Good point, that nonlinear processes generate frequencies not present in the input. One of the biggest challenges in making analog circuits with good-sounding clipping distortion is designing proper lowpass and bandpass characteristics int

For a circuit meant to be used with a guitar or similar instrument, it is practical for many purposes to use a much lower sampling rate, e.g. 22 KHz. The frequency content beyond 10 kHz is quite limited. I have used conventional LTspice t

Centrifuges? IIRC, that was not used for uranium separation until the 1960's. At Oak Ridge TN were the Y-12 electromagnetic separation (calutron) and K-25 gaseous diffusion separation plants.

The Spectrum article was very informative. Thomas Pynchon riffed on this story extensively with his iconic (for geeks) 1974 novel "Gravity's Rainbow" in the tale of "Byron the Bulb". Another of Pynchon's pres

Another WP feature that existed before Microsoft Word itself existed (indeed, before the IBM PC existed) was the ability to create a "Table of Authorities". Word Perfect was very responsive to the needs of legal word processing.

As an electronics hobbyist since the 1960's, the only places where I have ever been able to walk in and buy parts with good service were quirky little shops run by like-minded proprietors. I do not think a corporate business model for

I picked up the last 2 rolls of silver-bearing solder at my local Radio Shack last weekend. The manager told me he would be ordering more, and not to worry about bankruptcy because a chain with 4000+ stores would not disappear overnight. A

The g-load experienced during the re-entry is more a function of the entry trajectory that is flown than the speed of entry. For example, the crews of several Soyuz missions experienced 8+ G's when the so-called "ballistic" r

The other reason is that the screw speed for a large vessel is about 100 RPM. It is better if the engine can drive the screw without a reduction gear that would decrease efficiency. http://www.gizmag.com/go/3263/

Of course, you could be monitored by the laser bounced off your window, or by your EM leakage. But it is an order of magnitude cheaper and easier for the commercial/governmental entity to use your own voice-enabled communications devi

National Instruments' Labview environment also fits in this category. To me it feels like an analog of an electronic schematic diagram editor. I find that it turns into a visual mess as the system becomes complex. To counteract this,
