Measurement is a classical process by definition (even in quantum mechanics), so I can only conclude that a "quantum measurement" is a normal measurement that has gone through a marketing transformation

It was like getting a preview of what the adult mind must be like, and I wasn't sure I liked it but I couldn't look away.

My parents had a bunch of these collections, and as a kid in the early 90s I read them with a kind of perverse fascination. There were clearly points of appeal to kids, but the focus was squarely on "adult themes" (risque, political, banal).

Good correction, which shows that I misremembered / omitted some context in my summary.
Weiss came up with the idea of an optical interferometric gravitational wave detector, which eventually became LIGO.

Much better to read his summary of what happened than mine:

As someone who is never able to maintain focus on a single problem for more than a year or so, I'm so glad there are people like this in science.

(And of course I worry that the modern culture and pace of science is pushing them out)

Rainer Weiss life story Rainer Weiss life story

Just found this longer, and much better telling of the story: www.kavliprize.org/rainer-weiss...

Looks like I mostly remembered things correctly, but the full story is much better than my telling.

10/10 "Wait, could you actually detect a relative change in distance of order one part in 10^20?" He spent all summer thinking about it.

And that was the beginning of his obsession. It took 48 years from that moment to the first actual detection of a gravitational wave.

9/ The point of the problem was to show that there is a relative change in distance between the masses less than one part in 10^20, and you go "ahh, got it, the effect is negligible" and you move on.

But during the summer after the class ended, the problem stuck with him and kept bothering him.

8/ It was a simple homework exercise, and he showed it as part of the colloquium: the solution takes less than a page, and he claims that everyone in the class was able to solve it correctly.

7/ At one point he conceived of a homework problem that would make the point to his students that dynamical effects in GR are extremely weak. So he designed a little problem where you imagine two free masses passing light back and forth to each other as a gravitational wave passes by.

6/ He was assigned to teach the General Relativity course, which at the time was in the Engineering department because no one in Physics wanted to teach it. But Waiss (in his description) didn't know any relativity. So he struggled all semester to stay "at best one day ahead of my students".

5/ Weiss finished his PhD, bounced around as an instructor a bit, and eventually managed to get a junior faculty position at MIT's Research Laboratory for Electronics.
