Be the change you want in the world. (Past, Present, Future)=(electron, proton, neutron)= (2^0, 2^1, 2^1+2^0) 2^2=gravity! #PiratesOfPhysics



















The most powerful thing I’ve learned this week: When Copernicus introduced heliocentric theory — the Sun at the centre of the solar system — it actually fit the astronomical data worse than geocentric theory. Ptolemaic geocentric theory had been refined for more than a millennium, with astronomers adding epicycles, deferents, and other adjustments to make it match the observations available at the time. By contrast, heliocentric theory was new, and Copernicus assumed circular orbits, which made its predictions very inaccurate. It took almost a century for Kepler to realise that planetary orbits are not circular, but elliptical. So heliocentric theory was closer to the true structure of the world than geocentric theory, yet it fit the data worse. Here’s the powerful message: sometimes, to get closer to the truth, you first have to move away from what best fits the data. And this is why gradient descent — the basic optimisation procedure underlying modern AI models — is fundamentally limited: it pushes models to better fit the data they see. But fitting data is not the same thing as discovering truth. If medieval astronomers had had LLMs, we would still believe that Mars orbits the Earth along some crazy path.


The fine-tuning argument for the existence of God is really bad. Watch physicist @seanmcarroll debunk this incredibly weak argument here: youtu.be/gRp0ent1Z0A?is…


🚨 Simulation Theory: The Double Slit Experiment proves particles act like waves until observed then they snap into particles. What if our reality only "renders" when we're looking, just like a video game optimizing resources? Check out this episode from The Why Files breaking it down, tying it to Simulation Theory. Are we in a sim? This could be the key to unlocking the true nature of existence! The Why Files video did a great job on explaining the Double Slit Experiment & Simulation Theory What do YOU think—real or rendered? Drop your thoughts below!


The 2024 Nobel Prize in physics went to a computer scientist. Now, in turn, the 2025 Turing Award was given to a physicist!



I had dinner once with a top physicist and a top computer scientist and asked what they thought the probability was that we were in a simulation. They answered simultaneously at 0% and 100% respectively. It was like a double-slit experiment, but with humans.
