Tom Brady and the Ideal Gas Law: Physics of Deflategate

The experimental pressure measurements, with one of the cold footballs.

So, as mentioned yesterday, I got an email asking me about the weird scandal involving the Patriots and underinflated footballs, so I wrote a piece for the Conversation on the subject. since a few people had beaten me to citations of the Ideal Gas Law, though, I decided to bring my own particular set of… Continue reading Tom Brady and the Ideal Gas Law: Physics of Deflategate

Football Physics and the Science of Deflate-gate

One of the cool things about working at Union is that the Communications office gets media requests looking for people to comment on current events, which sometimes get forwarded to me. Yesterday was one of those days, with a request for a scientist to comment on the bizarre sports scandal surrounding the deflated footballs used… Continue reading Football Physics and the Science of Deflate-gate

Thermal Thursday: How Good Is My Mug?

Thermal image of my metal water bottle (left) and my insulated coffee mug, both half-full with hot water. Taken with a Seek Thermal camera on my Android phone.

One of my favorite Christmas presents this year was a Seek Thermal camera to use with my Android phone. This allows for a lot of idle physics-y fun, taking pictures of things in thermal mode. One idea I had was to do a sort of follow-up to the test of my insulated mug that I… Continue reading Thermal Thursday: How Good Is My Mug?

Hiring Completed

Having made several mentions here of the two tenure-track faculty positions we were trying to fill, I feel like I ought to at least note the completion of the search. As of last Friday, all the papers have been signed with properly dotted i’s and crossed t’s, and we have two new tenure-track assistant professors… Continue reading Hiring Completed

Science Stories: One-Shots

The "Valentine's Day Monopole" signal.

(When I launched the Advent Calendar of Science Stories series back in December, I had a few things in mind, but wasn’t sure I’d get through 24 days. In the end, I had more than enough material, and in fact didn’t end up using a few of my original ideas. So I’ll do a few… Continue reading Science Stories: One-Shots

Semi-Competent Astrophotography and Sidereal Days

PowerPoint slide on the difference between solar and sidereal days.

I’m teaching my “Brief History of Timekeeping” class again this term, and as always, I’m tweaking things a bit. This is one of our “Sophomore Research Seminar” courses, intended to introduce students to academic research, so it’s not specifically a physics class, but I’m choosing to take the statements about research outside the student’s field… Continue reading Semi-Competent Astrophotography and Sidereal Days

The Sun Is Red Because The Sky Is Blue

My phone camera couldn't handle sunrise, so here's The Pip at his big sister's soccer practice around sunset.

SteelyKid missed the bus this morning– she was dressed and ready, but I was talking to Kate, and if there isn’t a person at the end of the driveway when the bus comes around the corner, they won’t stop. So I drove her over to school myself (which is faster, anyway). The GE research lab… Continue reading The Sun Is Red Because The Sky Is Blue

Some Follow-Up on Teaching

Yesterday’s Open Letter to Neil deGrasse Tyson struck a chord with a lot of people, and has spread a good distance on social media, which is gratifying. Given the delocalized nature of modern social media, though, it means I’m having essentially the same argument in five different places via different platforms. In the interest of… Continue reading Some Follow-Up on Teaching
