The industry term for cable laid on the sea floor really is "Submarine Cable."

Pi is a real number, but it isn't rational. Maybe that's what you were going for here.

You need to look up the meaning of a mathematical theorem: A statement that has been proven on the basis of previously established statements, such as other theorems, and previously accepted statements, such as axioms.

A theorem is a not the same as a scientific theory, even though the words sound similar. You might have intended to talk about axioms, which are a set of given restraints for a particular mathematical system.

There are two schools of thought of the question of "Is math a science?"

1. (1) The mathematical method follows a similar pattern to the scientific method, so it is science (or a least science-like).
2. (2) Math is the pursuit of interesting descriptions of possiblities. Mathematical 'theories' are interesting or uninteresting, not right or wrong.

I follow the second school and I think most other mathematicians do as well.

That made me smile. Thanks.

440VAC 3 phase is not common in the US. 480VAC is common in the US. 380VDC is a common intermediate voltage for switching power supplies. This means that a 380VDC input supply can be made using a relatively small mod to an existing supply.

Real-time traffic information. Cool feature. It is not included in the GPS signal (just as you said), but is instead delivered using one of several other formats (FM radio, for instance).

New Shimmer - It's a floor cleaner. No, it's a dessert topping.

The SD card can also be encrypted with an easy to set (and easy to forget) option.

You are correct. But I have used an 8-track cassette :)

This is a lot off-topic, but: 8-track studio recording was the hot thing in the late fifties when the Ampex 5285 and other multi-track studio records came out. Multi-track analog recorders remained very popular until digital multi-track started to replace the old analog units in the mid/late 1990's. Those studio 8-track machines do not have much in common with the continuous loop cassettes we also call 8 tracks. From a technology standpoint, Kodachrome has just as much reason to still be around as the 8-track cassette - none. From a nostalgia standpoint, maybe there's room for both.

I also have graphite under the skin on one finger from the same sort of accident. I wonder how comon it is.

Broadcast television is still free, over the air, and have always had commercials (in the case of PBS stations more subtle, but still there). I don't remember anyone promising me that cable would eliminate commercials. Provide better and more reliable picture quality and add choice, yes, but not change the actual programming delivered.

Where I live there are hundreds of publicly-accessible real-time cameras pointed at highway interchanges and major intersections.

FM-200 is not Halon, it is the Dupont brand name for a non ozone depleting Halon replacement - heptafluoropropane. Still yet, the deployment works exactly as you describe.

I wish Sprint phones would roam at EVDO speeds on the VZW network like it did on the (former) Alltel network. Not gonna happen, but it would be nice.
