I went to a summer school last year and one of the professors told us about the book where he went into detail on most of what he had explained. It was from a major publisher on science textbooks.
He told us to go ahead and buy it, he was planning on getting rich with the 12 cents he got per copy sold. Yes, that's it... the author was getting 12 cents of a dollar per book sold!

If your professors are arranging to get their books sold by their colleagues, the must have some great deals out of textbook companies.

[...] is that the great strength of a password is its portability. If I need someone to do something on my behalf I can tell them the password and they can do it, and it gets done. This may sound like a weakness on the surface, but the alternative non-portable method would mean all those things wouldn't otherwise have been done, and ultimately systems are designed to do things.

Aren't you extrapolating from posting the latest coolest pic you have on your Facebook account a bit too much?
If you have a job where security credentials are important and your boss finds out your giving your password so someone else can "get stuff done", you'll find yourself in a bad spot (or you should at least)! There's a reason even Facebook says usernames and passwords are personal... it's because they're meant to be, to protect you (apparently from yourself). Hell, this statement you wrote seems to me the best reason to go on and implement biometric style authentication. At least people will stop giving their passwords to others... Do you also give people access to your bank account because you need them to do something for you? And you sleep comfortable after that?

I think the regular old password is the best balance you'll ever get to authentication. Why waste energy trying to build a better mousetrap?

And since when what you think is law? World seemed to work pretty well in 1904 and yet, by 1905, a certain guy named Einstein had proved there was a speed limit (among other things). Why did he even waste energy thinking about that when we clearly cannot even go beyond the nearest rock?

Well, mass spectrometers have the (slight) disadvantage of needing a charged "particle". if it's neutral (and for whatever reason you cannot charge it), this seems like a possible solution.
Granted, it looks like it has a lot of drawbacks of its own (like the heating part).

Will screw us?! If you already know this is most likely going to happen and you consider it a screwing factor, why the hell do you go on and buy it on the first place?!

It's the same as in 11.4.
Whatever is commented out keeps the default behavior. As already mentioned in this thread, the default is allowing root logins. Your change to "No" prevents root access (provided you restarted the SSH daemon). Of course you can use "without-password" to allow ssh-key based access to root, if you still have a need for it.

My view of it is that there aren't that many basic concepts to discover in the back of your garage. Particle accelerators, high-field NMR machines, electron or AFM microscopes, huge ground-based or orbital telescopes are needed to make the next discoveries in their respective fields because the easy stuff, that could be seen with bubble chambers, low-field magnets, optical microscopes and small telescopes was already discovered. It's a matter of diminishing returns.
Scientists have been doing their jobs for hundreds of years, no one is going to discover an improved version of the laws of gravitation with a 100 dollar telescope. What may come out of observing dark matter was obtained with multi-million dollar equipment, collaborative effort and brilliant minds going over and over the same thing.

Granted, there may be things to discover that can still be attained in a garage. In hindsight everything is easy, but if no one is looking, there may still be amazing things still to observe in your kitchen lab. But expecting the cure for problems of the world to come out of a bunch of semi-amateur scientists is betting on the wrong horse... it may happen in a field or two, but it won't be the future of science.
