If you do functional programming (like in Wolfram Language) you've probably used lots of pure functions, or lambdas. But what are lambdas like in the wild? Things I'm doing in CS, bio and ML converged to make me curious to find out... writings.stephenwolfram.com/2025/09/the-...

Trying to understand yet another strange collection of creatures in the computational universe....

I've been getting mail with unsolicited "theories of physics" for 50 (!) years. What can one do with all that enthusiasm and energy? Maybe now I have an idea... writings.stephenwolfram.com/2025/08/i-ha...

Launching Version 14.3 of Wolfram Language & Mathematica. It's a version with a particularly large number of very long-awaited features (including ones planned for 38(!) years) ... that we finally figured out how to deliver! 🎁 writings.stephenwolfram.com/2025/08/new-...

Nice pictures I happened to just get and thought I should share...

Wow! Look at what high school students just did in 2 weeks #WithWolfram at the Wolfram High School Summer Research Program. (And, yes, in "extreme professoring mode" I tried to get to know all 75 students and suggest projects that would be great fits for each of them...)

Just finished three exciting weeks of our (23rd!) annual Wolfram Summer School ... with lots of interesting projects done ... www.wolframcloud.com/obj/microsit...

I've often wondered what it'd be like if we had bigger brains. It's not easy to imagine what minds beyond ours might be like ... but I just gave it a try ... writings.stephenwolfram.com/2025/05/what...

Today is the birthday of A New Kind of Science. What a huge project that was (10+ years, etc.)! I'm still amazed it actually got done. At the 20th anniversary I told some of the behind-the-scenes story... writings.stephenwolfram.com/2022/05/the-...

From the point of view of science I've never been too excited about the Game of Life. But now I realize that what's really exciting about it is what it tells us about what we can call metaengineering... writings.stephenwolfram.com/2025/03/what...

#PiDay served with a slice of off the cuff history from @stephenwolfram.bsky.social youtu.be/fvbDvPbH00w?...

I'm excited to share yet another (unexpected) application of my recent science: a computational formalization for foundations of medicine. (Why is medicine hard? Are there a finite number of diseases? ...) writings.stephenwolfram.com/2025/02/towa...

A quarter century ago this minute ... a century-old problem was solved when out of my Mathematica program popped the shortest possible axiom system for logic ... though to this day nobody understands the computer-generated proof...

Launching Version 14.2 of Wolfram Language & Mathematica: big data meets computation & AI... writings.stephenwolfram.com/2025/01/laun...

My father would have been 100 years old today ... which really helps humanize for me what a century means...

Just wrapped this year's Wolfram Science Winter School. Lots of ruliological intuition building, mixed with mathematical physics and some computational philosophy... education.wolfram.com/programs/

Formalized math: meet computational irreducibility. A simple (if surprising) theorem. An automated proof nobody seems able to understand. A tale of adventure in the wilds of metamathematical space... #MathSky writings.stephenwolfram.com/2025/01/who-...

An unexpected little ruliological discovery just made live a few minutes ago during my inaugural "Q&A for Scientists" livestream... youtu.be/9_t1ysElDL8

Useful to the point of being revolutionary: introducing Wolfram Notebook Assistant! writings.stephenwolfram.com/2024/12/usef...

Biological evolution is a fundamentally computational phenomenon! Just posted lots of new results (and surprises) from my minimal model of adaptive evolution... writings.stephenwolfram.com/2024/12/foun...

Born 65 years ago this minute. Happy to say the last five years have been my all-time most productive (so far)... writings.stephenwolfram.com/2024/08/five...

Taller and broader. Announcing Version 14.1 of Wolfram Language & Mathematica ... available today for desktop, cloud, etc. The same core mission and core ideas. But 36 years later ... check out what it's turned into! writings.stephenwolfram.com/2024/07/yet-...

How do the LLMs compare? Leveraging our "code grading" tech to introduce weekly computationally grounded LLM benchmarking... www.wolfram.com/llm-benchmar...

Today my all-time favorite science discovery is 40 yrs old! My June 1, 1984 diary told me to "take pict." of "R30" on a 9 pm flight to London ... which is when I finally realized (2 yrs after first generating it) what a big deal rule 30 is...

Foundations of physics, mathematics, computing ... now biology! The ruliad is on a roll.... (Up next: machine learning ?) writings.stephenwolfram.com/all-by-date/

They're the ruliad champions! The "busy beavers" of the (symmetric 3-color) cellular automaton world ... the rules that live longest before dying out... [How does that rule "know" to die out after 2194 steps??] writings.stephenwolfram.com/2024/05/why-...

Biological evolution. Machine learning. Why do adaptive processes actually work? Finally found what seems like a good minimal model for biological evolution.... writings.stephenwolfram.com/2024/05/why-...

Found some new friends today in the computational universe:

In case you missed today's eclipse, there are always more to come (at least for the next few hundred million years). Here's where the total eclipses will be for the next 100 years: writings.stephenwolfram.com/2024/03/comp...

The eclipse from first principles: using the Wolfram Language (and its SolarEclipse[] function) to compute eclipses (and to analyze a couple of the eclipses I've seen) writings.stephenwolfram.com/2024/03/comp...

How do we know precisely when the April 8 North American eclipse will happen? Well, it's a rather fascinating tale of science and computation---spanning more than 2000 years, and featuring many of the all-time greats of mathematics and physics... writings.stephenwolfram.com/2024/03/when...

I've been wondering: can AI solve science? I just did some analysis... writings.stephenwolfram.com/2024/03/can-...

AI, AI, what can you do?

ARPublish[ ] from Wolfram Language to the Moon... writings.stephenwolfram.com/2023/06/llm-...

Say it with Wolfram Language: a card deck's worth of traditional-tweet-length code nuggets that make a world of different images, some surprising, some artistic, some mysterious .... now available as Wolfram Code Cards www.wolframcloud.com/obj/microsit...

How do we know (exactly) when and where an eclipse (like the one coming up on April 8) will happen? I just published a small book that tells the story: an inspiring tale of science, mathematics and computation spanning more than two thousand years... www.amazon.com/Predicting-E...

Just wrapped our 2024 Wolfram Winter School. I assumed in 11 days there'd only be time for studying ... but actually some students managed to do projects in physics, philosophy & more wolfr.am/1jnsTRS5I

Hello, Bluesky. What should I post here? Maybe about the livestreams I do every day or two? Maybe about ongoing work I'm doing? Events I'm going to? Let me know what you think...
