I'm moving to Germany in a couple of months and have a few questions about using various 110V US-purchased appliances on the local 220V power. Specifically the 50Hz/60Hz issue - how big of a deal is it? My understanding is that anything with a motor may have a shorter lifespan and run somewhat less efficiently (and of course anything that uses AC for timing will run slow), but any other issues?

I have been playing around with Audacity recently trying to understand a bit more about sound in general. One question I'm having trouble wrapping my head around is: How does Tone and Frequency relate? For instance, the 2600 Hz is a high-pitched tone. Does that mean that anything that produced that same tone would be at 2600 Hz? And does it mean that for the entire range of human hearing -- all of those Hz -- that one tone corresponds to a particular frequency? I am looking for some basic explanation or even tools to play with...

If an alien located on a planet 100 light years from here was to switch on a big, multi-frequency radio receiver, and record all the noises coming from outer space for the
next hundred years, on all frequencies, how many soap operas, advertisements and new broadcasts would they pick up from Earth? Would a mass-market radio, similar to our Earthly equivalents, pick up anything? Over time, as the number of Earth transmissions increases exponentially, would the alien pick up a cacophony or a damp fizzle?

Several years ago, I saw a website with a fun little flash or javascript applet thingy where you could build little tensegrity structure creatures, then have oscillating movements applied to the pieces, so that the structures would seem to "walk". I don't remember what it was called! From memory, one of the simpler structures looked sort of like
this. What was it? Is it still online?

Hypotension/hypovolemia as a low-pass filter: I got cut, I went into shock, and then everything started sounding funny. I'd guess it was a 40 dB (±10) rolloff, which began near 200 Hz (±50) and left me with nothing above 1kHz. How in the world? Story, discussion of numeric estimates, off-the-cuff physiological speculations, etc...
