How were the ancient Egyptian day and night divided? What do we know about keeping time during the span of pharaonic history? Have many objects used for timekeeping survived? Do we know who made and used them and why? This talk discusses ‘formal’ methods for measurement of hours in ancient Egypt, giving an overview of the surviving evidence including sundials and water clocks. We will compare different instruments and trace the extent to which we understand the time-keeping function of each.

What is the sound of a twinkling star? Can planets keep a beat? How loud was the big bang?

Showtime: 3:00pm Often, when we think of the Solar System, we think of the planets and the Sun and nothing more. But what about all the other stuff? There are millions of asteroids in the asteroid belt, tens of millions of objects in the Kuiper belt, and probably trillions of objects in the Oort cloud—not to mention the hundreds of moons and dozens of dwarf planets that are members of the Sun’s extended family.

Showtimes: 7:00pm, 8:10pm, 9:15pm The stars in the night sky seem unchanging and eternal, and have remained the same for the history of human civilization. However, over millions and billions of years, new stars are born, live out their long lives, and eventually die in a blaze of glory. In this show, we will be exploring the lives of stars by visiting stellar nurseries, supernova remnants and much more!
