Ack! No. The 5.500000 has seven significant digits. The zeroes following the decimal point count since by convention it means that the measurement has been taken to be that precise.

10K probably has infinite significant figures as that's an expression of an exact running distance, not an estimate. The 3.4 miles is probably an estimate (I haven't heard any of any 3.4 mile standard runs - but then I'm not a runner), so it would have two significant figures. But even if 10K and 3.4 had infinite significant digits the number of decimal places you use for the answer would hinge on how precise of a number you use for the conversion between the two units.

You want equality? When may men have the right to bodily integrity? Or are you suggesting women should enjoy living with mutilated genitals as well for equality?

For the record, just about any feminist I've heard give an opinion on the subject has been against male circumcision as well.

It's impossible to tell whether or not an answer is "fallacy ridden garbage" if you don't bother to listen to it in the first place. Sure the answer could be crap, but if you don't bother evaluating it objectively just because you're assuming the established thinking is always crap then you aren't thinking critically.

Just adding my own simple, non-calculus solution, to the mix.

When the radius of the earth is r we have...
Length of string around earth = 2*pi*r
Length of string around earth and poodle evenly = 2*pi(r + poodle)

Subtract former from the latter and it's 2*pi*r + 2*pi*poodle - 2*pi*r, so just 2*pi*poodle more.

You can find a selection of pretty good movies they offer here. I ended up watching Dredd and was blown away - something I wouldn't have done if not for word of mouth. (So you're trying to tell me someone made another movie on Judge Dredd that's actually good?) And of course, sometimes the movies you at first don't recognize end up being the ones you love the most.

They built a pyramid, we havn't.

How can we tell them how to build it better, when we cant even achieve what they did 4000+ years ago? lol

But my point is it may be the only thing preventing us from achieving the same is an unwillingness to be blatantly immoral (not to mention finding a compelling reason to build one in the first place). If that's the case then, yeah, we might very well have grounds for telling the a better way to do the same thing. You never know. *shrug*

Electrons interfere with themselves, because the fluctuation (which is the electron) exists in the full region between the source and screen. The interference pattern is the same no matter how slowly (in terms of electron rate) you fire the electrons, so build up is not a concern.

And this is an important point. I'm not a physicist, but one thing that helped me understand this better is to consider firing a single electron (for example) at the two slits one at the time. It could be at the rate of one per minute, one hour or whatever.

Every electron that makes it through to the screen behind the two slits will hit it at a single point. Nothing unusual there. However, if you make a histogram on the screen based on how frequently each spot gets hit by an electron you'll see the interference pattern you'd expect from a wave being split in two from the two slits. So each electron is a wave that travels through both slits, not one or the other.

Some people claim that the UNIX learning curve is steep, but at least you only have to climb it once.
