Welcome to Quantum on the Treadmill.Over the past few months, I’ve been trying to understand quantum physics—and honestly, it hasn’t been easy. I’m not a physicist, and equations aren’t naturally how I think. Instead, I ask strange questions: Why whole numbers? What is Planck’s constant? And why did anyone believe these ideas in the first place?Most of these questions came to me while walking on the treadmill. So I began using AI to challenge my assumptions, explore the history, and help me make sense of the science.Then I realized I could automate almost the entire creative process without stepping off the treadmill—from capturing the conversation and organizing the ideas to creating the script, audio, and visuals.This series is an experiment in learning, exercise, AI, and curiosity.

    18 - The Cat

    Schrödinger’s Cat is one of the most famous thought experiments in science—and one of the most misunderstood. In this visual guide, we unpack why Erwin Schrödinger imagined a cat in a sealed box, why the thought experiment was meant as a critique rather than a celebration of quantum weirdness, and what it reveals about the measurement problem. We explore: •How the wave function describes quantum possibilities •Why measurement appears to produce one definite result •What “superposition” means—and why it is not simply hidden information •The double-slit experiment and interference •Decoherence, the Copenhagen interpretation, and Many Worlds •Wigner’s Friend and the question of when a fact becomes real for everyone •How quantum computers use superposition and entanglement in practice The cat was never really the answer. The cat was the question.

    16 - When the Electron Became a Wave | Schrödinger, Bohr, and the Music Inside the Atomoject

    Bohr gave us a strange new picture of the atom: electrons could occupy only certain energy levels and somehow “jump” between them. But he never really explained why only those levels were allowed. Then Erwin Schrödinger entered the story. Building on Louis de Broglie’s radical idea that matter could behave like a wave, Schrödinger began thinking about the electron not as a tiny planet orbiting a nucleus, but as something more like a standing wave. That changed everything. In this episode of Quantum on the Treadmill, we explore how Schrödinger’s wave equation helped explain where Bohr’s mysterious energy levels came from, why the difference between an orbit and an orbital matters, and what physicists actually mean when they say an electron behaves like a wave. The key idea is surprisingly intuitive: Bohr discovered that the atom could play only certain notes. De Broglie suggested that matter itself had a wavelength. Schrödinger discovered the instrument that produced those notes. And Max Born made the story even stranger by suggesting that Schrödinger’s wave did not tell us exactly where the electron was. It described the probability of where we might find it. That shift, from particles following definite paths to waves describing possibilities, became one of the foundations of modern quantum mechanics. And it leaves us with an even bigger question: If the quantum world contains many possibilities, why do we experience only one outcome? Welcome back to Quantum on the Treadmill, my attempt to understand the people, ideas, arguments, and strange turns that created quantum mechanics, one treadmill session at a time.

    17 - Erwin Schrödingeroject and Biology

    What happens when one of the founders of quantum mechanics asks a biological question? Most people know Erwin Schrödinger for the famous cat-in-a-box thought experiment. But in 1944, he asked something just as profound: What is life? In this video, we follow Schrödinger’s remarkable attempt to understand how living organisms preserve information, reproduce with extraordinary accuracy, and maintain order in a universe that tends toward disorder. From the idea of an “aperiodic crystal” to the concept of a biological “code-script,” his questions helped shape the intellectual path toward molecular biology and DNA. We explore: Why heredity posed such a deep physics problemHow DNA can be stable yet information-richWhat Schrödinger meant by “negative entropy”Why living things are open systemsHow quantum mechanics makes stable molecules—and biological information—possibleWhy Schrödinger did not discover DNA, but helped frame one of science’s most important questionsThe cat may be the hook. But the cell may be the bigger story.

    15 - Order Matters

    Why does the order of operations matter in quantum mechanics? In this video, we follow the surprising path from Heisenberg’s early work on atomic transitions to one of physics’ most famous ideas: the uncertainty principle. You’ll see how Max Born recognized Heisenberg’s strange tables as matrices, why matrix multiplication can produce different results when the order changes, and how that mathematical feature revealed a deep relationship between position and momentum. We also clear up a common misconception: quantum uncertainty is not simply caused by imperfect measurement tools. It is built into the structure of quantum theory itself. In this lesson, we explore: How Heisenberg moved beyond imaginary electron orbitsWhy matrices behave differently from ordinary numbersWhat noncommutativity means in intuitive termsWhy position and momentum cannot both be perfectly sharpWhy uncertainty does not mean chaos or a lack of precise predictionHow a mathematical discovery became a statement about natureMake one quantity sharply defined, and the other begins to blur. If you enjoyed this exploration of quantum mechanics, consider subscribing for more visual lessons on the ideas that reshaped modern physics.

    14 - Hay Fever

    What if one of the greatest revolutions in science began with a hay fever escape to a remote North Sea island? In 1925, Werner Heisenberg travelled to Helgoland to escape severe pollen allergies. There, working with only his notebooks, the sea, and one of physics’ deepest problems, he helped create matrix mechanics—the first complete formulation of quantum mechanics. This video explores why Heisenberg stopped trying to picture electrons as tiny planets orbiting a nucleus, and instead focused on what science could actually measure: energy levels, spectral lines, and transitions between quantum states. Along the way, we unpack matrices, matrix multiplication, why order matters in quantum physics, and how the same mathematical language now underlies modern computing, graphics, simulations, and artificial intelligence. From atoms to computer arrays, GPUs, neural networks, and large language models, this is the story of how a new way of describing relationships transformed our understanding of nature—and helped shape the technological world. Topics covered: quantum mechanics, Werner Heisenberg, Helgoland, matrix mechanics, observable quantities, atomic transitions, matrix multiplication, computation, GPUs, and artificial intelligence.

    13 - Wolfgang Pauli, Unlucky Numbers, and the Problem of Chanceed project

    Welcome to Episode 13 of Quantum on the Treadmill. And because this is Episode 13, I thought we should probably talk about bad luck. Thirteen has had a strange hold on human imagination for centuries. Buildings skip the thirteenth floor. Hotels avoid room 13. Friday the 13th has become shorthand for a day when things are somehow more likely to go wrong. Of course, rationally, we know that makes no sense. There is nothing physically different about the number 13. It cannot make an elevator malfunction. It cannot cause your flight to be delayed. It cannot make you lose your keys. But if something bad does happen on the 13th, we notice it. And we remember it. That is what makes superstition interesting. It may tell us less about the universe than it tells us about how human beings deal with uncertainty. Which brings us back to an old friend in this series: Wolfgang Pauli. We have already talked about Pauli and his enormous contribution to quantum mechanics, particularly the exclusion principle. So I am not going to retell that story here. Instead, I want to talk about another principle associated with his name. One that definitely did not win him a Nobel Prize. His colleagues called it the Pauli Effect.

    12 - La Dame du Radium

    Before we move forward, let’s do a checkpoint and go back in time a little bit. Most histories of quantum mechanics take us to Berlin in 1900 and introduce us to Max Planck. That is where the familiar story begins. Planck is struggling with blackbody radiation, the mathematics refuses to cooperate with classical physics, and he finally proposes that energy comes in discrete packets, quanta. That is a perfectly good place to start. But I want to rewind the clock a few years and travel from Berlin to Paris. Because before Planck could begin rebuilding physics, someone had to help show that the old picture of matter was already falling apart. So let’s spend a few minutes with Mrs. Curie. Or, as she would eventually become known, La Dame du Radium.

    11 - Before Werner Heisenberg Changed Physics, His Father Helped Preserve The Odyssey

    When most people hear the name Heisenberg, they think of uncertainty, quantum mechanics, and one of the twentieth century's greatest physicists. Few realize that before Werner Heisenberg revolutionized our understanding of nature, he grew up in a household devoted to an entirely different pursuit: preserving ancient knowledge. His father, August Heisenberg (1869–1930), was one of Germany's foremost Byzantine philologists. At first glance, that seems worlds away from quantum physics. But it raises an intriguing question: What exactly is Byzantine philology, and what does it have to do with Homer's The Odyssey—or even Christopher Nolan's upcoming film adaptation? The answer is: quite a lot.
