - Getting leaner: it covers less each day - Properly lean: it covers very little, and the rest comes off the plate Which is why the first stone comes off while you barely notice, and the last one takes everything you have. So when you are lean, the shortfall has to arrive as food. And the industry hands you the wrong bag. Push the protein. Two hundred grams. Two fifty. Chicken breast on a kitchen scale. Past what you build with, protein is a fuel your liver has to strip the nitrogen off before you can use a calorie of it, and that machinery has a speed limit. So the extra hundred grams builds nothing and lifts nothing. Protein is what you build with. Fat and carbohydrate are what you lift with. Cut them both to make room for another shake and you have removed the thing that was moving the weight. Fat wins that choice. Twice the energy per gram. Leaves insulin alone, so the fat you are burning is not told to stay put every three hours. Keeps you full. And it is the same fuel your own stores are already releasing. Eat the fat. It is the one thing on the plate that matters more the leaner you get, and the first thing they told you to cut.

this is ACTUALLY insane. shipping one teardown is the demo. this is what the workflow is actually for. your best ad dies in two weeks. you can't run it harder without burning it out, and you can't clone your way out because andromeda clusters the copies into one entity. nineteen never spend. your winner stays a one-shot, which is rough when it's the only thing working. the brands that scale keep the structure that converts and rebuild everything on top of it. same bones, new person, new setting. distinct enough that the algo reads each as its own ad. the production loop isn't there to ship your winner once. it's there to rebuild it twenty times before it burns.

Nature-inspired gripper! 🦎 A chameleon doesn't grab its prey, but its tongue wraps around it. Festo built a gripper that does the same thing, and the mechanism is more elegant than it looks. The FlexShapeGripper is an elastic silicone cap sitting on a water-filled chamber. It works as a double-acting cylinder, one chamber holds compressed air, the other is permanently filled with water. Vent the air chamber, and the water-filled silicone pulls itself inwards. The cap folds over whatever is underneath and locks around its shape. The grip is form-locking, so the object's own geometry does the work of holding it. → Adapts to any shape, including delicate and irregularly shaped items where rigid jaws fail → Can pick up and deposit several objects in one operation → Pneumatic drive, minimal energy consumption → The silicone cap maps directly onto the chameleon's tongue Always good to see the mimicry developments from Festo! :) ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

Trust is the hardest thing to build in finance. This is why ADI Chain is building it twice. Every transaction batch on ADI Chain gets verified by zero-knowledge proofs before it settles. That path has carried the chain since day one, and the cryptography behind it underpins the chain's settlement guarantees. A second verification path is now taking shape alongside it. The same verifier runs inside Intel TDX, hardware that seals off the code and can prove to the outside world exactly what was loaded. Inside that sealed environment, the verifier replays the batch, signs off using the approval format the chain already accepts, and returns the result through the route it always takes. Trust in financial infrastructure is rarely built on a single guarantee. Institutions moving real value want to know that if one check fails, another one still holds. Zero-knowledge proofs confirm the math is correct. A hardware-isolated verifier confirms that the environment producing the result is the one it claims to be. Two different jobs, and neither one replaces the other. This is how ADI Chain is designed to serve the institutions moving onto it.

This is the funniest part. Trump says China treated America right. Iran says China helped it a lot. Iran even says China may receive special consideration over Hormuz transit fees. Both sides think China is on their side. Meanwhile China is standing there like the exhausted class teacher watching two students throw chairs at each other: Can you two stop fighting and finish the memorandum you already signed? That is the difference. America wants obedience. Iran wants survival. China wants the room to stop burning. Not because China is soft. Because China understands something Washington keeps forgetting: war is not strategy. war is a failure of strategy.
