Pretty sure they’d be negative

Yes, these would be the local conditions where the nucleation and growth occurs, so mainly in the clouds. Can also be modeled in a lab doi.org/10.48550/arX...

Saturation is 100% relative humidity. Supersaturation is the amount of water vapor in the air above 100% RH. This excess is not stable and will precipitate out - so here it basically measures how fast the snowdrops will form

Measurement of a Quantum of Solace

Yes, I think Hillier was hired by RCA to commercialize his electron microscope. I remember meeting him as a grad student when he came up to Cornell to visit John Silcox in the early 90’s

and @joachim123.bsky.social was very briefly a postdoc (one of 3 labs he worked in during his fellowship in the US)

That would be Ben Siegel. He joined Cornell in 1948, after having worked on the Manhattan project looking at diffusion membranes with TEM. James Hillier (then at RCA) donated an RCA TEM to Cornell, and found funding for student fellowships. Ken Downing did his PhD with Ben, as did Earl Kirkland

I’ll be teaching the Hall effect in solid state this Tuesday. Let’s see if I can sneak it in

Time to break it up when they dosey do

The scale of the room doesn’t come across that clearly in the picture. The cones on the wall are six feet deep to absorb long wavelength waves, and the entry in on the 2nd floor of the building with a full floor of empty space below the mesh you walk in on - not for those with a fear of heights!

Our microscope lab was in the same buliding as the anechoic chamber - in one of the old varechoic rooms. The acoustics folks showed us how to get things quiet.

Astro folks might want a turn?

We had 35 participants at our summer school a few weeks ago testing this on their laptops. Turns out a Macbook M4 pro is almost as fast as a 10GB slice of an A100. From the school, here is a 1-hour reconstruction. (Data took a few seconds to record at the school in a crowded scope room)

Good use case for comic sans
