We want to support the mathematics community in turning progress in AI into deeper human understanding and new discoveries. To support that goal, we are contributing $5 million to a new Simons Foundation initiative to help mathematicians examine, understand, and build on results produced by AI, including the results we recently published.

The funding, managed and awarded by the @SimonsFdn will support workshops, conferences, and special programs. We will also provide access to our models and computing resources to Simons Foundation-supported researchers.

Bryan Johnson himself said cerebrolysin is the best thing he has ever done for mental clarity.

This is the most biologically measured and studied person that has ever existed saying this.

Cerebrolysin on top.

~15 years ago @DavidDeutschOxf wrote https://t.co/GRRImyatAf and said "Expecting to create an AGI without first understanding in detail how it works is like expecting skyscrapers to learn to fly if we build them tall enough." I turned that into a parable: https://t.co/alEkVadqm0

@dchackethal @ToKTeacher is ''critical attitude'' a requirement for consciousness?

“the ability to notice problems, question one’s own assumptions, and correct one’s errors.”

[Brett Hall @ToKTeacher]

They’re so smart they destroy themselves?

I guess it’s the exact opposite!

how to sleep through the night:
-2 tablespoons honey + pinch of salt before bed (this was critical for me)
-10 min sunlight first thing in am (no sunglasses!)
-no blue light, no flickering light 2 hours before bed (no phones, no LED lights etc, red light in house etc.)
-majority of fluids in first 10 hours of the day, minimize after that
-adequate calories during the day (from high quality foods) + reasonable macros (0.8 g protein/lb goal body weight, ~25-30%+ fat cals, carbohydrates based on activity level- at least 150g daily)
-magnesium prior to sleep.

Worth considering

[BasedBiohacker @BasedBiohacker]

most people think circadian rhythm is just about sleep, but in reality it governs:

- testosterone and growth hormone release timing

- melatonin and antioxidant defense

- immune cell activity and inflammatory response

- neurotransmitter synthesis

- DNA repair mechanisms (this peaks at night)

- cortisol production and stress response curve

- insulin sensitivity and glucose metabolism

- blood pressure fluctuation throughout the day

- body temperature regulation

- gut motility and digestive enzyme release

- liver detoxification cycles

- cell division timing (disruption = cancer risk btw)

- cognitive performance windows and memory consolidation

- mood regulation, emotional resilience

EVERY chronic disease has a circadian component. metabolism, immunity, cognition, hormones - all of it follows circadian patterns.

when the clock breaks, everything downstream fucking disintegrates with it.

the clock lives in your pineal gland.

epitalon is the only compound with documented evidence of directly restoring pineal function, reactivating melatonin synthesis machinery, and resetting clock gene expression at a molecular level. not exogenous melatonin.

when you supplement epitalon, you're not just "fixing sleep", you're hitting all the points i described above.

and that's part of why the kiev study resulted in a 40% mortality reduction. your local pharma rep won't mention that though. not medical advice...

3-6mg/ day for at least 30 days this winter. effects persists after you quit dosing for a good while.

the epitalon i use is linked below (or you can pin - more links for this in website linked in profile)

epitalon = circadion = AEDG, btw.

BASED gives you a 10% discount on all of the below.

just solved the hypersurface case of Chen’s conjecture:

"Every biharmonic hypersurface in Euclidean space is minimal."

it's been proved in E³,…, E⁶, but resisted full generalization for 41 years. but with some help from gpt-6 astra, here’s a proof in every dimension :)

Ten years ago, I offered students a free £50 in class and asked who wanted it. Many students put their hands up, but only a couple were bold enough to come forward and try to take it (even though I made clear it was freely available, and not stealing). This was a social experiment to encourage students to take every opportunity and be proactive, even if it involves discomfort and going against the grain.

The £50 went to a student, Laura, who kindly tried to give it back to me after class, but I insisted she'd earned it. I was delighted to see Laura again on Friday when giving a talk to the @LBS Alumni Council. It's no surprise that the same qualities she exhibited 10 years ago are also evident in her willingness to step forward and serve her alumni community on the Council.

Interesting. I think this is true. Or contains a lot of truth.

Knowledge, bah! Who needs more knowledge? It is well known for having <gasp> Side-Effects. Whereas ignorance never hurt anyone!

You don't need religion to refute Dawkins's attack on religion. You only need a cow.

@RichardDawkins : “You could possibly persuade me that there was some kind of physical, mathematical genius who created everything, the expanding universe, devised quantum theory, relativity, and all that. But that is radically and fundamentally incompatible with the sort of God who cares about sin, the sort of God who cares about what you do with your genitals. A God who's grand enough to make the universe is not going to give a tuppenny cuss about what you're thinking about and your sins. If I were going to respect a God, it would be the sort of God that Carl Sagan might have worshipped, not the sort of medieval God who fusses about sin. I keep coming back to this word petty, and I stand by it.”

Petty? Listen instead to @DavidDeutschOxf : “Humans, people and knowledge are not only objectively significant: they are by far the most significant phenomena in nature.”

We have walked on the moon, wiped smallpox off the earth, and some of us (not me!) have a working model of a quasar in their heads. And unlike the rest of the universe, we're only getting started. The stars, quasars, planets will continue to be what they have always been: static, repetitive, bland. Biology will continue to evolve at glacial speed. But we can progress at breakneck speed if, on this question, we listen more to Deutsch than to Dawkins.

We are not defined by our size or energy, and we should rejoice that we're in a very large place. As Deutsch says: "Feeling insignificant because the universe is large has exactly the same logic as feeling inadequate for not being a cow. Or a herd of cows. The universe is not there to overwhelm us; it is our home, and our resource. The bigger the better.”

This is one of the surprising parallels between the Deutschian and Christian worldviews. Both are, in 2026, equally countercultural in their correct appraisal of the significance of humanity.
