The fluid dynamics of baseball pitches

Baseballs break because of spin, or the Magnus force. They also break because of differences between the air flow around them on two sides due to seams, which we call Seam -Shifted Wake. If you would like to learn more about it, check out baseballaero.com/2020/12/23/c...

My dean nominated my wife for USU Veteran of the Year, and I'm attending the lunch in honor of her and others today. She usually hates this stuff, but for once, it's an award she didn't apply for and she's really proud. I'm proud of her. Happy Veteran's Day.

Had occasion go be in the REALLY tiny town of Newton, UT today and spied the nicest little ball field I've seen around here, right at Center and Main, as it should be.

I was very fortunate back in 2018 that a mutual friend introduced me to Ron Jeffries, who gave me a tour of Jolly Pumpkin in Dexter, MI. Very sadly, Ron passed away last year. We lost a true original. Raise a glass to Ron and to Michigan beer, best in the USA IMHO.

This was 6 years ago, thinking about spinning the ball around a seam. not the right part of the seam, as it turned out, but still.

This is my fav from these guys so far. I commented that I was happy they brought it back. They explained that they had to make old beers because new labels have to be approved by the feds, who are closed.

@chloedenmark.bsky.social Hi, Chloe. I'm looking for folks interested in applying Seam-Shifted Wakes to softball. Do you know of any?

Sad and unbelievable.
Math teachers at Cienega High School in Arizona are facing death threats and calls that they be fired after a Turning Point USA employee falsely accused them of wearing Halloween costumes mocking the assassination of Charlie Kirk.
Arizona teachers' costumes weren't about Charlie Kirk. They're facing death threats anyway

This got me thinking that it's too bad that high school pitchers don't have a switch like this so they can ignore bad coaching advice while remaining "coachable."

I'm not sure what to think, but after sending me over the top in less than an inning yesterday, I'm **kind of** enjoying Smoltz tonight? I think he's having a lot of fun.

Calling it. Bringing in a guy with 10 starts on short rest in relief is sketchy as hell.
