And while you're at it, follow Ken Arenson too, @kenarneson.bsky.social

If you're interested in baseball and not yet following Weather Applied Metrics, @weatherapplied.com, you should. And take a look on their blog post about the effect of the atmosphere on home runs. blog.weatherapplied.com/impact-of-at...

This is an excellent idea!!!

Posting this for no reason.

Looks like the jury bought into my air drag argument.

I too am proud of Maine, my birth state.

Has anyone investigated the possibility of commotio cordis?

Has anyone yet taken air drag into account?

Your average Subway 6-inch has an effective range of about 15 feet, making it best for CQC or a sidearm (side-sub?). For increased range and stopping power, you're going to want something baguette-based, like a Croque Monsieur.

Some years ago I did an analysis of a vibrating broken bat. Looking back on that analysis today, I thought it might be interesting to share. It demonstrates how one can learn a lot by making simple estimates, something physicists often do. baseball.physics.illinois.edu/CabreraVibra...

The political pundits seem to contend, incorrectly, that DJT is forbidden by the 22nd amendment from serving a 3rd term. Read it carefully..it says "no person shall be elected...more than twice" Now look at Sections 1 and 2 of the 25th amendment and you'll see a mechanism.

12th Amendment: But no person constitutionally ineligible to the office of President shall be eligible to that of Vice-President of the United States.

Please ask #Maine friends to Vote NO on Ballot 1: absentee ballots: boltsmag.org/maine-questi... and #Pennsylvania friends to vote YES to retain judges. It's critical the Dems keep the Supreme Court

Wild Card Round | Wrigley Field | Oct 1 Merrill hit a high 170 ft-apex fly ball into a 16 mph wind blowing in from right-center. Suzuki drifted back, then adjusts to make a routine catch on a ball that was quietly the most wind-impacted play at Wrigley this series. 𝗪𝗶𝗻𝗱 𝗜𝗺𝗽𝗮𝗰𝘁: −𝟲𝟳 𝗳𝗲𝗲𝘁

50 years ago tonight. "If it stays fair ... home run."

For Pence, it was a "triple double". baseball.physics.illinois.edu/PenceTripleD...

That’s called A Hunter Pence

DC J6: 1.500 arrests DC No Kings: zero Tell me again which side is violent?

One day in the 1940s, he insisted on driving from Yerkes to teach the class despite a heavy snowstorm. He ended up teaching a class of only two that day. The two students (Tsung Dao Lee and Chen Ning Yang) won the Nobel Prize in physics in 1957. Yang just passed away. bsky.app/profile/bloo...

Need I say more...

No Kings, Urbana IL...just getting started

Got it! Thanks for clarifying.

Why the "1"?

Can you provide some details on how you do the constant jerk fit.

Did that 8-6-2 double play really happen? Apparently! So here's everything you need to know about a "ground-ball" double play that was missing the "ground" part! www.nytimes.com/athletic/671...

That was quite a game at Fenway 12 years ago tonight.

Make that 1840-1920

Just got the library copy of "Born Equal: Remaking America's Constitution, 1860-1920", by Akhil Amar, my favorite constitutional historian. This will be the 4th of his books that I have read.

We all learn about quantum tunneling in atomic systems in introductory courses in quantum mechanics. The current Nobel Prize was for the observation of such tunneling in much larger systems, as initially predicted by my UIUC colleague Nobel Laureate Tony Leggett. www.nytimes.com/2025/10/07/s...

Very nice article from Rod Cross: pubs.aip.org/aapt/pte/art...

Curveballs have a downward Magnus force, which is reduced with a tailwind, making it more sustainable to the deadly hanging curveball.

“The Twilight Zone” premiered on this date in 1959.

Surely you jest!

As is by custom on this anniversary, I read again John Updike's great essay, with the words "God's do not answer letters."

10,454 to be exact

Today is the 65th anniversary of Ted's last swing (shown below), resulting in his 521st home run.

The thing I find most interesting about the video is how quickly the vibrations are damped, despite being "free" (i.e., no hands).

If you know any kids that are interested in sports-ball aerodynamics or want to learn more yourself, take a look at this excellent article: www.snexplores.org/article/pitc... Thanks to @pobguy.bsky.social for introducing Wendy and I.

And guess what...it's my birthday too!!

Happy Birthday to the US Constitution!

Here is a clip from that episode, "Nothing in the Dark": youtu.be/9tfyv4BZRug

As we remember the life of Robert Redford, here is his appearance on The Twilight Zone (S3,E16, January 1962), featuring truly excellent performances by both Redford and (especially) Gladys Cooper.

As we approach the 50th anniversary of the "thrilla in Manila", Vann Newkirk has written a superb article about Ali and Frazier, their relationship, and the fight. It is as good a piece of sports writing as I've seen in recent years. I highly recommend. www.theatlantic.com/magazine/arc...

He was an excellent governor who knew how to work across the aisle, mainly with Mike Madigan, to get things done.

Yes

Radians/sec

Almost. Since v= sqrt( vx^2+vy^2+vz^2), that must also be modified. Using v-vwind is not correct.

Since I can't watch Red Sox v NYY on MLB.TV, I'm listening to the audio. Great to hear Joe Castiglione again.

Today I am thinking of my classmate and friend Bill Caswell, one of the many victims of 9/11
