Daily Bread for 11.8.11

Good morning,

Rain falls on the Whippet City today with a high temperature of forty-three.

The Wisconsin Historical Society recalls a day of political foolishness in Milwaukee:

1910 – First Socialist Mayor Elected in Milwaukee

For all the talk about who’s a supposed socialist, there was a time (and for Vermont still is a time) when actual socialists were the socialists of whom people spoke.

How foolish to think that skateboarders are just skateboarders, as Skateboarders rock physics: Experienced riders show gut knowledge of slope speeds.  Bruce Bower reports that

A ball travels faster down a relatively long incline that angles steeply downward in two sections separated by a flat stretch compared with a shorter incline that angles downward modestly but without changing slope. People generally don’t realize this, but experienced skateboarders often do, said psychologist Michael McBeath of Arizona State University in Tempe. Skateboarders call on motor memory to determine intuitively that a sharp early descent creates a speed advantage, he reported November 5 at the annual meeting of the Psychonomic Society.

“This is a hard problem, even for physics professors that we quizzed, but skateboarding experience improves estimates of slope speeds,” McBeath said.

There’s a different problem even slower-moving, non-skaeboarders can try. Google’s puzzle of the day is about a creature of the sea: “A fish that is 1,200 times more poisonous than cyanide can be made into a delicacy requiring many steps of preparation before it’s safe to eat. What is the name of the poison in this fish?”
