Testosterone does not cause assholish-ness, per se, so much as it exacerbates it.

Oh, so kind of like alcohol then.

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.

Only if you're really really lucky.

If there is true consensus about global warming, then science should be inviting opposing thought - not trying to stifle the discussion like a dictator.

But what if the opposing "thought" you're inviting is simply a bunch of specious reasoning debunked a long time ago? Repeated over and over. To the point that you realize that the ones doing the arguing have no interest whatsoever in any kind of objective truth. How long should you be inviting it then? How long do you pretend they deserve respect?

But if there is no difference between ball designs then why do we never see shots like these anymore?

It turns our that most people get the Paleo diet wrong. The diets of these people would differ wildly depending on the land they occupied.

For many of the myths espoused on what the Paleo diet was see here.

And really, 640 kg of unused plutonium ought to be enough for anybody.

Should that be considered a disability?

We don't need more web programming languages. Just one good one.

...and we are indeed the first who will learn a lot of lessons as we swarm across the galaxy once we figure out how to get off this damn rock.

You know, I've heard this attitude many times before, and I just don't get it. The Earth is beautiful. We've evolved to see it as beautiful, and yet people still aren't able to enjoy they great things they have right here. Protip: if you can't be happy here on Earth then you're incapable of finding happiness no matter where you go.

It's true that the GP is just representing one interpretation. Just thought I'd throw out my favorite "interpretation", (objective collapse theory) as it doesn't seem to get much love. No multiple worlds. No living-dead cats.

Also, instead of thinking of things being fundamentally composed of objects that are sort of both waves and particles I find it easier to picture them all as waves that only occasionally act as particles under the right conditions. This seems counter-intuitive since most of the world we experience is a result of these interactions that make them appear as particles. But it makes it a lot easier when picturing how things work with QFT and the difference between virtual and non-virtual "particles".

Actually, this experiment makes a pretty good case that special and general relativity are a demonstrated facts. Unless there's some philosophical hair-splitting in the definitions I missed.

Well then I guess I'll just have to take your word for it Mister 914043. ;)

You know, I'd like to think there was a time when the majority of Slashdot users could cheerfully take on writing modules for the Linux kernel or *gasp* just code in C.

I know exactly how to use spreadsheets properly. Just don't.
