some sports make the athletes beautiful by osmosis. soccer is like this. nearly every big American sport, however, is not
one of my favorite things about the winter olympics is when a skier or snowboarder blows my mind with athletic feats of daring that would literally kill regular folks. and then they remove their mask and are ALSO the Most Beautiful Person Alive

My original plan for today was to drive over to VT and do some skiing before the really bitter cold hit, but the temperature is on a steep dive and the wind gusts on the dog walk just now were incredibly unpleasant so I'll be doing something indoors...

Went out skiing this morning at a golf course, and I can not for the life of me figure out how people are making tracks that go for a significant distance on flat ground with one ski higher than the other.

We gotta get this in the Olympics now
During part of this we discussed Alpine Luge, which is an amazing sliding sport that sadly is not in the Olympics.
Anyway, here's what that looks like, with one of the greatest to ever doing it giving the demonstration down the track in Deutschnofen

Request for QC-type folks: I'm teaching Quantum Optics/ Quantum Information to Jr/Sr undergrads, and asking students to do research papers/ presentations. I would like to be able to point them toward some quantum algorithms sorts of things that I won't cover in class; what should I suggest?

First they came for Bill Belichick, and I went lol. Then they came for Robert Kraft, and once again I went lol.
From @theathletic.com: Robert Kraft, who owned the New England Patriots for each of their six Super Bowl wins, did not receive enough votes to be enshrined into the Pro Football Hall of Fame.
Bill Belichick was not elected into the hall either.

I would much rather live under the mayoralty of Mamdani, but Adams strikes me as *far* more likely to be able to speak with rodents. You know that Eric Adams knows words that are considered deeply offensive slurs to voles, he’s shaken down ferrets and flattered raccoons.

Powerful argument for sticking with Fahrenheit.
Although Celsius makes summer more bearable.
Maybe we should switch forth and back, when we move the clocks forward or back? (Because there isn't nearly enough complaining about DST already.)
