Birthday of Albert Michelson the first American to win a Nobel prize for Physics (1907), awarded for his experiment that determined the speed of light, made on an interferometer which he developed and is still used today for measuring the wavelengths of spectrums.
Also, part of the most famous "failed experiment" - The Michelson-Morley experiment. It had a null result. No damn aether. Of course, the Lorentz contraction and transformation came next. Eventually -

And he hated us.Plus he was a proponent of the fullback.
Yes, a hugely influential scientist. The Michelson-Morley experiment (performed in Cleveland, just saying) proved that the speed of light is constant relative to every possible frame of reference. (If Nolan Ryan can throw a baseball at 100 mph, then if he is standing in a train traveling in a straight line at 100 mph and throws the ball in the direction the train is traveling, the ball will be going 200 mph as measured by someone standing immediately outside the train at the instant Ryan throws the ball. If Ryan throws the ball towards the caboose, the ball will be traveling at 0 mph relative to the observer outside the train. Of course, the ball will be traveling at 100 mph relative to Ryan himself. The speed of light is constant relative to every possible observer )December 19, 1852:

I was once really acquainted with the whole relativity thing. The brain is old and feeble now, so I do just make $H!+ up. Just ask my wife and daughter. My wife really busted me on something the other day. We were both howling at a mistake I made about a CD that we bought when we were first married. I'm laughing about it now. I am the official idiot in the family.Stop making stuff up.

Plus, he was a huge fan of the Weather Thread. Chicks at The Skeller loved him!Plus he was a proponent of the fullback.
Thus leading to one of the great mysteries of science: why is Nolan Ryan throwing fastballs on a train?Yes, a hugely influential scientist.

Kramer’s got the caboose!Yes, a hugely influential scientist.

Attaboy.Seriously. As a modern-day player, everyone knows that he would throw fastballs on a plane.
The Richard Feynman lectures on You Tube are fantastic. When Feynman reviews this even an old 2.8 GPA like me can understand this.Yes, a hugely influential scientist.

In my defense my GPA would have been better, but my electives killed me. I could not get my chicken to play the piano and dance in Behavior Mod.The Richard Feynman lectures on You Tube are fantastic. When Feynman reviews this even an old 2.8 GPA like me can understand this.

BTW, when are they going to do a movie about Feynman? Oppenheimer was a dopey lefty with a lack of common sense. Feynman was a true genius, a man of uncanny humor and perception, and he had a backstory that was incredible. From the Manhattan Project, to a Nobel Prize, to the Challenger investigation. He traveled through the 20th Century living a full life and was an inspiration to generations of young people.

Cool. I will have to watch this.![]()

You’re probably familiar with James Gleick’s biography of Feynman, Genius? If not, do yourself a favor and order it. Just a great book. The description of Feynman’s relationship with Freeman Dyson is worth the price of the book.Cool. I will have to watch this.
Thank you. I wasn’t quite up to speed on that. I knew I was waving my arms a little bit in my post but close enough.Happy birthday Al.
Caveat: Al's measurement was that of the two way speed of light, (ie) a send and return measurement . The one way speed can never be measured because there is no way to define the one way speed of light, The two way speed is based on Einstein's synchronization convention that states the speed is the same in opposite directions and that it is neither a supposition nor an hypothesis about the physical nature of light, but a stipulation one makes of ones free will to arrive at a definition of simultaneity
I know that Feynman is often criticized today with challenges to his work. He was not perfect, but he was admirable in so many ways. That New York accent and sense of humor in his lectures makes them a must watch. There is a five hour long series on YouTube where he lectures on fundamental physics and the development of the basic laws that govern physics. Anyone with an adolescent child showing an interest in the subject should have them watch Feynman. He made the world more interesting.You’re probably familiar with James Gleick’s biography of Feynman, Genius? If not, do yourself a favor and order it. Just a great book.

It is my fanboy opinion that Feynman was the greatest mathematician among those who chose physics over mathematics. (Heisenberg was another, Lord Kelvin too.) Feynman won the Putnam competition, a nationwide mathematics competition for undergraduate students in which the annual median score is usually zero.
Yeah, but southern light is still faster than northern light.Yes, a hugely influential scientist.

So I watched the movie. Not what I expected.Cool. I will have to watch this.
I should have written my comments on the movie after this post of yours. I put this here hoping you will see it. Thanks for the tip.Feynman was the greatest Physics 101 teacher ever.
This is my favorite Feynman story, not in Genius: This Cal Tech graduate student goes to the lab early one morning and starts work, thinking that he’s alone in the building. He then hears Feynman’s unmistakable New York accent lecturing from a classroom down the hall. It’s 7 am, too early for classes, wtf? He goes to the classroom and finds the world’s greatest living physicist lecturing to an empty classroom, rehearsing his lecture for later that day. Respect.
