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...

Debunked hoax.

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

Of course, the failure of science to observe an event can also indicate the event doesn't occur. The longer science goes without being able to observe an event which should be observable, the less likely the event is to ever occur.

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...

CO2 is deadly, too. Just in a different way.

First of all, punishment has a particular meaning which is NOT covered by any of the examples you have here. It does not simply mean "do something bad to someone." Secondly, there are plenty of laws which don't "punish" anyone; who suffers the "punishment" when laws against, for example, car...

Depends. Did you read your lease carefully? (7) There is no cause of action for a nuisance under Subsection (3) if the rental, lease, or 7 purchase agreement for the unit states in writing that: 8 (a) smoking is allowed in other units and that tobacco smoke from those units...

What does it mean when I tell you, for example, that the Earth has a diameter of 7400 miles and it makes one revolution in 24 hours? Can't you relate that to an angular velocity with simple arithmetic?

The figures in my post are given as angular velocity, albeit somehwat indirectly.

It may not hae been initially clear, but there's a link in my prior post which answers your op-amp question. An op-amp is an amplifier which has the following characteristics: EDIT: I've bolded an error I just noticed in the previous link. Everything else looks okay, but I'll provide an...

Instead of trying to understand op-amps as the sum of their parts, youy're probably beetter off learning op-amp theory as a fundamental unit. Think of an op-amp as a black box; you don't need to know what's inside in order to understand it, you need only know how it behaves given specific...

Sure. Start by reviewing the truth tables for the gates in question.

You want to think about that for a minute? If they're a group, either the nonsmokers already expect to be in a smoking environment or the smokers already expect to be in a nonsmoking one. Nobody's actually giving up anything.

In fact, lightining can travel as far as twenty miles through the air. One way or another, the lightning which sxtrikes your car will find its way out the bottom of the vehicle to ground. If nothing else, it wil jump the <12" gap between the bottom of the chassis and the ground below; the...

You don't need ferrite, you need an electrically conductive material. Ferrite is great for magnetic shielding, but is terrible for RF EMI. Try something like this: http://www.mgchemicals.com/products/841.html?PHPSESSID=d41c883dc3548ebc1362bc3c166c5db7 [Broken] Be sure you ground all of...

Is not. You just need a modern set of skills and tools. Lots of stuff is still perfectly fixable; the tricky part is getting the parts.

You know the Earth's diameter is about 7400 miles and rotates once in 24 hours. You also know the Earth's orbit averages about 93,000,000 miles and completes once every 365 days. Do the math and you tell me.

You know what? You're absolutely right; that was some weak sauce on my part. I'm embarassed to have put it out there and I thank you for rightfully tearing it to shreds. Usually, I think an argument over pretty well before I post it; this is why. I still say smoking is a right, however, if...

I don't know what the heck this is. Teach me to, y'know, sleep.

This is not correct. Lots of rights have restrictions. The right to vote has an age limit and residency requirements and in some cases, convicted felons cannot vote. Free speech has restrictions; you cannot shout "Fire!" in a crowded movied theater, for example. You have a right to smoke...

You were saying?

I don't mean I have to touch the energized conductors, silly. Just the equipment. Can't test it while it's off.

I have to; it's my job.

Bingo. I'm amazed that so many ostensibly intelligent people don't understand this very basic social concept.

Yes, that's likely illegal, too, depending on where I happen to be at the time. In any case, I do understand the point you are trying to make but unfortunately, it's invalid. See, smoking (in addition to being perfectly legal, with certain exceptions previously noted upthread) has, at least up...

And you should also understand that even given the above, a crystal won't just sit there and vibrate indefinitely at its mechanical resonance--it requires input to do so.

That would also be illegal; as a hazmat, asbestos requires special handling by EPA-licensed contractors.

Driving drunk is illegal and therefore undeserving of courtesy. Try again.

Yes, that is the overall tone of your posts thus far, intentional or not.

The system is broken as much because of self-righteous people like you as by rude smokers. I quit smoking 6 years ago.

Because if you want courtesy from smokers you have to give courtesy back. That's the way society works, whether you like it or not.

No, this is not a fact. This is garbage "science" with no basis in reality. The rest of your post just goes downhill from there and most of it was already answered in your other thread: https://www.physicsforums.com/showthread.php?t=335427

Abusive or nasty emails are unprofessional. Report her and forward copies of the emails to the appropriate administrators.

Nothing of the sort. Let's compare and contrast, shall we? Note the lack of UPPER CASE SHOUTING and multiple exclamation points! in the OP. Note the lack of insults ("you're disgusting...") and the complete disdain ("...go ahead kill yourself, you have my blessing.") Sorry, but there is...
