I created a Claude Code skill that scours every major indexing service on the web to find the source or PDF for scientific papers, so that when you cite a paper, the claims you make around the citation are grounded in the actual content of the cited paper: github.com/lukehutch/allpape…

After a year of intensive and difficult work, I completed and submitted two physics papers that identify the origin of all force laws (other than the weak and strong force), including gravity and inertia. This also identifies the origin of the equivalence principle. A core finding: time dilation creates gravity, gravity does not create time dilation. The central identity identified in the first paper, F = −ħ∇ω (the force experienced by a particle is linearly proportional to the gradient in the frequency of the particle's wave function) unifies general relativity (∇ω), quantum mechanics (ħ) and classical mechanics (F), without requiring the quantization of gravity or invoking a graviton. In the second paper, I reformulated the Dirac equation (the relativistic version of the Shrödinger equation for the wave function of a particle) into quaternionic form, and was able to show that all force laws other than the strong and weak force can be directly obtained from the wave function, in combination with the force-frequency identity of the first paper.

Replying to @LH @jon_barron
The numerical trick is rewriting in log space with softplus, expm1 and log1p. For Softmax Collapse this keeps the tiny e^{-m} in the numerator (via softplus on the margin excluding the max) so it never rounds away when added to 1. For Softmax Cancellation it forms q-p from logit deltas via expm1/log1p, avoiding subtraction of near-equal probabilities. Gradients stay accurate and sum to zero past precision cliffs, letting weight decay balance cleanly at m≈log(1/ε) without vanishing or slingshots.

Neural networks' trained states are about to get much, much closer to optimal.
Hi all, I have a new result I'm excited to share. It turns out that *all existing implementations* of softmax and cross-entropy (that's JAX, PyTorch, textbooks, etc) have a subtle bug --- two bugs, actually. A simple rewrite fixes both, and eliminates "slingshots" when grokking:

what if you could pass a TypeScript type to JSON.parse and it validates the input at runtime?

PS if anyone has arXiv endorsement rights (especially for gr-qc), I would really appreciate an endorsement so that I can put the preprints on arXiv: arxiv.org/auth/endorse?x=M4J…

I paid for an X subscription so that I could edit tweets instead of copying, deleting, and then pasting into a new tweet so I can edit it, like a caveman. And now I find out that only posts can be edited, not comments. @elonmusk please fix this, it's ridiculous.

**You need to watch Zelenskyy's interview with Steven Bartlett.** Sitting in front of the camera is an utterly exhausted, at times visibly broken man who has spent almost five years personally managing a war, making critical decisions day and night. From the very first minutes, you can see just how drained he is. When asked the routine question, "How are you?" he replies that he barely sleeps because he spends his nights in military group chats, moving the last remaining air defense systems from one region to another. Two stories are particularly heartbreaking. The first is about a missile that struck a children's playground within seconds, while parents watched from their apartment windows as their children were torn apart. The second is about presenting posthumous military awards to the families of fallen soldiers: "You present an award to a father, feel his strong hand, and then he quietly asks, 'Can we hug?' At that moment, I simply cease to exist inside. These people are gone. They will never be the same again." When the host tries to take him back into his past, showing old photographs from Kryvyi Rih, his student comedy performances, his voice acting as Paddington Bear, and scenes from *Servant of the People*, Zelenskyy looks at them with detachment, almost as though he is watching someone else's life. He also recalls February 2022 without any attempt to portray himself as a hero. He says that for the first 20 days, he simply ran from office to office on adrenaline, calling everyone he could and trying to organize deliveries of water and food to Kyiv. Fear and the full realization of what had happened only caught up with him three weeks later, when Bucha was liberated and mass graves containing hundreds of murdered civilians were discovered. Using Bucha as an example, he explains why advice from outsiders to simply negotiate a quick deal causes him such deep frustration: "Imagine that in the United States or Britain, a mass grave is discovered containing 500 tortured people with their hands tied. How could you simply forgive everything after that?" The rest of the conversation revolves around the deadlock in which Ukrainians, and indeed everyone involved, now find themselves. Zelenskyy explains the causes of the war in simple terms: Moscow is trying to forcibly rebuild the Soviet empire because Ukraine's integration into Europe would finally bury that project. But when the conversation turns to the present, there is unmistakable bitterness in his words. Almost one-fifth of Ukraine's territory is occupied. The east is under relentless bombardment. Cities are left without electricity. People are dying every single day. Meanwhile, every discussion about a ceasefire runs into the same demand: Kyiv must withdraw even farther from its fortified positions, without any guarantees that Russia will not launch another offensive a year later. Toward the end, the conversation turns to Trump and Ukrainian strikes on Russian oil facilities. Trump publicly reprimands Zelenskyy over attacks on Russian refineries because he fears rising diesel prices for American farmers ahead of the elections. And this is where you can see just how deeply that approach affects Zelenskyy. His country is burning. Moscow has rejected his proposal for a mutual halt to attacks on energy infrastructure. Patriot missiles paid for by Europe are being redirected by the Americans to the Middle East. And somehow, Zelenskyy is the one being blamed for fuel prices in the United States. The entire interview leaves you with a profoundly bleak feeling. Here is a man trapped between the daily deaths of people in his own country and the pragmatic bargaining of allies who have their own elections, their own interests, and their own political calculations. And yet, he can no longer step away from this responsibility. **Watch it.**

Take a photo of your mail-in ballot and then upload it to Claude or Gemini with research mode enabled, and steal my prompt: Analyze this ballot and give me a very detailed analysis of the integrity or lack thereof of each candidate, focusing on past actions, platform promises made, kept, or broken, allegiances, political alignment, what the candidate has stood for or against, any known or alleged past misconduct, issues of morality or integrity, whom the candidate has helped or hurt, and who seems to be behind each candidate (billionaires, PACs, lobbying groups, etc. -- research who has funded each candidate in the past). For each ballot choice, give me an objective summary of what interests I would be supporting and which interests I would be hindering or harming by checking the box.

So I hate to give Elon even one cent, but here we are, I'm now paying for X. I really hate it when social media platforms hold basic functionality (like editing a post, or being able to post more than a few lines) hostage to a subscription. Find some actual added-value reason to convince me to pay, don't force me to pay because I need basic functionality.

3% of “critical” software security bugs, in all of recorded history, have been found in the last month. This is on pace to find another ~100,000 bugs this year alone, adding ~26% more vulnerabilities to the all time total Do you realize how fucking insane that is?
