She also has a stereopticon, which is sort of like those ViewMasters that I used to play with as a kid. It has a viewport with two lenses that look through at a little mounting place where you place a card that has two identical (or nearly identical) pictures side by side. The effect is that when you look through the viewer at the card, the two identical photos merge into a 3D picture. It blew my mind to think that my grandpa was playing with 3D when he was a kid.
This effect was achieved by taking the the two photos from slightly different angles. The idea is that you see in 3d because you are able to see any given scene from two different angles at once, allowing you to perceive depth.
By using a camera with two lenses, spaced apart much as the eyes are, and exposing images from both lenses onto the paper in the proper manner, you can fool the brain into thinking that the two images are actually one, with appropriate depth signals.

I think scientists -- and businessmen -- can learn a lot from looking at the way things were done in the past.

The trick about things with a lot of angular momentum is that they have a certain axis (vector) about which that angular momentum exists, and that AXIS resists rotation. Translating the axis but keeping it pointing in the same direction is easy.
One example of this is that if you were to make a flywheel-powered automobile, and you set the flywheel spinning with a vertical axis of rotation, then your car will be able to turn corners without difficulty but transitioning from a level road to a hill will be a disaster (incidentally, the solution is counter-rotating flywheels).
Before this gets even more off topic, the point is that the story about the drum drive either has some details wrong, or it is apocryphal. If the drum drive has a vertical angular momentum vector, than the forklift should have no troubles unless it tries to go up a ramp. If the drum is mounted with a horizontal rotation axis, then the forklift WOULD have difficulty turning, but the drive would NOT stand on one leg -- it would simply resist the turn, probably holding its orientation while the forklift turns underneath it (of course, it could fall off the edge of the forklift....)
Re:Drum storage (Score:1)
Oops, I had typed in the last sentence as an afterthought, but I just realized that the part about it not tilting was wrong.

So it must be that the drum drive had the platter mounted vertically (horizontal axis of rotation), since if it were mounted like a dinner plate, there would be no problem.

Re: PAL/SECAM Betamaxes (Score:1)
The multi-system VHS VCR my parents used to have recorded NTSC in all three speeds, but only two (SP and LP) were available in PAL, and at the time we had it, most PAL-only VCRs that other people had used SP only. When we brought a PAL tape recorded at LP speed to a friend's house, we were surprised to find it didn't play. (This was in the late 80s...things might have changed since then. If the Brits have more than four TV channels available to them nowadays, anything is possible. :-) )
Also, E-180 tapes (VHS videotapes for use in PAL equipment have their sizes start with E, not T) are closer in length to T-160s than T-120s. The speed at which the tape moves past the heads is slightly lower for PAL than for NTSC. (525*30=15750. 625*25=15625. In each second, PAL writes fewer scanlines than NTSC.) The difference is slight, though...if you put an NTSC signal on an E-180 tape, it'd get only about a minute and a half less recording time than if you put a PAL signal on it. Come to think of it, E-180 tapes would be closest to T-180 in length.
You might've noticed that T-180 tapes have been on the shelves here for just the past few years. E-180s have been available in Europe much longer than that (at least since the mid-80s) because it was more necessary for them, given that they were stuck for the most part with just SP. With the slower speeds available in most NTSC equipment, you were better off using more durable T-120s. (Why a multi-system VCR supported PAL LP recording when most PAL-only VCRs didn't is beyond me. Given that this particular multi-system VCR also boasted Dolby B noise reduction (it was a 4-head Hitachi with programmable digital tuning, infrared remote, and some other goodies...probably one of the better models available in 1984 or '85), maybe it was just some of the higher-end models that did PAL LP recording, or maybe they "borrowed" some of the capabilities put in for NTSC compatibility.

We found two good leads. One is a pure data conversion company, which has a huge list of formats up on its website which it can convert between. One would assume that they have a database of the format information, though the gods only know whether they'd release any of it. (If it's magnetic media, it's on that list, I think.

If anyone could persuade these folks to give up the goods on the formats themselves (not the conversion tools, since they've chosen to make their living off of them), it would probably do us all some good.

Re:The Technicolor story. (Score:4)
Here is an example of how a single shortsighted business decision resulted in a huge cultural loss.
Around 1978, the Technicolor corporation stopped using the dye imbibition process.
Dye imbibition printing was the first commercially successful color movie process. With this process, instead of shooting a single color negative, the camera contained three negatives, and color filters. The result was three sets of negatives, one for red, one for green, and one for blue.
To make the final prints, each of the three negatives had to be individually cut and assembled to make a final negative. Then the negatives were printed onto a special film stock called "matrix" film, and developed using a special chemical process that hardened the film in proportion to the exposed silver content, then washed away both the silver and the unhardened emulsion. The result was that instead of a visible image on the matrix film, the color density was represented by emulsion thickness. Finally, these three matrix films were used as printing plates to transfer dye to the final release films, one color at a time, cyan, magenta, and yellow. The thicker parts of the matrix would transfer more dye, and the result was "Glorious Technicolor." Modern color film uses organic dye couplers, which tend to fade over time. Because Technicolor was using a printing process, they had their choice of what dyes to use, and they chose very bright, intense, fade resistant, acid based dyes. A properly made Technicolor print from 1939 looks the same now as it did the day it rolled off the printer over 60 years ago.
When color negative film was invented, the process changed slightly. Instead of making a matrix film from each of three negatives, all three matrices were made from the same color negative, using different color light filters to pass the desired color.
This process was very gentle on the negatives. A single matrix could be used to print hundreds of release prints, so the original negatives only had to be run through a printer occasionally when a new matrix needed to be made. The matrix stock itself was estar based -- an extremely strong, durable film stock that does not deteriorate over time like nitrate and acetate film.
When Technicolor shut down their dye imbibition production line, they were left with warehouses of matrix film; the printing plates for nearly every feature film ever printed in Technicolor, all meticulously cataloged and carefully stored.
In many cases, the matrices represented the last existing color record of the films. Color negative film, especially early color negative film, fades away over time, and release prints wear out, but the black and white matrices were completely stable. In many cases, the original nitrate negatives for many color features had already turned to dust, leaving the matrices as the ONLY existing preprint material available for countless films.
These matrices could have lasted nearly forever. Now that Technicolor has revived the dye imbibition process (The new, beautiful re-issue of Alfred Hitchcock's Rear Window is in true Technicolor), had Technicolor saved their matrices, they would have the ability right now to reprint nearly every film that they had ever made. In perfect color.
Instead, seeing no use for this "obsolete media", they destroyed them all.
Now, the cost of restoring a single Technicolor film, if it can even be done, can run into the millions of dollars. The result is that it is hardly ever done, except for a very few extremely high profile films, like, for instance, "Gone With The Wind" or "Rear Window". What a loss.

They could break around SPLICES though
Wire recordings have the advantage that they can last forever
The disadvantages of wire recordings were that the format was mono-only, for obvious reasons, and the frequency response was limited.
But the recordings last forever. You can't say that about recording tape, CDRs, or DVDs.
The recorders, however, are old tube devices that have to be maintained like an old tube radio. -- tubes and capacitors need to be periodically checked and replaced, and god forbid I should have a crucial mechanical part break

pneumatic tubes should be bundled with DSL (Score:5)
The Internet's big flaw is its inability to trransport, say, kittens or french fries. Right now, if you want french fries over the 'net, you need to place an order which is then delivered by a person. Pneumatic tubes would make it possible to eliminate all human interaction.
With efficient digital switching systems in place, today's pneumatic tube networks could be made efficient enough to handle fully-automated person-to-person routing of the cargo cylinders.
