They don't. Although the electrical energy itself travels very quickly--some large fraction of the speed of light in most types of insulated wiring, nearly c in uninsulated wires, the electrons themselves travel very, very slowly. The speed at which they move is dependent primarly upon current...

This is just a simple differential current amplifier. There are three components (not counting the battery) which must be connected the right way or it won't work. There is the meter itself, of course. Mind the + and - markings. The capacitor is also polarized. Electrolytics are usually...

Sure, post that too.

Well, after studying the pictures I can now tell you a few things about the display that I know from my work experience. These things may or may not help you but I hope they do. First, looking at the full view of the back of the unit, the single black and two pink wires at the bottom right are...

Ah, this thing: http://www.millenniumvisuals.com/silentmessenger.php http://www.millenniumvisuals.com/images/solar/SilentII.png That's probably a proprietary interface. You might be able to work it out experimentally, if you're careful; but the chances of anyone here knowing offhand is...

Why is all that information scratched off the board? That's stuff you probably need to figure out what it is. It's certainly stuff I would need in order to identify it.

Except they really are all three-word quotes. A contraction is one word regardless of how many words it is formed from. Shouldn't've, for example, is only one word.

No, but if everyone turns their power back on at the same time, that might cause momentary outages as systems switch over to handle the sudden demand.

DaaaaaaAAAAAAAd! Lisa's touching me!

...Google unsafe images. :wink:

Molds, fungi and bacteria do not do well on butter because it's nearly pure fat with little moisture. The occasional addition of salt makes it even less palatable to microorganisms. It is likely to be still entirely edible, if rather rancid.

Assuming the wire stays consistent, the resistance increases linearly with length. If the resistance of a transmission wire is 1 ohm per 1000/ft, then the wire to a town 100 km away will be 100 ohms. On the other hand, by inspection of I2R, you can see the watts losses increase with the square...

I found a discussion of thirteen-month calandars in which the figure in the OP falls naturally out of the conversation: http://www.nabble.com/Re:-5515-Year-Luni-Solar-Cycle-p20917812.html

Education only goes so far. You can NOT force someone to learn something. You can force them to go to school, you can force them to sit through classes, you can even force them to repeat grades until they pass (do they even still do that anymore?) but you can NOT force them to learn. Or if...
