John McCarthy, the American mathematician known universally as the father of Artificial Intelligence, died last Monday at his home in Palo Alto. He was 84.
WEEKEND EDITION's Math Guy, Keith Devlin, knew McCarthy and has this remembrance.
KEITH DEVLIN, BYLINE: I first got to know John McCarthy when I arrived at Stanford as a visiting professor in 1987. He was 60 years old at that time, with a towering and, to me, somewhat daunting, reputation.
SCOTT SIMON, host: Jim Bouton knows what it's like to stand on the pitching mound in a World Series with the world watching. He pitched three World Series games for the New York Yankees in 1963 and '64. Of course, he's also wrote the classic baseball memoir about baseball and life, "Ball Four." Jim joins us from Western Massachusetts. Thanks so much for being with us.
JIM BOUTON: Good morning, Scott.
SIMON: Couple of months ago, would a sane observer see the Cardinals winning the World Series?
The Port of Entry at Nogales, Ariz., is in the midst of a massive upgrade to ease congestion caused by up to 1,500 Mexican trucks crossing each day. Nearly two-thirds of the produce consumed in the U.S. and Canada during the winter come through here.
These Mexican trucks stop at warehouses near the border to transfer their loads to U.S. trucks. That's the way it's long been done. Gary Hufbauer, a senior fellow at the Peterson Institute for International Economics, says that adds cost.
It's a huckster's dream: "Try the new Burmese Python Diet. No calorie counting or special foods. Eat whatever comes along, up to a quarter of your body weight. Not only is it good for your waistline; it's good for your heart."
Trouble is, what works in pythons probably won't work for humans.
Pythons employ what scientists call a "sit and wait foraging tactic." In other words, they lie around in a Burmese jungle and wait for the food to come to them. And of course, this can mean months between meals.
Attend just about any of the Occupy Wall Street-inspired protests across the country and you're likely to see a group of people dressed in matching union T-shirts somewhere in the crowd. Typically, they're older than your average Occupy protester but no less enthusiastic in their chanting.
"I've been doing this [protesting] for five decades," said Mike Wisniewski at a recent Occupy Philadelphia protest at The Wharton School at the University of Pennsylvania. Wisniewski says he's a university library employee and has been a union member since 1972.
'I'm Not Regan': Linda Blair played the young Regan MacNeil in the 1973 film adaptation of William Peter Blatty's The Exorcist. In the book, Regan becomes possessed by a malevolent demon who makes her head turn 360 degrees.
A worker stands next to an array of Sharp solar cell modules at a power plant south of Tokyo in August. Sharp was one of 1,400 solar panel manufacturers in attendance at the Solar Power International conference, where industry optimism was high.
Solar power's image has taken a hit lately with the bankruptcy of Solyndra. The California solar panel manufacturer received more than half a billion dollars in Energy Department loan guarantees before going belly up.
But the industry is still optimistic — that much was apparent at the Solar Power International conference held in Dallas in mid-October. Walking into the big hall of the Dallas Convention Center, it was impossible not to be impressed by the huge array of black solar panels hanging from the ceiling.

This undated photo provided by the National Nuclear Security Administration shows the last B53 nuclear bomb. It was dismantled this past week, just outside Amarillo, Texas. It's a milestone in efforts to reduce the number of nuclear weapons.
This past week, the U.S. dismantled the last of its largest nuclear bombs, the B53.
This was a Dr. Strangelove bomb, conjuring up images of armageddon and apocalypse. At the same time, one of the smallest warheads was also removed from the nuclear arsenal.
These are steps the U.S. is taking apart from its arms control agreements with Russia. And thousands more American nuclear weapons are slated for destruction in a process that could take a decade or more.
