We've been a bit crazed this week plugging the new book, as authors are wont to do. I chatted with Chris Mooney on Mother Jones' Inquiring Minds podcast on how the science of self is exploring not just who we are, but if we are. Also, I played guest instead of host this week on Virtually Speaking Science, chatting with Alan Boyle about the self and the psychology of "selfies."

"Selfies" were on everyone's mind this week thanks to Ellen Degeneres' infamous Oscar tweet of a star-studded selfie that quickly became the most tweeted photo ever. But apparently Our Obsession With Online Quizzes Comes From Fear, Not Narcissism.

Speaking of the Oscars, NASA Toasted Gravity -- which walked away with several of the coveted statues, including a Best Director win for Cuaron -- with an Amazing Series of Real-Life Images from Space. Related: have you ever wondered how much would Oscar made out of solid gold would be worth? The answer: More money than anything ever. Also: Revisiting The Art of the Score: The Mind, Music, and Moving Images.

This week also featured the much-anticipated Cosmos reboot's premiere in Los Angeles, because what's more entertaining than science? We'll be watching when it airs on Sunday! Also, actress and science fan Taryn O'Neill explains why COSMOS matters, to Hollywood as well as to science.

Also, Katherine Freese provided thoughtful commentary with a guest post over at Preposterous Universe. The next big break in understanding dark matter may come from Japan's Astro-H satellite, due next year.

Neat post on public knowledge of atomic physics, 1941:

"One of the biggest misconceptions that people have about the Manhattan Project is that prior to Hiroshima, all knowledge of atomic energy and nuclear fission was secret — that the very idea of nuclear weapons was unthought except inside classified circles. ... The reality is, as always, more complicated, and more interesting. Fission had been discovered in 1939, chain reactions were talked about publicly a few months later, and by the early 1940s the subject of atomic power and atomic bombs had become a staple of science journalists and science fiction authors."

Related: Jason Rosenhouse shared his thoughts on Sean Carroll's debate with William Lane Craig.

Theists have to face that fact no less than atheists."

How to Talk to a Mathematician. "At least rocket scientists and neurosurgeons can point to concrete objects that they work with—spaceships! Brains! By contrast, mathematicians work with pure ideas.
