I think his main contribution was some work on granular materials that had useful industrial applications.

Unfortunately I am getting to the point where if I see an especially cool astronomy or other nature photo my first reaction is to wonder if it’s AI generated. The fact that some clearly are fake doesn’t help.

Would you like a little red light with your moon?

Also, while many AI answers are slop, the most common way I catch them is that they’re too good. My students are gen-ed non majors so they shouldn’t be giving graduate level responses.

I completely agree with the problem here, but I also understand why they use AI tools. At this point, it is so damned easy to plug a question into a chatbot and get an answer that it takes a major effort of will not to do that.

I read a large part of Assembling California to my daughter as bedtime stories.

Why wouldn’t you want to watch an angry old man yelling at the camera?

It was amazing walking around the war memorials in London. You see all of the usual triumphant imperial symbolism for all of the earlier wars, and then you get to the WWI memorial and it’s a completely different story. This was not a war that was won, it was endured.

I’m new here, but I can see the similarities to an old social media platform that will remain nameless. I’m sorry I’m on the wrong side of the planet for today’s eclipse.
