Over at Five Thirty Eight, Walt Hickey has a piece about cheerleading as a sport and injury rates, which is both a nice look at the way to use stats to measure the real danger level of an activity, and the sort of small details that can be teased out. The piece includes a table […]
So, there was this big story in cosmology the other day– Tom Levenson’s write-up is very nice— which has been hailed as one of the greatest discoveries since the last greatest discovery, blah, blah, blah. And now that a few days have passed, we’re starting to see the inevitable backlash, ranging from detailed technical analyses […]
In which Rhett and I chat about the hot new discovery of primordial gravitational waves (maybe) very briefly before segueing into talking about LIGO, and Cosmos, and why “theory” is a terrible word, and the memorization of constants, and standardized tests, and time-lapse videos. You know, as one does. Miscellaneous items: — I’m a little […]
In the previous post about luge, I mentioned that there was one thing that came up when Rhett and I were talking about this, namely why there are differences in times between racers. The toy physics model I set up last time suggests that the difference between riders is only a matter of aerodynamics– two […]
In the Uncertain Dots hangout the other day, Rhett and I went off on a tangent about the physics of the Olympics, specifically the luge. If you’re not familiar with this, it’s basically psycho sledding: people riding tiny little sleds down a curved track at 80mph. The “featured image” above shows Erin Hamlin of the […]
Topping the looooong list of things I would give a full ResearchBlogging write-up if I had time is this new paper on a ultra-cold atom realization of “Dirac Monopoles”. This is really cool stuff, but there are a lot of intricacies that I don’t fully understand, so writing it up isn’t a simple matter. The […]
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 […]
There was a great big New York Times article on women in science this week, which prompted no end of discussion. (I also highly recommend Bee’s response at Backreaction.) It’s built around the personal story of the author, Eileen Pollack, a physics major at Yale who decided not to go to grad school, and her […]
One of the great things about “Fermi Problems” is that there are multiple ways of attacking them. So, for example, when considering the death ray plot yesterday, I used medical devices as an example system to assess the plausibility of the plot, while Physics Buzz talked total energy. But those aren’t the only ways to […]
One bad thing about SteelyKid’s preschool graduation yesterday was that it drained my phone battery, causing me to miss an interview request from a local TV station looking for somebody to talk about a a couple of local guys arrested for a plot to build a “death ray” from X-ray components. This is pretty far […]
