Uncertain Dots 14

Another week, another hangout with Rhett. In which we actually fielded a couple of questions from readers on Twitter, about the reason for inertia and a kind of meta-question. More audience questions would, of course, be welcome. A couple of links to things that came up: Mach’s Principle, a past attempt to explain the origin… Continue reading Uncertain Dots 14

What I’m Doing This August: Nordita Workshop for Science Writers

I’ve been setting up schedules with my summer research students lately, and the main constraint we’re facing with that is that I’m going to spend most of August in Europe. Part of this is pure vacation– Kate and I are going to the UK for a couple of weeks. Part of it is the World… Continue reading What I’m Doing This August: Nordita Workshop for Science Writers

Cosmos and the Sideburns

Last night’s episode of the Cosmos reboot focused on one of the three physicists whose pictures Einstein kept in his office: Michael Faraday. I’m a big fan of Faraday, who famously started his career as a bookbinder’s apprentice reading the books brought into the shop, and ended as one of the greatest experimental physicists of… Continue reading Cosmos and the Sideburns

Why Is Girls’ Soccer So Dangerous?

Table from 538 article about injury rates in sports; slightly scaled down to fit better on this blog.

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… Continue reading Why Is Girls’ Soccer So Dangerous?

“Gen Ed” Relativity: Pondering Books

Poster advertising next fall's "gen ed" class on relativity.

This coming fall term, I’ll be teaching Astronomy 052, “Relativity, Black Holes, and Quasars,” because the guy who has traditionally taught it (a radio astronomer who studies active galactic nuclei) has to do other courses instead. But I said “Well, hell, I’ve written a popular audience book explaining relativity. I can teach that.” And since… Continue reading “Gen Ed” Relativity: Pondering Books

On “Excessive Technical Detail”

I’ve seen a few links passed around to this Tom Siegfried post about science literacy, which is mostly a familiar story about how polls show most Americans giving incorrect answers to science questions. The sort of stuff you find in the NSF’s Science and Engineering Indicators report. What’s getting the social-media attention, though, is this… Continue reading On “Excessive Technical Detail”

Uncertain Dots, Lucky Number 13

We had a couple of weeks of unplanned hiatus due to sick kids and day care closures, so the superstitious among you might’ve thought we would never get to the 13th episode of Encertain Dots. Rhett and I are scientists, though, so we powered through: Given the time of year, this is mostly about end-of-academic-year… Continue reading Uncertain Dots, Lucky Number 13
