Uncertain Dots 19

In which our hangout turns nineteen; we may need to look into a special guest for the 20th, or something. Or maybe save guest stars for the one after that, when it can drink. Anyway, Rhett and I chat about grading, lab reports, why Excel sucks, and an online experiment that we really ought to…

Uncertain Dots 18

In which our series of Google hangouts becomes old enough to vote and buy cigarettes– but not drink! Miscellaneous things mentioned in this: – My forthcoming book at Amazon and Barnes and Noble. I turned in the copyedits and figures a week or so ago, and cashed an advance check today, so it’s definitely going…

Uncertain Dots 17

After a bit of a hiatus because of scheduling issues, Rhett and I are back to talk about… stuff. Mostly summer classes, World Cup soccer, and Twitter. Also, how we’ve each gotten a blog comment from Neil deGrasse Tyson. Miscellaneous links: – My long-ago book review and Rhett’s more recent complaint about Cosmos, where we…

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…

Uncertain Dots 15

Rhett and I did the 15th episode of our Uncertain Dots hangout yesterday, commenting on a discussion started by Casey Rutherford about what we would like students coming into college physics to know. We had a slight difference of opinion about physics content, but agreed about the importance of algebra (which is like sunscreen). I…

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…

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…

Uncertain Dots, Episode 12

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…

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,…

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…
