It would have been nice if they mentioned that as a result of Cantor's diagonalization argument (the argument outlined in the video) that we call sets where the lines can be drawn "countable" and those where the lines can't be drawn "uncountable." It was a pretty good introduction nonetheless.

I almost never use my iPhone's flash; the HDR mode covers probably 90% of situations where you would traditionally use flash and produces much more natural shots.

Wow, I need to have my coffee earlier. "Site"

I love today's XKCD, but I have to admit, it bothers a me a bit that Giz is writing about it when a subset of the writers on this sight refuse to adhere to the principle outlined in the comic. Nevertheless, the majority are great.

Yes, you're absolutely right. That number is likely take from the SPC page (spc.noaa.gov), which is always riddled with redundant and false reports until NWS survey teams can complete their work. That being said, I really don't appreciate the tone of this article. Harold Brooks is an incredibly talented…

Because the collision would have crumpled 2 or 3 of the first water tight compartments, of which 3 of the first 4 could flood without causing the ship to sink. The grazing blow of the iceberg opened 6 of the compartments.

I don't mean to nitpick, but a lot of this information is blatantly wrong. As someone already pointed out, the Titanic struck the iceberg at 11:40 p.m. on April 14 and sank 2:20 a.m. on April 15. The iceberg did not "rip open a hole;" it made a series of very small gashes. The ship did not attempt to sail on; a…

I agree. Given the heat issues (or near-issues, depending on your perspective), I wonder if they opted not to up the wattage because it would add to the pre-existing issue and being that the maximum operating temperature is already near the limit of the average user's tolerable range, it might have pushed it over the…

That really bugged me too. Being a classical composer, I was super excited by this, then I saw that they only used classical music and thus, one could not draw any conclusions about the relative utility of classical music with regards to other genres (except that it is at least, but not necessarily more useful in…

Am I the only one wondering why those phones are displaying different times and dates?

In fairness, I didn't read the actually study, but given what's written here, it kind of seems like they're jumping the gun a bit to me. Isn't there a correlation/causation issue lurking?

Heh, when I was a kid, I had a bad habit of sticking things in my ears and went through the exact same ordeal. I had a small magnet and two pieces of envelope thickness paper stuck in my ear and a non-ENT nurse spent 15 minutes trying to dig them out with a pair of tweezers, which was absolute agony. It took the ENT…

Mister_Roboto and @bigbox: thanks for the help!

I'm just curious though... even if there was no return train or it was unavailable to him, why not follow the track back in the other direction? The article says "hours later," so if that's true, it wouldn't be an impossible task. I think there's some missing details too...

Do I think I'd have any trouble getting this on my sweet 20 y/o gelding? No. Do I think you'd have to be out of your mind to try to put it on a hot 2 y/o stud at the track (like this is designed for)? Yes. That being said, it's not particularly hard to put on. Here's how you would: Depending on how stretchy it…

That we exploit an innocent and helpless creature for a product that has a readily available and viable synthetic alternative? Yes, that does make me sad. Does that exclude other things from making me sad? No. What's your point? @EndangeredSpeciesM, it's an extension of the fact that the existence of horse meat makes…

What a sad thought that this sort of practice still exists.

[www.amazon.com] my friend.

The problem is your definition of "exists" and partially of "observed." To "exist," in this context, means to be in a certain state with probability one. Without "observing" a particle, it exists in multiple states with corresponding probabilities, altogether which sum to one. Of course, to know that the particle…

How environmentally safe is this, though? I'm not saying coating a tree in this stuff is automatically bad, but my first instinct says so.
