Let me tell you a little bit about my second book, and how it relates to my first book. 1/ worldscientific.com/worldsci…

If your first email ended in @ yahoo, @hotmail, or @msn... you have seniority on the internet.

Welcome news. Planetary protection policy was increasingly being driven by the priorities of wackos.
Replying to @ID_AA_Carmack
I can assure you we have already been working on revisions to the planetary protection policies to bring them back in line with the common-sense principles originally established by COSPAR in the early days of planetary exploration and later reflected in Article IX of the Outer Space Treaty. We are needlessly adding extreme cost and time to robotic missions to Mars when the overarching goal is to send astronauts there as quickly and safely as possible.

Still wrapping my mind around the fact that in quantum mechanics, all electrons are identical and no one knows which is which

Lately I've been thinking a lot about mathematicians What does it feel like to be surpassed by AI? What does it do to your sense of self? Your beliefs about your work? About the future? So we found some of the world's best mathematicians and asked them A chronicle of a moment in history:

The destruction of science at NASA continues.
Today, NASA announced PRIMA, a new space telescope that will explore long-standing mysteries around the formation of planets, stars, black holes, and even how water on Earth came to be. go.nasa.gov/3TgGh3W

"White empiricism" will always hold a special place in my heart.
The best Woke 1 neologism was "misogynoir."

We're next.
Replying to @tszzl
and we’re very much there now. probably weeks or months away from tremendous progress on mathematical physics (and then slowly other kinds of theoretical physics) the way we see in pure maths right now

A reminder that style guides have become a vehicle for the advancement of political agendas.
Artificial intelligence systems do not think, feel, want or understand. Avoid language that gives them human characteristics. This is called anthropomorphizing, when we ascribe human traits, emotions or behaviors to non-human things, such as animals or inanimate objects. Instead, explain what a system does, how well it performs, who built it and who could be affected by it. apnews.com/article/openai-sa…

This book is worth whatever you have to pay for it.
Today's question: is there an international, softcover edition of this book in existence, published in India or anywhere in other Asian countries ? Someone told me there are, published on cheaper quality paper... not sure if that's true. I have never seen it.

I actually miss cycling in Manhattan. When you're on, it's zen. I used to ride 6th Avenue purely for the sport.

See the dashed lines in the bike lane? That means cyclists need to allow right-turning vehicles to merge.

Correct move here is to slow down behind the truck, take the lane, and pass on the left.

Dartmouth student newspaper: "An investigation ... of academic articles and opinion pieces published by Provost Santiago Schnell in 2026 found a median 'AI-written' text percentage of 96%." His statement to the paper about this story "was itself '100% AI-written,'" per @Pangram.
