I am so happy today for Francis Halzen and for the IceCube collaboration. The Nobel Prize for Francis, for IceCube, and for high-energy neutrino astronomy is very special for me, both scientifically and personally.

This man made more money than any trader alive and he never took a single finance class. Jim Simons was a geometry professor. Then he built a fund that returned 66% a year for 30 years and became the highest paid mathematician who ever lived. Renaissance still pays more than Jane Street or Citadel for one reason: a tiny real edge, times enormous scale, is an enormous amount of money. The market does not pay you for knowledge. Knowledge is free. It pays you for being right about how sure you are. In this talk he lays out the five principles that took him from a fired codebreaker to the best track record in market history. The one about hiring beats every trading tip you have ever read.

Twenty-five years after the Sept. 11 attacks, the Brown community gathered at Patriots Court to remember the lives lost and honor the six Brown alumni who died on 9/11. The campus memorial bears their names and ensures their memories endure.buff.ly/8PWAnJE

MIT published a brutally honest report on what AI is doing to students. A committee of professors and students spent five months studying how AI changed learning on campus, and the findings read like a warning to every university on the planet. Study groups are disappearing. Office hours are emptying out. Problem sets and take-home exams no longer prove anything, because AI can produce credible solutions to almost any written assignment in the undergraduate curriculum. Students who lean on chatbots lose mastery and confidence, and some slip into what the report calls cognitive surrender, reaching for AI at the first hint of struggle. The numbers are rough. 46 percent of surveyed MIT undergrads use LLMs daily. 90 percent worry about their own overreliance. Undergrads who feel AI makes them replaceable now outnumber those who feel it makes them capable. The committee's answer surprised me. They refused to fight AI with surveillance. The report calls AI detectors unreliable, says lockdown browsers feel like spying, and warns that policing students builds a classroom atmosphere of mutual distrust. Instead, MIT wants to rebuild education around the things AI can't replace. That means oral exams, semester portfolios, in-person project work, and a required social component in every subject. The report even floats the idea of rethinking grades entirely, since without a GPA to optimize, much of the incentive to cheat with AI evaporates. The committee warns professors against replacing undergrad research assistants with AI agents just because they're cheaper, because a university exists to grow people, not output. The most famous tech school on earth admitted the machines broke its way of teaching. Its answer is more humans, not more software.

What are the backgrounds for our event of interest LZ230616, and why can't they currently explain it? 🤔 A thread: 🧵 [Images from the TeVPA talk, available on our website lz.lbl.gov/] #darkmatter #LZ230616

Governor. @GovDanMcKee I’m sitting, queuing in a long traffic tail back on the half of Washington Bridge that is still standing. Nothing actually happening with the construction of the other half. (I have plenty of time to watch.) Why is this managed so badly?

Our new results are out! We have observed a single nuclear recoil in our detector that we find difficult to explain with our background model. Could it be a hint of dark matter? It’s far too early to say, but it’s certainly intriguing! #darkmatter

The LZ experiment has observed a particle interaction that could be interpreted as a signal from WIMPs, a #DarkMatter candidate — but researchers need more data to know for sure. @lzdarkmatter @BerkeleyLabPSA newscenter.lbl.gov/2026/09/0…

Could this unexpected signal be our first detection of dark matter? The LUX-ZEPLIN experiment, world-leading dark matter detector, has observed a particle interaction that is the most compelling hint of dark matter reported by the experiment to date: stanford.io/4gvEi4D

Excellent new EFT (Effective Field Theory) dark matter analysis from our experiment - and we have over 3x data now for a follow up analysis - more details from the Collaboration at lz.lbl.gov

After reviews of 2025 campus shooting, Brown releases action plan to further strengthen preparedness. While external review found it “highly unlikely” the shooting could have been prevented, it stresses the need to continue to bolster safety and security for the future.

Every college syllabus should include these graphs. Use AI for homework, you will get it done faster and get a higher grade, and then get crushed on the exam.
