A 91-year-old professor is why Nvidia is worth $4 trillion. His name is Gilbert Strang. He teaches linear algebra at MIT. Every AI model on Earth runs on his course. The course has been free on YouTube since 2005. The videos have earned him nothing.
MIT 18.06 opens with "The Geometry of Linear Equations." No advanced math. Strang takes a system of two equations, draws it two ways, and shows the class that a matrix is a picture, not an abstraction. The row picture is two lines that cross. The column picture is two arrows that sum to a target. Every neural network on Earth operates on the column picture.
Strang first taught linear algebra at MIT in 1962. He wrote the textbook in 1976. It is on every serious engineer's shelf. Every quant fund, every ML lab, every rendering engine at Pixar is running his math.
His central insight is that most people are taught matrices as bookkeeping. That is the first thing to unlearn. A matrix is a linear transformation. A linear transformation is a way of moving space. Once you see the space move, the math stops being algebra and becomes geometry.
The Kalman filter is a linear system. PCA is a linear system. Every gradient step in a neural net is a matrix-vector product. GPT is a stack of matrix-vector products, each one a scene from MIT 18.06 running on a Blackwell GPU.
He retired in 2023 after 61 years at MIT. The course is still up. Watched tens of millions of times.
The chip is $40,000. Strang never asked for a royalty.
Six legged robot is fast! 💨
Back in 2015, a small research team at the Florida Institute for Human and Machine Cognition developed HexRunner.
Their robot reached an estimated 30–33 mph on open ground.
What made HexRunner special wasn’t advanced perception or heavy computation. In fact, it was the opposite.
The robot used a deceptively simple mechanical design: six spring-loaded legs rotating around a central hub.
Instead of stabilizing itself through dense sensing and fast feedback loops, the robot relied on its physical dynamics. Stability emerged from the interaction between mass, springs, and motion.
High-speed legged locomotion doesn’t always require more control software or more sensors.
With the right morphology, the system can naturally fall into stable running patterns, much like animals do.
The control problem becomes simpler because the physics does part of the work.
As modern legged robots chase higher speeds and better efficiency, it stands as a reminder that performance doesn’t always come from smarter algorithms.
Sometimes it comes from designing machines whose physics are already on your side.

Ultrasonic standing waves levitate a water droplet and flatten it into a disk.
When the sound is tuned to the droplet’s resonance frequency, it drives harmonic shape modes that produce these rotating star patterns at the 3rd and 4th harmonics.
Planck didn't believe his own discovery. When he introduced energy quantization in 1900, he treated it as a mathematical trick and spent years trying to reconcile it with classical physics.
Simple proof that the Earth isn't flat.
As a cruise ship sails away, its hull disappears below the horizon before the upper decks and smokestacks.
This happens because Earth is curved.
If Earth were flat, the entire ship would simply get smaller with distance instead of disappearing from the bottom up. It’s one of the simplest observations that has pointed to Earth’s curvature for centuries.
Not knocking quantum physics, just i think theyre using the research to sell supernatural superiority. Like Scientology.
When in reality theyre genetically inferior from excessive hygiene, inbreeding and maybe plain evilness
The pre-last-apocalyptic world probably not far off Victor and Tesla, just went for the grandscale. Before God arose with 3000yrs of perpetual warfare. Probably their work they studied.
Many have noticed that our cities, viewed from above, resemble printed circuit boards with microchips and other radio components.
Sometimes, when looking at photos, it's not immediately clear whether it's a city or a circuit board.
Printed circuit boards, fractal antennas, inductors, conductor connections, and real photos of cities?
And what about the Minotaur's labyrinth and other things that were, for example, in caves? Have you ever heard of tubes that transmit acoustic or radio waves?
Most likely, many buildings, such as the pyramids at Giza, were built according to these principles.
And the pyramid itself could very well have been a kind of antenna.⚡️⚡️⚡️

NASA has released one of the most detailed visualizations ever created of Earth’s ocean currents.
Using data from satellites and advanced ocean models, the map reveals massive rivers of moving water, swirling eddies hundreds of miles wide, and the powerful Gulf Stream carrying warm water from the Gulf of Mexico across the Atlantic.
