Huh. I really did love his earlier books. And while he may of gone off the deep end sometimes, or may have been wrong headed at times, he did a lot to keep the subject of science front and center in most of his works of fiction. Ultimately, a good thing...

Uncertainty may make you uncomfortable. Certainty makes you ridiculous.

If the probability of A>0 and the probability of B<1, is A more probable than B?

I'm no more a mathematician than Kent Hovind is a paleontologist, but it seems to me that this question cannot be answered with the limited information given.

The only differences between A and B are at the extremes. No matter how many decimals you go out to, both have the same chance of being 0.513783654 (for example). So, because A will never be 0 and A has some chance of being 1.0, while B has no chance of being 1.0 and has some chance of being 0, then it seems to me that A is precisely 10-n more probable than B, where n is the number of decimals you're working with. Well, that tells us that the average of all possible values of A is slightly higher than the average of all possible values of B, but as n approaches infinity, the difference approaches zero.

Makes sense. Thanks.

So I've been playing Peggle Deluxe on-and-off for the past year or so, and finally, tonight, have gained the rank of "EXTREME GRAND MASTER OF PEGGLE." So I don't have to play that game any more.

Unfortunately, my wife helpfully downloaded Peggle Nights a couple of weeks ago, and I just stumbled across the original Peggle while looking for the above link. So much to do!

Do light waves really look like this:

I mean, as a photon zips along at 3*108, does it also sort of move up and down like in the picture?

If so, well, how? What tells a red wavelength to move as it does? And doesn't it seem like a rather inefficient movement? Why doesn't the photon just move along in a straight line?

And if not, then why do we talk about wavelengths?

No. Electromagnetic radiation oscillates in the magnitude of the electric and magnetic fields it carries with it. The wavelength is the distance the photon travels between two subsequent peaks of the magnitude of those fields.

Also, there's a 90 angle between the electric- and the magnetic field.

So I captured this screenshot from my Yahoo mail account. The lead article is about Hillary Clinton potentially filling a cabinet position. Only...that isn't a photo of Hillary. Do you think somebody was having a laugh or does the former First Lady really look that much like Elton John?




Edited to add: Glad I screen-capped it, because just after posting this the image was changed to this:

...and I had to look up the second amendment on wikipedia to get the point. However, it was a very good point.
