some recent work

@CKalitin This is very cool. I wrote some aerocapture/entry sims to calculate how fast Starship could survive a Mars aerocapture - some of those in here: https://t.co/JAYPc4mh5f
Interested to see if you come up with similar results

[Jack Kingdon @jdysn4]

@CKalitin yea, I hadn't seen that BFR simulation before, that is cool. Did not expect blunt body estimates could get close to that sim.
You should try your code on Earth and try to fit to the IFTs, and Starship should have quite a bit higher L/D than a blunt body.

@CJHandmer What volume of water is this?

@s8mb Have you guys considered going a WIP article on negative income tax?

[Jack Kingdon @jdysn4]

@bzogrammer I'd have thought that the dimensionality of the 'inputs to a Cat' quite low? Why do those inputs end up represented in high dimensions?

@Robotbeat Easiest win is to make sure that the first person to walk on Mars is a woman

@Robotbeat Musk is gonna have to embrace DEI (or do something cultural genius) to ratio issues on Mars

@zetalyrae @DanielSacilott6 Don't you feel that you get ~(5+)x value out of a textbook if you do problems?

People like standing in long lines because it gives them purpose without responsibility

@ChrissGPT @aphysicist Maybe even recursively self fix due to it being AGI?

Suspicious graph here

[Anthropic @AnthropicAI]

The speedup isn’t just in volume. On open-ended coding problems where answers are unclear, Claude’s success rate is now 76%—a 50 point jump in just 6 months.

Many engineers also say Claude’s code quality is now on par with human code; we expect it to be better within the year.

@Robotbeat Why is it so hard to work out if both fusion & QC companies are serious even with a physics background? What benchmarks are there that are similar to rockets, eg do they have a working engine?

[Visa is doing marketing consults (see pinned!) @visakanv]

@gbrew24 Has this quantitatively impacted Chinese industry?

[Michael A. Arouet @MichaelAArouet]

So many people claim that the EU doesn’t drive global innovation anymore. What do you say now?

[Gregory Brew @gbrew24]

I think we are generally sleeping on the fact that China ramped imports up by 1-2 million bpd for over a year, and then slashed them by 6 million bpd in a few months, all through direct market interventions.

If the closure of the strait of Hormuz is the biggest deliberate market manipulation in history, what has happened with Chinese imports ranks as No. 2.

@Noahpinion I think scifi has been pretty neutral as to whether the AI was given emotions during programming or whether it was imagined to have emotions by humans post programming
