Over on my blog at https://terrytao.wordpress.com/2024/04/19/two-announcements-ai-for-math-resources-and-erdosproblems-com/ , I announced Thomas Bloom's call for assistance on his erdosproblems.com site, as well as @TaliaRinger 's AI for math resource list that I posted about here recently.

Here’s what parenting can look like.

When I told my dad I was trans, my dad’s response was, “Oh! I can send you jewelry now!” (He was retired and made jewelry as a hobby).

Two days latter, I had a letter in the mail addressed to Joelle, the first time “Joelle” ever got mail, with a necklace in it. Later he made me this one. He told me, “I hope I got the colors right, I looked it up online.”

You don’t have to mourn a child transitioning. You can be the first to do so many affirming things.

"Do the explanations get more disorganised the further you get into the book?"

No, but the reader will probably feel that way.

Cellebrite Premium documentation we published in May and which recently received a lot of media coverage was from April 2024. Someone has shared a newer version of the iOS table indicating Cellebrite caught up to iOS 17.5.1 or higher along with the iPhone 15 for the OS exploits.

The “Science in Fiction” podcast had me on after Avi Loeb. So, you can bet that first contact scenarios, Fermi Paradox stuff and plausible types of Alien Probes in the Solar System all came up.

Hidden in deep darkness, there may be a trillion sunless planets wandering our galaxy -- including vast numbers of Earth-size worlds exiled from their homes.

The discovery of these "rogue planets" is one of most fun stories I've covered. Read it here:

hey yall, here's a #science thread!

One of the larger excitements of my past couple months is finally getting this paper out -- it's up on arXiv tonight and accepted to ApJL (with an AAS Nova highlight on the way)

This paper is trying to answer the question of how many really big black holes are in our corner of the universe and the consequence of that number.

We think that our work substantially refines the census of black holes more than about a billion times the mass of the sun, which places constraints on the evolution of massive galaxies over the past couple billion years and furthers our understanding of the cosmic gravitational wave background

In this thread I'll tell ya how we did it! Let's dive in!

Did you know that all #Hubble and #JWST images (and most things produced by @spacetelescope) are in the public domain?

That means you can do whatever you want with them (as long as it's legal), including charging admission to see your exhibit of T-shirts with JWST images printed on them, to help fund your Hubble-inspired tattoo.

Travelling by sleeper train beats travelling by plane. Hands down.

I’m travelling in a small hotel room with a view. It almost feels as soothing as sleeping in a boat. I got to the train by foot and I’ll arrive in the city centre.

Compare that to a cramped seat in a crowded plane and traffic jam before and after the trip.

Trains are the future of transportation.

Building on a comment I saw on TikTok, it is quite remarkable that Joe Biden showed us that he was the right man for the job by deciding to step down from the campaign and put his ego aside for the good of the country.

Something big happened this weekend. Everyone is talking about it, wondering what the implications will be.

That's right: I finished writing my new book "What is Entropy?" It's just 120 pages long. It has lots of short sections, mostly one page each, each based on a tweet. This is just a draft, and I'm still fixing lots of typos and other mistakes. So grab a copy - and if you catch errors, please let me know, either here or on my blog!

It is not a pop book: it's an introduction that assumes you know calculus. But it's about a lot of big, bold concepts, and I try to really get to the bottom of them:

• information
• Shannon entropy and Gibbs entropy
• the principle of maximum entropy
• the Boltzmann distribution
• temperature and coolness
• the relation between entropy, expected energy and temperature
• the equipartition theorem
• the partition function
• the relation between entropy, free energy and expected energy
• the entropy of a classical harmonic oscillator
• the entropy of a classical particle in a box
• the entropy of a classical ideal gas

I learned a lot by trying to explain in words what people often say only in equations.
