Today we celebrate the 4th of July with a tribute to American scientific and technological achievements—and we’ve thrown in some fireworks, just for fun.
Chemistry has been part of the American experience ever since the settlers at Jamestown built a lab for blowing glass and assaying metal (you can learn more on our Jamestown episode). Today we celebrate the 4th of July with a tribute to American scientific and technological achievements—and we’ve thrown in some fireworks, just for fun. We start with Glenn Seaborg and the trans-uranium elements. Named for their position on the period table following uranium, the trans-uranium elements are all radioactive, with short-half lives, and all have their origins in the lab. Seaborg’s research group at the University of California discovered 10 of them. Next, we chat with Dale Keairns, the president of the American Institute of Chemical Engineers, about a century’s worth of engineering progress. Element of the Week: Americium.
