Creating the Vietnam War Memorial

The Vietnam War has a controversial legacy in United States history and culture. The U. S. was immersed in the conflict in Vietnam for 20 years. The draft of young men to fight far from home in the seemingly endless war led to widespread resistance and protest against the war itself. This discontent led to a disrespect of veterans when they returned. Since then the sacrifice of soldiers has been honored in memorials, movies and books. The Vietnam Veterans Memorial was built in 1982 in Washington DC. But it was controversial at the start because it honored soldiers by etching the names of the more than 58,000 soldiers killed in polished black granite. Listen to this radio story to learn the history behind this war memorial.

Da Vinci and Patterns of Tree Branches

Trees can stand up to 100-mile an hour winds during strong hurricanes. Why do some trees survive and others don’t?
