Behold beryllium, an exceptionally light, strong metal that is both prized and poisonous. Found in minerals such as emeralds and other forms of beryl, beryllium is highly conductive to heat and electricity, nonmagnetic, capable of great elasticity, and impervious to a wide range of temperatures, making it a favored material for aerospace projects such as space shuttles and satellites. In this video you will discover the element’s ancient and atomic histories with host Ron Hipschman!

Join Dr. Jay Daniel, Director of Engineering at L-3 Integrated Optical Systems Tinsley, to explore beryllium’s central role in the future James Webb Space Telescope.
