The old name was a hoot, too. "MD", as if doctors did anything but use it, like the rest of us.
I do remember seeing, in the early 1970s, a dispenser for those wax paper-like seat guards in a restaurant. It had the then-current "MD" logo, but it had been vandalized to read "VD"
Dinosaur machines had one good reason to use BCD: limited speed and memory. BCD nibbles required, at most, a bias factor to convert to your favorite 5- or 6-bit 'display code' for output, or the reverse for input. No converting binary to decimal first.
My wife has very sensitive skin, so she cleans up after #2 with an aloe-soaked sheet. The same things parents use to clean up when changing diapers. Comfortable and effective, and much less likely to plug up the plumbing than the wad of TP formerly used.
My skin isn't so tender, but the efficiency is so impressive I'm doing it now, also.
No freakin' wonder performance and mileage bit. I had a hand-me-down '78 Chevette w/ manual trans. Adequate (barely) acceleration, and 29 mpg highway as long as you cleaned the carb regularly.
Buying an automatic Chevette was as stupid as buying an automatic Mercedes 240 Diesel from the same era. Likewise, the stick Benz was acceptable.
Shielded boxes on satellites add weight, taking away from useful content. Also, secondary radiation from the shield may destroy the components, anyway.
The US does not use fission-based plutonium reactors for its civilian deep-space probes. Rather, it uses the heat from the decay of a non-fissile isotope, Pu-240, to power thermocouples for electric power generation.
A physicist, an engineer, and a mathematician were all spending the night at the same hotel.
The physicist goes to sleep, and is later awakened by the smell of smoke. An object in the room is on fire. The physicist pulls out an infrared detector, aims it at the fire, observes the amount of energy coming off the fire, works out how much water it will take to put the fire out, does so, and goes back to bed.
The engineer goes to sleep, and is later awakened by the smell of smoke. An object in the room is on fire. The engineer builds a scale model of the object, ignites it, notes how much water it takes to put it out, scales up to determine how much water it will take to put out the original fire, does so, and goes back to bed.
The mathematician goes to sleep, and is later awakened by the smell of smoke. An object in the room is on fire. The mathematician sits down with pencil and paper, works for a few minutes, exclaims "Aha! A solution exists!" and goes back to bed.
Lasers of shorter wavelength, and steppers of finer intervals, pace transistor size, I believe. Maybe the business types figure that buying the latest-and-greatest (and costly) fab equipment can only be justified at intervals that fit the Moore's law curve.
It could the following (borrowed from something I saw on rec.aviation.military):
(1) Pilot dumps unburned fuel, forming a cloud of air-fuel behind the jet. There are valves to do this.
(2) Pilot activates afterburner to ignite cloud. It's safe to do as the plane's speed is greater than the flame front speed.
Why do it? It's one way to reduce aircraft weight below maximum landing weight (some planes can take off with a higher weight than landing weight) in an emergency.
Roughly 10 years ago, a civilian researcher doing work for the Navy took a laptop out to an aircraft carrier. It was fine until after return, when it wouldn't boot. IIRC what the repair guy said, the g-forces damaged the hard disk.

Why do the British drink warm beer? Because Lucas makes refrigerator motors.
Rather like my 1981 M-B 300D (375 000 miles!); one engine, one water pump(!), but 3 (American-designed) automatic trannys...
my girlfriends automatic

Ford's answer to the Chevy Nova
Pintos were closer to Chevette in size. Ford's Maverick was roughly Nova-sized.
Helium...almost never has a charge
On earth, that is. In stars, helium is always ionized, as is everything else!

(told to me by Bruce Hill in 1982)
Chemists are frequently regarded as second-class physicists in many circles. At least, they [do] "rate."

ISTR that arguments similar to your points 1 and 2 were used in setting a M1.7 (or so) limit for the F-16 and F-18.
And, many of them use FORTRAN, because they have had one class in programming way back when, or picked up McCracken's book and taught themself.
Gort? Not Klaatu?

Reactions do exist, but may not be cost-effective in mass production quantities.
The mainframe world has had optical interconnects for some time now; I saw Amdahl machines so arranged around 5 years ago or so.
omit the smiley, get a straight response. oops :)

It's also quite a spectacular airshow trick.
Do you want to learn group theory?
I'll stick to learning applications of group theory. Symmetry groups are hard enough.

1987 -- 13" RGB monitor and ADB-based Extended Keyboard (aka the barge)
1994 -- Power Mac 7100/80 (albeit with a 300MHz upgrade board from 1998)
There's a boatload of 8-bit stuff, it's just all in the embedded world.
I must have seen it (was there 1989-91) but it doesn't, er, ding a synthesizer... :)
