Adam Brown (@A_G_I_Joe) is back!
General relativity is said to be the most beautiful idea the human mind has ever produced.
Most of us will never get to fully appreciate its elegance by taking the 20-lecture graduate course Adam taught on it at Stanford.
But in the video below, Adam distills the key idea at its heart so clearly and compellingly that even I could keep up lol.
At the core of general relativity, Einstein is trying to figure out the principle behind a particular coincidence: that the mass that resists acceleration and the mass that gravity pulls on just happen to be exactly the same. Adam then leads us through the path of insight which Einstein called his “happiest thought.”
Then Adam lectures on black holes. First, by showing how even under special relativity you could create a perpetual motion machine if black holes weren't truly black. And then, by explaining why the observations of an infalling observer and a distant bystander to the black hole would be so radically different
Adam leads Blueshift, the team at Google DeepMind cracking science and reasoning.
Which gave us the opportunity to discuss at the very end how close we are to AIs that could rediscover general relativity from scratch. Stay till the close for some philosophy of science.
0:00:00 – The coincidence that led Einstein to general relativity
0:16:42 – Gravity is a consequence of curved spacetime, not a force
0:31:46 – Why black holes prevent unlimited energy extraction
0:47:12 – Black holes are the ultimate power plants
1:13:50 – What falling into a black hole would actually feel like
1:18:51 – The three ways we know black holes are real
1:24:21 – The first time we saw gravity bend light
1:29:33 – How far can AI get without experimental evidence?
Look up Dwarkesh Podcast on YouTube/Spotify to watch. Enjoy!

fun piece of trivia: I interned for @JMRothberg who created the ultrasound-on-chip tech behind the scanner
great work @DavidSHolz + team!
play with the model below (thx Devin for carrying)

AI DETECTOR COSTS STUDENT $45,000 SCHOLARSHIP
Is this where we’re headed? Universities and companies treating AI tools as the law?
The board refused to even look at his six months of edit history. Their reason? The software is “highly calibrated and accurate.”
I want to know. How much the robot is gonna be costing + the energy consumption ; and we’ll know if this version is true worth to have in manufacturing ( i doubt it for now, very early comparing cost > revenue )
🇺🇸 Figure says its robots have now sorted more than 100K packages while working 80+ hour shifts in “nonstop autonomous ops.”
Built different. Literally.
