I can believe Grok 4 is routinely nailing Physics Olympiad style problems, and yet it seems to still be missing the core of insight which is so critical to physics. I have asked it three of my standard tough problems, where the answer is much less important than the chain of.

Link: . I regard his primers on Russian and Latin to be about the best thing I've ever read on those subjects. The Latin, in particular, is absolutely essential now we are decoding the scrolls (@scrollprize) so get started now, to sharpen yourself.

I have recently archived the works of my brilliant, patient, and long suffering mentor in Latin, Russian, and other stuff. While he is still very much alive and sharp and healthy, for a man in his late 80s, I was concerned that his insights were hidden in various out-of-print

Imagine if we made it easier for Europeans to start companies. Their founder types are literally doing this instead of building trillion dollar companies.

You're not going to like the answer, but it rounds to wire heading. Your dating flow looks like that because your dating app is selling engagement to advertisers not matches to you (which is much less valuable to them) and you're mostly interacting with fake profiles invented.

There has to be a connection that explains why both dating and looking for a job now produces charts like those below.

I flew through LAX today so took the rare Westside opportunity to catch up with @andrewmccalip at @VardaSpace and @isaiah_p_taylor (and his lovely family!) at @valaratomics. We're building the future in Los Angeles and it's going to be awesome!.

Coming around to the view that, if in doubt, the best way to learn very rare meta skills, is to tackle them in a series of borderline crazy ambitious projects. There's no reading list that will give you this knowledge. You just have to do things, after that you'll have the.

This is typical degrowth propaganda. Growing food requires water. I like cheap food. It is not a moral failing to grow copious quantities of cheap food even if it occurs out of sight of a Starbucks.

California would have plenty of fresh, quality water if we would just rationalize agriculture water policy. Instead, we incentivize growing thirsty crops in the desert which we export to other deserts. ONE COUPLE (the Resnicks) use as much water as the entire city of Los Angeles.

No part of California is more than 350 miles from the ocean, a limitless supply of water. Every time an official wastes their life advising water conservation, or you drive past 100 miles of broke, fallow farms near the I5, or a city burns to the ground, remember. Water.

California should be the most agriculturally productive place on earth. We can make energy abundant and desalinate the ocean. Desal tech has advanced considerably, as has solar and nuclear. And the brine can be a feedstock for lithium, magnesium, and other critical minerals.

Maybe these extra solar objects are the remains of probes other civilizations used to examine older extra solar objects.

Project Lyra explores the possibility of sending a spacecraft to chase 'Oumuamua using an Earth gravity assist to reach Jupiter, which robs the craft of almost all its speed, causing it to drop to the Sun for an Oberth maneuver. Thanks @hibberdadam994 for the trajectory data!

Today my six year old said "If the RL-10 has higher specific impulse than the Raptor why doesn't SpaceX use it for Starship?". Then we discussed fuel density and the square cube effect and the cost of tanks. Fathers, don't let your sons Isp-max naรฏvely.
