In 2017 I sat for an interview with Nick Davis, director of the Ted Williams documentary on PBS. Snips were used in the broadcast film, but here is the longform interview: www.pbs.org/wnet/america...

PSA: Examples of a judicial warrant and an administrative warrant. ICE cannot enter your home with only an administrative warrant.

Here's a great story for these troubled times: share.google/s6IPE19JdMNL... I met Donell today. He's one great guy!

This is an incredibly interesting article, with incredibly important implications for how teams think about long-term deals for players.

"An analysis of footage from three camera angles shows that the motorist was driving away from—not toward—a federal officer when he opened fire." Great video analysis of Minneapolis shooting from NYT. These frames show drawing of gun and exact moment of first shot. www.nytimes.com/video/us/100...

It’s a good time for nineteenth-century style political cartoons. This one from the Toronto Star

Last night I wrote to you about Trump’s desperate efforts to rewrite history. Today, on the taxpayer funded WH website, he’s using our resources to pursue Orwellian 1984ish revisions. It’s our job to stop him. open.substack.com/pub/joycevan...

Re: the Phamgraphs article, in which I'm mentioned, and this sentence: "If WAM can measure this for homers, perhaps they can measure it for outfield fly balls, as well." @weatherapplied.com does measure the wind impact of every fly ball. Also, for every pitch. www.nytimes.com/athletic/694...

I bat and throw left-handed but write right-handed. Evidently not so unusual.

9*(54/40)^2=16.4

As a quickee estimate, the movement scales with the square of the flight distance.

Following up on your question: I suspect that others are also analyzing the 2025 data on torpedo bats. And I further suspect that, based on this analysis, the usage of these bats will increase in 2026. We shall see.

Yes, I have done some analysis. It is still in progress and not yet ready to go public. Also have done ( with my collaborators) lab measurements. Those results will be shown at a conference in June. Perhaps prior to that.

Watching the Twilight Zone Marathon on SyFy right now, a fitting way to start the new year.

Looking forward to it. I've been watching the video for the past 3 hours.

Join us in wishing Sandy Koufax a happy 90th birthday! Some Hall of Fame advice from the legendary lefty: “I became a good pitcher when I stopped trying to make them miss the ball and started trying to make them hit it.”

The Guns of August, by Barbara Tuchman, about the buildup to and the first month of WW1. I read it a few years ago and am currently reading again. Much of the 20th century has its origins in WW1

My suggestion: The Third Man

There’s a Yiddish word that fits. Paskudnik — an evil, nasty, revolting man. That’s him. He’s a Paskudnik. And we will celebrate when he’s gone like we’ve never celebrated before.

Hey @robmains.bsky.social . Happy Hanukkah! You should post a link to your Hanukkah verse from a few years ago.

Happy Hanukkah to all those observing.

Given the choice of whom I prefer to listen to, HCR wins and it's not even close.

Einstein and baseball:

Not sure if it's far side but it's my favorite

this excellent review of oral arguments in trump v. slaughter gets to the profound dishonesty of the conservative majority — the refusal to own the consequences of their actions

Home run! David Gagnon took a detour from his path to becoming a professor focusing on fluid dynamics. He now analyzes baseball for the @nationals.com. #whatcanphysicistsdo #mlb #nationals #physics #baseball

New results on the existence, or not, of sterile neutrinos. www.nytimes.com/2025/12/03/s...

youtu.be/J3i3F2e4IYs?... Some really neat physics in this video. It provides a clear explanation for why a football spin axis follows the parabolic trajectory. The answer is not obvious but very well explained in the video. Enjoy!

Out of this World: Zena Cardman www.washingtonpost.com/washington-p... Mazel Tov to Zena, who is the daughter of my former UIUC physics colleague Larry Cardman and wife Helen. Unfortunately Larry passed away a few years ago and did not live to see Zena in space.

How constant is the fine structure constant? New experiments on thorium-229 nuclei (which are 6000x more sensitive than other atomic and molecular systems to changes in this constant) could answer this question, with implications for theories of dark matter. 🧪⚛️ physicsworld.com/a/looking-fo...

My preference would be World War 1

The Civil Rights Movement. EYES ON THE PRIZE is solid, but over forty years old. There's been a lot of great work on the movement since then. And while EYES leaned heavily on interviews with participants, a new series could make use of that scholarship to get beyond the Montgomery-to-Memphis arc.

Or fluorine, as per General Jack Ripper.

OK, thanks for clarifying. To do the separation properly requires 3D spin axis. 2D is good enough in the approximation that velocity is in the y direction. See baseball.physics.illinois.edu/HawkeyeSpinA...: "...while the approximation is useful and appealing, it should be used with caution"

How does that get you the spin efficiency? Also, that doesn't answer the question about how the Magnus movement is determined. It requires some relationship between spin-to-speed ratio and the movement. What relationship was used?

He shared on twitter, and it's not using 3d spin vector but instead using statcast's induced horizontal and vertical movement without gravity projected onto statcast's 2d spin_axis. So [horz,vert] dot spin_axis_unit_vector
