Can someone post a link that is not behind a paywall

How weather can impact baseball, from summer heat to cold winters | Illinois Public Media
For some reason, I've been getting a lot of inquiries lately about the effect of weather on baseball. The latest is a podcast interview I did for Illinois Public Media with Professor Steve Nesbitt ...

Here is a stamp
Update with drag data through July 9. Cd has stabilized at a level a bit above the 2019 levels. In July, both Cd and fly ball distances essentially the same as in June. Home runs per batted ball at 0.050 in June-July, up from 0.042 in April-May, partly due to higher temp, partly lower Cd
Or how about doubly magic 56Ni?

I agree that metal bats do not necessarily result in greater fly ball distances. Left unregulated, they increase in distance over wood can be large. Of course, NCAA and other organizations regulate the performance, resulting in a cap on how much they can outperform wood.

The Mantle Griffith Stadium Home Run
I used Sanborn maps extensively to help determine the fate of the famous Mickey Mantle Griffith Stadium home run in 1953. You can read all about it here: baseball.physics.illinois.edu/mantle565.htm

Amazon.com: A Perfect Coincidence: The Extraordinary Friendship and Astonishing Deaths of John Adams and Thomas Jefferson eBook : Rasenberger, Jim: Kindle Store
The relationship between Adams and Jefferson, including their near simultaneous death on the 50th anniversary, is nicely recounted in this recent book: a.co/d/0av1UhGF

Today as we celebrate the 250th anniversary of the Declaration of Independence, we are also commemorating the 200th anniversary of the passing of John Adams and Thomas Jefferson, the "North and South Poles of the American Revolution".
I've been there but not since the Rod Serling statue. In fact, I was married there!
One of the most consequential achievements of my career is developing the BBCOR standard for the NCAA. One can love it or hate it, but it certainly has changed the game. And it's among the best examples of how science can be brought to bear on the game of baseball.
Nor can I vote for him. But I can send him money...and I did!
The link in my post is to an article I wrote in 2020 analyzing the factors that contribute to variation in fly ball distance. The analysis used Trackman data. I would love to update using Hawkeye, but the spin information seems to be less reliable to that of Trackman.
Currently reading Empire of Liberty (738 pages!), Gordon Wood's contribution to the Oxford History of the US series. The book covers 1789-1815. He is my favorite historian of the founding era. This book is well balanced between narration and analysis.
Good question! Actually not. However, the scatter is already quite large (sd~17 ft) since I am only including EV in fit (at fixed LA). In particular, I am neglecting spin, which is a major contribu...

Top plot shows distance-vs-EV for LA=25-30 deg, separated by months, along with linear fit. Middle plot shows just the fit, indicating about ~11 ft greater distance in June than in April. I have separately determined that about 1/3 of that difference is due to higher temp, 2/3 due to smaller Cd.
