A donut (torus) has the exact same volume and... surface area as a cylinder with radius r and height 2πR! Watch every swivel preserve both perfectly... Geometry just got delicious!show more

On Apollo 15 mission astronaut David Scott dropped a... hammer and a feather on the Moon and something unbelievable happened, with no air resistance both hit the surface at the exact same timeshow more

What incredible luck that a dog just happened to... attack at the exact same height and angle as Karen Read’s shattered taillight. What are the odds?!show more

Added "corner radius" / rounding, which is easy to... apply to any SDF shape that has an exact (outer) distance function - just subtract the radius from the scale and then offset the computed distance by the same radius. So you get rounded shapes "for free" with 1 subtraction. 1/show more

We got Bambam’s “everyday every night feel like a... fool you gotta know” 10 years later and he sounds the exact same as the 2015 version 😭😭show more

made my first fired alumina print! lightcell energy 🔆... maybe i’ll call it a “lattice flame tokamak” 😉 this is where the flame occurs, held in place like a smoke ring. it’s supposed to be where the hot air and fuel mix, with channels pointing inward along a torus. the flame rolls around mixing fuel air and salt, like a rolling vortex, like a smoke ring. i constructed the geometry like this, it’s a triply-periodic minimal surface (TPMS). this divides a cylinder into two interlaced volumes with minimal material and the maximal surface area. it’s a “Schwartz-Diamond” type minimal surface with a bias, in cylindrical coordinates. the TPMS divides a space into two interlaced volumes. if you delete the material dividing these volumes then this is where the fuel and flames with mix and the reaction will take place. in addition, on average the channels will be pointed in along the torus throughout, canceling momentum and holding on to a recirculation vortex, there a flame will remain lit and where sodium can mix in via salt conducted in via wall surface tension, like a wick, and evaporation. the TPMS curves in all dimensions, so it is quite resistant to thermal stresses, can relieve stain along any of its curves. and it has thin walls so it can easily diffuse gases during debinding and sintering. had a small collapse in the center (probably a singularity in the model, cylindrical coordinates) but fired it anyway and it sintered beautifully! i used the latest version of Hyperganic hydesign for the geometry and a Formlabs Form 4 in Alumina 4N to do the printing. 💁🏻‍♀️☸️show more

If you haven’t tried Cybertruck’s steer-by-wire and 4-wheel steering... system, you must. It has the same turning radius as a Sedan.show more

This dude just got a block and a dunk... in the same sequence without really jumping 🤯 Watch here:show more

The 2026 Hyundai Palisade has a boxier look and... updated powertrains with both a V-6 and a four-cylinder hybrid setup being offered on U.S.-spec models. Hyundai is also launching a rugged XRT Pro trim with more ground clearance and a terrain-mode drive selector.show more

the NBA really thinks these are both equal? LeBron... is literally yelling and grabbing a ref and it's the same kinda technical as what Brooks got for THAT?show more

I find my eyes pulled to Syracuse TE Oronde... Gadsden II every time I watch the Orange offense. Two time All-ACC TE -- converted from WR after his freshman year. Natural catcher with a big radius. Enough burst to beat LBs to the corner. Tough and has the want-to as a blocker.show more

Happy Monday! We just added raycast sensors to mjlab.... They let a robot sample the scene with virtual rays, returning distances and surface geometry. Rays can use orthographic projection for terrain scanning or perspective projection for simulating a depth camera.show more

I've made peace with this years ago, and I'm... not surprised Raimi has as well. His Spider-Man movies were from a different era that can't be replicated the exact same way nowadays.show more

Every fighter's got a dream - and she's got... the magic to make it real! Chibi Spirit Blossom Lillia has joined from the sidelines with a gentle heart and a mean wallop.show more

Just a heads up that you should never be... rendering 10,000 lines of anything, especially if all the lines are the same height, as in code. List virtualisation is a very old and simple technique. You can experiment with the below atshow more

This video looks like a rotating wheel. But watch... just one single sphere. It never rotates. Every ball only moves in a perfectly straight line back and forth. This is simple harmonic motion where linear position follows: x = R cos(ωt) By perfectly offsetting the timing of each straight path, the collective motion creates the illusion of rotation.show more

Every cut, angle, and surface here is the result... of extreme precision controlled down to fractions of a millimeter. CNC machining turns solid metal into complex, perfectly balanced components that move with almost no resistance.show more
