Hi ho, hi ho, it’s off to the March Meeting I go. To run and play, and talk all day, hi ho, hi ho, hi ho, hi ho.
Talks I will most likely be attending: these. Food I will be seeking out this. Exciting physics works I will be on the outlook for: here
Qubits, Qbits, qbits, qubits, q-bits, and light nanoseconds
Hurray! My letter to Physics Today along with a delightful response from N. David Mermin has been published. I particularly enjoyed Mermin’s closing line:
It may be quixotic (but certainly not Qxotic) to try to correct the spelling of an entire community, but I owe it my best shot. What else is retirement good for?
Sweet! Now I can check off from my list of things to do in life: “Get published in Physics Today over issues related to my literature degree.”
"I'm Never Getting Out of New Jersey"
A day in the life of a traveler. For your amusement?

Twins in Donut Space
Visiting Princeton, the American home to Albert Einstein, I’m reminded of one of my favorite “paradoxes” of special relativity. And, even more so, one of my favorite versions of this paradox which, when I first heard it, it blew my mind. What paradox is this of which I speak? The twin paradox of course! Really just the plain old twin paradox? No. Much better than that: the twin paradox in donut space!

This Side of Paradise
Quantum Algorithms and the Strange Nature of Quantum Theory
Over at Information Processing, the InfoProcessor talks about teaching Bell’s theorem:
I find that the hardest thing about teaching this material in class is that, after half a year of training students’ brains to think quantum mechanically, it is extremely difficult to get them to feel the weirdness of Bell’s theorem and spooky action. It all seems quite normal to them in the context of the course — they know how to calculate, and that’s just how quantum mechanics works!

The Same Title?
On the arxiv Friday:
arXiv:0802.4248
Title: Coexistence of qubit effects
Authors: Peter Stano, Daniel Reitzner, Teiko Heinosaari
Comments: A paper with identical title is being published on the arXiv simultaneously by Paul Busch and Heinz-Jurgen Schmidt. These authors solve the same problem independently with a different method.

Chosing the same title seems a bit strange to me. I mean simultaneous result posting happens quite frequently, but with the same title? But at least this answers a question I’ve always had which is whether the arxiv allows papers with the same title.
You Versus the Chimp
And they says humans are the smart ones:

Happy Leap Friday! For your enjoyment, some ferromagnetic fluids jiving to a piano piece:
Slandering Ants Anthropically
Another checkmark in front of the “antrhopic reasoning is whack”:
arXiv:0802.4121
Title: Ants are not Conscious
Authors: Russell K. Standish
Anthropic reasoning is a form of statistical reasoning based upon finding oneself a member of a particular reference class of conscious beings. By considering empirical distribution functions defined over animal life on Earth, we can deduce that the vast bulk of animal life is unlikely to be conscious. As a side effect of these deliberations, I also show that naturally occurring fragmentation/coalescence processes give rise to a power law distribution of fragment sizes, a previously unknown mechanism for generating power laws.
