comment What new breakthrough energy technologies are close to being realized?
@Ben Crowell This old joke might have its roots in economy: in 60s experts extrapolated money spent on study of fission. With similar money probably their estimate was correct, but money were completely different. Then in 70s experts extrapolated money spent on important and perspective technologies, then in 80s just on science, and so on and so fourth...

comment How beam focusing looks like in electron microscope?
@mmc Ok, for SEM I was wrong. Our experimentalists use TEM only.

comment How beam focusing looks like in electron microscope?
I know that my answer is not an answer. Your question was about electron microscope though. Electron lithography is another subject. I'll just point out to the fact that a lot of good labs have their own electron microscopes. Very few have their own electron lithography machines. Probably, due to significantly higher cost and complexity.

comment The philosophy behind the mathematics of quantum mechanics
@Marek Ok, I got the point. Indeed, I sacrificed too much of formalness (I thought of measurable functions but wrote continuous to be less boring) to simplify the idea.

comment The philosophy behind the mathematics of quantum mechanics
@Marec, when one says "actually sheep are mammal" it is obvious that not every mammal is sheep. Surprisingly, it does not work when you speak of Hilbert spaces. I was trying to point out that Hilbert space is not something complex and/or artificial. It is something which is studied at school but at the different level of abstraction.

@Karsus Ren, If you read my answer carefully you'd mention that I did not say that Hilbert spaces are necessarily composed of continuous functions. Probably I should had used 'e.g.' instead of 'actually'.
