Thanks Paul. That article about Arthur Ashkin was fun to read. I remember as a student in the 1980s reading about the optical tweezers and thinking how wonderful that concept was. It came around the same time (for me) as the scanning tunneling microscope, so lots of exciting stuff. It continues these days too!

I had never heard the term Ashkin pressure. I have never heard of radiation-driven implosion for nuclear weapons being related to it, but now I can see it might. And it must be complicated! Wikipedia https://en.wikipedia.org/wiki/Arthur_Ashkin has this:
Ashkin ... obtained his BS degree in physics at Columbia University in 1947. He then attended Cornell University, where he studied nuclear physics. This was during the era of the Manhattan Project, and Ashkin's brother, Julius Ashkin, was successfully part of it. This led to Arthur Ashkin's introduction to Hans Bethe, Richard Feynman and others who were at Cornell at the time.[1][19] He received his PhD degree at Cornell University in 1952,[20] and then went to work for Bell Labs...
So does "Ashkin" pressure, as you used it, refer to Julius or Arthur?
The Schott glass article reminded me of a quip a manager at LLNL said to me in the 1990s (?), "This project has sucked up all the XYZ glass available worldwide for the next N years." I don't remember the values of XYZ or N.

Arthur.
