Uncertain Dots 16

For the sixteenth episode of Uncertain Dots, we decided to bring in some guests, Andy Rundquist and Kelly O’Shea for a conversation about standards-based grading. This came up because I’m playing around with this using the same tiered scheme I talked about back in January. This was a fun conversation, and some interesting ideas came… Continue reading Uncertain Dots 16

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

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

Uncertain Dots, Episode 12

Back yard of Chateau Steelypips, April 16, 2014.

The last couple of days have been ridiculously hectic, but Rhett and I did manage to record another episode of Uncertain Dots, our twelfth: This time out, we talk about labs, undergrad research, kids doing chores, weather, student course evaluations, and I didn’t really rant about superheroes. Relevant to the weather thing, I offer the… Continue reading Uncertain Dots, Episode 12

Uncertain Dots, Episode 11

We took a week off last week because Rhett was away on a Secret Mission, but we’re back and better than ever this week. More uncertain! More dotty! Or something! Topics for this week include oblique references to Rhett’s mission, some discussion of the Geocentric Janeway debacle, good and bad places to have a conference,… Continue reading Uncertain Dots, Episode 11

Uncertain Dots, Episode A

In which we hit double digits, in base ten, anyway. This was mostly about teaching stuff, because I’m between terms, in that weird reflect-on-the-last term/ prep-for-the-next-term space. With a digression about training wheels, which are good as an analogy, but less good for actually learning to ride a bike…

Uncertain Dots, Episode 9

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… Continue reading Uncertain Dots, Episode 9
