Finding That There’s Nothing to Find

Luis Alvarez, Ahmed Fakhry, Jerry Anderson with the equipment for the Pyramid Project, from Wikipedia.

In 1967, a team of scientists hauled a big pile of gear– electronics, particle detectors, a giant slab of iron– into the burial chamber at the base of one of the pyramids at Giza. This sounds like a scene from a science fiction or fantasy novel– throw in the fact that their first attempt was… Continue reading Finding That There’s Nothing to Find

Individualists, Working Together

"The Individualistic Team" graphic from Physics Today, by Ricardo Heras.

An article titled “Individualism: The legacy of great physicists,” by Ricardo Heras. crossed my various social media feeds a half-dozen times on Tuesday, so I finally broke down and read it, and I’m puzzled. The argument is very straightforward– single-author publications used to be common, now they’re not, this might indicate a lack of truly… Continue reading Individualists, Working Together

One, Two, Many, Lots: Investigating the Start of Many-Body Physics

Part of Fig. 2 from the arxiv version of the paper by Wenz et al.

Two papers with a similar theme crossed my social media feeds in the last couple of days. You might think this is just a weird coincidence, but I’m choosing to take it as a sign to write about them for the blog. So, what are these papers, and what’s the theme? One is the final… Continue reading One, Two, Many, Lots: Investigating the Start of Many-Body Physics

On Private Science Funding

A couple of weeks back, DougT won this year’s Nobel betting pool, and requested a post on the subject of funding of wacky ieas: could you comment on this: http://www.space.com/22344-elon-musk-hyperloop-technology-revealed.html and the phenomenon of the uber-rich funding science in general. It seems to me that there used to be more private funding of science, and… Continue reading On Private Science Funding

Historical Physicist Halloween Costumes

Portrait of Isaac Newton circa 1689.

It’s that time of year again when people start thinking about Halloween costumes– SteelyKid is apparently planning to re-use her Peter Pan outfit from last year– and the conceptual costumes post from a while back has proved enduringly popular at this time of year. If you’re not into conceptual art, though, maybe some historical cosplay… Continue reading Historical Physicist Halloween Costumes

Free, As In Energy

Via social media, John Novak cashes in a Nobel Betting Pool win from a while back, asking: Please explain to me the relationship between energy, entropy, and free energy. Like you would explain it to a two year old child. Why? There is a statistical algorithm called Expectation Maximization which is often explained in terms… Continue reading Free, As In Energy

Sick Dude Day

Nothing that an Elmo shirt, a pacifier, and Jake and the Never Land Pirates can't fix.

The Pip has pinkeye. Again. This means he can’t go to day care for at least one day, which means I’m home with him for the morning, and Kate will tag in at lunchtime so I can go teach my class. This, in turn, means that you don’t get any substantive blogging today, because the… Continue reading Sick Dude Day

Quantum Erasure

A Mach-Zehnder interferometer.

When I posted congratulating the winner of this year’s Nobel betting pool, I received a gentle reminder in email that I’m a Bad Person and still haven’t done one of the posts I owe to the 2011 winners. Evan reminded me that he asked for something about the delayed-choice quantum eraser, so let’s talk about… Continue reading Quantum Erasure
