An old friend. My first calculations of near-field diffraction were on the original 8088 processor, and my near-field microscope for my Ph.D. thesis was controlled in assembly language by two IBM ATs with 80286 16 bit processors. Microscopy has never been the same since.

There are at least some advantages to insomnia... SF bay by moonlight

Absolute madness. Future generations will curse you for what you've done to yourselves.

Thanks for the reply, Peter. X is not great for nuance, but here's a video of a 10 min talk I gave at the recent Lindau meeting. The discussion with the Young Scientists was fun, both as recorded here and in the days afterwards. mediatheque.lindau-nobel.org/recordings/421…

In anticipation of the Polaris Dawn launch on Tuesday, which will feature the first commercial space walk, here's a video of Ron Evans space climbing outside the Apollo 17 command module while 184,000 miles from Earth, 52 years ago: youtube.com/watch?v=HlLTw7…

“The existential risk to NASA is not failing a mission, but failing to deliver jobs”.

And even the picture on the right is out of date. Chopsticks catch hopefully soon, and HLS hopefully in just a few years.

Dave Collum Them being stuck isn’t funny. But…

The Two Towers: My usual morning routine is to work for a couple hours before thinking things over on a hike through Berkeley's Tilden Park. This AM I was greeted by the two suspensions towers of the Golden Gate Bridge peeking through the fog.

Well, I was wrong about Starbucks ("who would be dumb enough to pay this much for a cup of coffee!"), so maybe this isn't as stupid an idea as it seems either. I seriously doubt it though.

There is no such thing as disinformation. Just information of differing proximity to the truth. Even outright lies inform as to the trustworthiness and motives of their source. I'm grateful for X and their unwavering support of free speech in the face of enormous opposition.

The first of what should be many gorgeous views. Highest apogee flight since Apollo. arstechnica.com/space/2024/09/…

A long but important read of the regulatory issues delaying the development of the Starship program. Yes, environmental and safety concerns must always be addressed, and have always been done so conscientiously by SpaceX, but the nature of current regulatory processes allows
