Imagine Science Film Festival

Both Physics Buzz and the X-Change Files are noting the Imagine Science Film Festival starting tomorrow in New York City. As the Buzz notes: This is only the film festival’s second year, but it’s already attracted the attention of major sponsors. Last year the journal Nature co-sponsored the festival, and this year the American Association… Continue reading Imagine Science Film Festival

Silly Poll: Scary Creatures

SteelyKid has a fever, and can’t go to day care, so I’m staying home with her. This pretty much rules out significant serious blogging, so here’s a poll to keep you amused: Which of these threats is most threatening?(survey) Choose only one.

Adventures in OA

The abbreviation here has a double meaning– both “Open Access” and “Operator Algebra.” In my Quantum Optics class yesterday, I was talking about how to describe “coherent states” in the photon number state formalism. Coherent states are the best quantum description of a classical light field– something like a laser, which behaves very much as… Continue reading Adventures in OA

Many Worlds, Many Comics

The Digital Cuttlefish looks at the Archie comics, and waxes poetic: Two paths play out in a comic book, When Archie walks down memory lane “The road not taken” is the hook; So now, the writers take a look And re-write Archie’s life again, This time with Betty as his bride; Veronica the woman spurned,… Continue reading Many Worlds, Many Comics

What the Pope’s Astronomer Thinks

Over at Physics and Physicists, ZapperZ notes a fairly useless interview with Guy Consolmagno, and suggests some alternative questions: 1. How old do you estimate the universe to be based not only on your observation, but also the consensus among astronomers? Would this be contrary to the biblical interpretation on the age of the universe?… Continue reading What the Pope’s Astronomer Thinks

The odd thing is that none of these trips are book-publicity junkets– they’re all basically professional-type appearances, several of them taking place before How to Teach Physics to Your Dog hits stores on December 22. My… Continue reading Where I’m Going to Be

Dorky Poll: Photon Operators

Prompted by working on lecture notes for Quantum Optics last night, a Dorky Poll about the mathematical formalism of photon number states What’s your favorite photon operator?(polls) I know it’s hard to pick, but choose only one.
