Just learned for the first time that Blender can... actually have negative physics cache! This is immensely helpful for each scene having normal physics from the start instead of starting from frame 1 and slowly turning the physics on from a set up bone position.show more

From another unfinished scene. I think this was the... first time I used the RBC physics addon? I liked the idea that the vehicles could have a tight ceiling clearance.show more

Elon Musk: We've designed Optimus from physics first principles.... “We could not actually buy the actuators for any amount of money. They simply didn't exist. Even though there are 10,000-20,000 electric motors out there of various sizes and shapes, we've had to design every electric motor, gearbox and the controlling electronics from scratch, basically from physics first principles.” Interview at the All-In Summit, September 10, 2025show more

30-second one-takes. Physics that actually holds up. Camera moves... that feel intentional. Characters that stay consistent from start to finish. This is the first AI video demo in a while that made me replay scenes just to see how it pulled them off. Seedance 2.5 is coming soon on Higgsfield, and it's looking like a huge leap for cinematic AI video.show more

Tonight at the house: An intimate AI x Physics... Dinner with Prof. Steve Hsu from Manifold steve hsu, Alex Morisse, Alex Morisse, PhD, Jasper Jasper, and Jeremy Nixon - Automating AI Research. We started off with Alex casually explaining the science behind his stealth deeptech start-up on physics textbooks. A thread on the important questions in AI X physics.🧵show more

We released physics-intern: a simple harness for science problems!... It gets models like Gemini 3.1 Pro to go from 17.7 -> 31.4, thus beating GPT 5.5 Pro. The physics-intern harness can wrap any model and via dedicated subagent boost the performance of the vanilla reasoning models. While I think more and more of these harness capability gains will be absorbed into the models (like prompting tricks disappeared over time) there is a lot to be gained right now by building good scaffolds for those models and integrating tools well. Interestingly, the exception we found that GPT 5.5 Pro actually didn't benefit from the physics-intern harness! Read more about it here: PS: I think the Harness[Model] notation is kind of nice.show more

Came up with a real simple way to make... these flasks look like they have liquid! 💦 1. Model glass & invert the normals 2. Model the liquid 3. Rig the liquid with a bone facing up 4. in engine apply "jiggle physics" with negative gravity #gamedev #unity #blender #animation #b3dshow more

1. Realistic Physics Game (Hexagon Test) Prompt: Create a... HTML, CSS, and javascript where a ball is inside a rotating hexagon. The ball is affected by Earth’s gravity and friction from the hexagon walls. The bouncing must appear realistic. → Tests physics simulation, code planning, and visual realism.show more

this is actually INSANE. we just went from text... memes to full blockbuster meme cinema. someone literally made a giant cat slam captain america and the shield physics look completely real. the internet is never going to be the same.show more

Defying the laws of physics and sticking the landing?... We live for moments like this—but from the warmth of our living rooms, you know? ❄️ Don’t miss a minute of NBCUniversal’s coverage of the 2026 Milan Cortina Olympic Winter Games on the @Peacock app from Feb. 6-22.show more

For years Yann LeCun has argued that generative video... models can't truly learn physics. DeepMind's Physics-IQ benchmark proved him right, reporting "a striking lack of physical understanding in current generative video models". The best one scored just 29.5%. This CVPR 2026 paper finds the fix in LeCun's own playbook. "Inference-time Physics Alignment" doesn't retrain the generator. It steers a video model's denoising at inference using a reward from VJEPA-2, LeCun's Joint Embedding Predictive Architecture. - Won first place in the ICCV 2025 PhysicsIQ Challenge with a 62.64% score, beating the previous state of the art by 7.42%. - Repurpose VJEPA-2's "surprise" score as a reward, then search and rank multiple candidate denoising trajectories at test time. - Why it matters: It's a neat vindication of LeCun's thesis. The pixel-prediction generator alone doesn't get physics, but the JEPA world model approach he champions supplies the physics the video model lacks.show more

On the hunt for natural or chance configurations? You’ve... come to the right place. Here are a few of our favorite patterns: 1) The moiré pattern in physics is the wavy geometrical design that happens when one set of lines (straight or curved) is superposed onto another set.show more

My 3D Model of Malevola from Dispatch is finally... finished! This was a super fun project, I learned how to use hair curves for the first time and also 3D printed the full model! Have a look at the full process video! #blender #b3d #dispatchshow more

When moving at high speeds, you can't just make... quick 180 deg turns due to centrifugal forces. The turning radius for Mach 1 can be as large as 15-20 miles & requires significant space The level of detail on the physics even for JJK anime is absolutely incredibleshow more

Some progress on my CS 1.6 surf mod! ⛷️... It’s accurate enough now that I can’t complete it, starting to feel just like the original. 😄 Any surf experts already spotting obvious physics issues from the video? I’ll put an online demo up tomorrow!show more

Gemini Omni is changing video creation and most people... still don't know what it can actually do. Here are 7 things you can do with it right now: 1. Image to Video in multiple styles: Upload a photo. describe the style. Gemini Omni turns it into a video. cinematic, anime, realistic. 2. Reimagine camera angles: Take any image and visualize it from a completely different angle. no reshooting. just describe it. 3. Change backgrounds: Swap the background of any video through plain conversation. no green screen. no editing software. 4. Change hairstyle: Describe a new hairstyle. Gemini Omni applies it. characters stay consistent across every frame. 5. visualize with moodboards: feed it a moodboard, audio, and a brief. it builds the video around the full creative reference — not just a text prompt. 6. swap characters and objects mid-scene: replace people, props, and objects in an existing video. the scene stays consistent. the physics hold up. 7. edit physics: describe how you want things to move. Gemini Omni adjusts the physics of the scene through conversation.show more
