Beside that, special relativity has been corroborated again and again, tachyons are shown to be unstable due to their imaginary mass component, and physics as we know it simply doesn't hold up well in the presence of closed spacelike paths.
This isn't to say FTL travel is impossible. *Maybe* some way exists that gets around these huge obstacles, but when they say there's no known way it could work, it's not for lack of imagination.
Ah, okay. Right. So then I guess different waveforms represent different superpositions? What is the basis? The only one I can imagine is complex exponentials, but the closest thing those have to a "location" is phase, so I don't see how they could exhibit a propagation velocity. Maybe I'm just going to have to read a book about this.
"Spooky action at a distance" happens faster than light, but only *after* the entanglement has been set up and the partner particle has been transmitted at light speed or slower. And even then, no information can actually be sent by this method.
I'm not a big fan of Terraria, but I do feel it's different enough from Minecraft that it deserves to be its own game. Its RPG-ish sense of progression is much stronger than Minecraft's and its sidescrolling style is not to be overlooked. I can totally imagine Terraria being born from someone looking at Minecraft and wishing it had gone in a different direction.
We're missing the island of stability and we don't know how to hit it yet. As the article you link states, "The manufacturing of nuclei in the island of stability proves to be very difficult, because the nuclei available as starting materials do not deliver the necessary sum of neutrons."
Why must they repeatedly conflate partitions, partition counts, and sequences of partition counts? I can't tell what they're actually saying. First the article reads, "To be slightly more technical, from Ken Ono and Kathrin Bringman, 'A partition of a non-negative integer n is a non-increasing sequence of positive integers whose sum is n.' The concept is straight forward, but how to obtain these partition numbers, in general, is actually no trivial matter."
Then later, "...a finite, algebraic formula for partition numbers thanks to the discovering that partitions are fractal." Well do they mean partitions are fractal, or partition counts are fractal?
Another article at eScienceCommons (another post here links to it) quotes Ono: “We prove that partition numbers are ‘fractal’ for every prime." How can a number be fractal? Or does he mean the sequence over primes is fractal? WTF?
Ken Ono says in the press release, "I can take any number, plug it into P, and instantly calculate the partitions of that number." Does he mean the partitions themselves or the partition count?
You'd think detail-oriented professionals would be more precise in their wording.
4e18 seconds of thrust??? The halfway point is only 6e9 seconds out. That gives you 6e6 m/s delta-v. Still prohibitive, but if the journey is 6000 years you have exp(2e5/3e5) ~= 2.
Genetics and evolution are tied up together. Evolutionary theory has led to insights in genetics and vice versa. Any understanding based on genetics has evolutionary theory to thank as well.
"a common calculation using spectral analysis and data compression" should read "a common calculation used in spectral analysis and data compression" instead.
Dr. Kuchera-Morin is primarily an artist. She's truly interested in doing what she says in her TED talk, which is bringing all disciplines together to share knowledge, but she originally imagined the Allosphere as the ultimate multimedia theater. The artistic computer music community (especially the people in the MAT program, which she directs) are heavily into spatialization using a large number of loudspeakers and the Allosphere will facilitate such art presentations. If scientists can get some use out of it, all the better, but I sense (I really don't know) that she pitched the Allosphere to UCSB's world-renowned physics department in order to get funding. She's been talking about the Allosphere since the founding of the MAT program (1999 I think), and I still don't know how she did it.
People don't want a scientific definition anyway. That would deprive them of the sense of righteousness they feel when their hunches lead them to unleash their fear and anger on the nearest available target.

I have one question: Will the sequel also be monotonously brown?
Between Fallout 3, New Vegas, the caves in Oblivion, and Borderlands, I've had just about all the grey and brown I can stand.
The test set represented 18000 users. The probability of flipping 18000 coins and getting 65.9% heads or more is 8.1e-405.
Light has momentum, not mass.

What does "single photon with controllable waveforms" mean? I thought photons were all sinusoids under a gaussian envelope.

I'm an American and I sympathize with you wholeheartedly.

Redundant? Who said this before me?
"a common calculation using spectral analysis and data compression" should read "a common calculation used in spectral analysis and data compression" instead.
I thought the title of the book might be "Fucking and Punching" but I guess not.
What about the mom? Giving birth to a frisbee must have hurt.
Let this post be a lesson. If a blind guy can spell perfectly on the Internet, so can the rest of you slobs!
It probably just means the spacetime metric has two positive terms and two negative terms. Instead of
ds^2 = dx^2 + dy^2 + dz^2 - dt^2
you have
ds^2 = dx^2 + dy^2 - dt^2 - du^2
Can a real physicist speak to this?
Eliza: What makes you think what I've just said is one of the most insanely idiotic things you have ever heard?
How about the stock exchange? People buy and sell all kinds of commodities there without ever using them.
Actually, we do it because it's haaaahhhd.

Haha, yes, I fell for it. Would you believe the "I haven't had my coffee yet" defense?
Well, that's the end of that.
