When I later learned about spread spectrum multiplexing, that's when I understood your brain is doing the equivalent of orthgonal frequency division multiplexing (which is the technology used for LTE).

I think that's taking it a bit too far. OFDM allows your cell phone to filter out all but one channel, so that all you hear is that channel. Whereas, when I listen to Haydn's Trumpet Concerto, I can't help but hear the orchestra too, even though I can recognize the individual instruments.

The name comes from frequency modulation synthesis - you modulate the magnitudes of the different frequencies (overtones) to alter what instrument the sound sounds like.

Actually, that sounds like additive synthesis. FM synthesis entails the frequency-modulation of a single note with a rich upper-harmonic content (e.g., a sawtooth wave.)

I'll second the amazingly talented part. (The pretty part is obvious.)

Hearing her sing reminded me of the first time I heard of overtone singing. It was in Stimmung, a piece by German avant-garde composer Karlheinz Stockhausen for 6 vocalists.

You're right that overtone singing has been around for a long time.

Lightning can have an increased probability of striking in certain locations, such as your example of ore deposits (due to increased ground conductivity) or tall pointy conductors such as antennas, spires or wet trees (due to stronger electric fields near the points.) However, the occurrence of lightning strikes in a given area of land is still random, just not uniformly so.

Lightning can still strike at a location that does not seem like a candidate for strikes, if the conditions for a discharge are favorable at that location at a given moment. For example, you could be in an open field at a safe distance away from your ore deposits, with your finger pointed upwards, and you might be a better path to ground for the lightning strike than anything else around.

Also, just because something is random does not mean it isn't physics. Physics deals with random processes all the time. There are entire subcategories of physics devoted to them.

if you truly study relativity, and i mean read Einstein's essays and not just the summary on wikipedia...you realize the linear view of time is just the way our electro-chemical computers (brains) process information. but in relativity, an atomic clock up in an airplane experiences time an a slightly different rate than you on the ground. since it is further from the earth.

This has nothing to do with whether the clocks are electro-chemical or atomic. It has to do with reference frames.

Two clocks in the same reference frame will experience the same proper time, no matter what they're made of.

Two clocks in different reference frames will not experience the same proper time. The frames can be different due to relative motion or due to different local strengths of a gravitational field.
