Ronald L. Rivest: Red Sox Ceremonial First Pitch

On April 16, 2004, I threw out the ceremonial first pitch for the first Red Sox - Yankees game of the 2004 season!

Alex helped me practice pitching just before the game.
Jon Hartman had given Ron pitching pointers earlier in the week, and Gail had helped practice too!
Thanks, Alex, Gail, and Jon!

Let's see... h(t) = h0 + v0 t - 1/2 g t^2 ...

Announcer:
"IT'S NOW TIME FOR OUR FIRST PITCH CEREMONIES. EVERY FRIDAY EVENING THIS SEASON, WE WILL HONOR A MEMBER OF THE MEDICAL AND SCIENTIFIC COMMUNITY AS OUR MEDICAL ALL STAR.

So, g is 32 ft / s^2, but what is t?

Hmmm.. 60.5 ft to home plate... I probably pitch at 20 mph = 29.3 ft / sec...

It was cold! No wonder Pedro blows on his pitching hand!
The moisture definitely makes the ball less slippery...

Initial dh/dt = 32 ft/sec, angle is arctan(32/29) = 47 degrees...
Hmmm... that sounds like a fly ball... I think I better forget the math and throw this thing!

Jon said point the left foot towards home plate...

I hope that cute ball girl is a good catcher!

Strike (close enough!).

The Red Sox folks let me keep the ball (which had been engraved...)

Thanks to Gail, Alex, Chris, Joe, Prabhakar, Becca, Ann, Arvind, Nisha, Jon, Jim, Beck for being there with your support!

That was both an honor, and very exciting!
Go Red Sox!
The Sox won, 6-2!
