Bret Ernst: Blame America

Everybody likes to blame America for everything. What are we, only 233 years old? These other countries are thousands of years old. Not only did they not get it right, but a lot of times they screw up and ask us for help. Thats like a 90-year-old man asking a two-year-old for advice.

Fred Whipple

Died 30 Aug 2004 at age 97 (born 5 Nov 1906).Fred Lawrence Whipple was an American astronomer who proposed the “dirty snowball” model for comet nuclei. In the 1930s, using a new, two-station method of photography, he determined meteor trajectories and found that nearly all visible meteors are made up of fragile material from comets, and that none come from beyond the solar system. Whipple suggested (1950) that comets have icy cores inside thin insulating layers of dirt, and that jets of material ejected as a result of solar heating were the cause of orbital changes. This model was confirmed in 1986 when spacecraft flew past comet Halley. Whipple's work on tracking artificial satellites led to improved knowledge of the shape of the earth and greatly improved positions on earth.
