This is CBS. I am the world. I'm John Bachelor. Play Tectonics. It is accepted for geology not only on planet Earth, but looking to the heavens, to our solar system

and beyond the exoplanets, that planets move.

The surfaces of planets, the cores of planets move. Once upon a time that was

controversial. I was a very young man. It was the fall of 1966 at Princeton

University in the Department of Geology. Of course was Geology 101 which in the

locker room for freshman football I was told to call rocks for jocks. I was

there not sure what what was happening around me but there was a wonderful museum part of the geology building at Princeton

which resembled I think a Victorian museum and had samples everywhere.

Now I learned many decades later that I was at the crossroads of geology coming to understand how our planet is shaped, how our North America,

our South America, Asia, and that we're continuing to move.

So that 250 million years ago we looked like this, 250 million years from now will look like that.

And to help me understand what I didn't understand in 1966, I welcome Larry Cathels. He is my guide here, writing most recently an obituary

for a professor of Princeton University, Professor Jason Morgan, who's left us.

Larry is the man to do it of course because he's Princeton 65 and understands the campus life very well why

Roxford Jocks would show up in a revolutionary period.

Larry was a professor, is Professor Emeritus

at the Department of Earth and Atmospheric Sciences

Cornell University, Ithaca, New York.

Professor, a very good evening to you.

The continental drift that I came to not understand in 1966.

It didn't much exist except for as a controversy.

Play Tectonics more formally known.
