At present, hydrogen comes chiefly from natural gas. Big Oil (which is also Big Gas) would love a new market that looks green, but isn't (that carbon has to go someplace).
As to noise, I'd had the opposite happen. I lived in a quiet place for all of my life. One week away, in a noisy place, and the first night was TOO QUIET for comfortable sleep! Odd!
The shuttle was originally conceived as the earth-to-earth orbit and return part of a 3-part transportation system. Part 2 was a earth orbit to lunar orbit and return vehicle, Part 3 was a lunar orbit to lunar surface and return vehicle. Think of a crude oil tanker too big to dock, with transfer vessels at either end.
The shuttle was supposed to have a reusable liquid fuel only booster vehicle. As both accidents originated in the alternative boost system (solid rocket joint, external tank insulation), von Braun's condemnation of it seems spot-on, although of course it did work something like 98 percent of the time.
Some calculators (old H-P, IIRC) do symbolic calculus, at least of one variable.
Mathematica excels at symbolic calculus. I've heard Dr. Wolfram play up Mathematica-oriented curricula. This was around 1996, so perhaps there are comparisons as to the effectiveness of Mathematica-based learning vs lectures, homework, and exams.
#1: It does not matter whether I'm personally impressed. However, broad-brush statements about not being able to find good people suggest to me that your attitude might be getting in the way of finding good people.
#2: Usually my generic letter is a good fit. If the job post gives me information (such as which industry they're in, it's amazing how many figure "major tech firm" is sufficient to describe them), I'll tailor my letter.
That business in India could have easily been located in the United States
According to this web site, the same chemicial was produced and stored at a Union Carbide plant in Institute, West Virginia, USA. Safety was neglected to the point that state officials fined Carbide that year (see same page). I remember some mention of this in the press at the time.
Another neon story, heard at a lecture at the Computer History Museum.
When Systems Development Corportation in Santa Monica decided to use Johnniac for timesharing research, some electromechanical terminals were connected to provide user I/O (I believe it was only used for batch jobs previously). The data lines had neon tubes for noise isolation. Unfortunately, the breakdown voltage varied with ambient light, particularly UV, and there was just enough UV in the fluorescent lamps to make a difference between "room lights on" (worked OK) and "room lights off" (mysterious errors in overnight batch jobs, where the operator switched the lights off laeving the room).
Eventually fluorescent lamps were affixed in the bottom of the machine, where the neon lamps were, to prevent problems. They are still there.
My understanding is that old galaxies had enough fuel in a small enough space to condense into masses that became stars by gravitational compression. Are young galaxies simply areas where this process took much longer, or is there more to it?
You mean like the Univac 1230? In one control application, the software group set up some code in the background loop to make the A and B registers blink like theater marquees. Cool and a half. Also a rough guide to system load; as it did more, the speed of the marquee slowed down.
It was the same during my grad student days, from 1991 to 1997. I never lectured, but ran lecture sections (explain the lecture, which I attended, to those who asked), ran a wet lab, ran a computer-based-instruction lab during my first 2 years. After that, it was grant money from my advisior, except for one ill-funded quarter where I was a reader (graded midterms and final) for another professor.

Fun thing to burn: ammonium dichromate.

It's refreshing to see Robert Ballard speak candidly about the shortcomings of a technology he helped to develop. Usually, hype prevails.

The cartoon "For Better or For Worse" covered Internet 'research' at the grade school level today.
Danke schoen.

Edison Project: No gov't funds, yet fell apart in a few years.
Also, Einstein had an assistant (name?) to do his math; perhaps the quote was meant in humility.

No, jest a spill checker.
Good luck, Wiki-folk. As long as it doesn't degenerate into a high-noise free-for-all, like, uh, Usenet or /. :)
But you still get to be President.
If Congress was R rather than D at the time, Nixon would have got away with everything, as Lyndon Johnson did.

The end product may not have been toxic to humans, but one of the intermediates, when mixed with water, was.
It was an insecticide plant, making Carbaryl (tm). Methyl isocyanate was a precursor.

What about research academic environments, which demand openness as an expression of their values? Should they be made to toe the security line?
(I do have someplace in mind, but am sure it's the same elsewhere. I don't want to be like the sports press, harping on J.G. and B.B.)

By ball-and-stick model I meant the illustrations of clusters that accompanied the talk or poster.

Yes, at least in 2000.
