H. U. Sverdrup

Died 21 Aug 1957 at age 68 (born 15 Nov 1888).Harald Ulrik Sverdrup was a Norwegian meteorologist and oceanographer known for his studies of the physics, chemistry, and biology of the oceans. He explained the equatorial countercurrents and helped develop the method of predicting surf and breakers. As scientific director of Roald Amundsen's polar expedition on Maud (1918-1925), Sverdrup worked extensively on meteorology, magnetics, atmospheric electricity, physical oceanography, and tidal dynamics on the Siberian shelf, and even on the anthropology of Chukchi natives. In 1953, Sverdrup quantified the concept of "critical depth", explaining the onset of the spring phytoplankton bloom in newly stratified water columns.

Paul F. Tompkins: Airline Security Drawings

As Im standing there, I see they have a little sign with pictures of things you are not allowed to bring on the plane anymore. And they have, like, little drawings: circle, line through it, No! One of the things you cant bring on the plane anymore is a bomb -- no, no, they had a picture, cant do it. And it was the classic cartoon bomb, like the bowling ball with the little sparky whip coming out of it. And then you might think, Oh, I got a way around that. Uh-uh, not so fast -- they also had a picture of the bundle of dynamite with the clock.
