Earth Rotation from Galileo Imagery: 3600 x Real-Time
This animation is one in a series created to show an accurate representation of the Earths rotation at different temporal resolutions. The animation is created from images taken by the Galileo spacecraft during a close pass of the Earth on December 11-12, 1990. The animations range from real-time, in which no rotation can be perceived, to 3600 times real-time, in which both the Earths rotation and cloud motion can bee seen. The series also includes an animation in which the Earths rotation has b

Jim Vacarella Describes Avoiding the Draft During the Vietnam War
For young men like Jim Vacarella, the draft stood as the prime symbol of the war in Vietnam. Millions of young men tried to evade the draft: some fled to Canada; many feigned physical or mental illness, others used family connections to gain safe positions in the National Guard. For some, resisting the draft became an important way of protesting the war, and a few thousand men took public stands as draft resistors, burning their draft cards and challenging the government to imprison them.

Urethral Catheters: A Historical Review
In the Graeco-Roman era and in the Middle Ages in Europe, S-shaped bronze catheters with one terminal eye were in common use. In the East, the evolution of urethral catheters started with the firm establishment of Muslim supremacy, and by 1013, straight or one-curve catheters made of gold, silver, copper, lead or salve of white lead with a rounded end and many side holes and a stylet were the standard instruments. Then in Europe in 1853 a prototype of the Foley catheter was designed. The next im

Automotive Drum Brakes
Do you know when the first car was built? Do you know who built the first automobile? Would you guess, Henry Ford? Try again. Do you know by what means they used to stop that car? We know the brakes on the vehicles we drive today are quite different from those back in the 1800s. While knowing the history of the automobile is interesting, knowing how they work is also interesting. The automotive brake or to be more specific, the drum brake is what this instruction is designed to review. In this i
