Borepatch: Man, he puts a lot of intellectual effort into what is essentially complicating a cornflake.
Candide III: This is interesting. Since (a) slicon’s thermal expansion coefficient is ~5e-6/K, (b) for visible light they would need about 200nm path difference for a quarter-circle phase shift, (c) they can hardly heat elements to more than 100C, and realistically about 10C, and (d) they need several hundred emitting elements for a good approximation to a focused beam, 0.5mmx6mm seems reasonable. To reduce linear dimensions, they can fold the light path several times by folding the wave guide.
Bob Sykes: When I was taking microbiology and biochemistry in the late 60′s, the proton gradient was just being proposed. Biologists assumed that fermentation came first, especially as it was known that the early Earth had no free oxygen. But fermentation is enormously more complicated than respiration, and most of the fermentation pathways also double (in reverse) as synthesis pathways. Once the mechanics of respiration were known (thanks Peter Mitchell, 1961), the question of which came first...
Bill: This has already been blogged to death – young men have noticed that the old social contract between men and women regarding marriage no longer obtains, and why work yourself to death if women won’t value it? I’d be curious to know the minimum economic level of a young guy who wanted to be comfortable with maximum leisure time. What’s the best living arrangement (other than with parents)? What freebies are available? Etc.
Bill: I can’t find out how many women buy guns for their boyfriends, but I did find a story about a guy in Georgia whose girlfriend bought him 64 guns in less than three months. Maybe it doesn’t take that many gun molls…
Redan: My father and uncles were working in Henry J. Kaiser’s Richmond Shipyards in California at the time (a damn good job in the Depression). They all tried to volunteer for military service on Monday 8 December, but were initially turned away, as shipbuilders were ‘essential war workers.’ Once replacements could be hired by Kaiser, they re-volunteered and were accepted — in 1942. Today, the Rosie the Riveter/World War II Home Front National Historical Park occupies the site of...
Redan: I first saw it in/on a SERE course, years ago. No way could such a movie be produced today, given the themes, and the lack of a kickass grrrl character.
Alrenous: So what, like 50% of men? I don’t know anyone who’s ever been arrested. So it’s probably ~100% in some areas.
Gaikokumaniakku: “The obvious problem with this lifestyle occurs as they age and haven’t accumulated any skills or experience. As a 30- or 40-year old man getting married and needing to provide for a family, job options are extremely limited.” I’m sure the corresponding cohort of young women will solve that problem by refusing to marry these men.
Eli: Government to the rescue with a “solution” to a “problem”. Twenty-something males playing video games is a symptom, not a problem.
