It's PI Day, and Spencer Wilken is back on La Crosse Talk PM to discuss the upcoming solar eclipse, how her PhD is going in Astronomy at the University of Illinois and, we’re still doing our regular segment, where we break news that happened from 50-150 years ago.

We saved that for last, but it has to deal with the invention of the jetpack and how the three men involved ended up being, kidnapped, murdered and serving jail — all while the original jetpack was hidden and has still never been found.

Wilken also gives me a basic astronomy quiz that college students take, including knowing the difference between astronomy and astrology. She also gives a kind of amazing fact about astrology, for those who identify with a certain sign — you may not actually be that sign anymore.

But, we began the show just getting an update on studying for an astronomy PhD and how Wilken takes to heart being a woman in science and inspiring girls to also be interested in the field.

After that, we discuss multiple facets of the eclipse, including the weird things animals do — like tortoises getting down.
