Video by Science Friday
In this video, Science Friday's Flora Lichtman talks with Thomas Baer, executive director of the Stanford Photonics Research Center, about how to calculate the solar intensity created when concentrating the sun's rays using a magnifying glass. They explain how a magnifying glass can be used to start a fire and why it's dangerous to stare directly at the sun.
Leslie is Science Friday’s Web editor. She has a background in oceanography and is passionate about getting non-scientists and young people to realize how cool science can be.
