NASA's Perseverance rover successfully touched down on Mars last week, capping a perfect set of three arrivals at the red planet. Dr. David Brain joins us to tell us about the plans for one of those missions, and how it will help us unravel Mars' complicated climate history. Plus, we have a series of Mars trivia questions and a look at what the future holds for Mars exploration.
Richy Valens was taken from us all too soon on the day the music died. But while the Valens' band died that day, the Valence Band continues to be occupied by electrons hanging out, doing their quantum electronica dance, just below the fermi level in solids throughout the universe. Whether you're an insulator or a semiconductor, pop into the Valence Band for some rest and respite, away from the bumping, bopping, and mayhem in the conduction band. Stay close to your electronic and atomic family by spending time in the Valence Band, where the rhythm is quantum, the beat is electronic, and the moves are out of sight. The Valence Band, the happiest place on Earth (Walt Disney World).
