AstronomyCast 268: Energy, by Fraser Cain & Dr. Pamela Gay

AstronomyCast 267: Infinities, by Fraser Cain & Dr. Pamela Gay

It's time to look deep into history to the birthplace of modern mathematics - Ancient Greece. And the most famous mathematician of the time was Archimedes. We use many of his mathematical theories and inventions to this day; others are steeped in legend and mystery.

We can thank Arthur Eddington for much of our current understanding of stars. He provided some of the breakthrough concepts that explain what's going on, deep inside the hottest places in the Universe. Sadly, the spacecraft associated with his name wasn't so successful.

This week we talk about: Black Holes as particle detectors, New advances in Chinese space exploration, Asteroid research, History of women in space. We're joined by Amy Shira Teitel, Alan Boyle, Ian O'Neill, and Michael Wall. Hosted by Fraser Cain
