The Other Side of Mother — For Mother's Day, and For Daughter's Memory The Other Side of Mother is a short film about grief, the body, and the complex bond between mother and daughter. When Xiaoci notices her mother’s eyes turning yellow, she slips into a surreal space between dream and womb – a journey through the terrifying possibility of becoming her mother. The inspiration for this film came from the director's own story. The complex emtions of Xiaoci come directly from the director’s real feelings beside her mother’s hospital bed: I wanted to return to her womb – the one place untouched by death. That is the heart of this film. @PixVerse_

This is the full story of how large language models are built. It isn't magic. It's engineering at an insane scale. Someone has to crawl the entire internet, clean out the ads and porn, and feed 15 trillion tokens into thousands of GPUs running in sync.

AI training is about matrix multiplication. CPUs failed at it. GPUs took over. Then came the memory wall. Now, the industry is stitching multiple dies together to act as one. This isn't just hardware. It's the physics of intelligence. Story in the video 👇 youtu.be/epZ3ZQ1Gofo

The history of AI is the history of humans letting go. It goes through three stages: from early expert systems where humans wrote every rule, to deep learning where machines found patterns themselves, to the emergence that created large language models. This video breaks down what "intelligence" actually means in engineering terms. The full story 👇 youtu.be/X0DsGEq-bFQ

What's the essence of GPT? Tokens. Self-attention. Trillions of calculations. That's not about thinking, just probability.

New memory results worth a look: EverMind reports scaling to 100M tokens! Let’s see how they broke the memory limit and made long-term memory possible.

Wheeler said: “No phenomenon is a real phenomenon until it is an observed phenomenon.” We don’t just watch the universe—we help create it by looking at it. What does this mean for reality?

The cat in the box is both alive and dead—until you open it. This is the absurdity of quantum superposition. Do you think this is a real feature of the universe, or just a flaw in our theory?

The Many-Worlds Interpretation solves the measurement problem by saying all outcomes are real. But it also means the universe is infinitely splitting every second. Can you wrap your head around this?

This is the guest house at Niels Bohr’s institute, where Schrödinger was defeated in debate. Bohr argued tirelessly that quantum jumps are real, even when Schrödinger fell ill.

Wave function collapse: the moment the quantum world becomes “real.” But what counts as an observation? A human? A camera? A cat? This question split the physics community.

This snow-covered Swiss villa is where Schrödinger wrote his famous equation. He escaped here with an old lover during Christmas 1925, seeking inspiration away from the chaos of quantum debates. It was the moment quantum mechanics found its most elegant equation.

The equation on the board is Schrödinger’s masterpiece. It describes how quantum states evolve over time. But he misinterpreted it at first—thinking the wave was the electron itself, not a probability. What’s your take on this?

A prism splits white light into a rainbow. Newton said this proves light is particles. But we now know it’s both particles and waves. What’s the most surprising thing about light?

Niels Bohr explained light’s dual nature: it’s both a wave and a particle. Which one you see depends on your experiment. Is reality just what we measure?

The photoelectric effect: violet light knocks electrons loose, but red light doesn’t—even if it’s bright. Einstein said light is made of energy packets (photons). Is light a particle again?

Poisson thought a bright spot in a shadow was impossible. He used it to mock the wave theory. But Arago did the experiment—and the spot was there.

The double-slit experiment shows light interferes like a wave. But if you watch closely, it acts like particles. This is the start of quantum weirdness.

This book, Opticks, controlled how we thought about light for over a century. But it was wrong in key ways.

Robert Hooke was a brilliant scientist, but Newton tried to erase him. Hooke said light is a wave. Do you think Newton’s ego held science back?
