It’s been a month since the last links dump of posts from Forbes, though, really, I took a couple of weeks off there, so it’s been less than that in terms of active blogging time. But I’ve put up a bunch of stuff in July, so here are some links: — The Physics Of Ancient…

It’s one of those days where none of the stuff I probably ought to be writing seems even slightly appealing, so instead I’m going to do something frivolous and morale-boosting, namely think out loud about an imaginary course. Despite being on sabbatical, I do still check my work email, and have caught the edges of…

Attempted Mpemba Effect

One of my favorite modern tales of scientific discovery is the Mpemba Effect, named after Erasto Mpemba, a schoolboy in Tanzania who noticed while making ice cream that hot mix put in the freezer solidified faster than cold. This counter-intuitive result has been replicated a bunch of times, and physicists and chemists continue to debate…

165/366: Wintry Science

It was bitterly cold over the weekend here in the Northeast, with daytime high temepratures in the single digits Fahrenheit. This has little to recommend it in terms of, you know, leaving the house, but it did provide an opportunity to try some SCIENCE! Unfortunately, I left the notepad with the data (such as it…

152/366: Fun With Motion Blur

This one was a whole bunch of work for one smallish shot… So, in past rounds of “science-y things with my fancy camera,” I looked at the effect of ISO settings and apertures. This time out, I wanted to look at something moving, and the way that it blurs with increasing exposure time. My initial…

One of the things about being a physicist that makes it tough to have any sensible work-life balance is that I’m constantly seeing little things and thinking “Oooh! Physics!” then getting distracted from what I’m actually supposed to be doing. Take, for example, our bathroom sink. I have noticed, from time to time, a weird…

The Exotic Physics of an Ordinary Morning

A couple of weeks ago, I gave a talk at TEDxAlbany on how quantum physics manifests in everyday life. I posted the approximate text back then, but TEDx has now put up the video: So, if you’ve been wondering what it sounded like live, well, now you can see…

So, yesterday was my big TEDxAlbany talk. I was the first speaker scheduled, probably because I gave them the title “The Exotic Physics of an Ordinary Morning,” so it seemed appropriate to have me talking while people were still eating breakfast… The abstract I wrote when I did the proposal mentions both quantum physics and…

Rotational Motion of a Bouncing Football

I followed up my ranty-y post about “Sports Science” with an experimental investigation over at Forbes, tossing a football around on the deck out back and then doing video analysis of the bounces. This provided a wealth of data, much of it not really appropriate for over there, but good for a physics post or…

Sports Technobabble

Over in Twitter-land, Rhett Allain drew my attention to this “Sports Science” clip from ESPN, about a wild 4th-and-25 play in the Arkansas-Ole Miss game. This is nominally because I’ve been writing about big hits and bouncing balls over at Forbes, but really, I think Rhett’s just working on a “misery loves company” theory, here:…
