Dirac couldn't get hired as an electrical engineer. A 19-year-old with a Bristol degree in 1921, during a post-war depression that had no use for him. So he stayed at Bristol and studied math for free because there was nothing else to do.
Two years later he got a fellowship to Cambridge. His advisor, Ralph Fowler, handed him proofs of an unpublished Heisenberg paper in August 1925. Dirac read it and realized the math resembled Poisson brackets from classical mechanics. Within months he had built an entirely new mathematical framework for quantum theory.
He published 11 papers before submitting his thesis. Eleven. Most PhD students struggle to publish one. Dirac had a body of work that constituted an entire theoretical foundation, and he still needed to package it into a dissertation to satisfy the degree requirements.
The thesis title tells you everything about the confidence level. When you title your PhD "Quantum Mechanics" at age 23, you are either delusional or correct. Dirac was correct. It was the first PhD thesis ever written on the subject.
Two years after that he wrote the Dirac equation, unifying special relativity with quantum mechanics and predicting antimatter before anyone had observed it. By 1932 he held the Lucasian Professorship of Mathematics at Cambridge. The same chair Isaac Newton held. He was 30.
Nobel Prize at 31. The youngest physics laureate at the time.
The entire arc from unemployable engineer to owning Newton's chair took 11 years. The field he named his thesis after is now the operating system of modern physics.
📚 À San Antonio, les bibliothèques publiques de la ville ont lancé il y a quelques jours un programme "Read like Wemby", qui permet aux habitants de la ville d'emprunter les favoris de Wembanyama en matière de Fantasy/Science-fiction.
L'Alien emmène un livre partout où il joue, et a plusieurs fois expliqué tout le temps lire avant un match.
Déjà 160 livres issus de la liste ont été empruntés, selon @TheAthletic qui a écrit un article sur le sujet. Une goutte d'eau par rapport aux nombres d'habitants de la ville (1 450 000)...
...Mais une donnée intéressante quand le média souligne que 40% des américains n'ont pas touché à un bouquin depuis 1 an au minimum.
We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity.
This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.
@Chessiro_@chesscom Hey @Chessiro_, I’d like to understand how can my position go from « White clearly better » to « Black clearly better » by playing the top computer move ? The evaluation goes crazy even when I am playing the best moves. That’s a pitty as I really like your concept… Thanks.
Bethlehem, the birthplace of Jesus, was over 80% Christian under Israeli control.
In 1995, the Palestinian Authority took over.
After 30 years, Bethlehem is now less than 10% Christian.
This is what ethnic cleansing looks like.
@SohanL94@MGN_75 Regarde l’évolution de la population chrétienne dans les pays du moyen orient qu’on rigole. 320 millions de chrétiens persécutés c’est pas en Israël tout comme le génocide arménien
