Math and Science Are Not Cleanly Separable

One of the hot topics of the moment is the E. O. Wilson op-ed lamenting the way math scares students off from science, and downplaying the need for mathematical skill (this is not news, really– he said more or less the same thing a few years ago, but the Wall Street Journal published it to… Continue reading Math and Science Are Not Cleanly Separable

The Problems of Science Media Are Not Unique

On Twitter and blogs, we’re having another round of complaints about sensationalism and hype in science stories– Matthew Francis and Gabrielle Rabinowitz are the latest to cross my social media feeds. I’ve also seen some stories recently (that I’m too lazy to dig up) complaining about the latest Higgs Boson stuff, and I’m sure if… Continue reading The Problems of Science Media Are Not Unique

How Do You Make Negative Temperatures, Anyway?

Part of Figure 1 from the arxiv preprint of the paper discussed in the post.

Last week’s post talked about the general idea of negative temperature, with reference to this much-talked-about Science paper (which also comes in a free arxiv version from which the figures used here are taken). I didn’t go into the details of how they made a negative temperature gas, though, and as it’s both very clever… Continue reading How Do You Make Negative Temperatures, Anyway?

What Does “Negative Temperature” Mean, Anyway?

Part of Figure 1 from the arxiv preprint of the paper discussed in the post.

The most talked-about physics paper last week was probably Negative Absolute Temperature for Motional Degrees of Freedom (that link goes to the paywalled journal; there’s also a free arxiv preprint from which the above figure is taken). It’s a catchy but easily misinterpreted title– Negative absolute temperature! Below Absolute Zero! Thermodynamics is wrong!– that obscures… Continue reading What Does “Negative Temperature” Mean, Anyway?

Congratulations to Roth and Shapley and John Novak

The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel has just been announced, and goes to Alvin E. Roth and Lloyd S. Shapley “for the theory of stable allocations and the practice of market design.” I know basically nothing about these guys, but I assume they’ve earned their Sveriges Riksbank Prize, so… Continue reading Congratulations to Roth and Shapley and John Novak

What’s So Interesting About Single Quantum Systems? Physics Nobel 2012

In which we do a little imaginary Q&A to explain the significance of Tuesday’s Nobel Prize to Dave Wineland and Serge Haroche. ———— I did a quick post Tuesday morning noting that the latest Nobel Prize in Physics was awarded to two big names from my corner of the field. This would’ve been a great… Continue reading What’s So Interesting About Single Quantum Systems? Physics Nobel 2012

Congratulations to Dave Wineland, Serge Haroche, and KSC

The 2012 Nobel Prize in Physics was announced this morning, going to Serge Haroche and Dave Wineland, “for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems”. This isn’t a pair that was getting much love from the prognosticators, but they’re an excellent choice. And, in fact, commenter KSC correctly picked Wineland… Continue reading Congratulations to Dave Wineland, Serge Haroche, and KSC

Simulating Wires with Atoms and Light: “Conduction of Ultracold Fermions Through a Mesoscopic Channel”

Top: the atom cloud; Bottom: false-color image with orange indicating an excess of atoms and green a lack.

So, it’s been a while, but let’s see if we can’t hit the ground running with a good physics post. There have been a few notable physics events since I went on hiatus, but for a return to physics ResearchBlogging, we’ll go with something near and dear to my heart, ultracold atoms. Specifically, this Science… Continue reading Simulating Wires with Atoms and Light: “Conduction of Ultracold Fermions Through a Mesoscopic Channel”
