Video Library

Since 2002 Perimeter Institute has been recording seminars, conference talks, and public outreach events using video cameras installed in our lecture theatres.  Perimeter now has 7 formal presentation spaces for its many scientific conferences, seminars, workshops and educational outreach activities, all with advanced audio-visual technical capabilities.  Recordings of events in these areas are all available On-Demand from this Video Library and on Perimeter Institute Recorded Seminar Archive (PIRSA)PIRSA is a permanent, free, searchable, and citable archive of recorded seminars from relevant bodies in physics. This resource has been partially modelled after Cornell University's arXiv.org.

Speaker(s): 

The anatomy of a black hole.

Learning Outcomes:

• What are the mass requirements for a star to become a black hole?

• The anatomy of a Schwarzschild black hole, including the singularity and the event horizon.

• What a traveller would experience if he orbited a black hole, or had the bad luck to fall through the event horizon.

Speaker(s): 

The physical attributes of a black hole and what types of physical evidence astronomers use the locate them.
Learning Outcomes:

• What are the physical requirements for a star to become a black hole, and what properties of that star remain after the black hole is formed?
• The types of black holes, including: the Schwarzschild black hole, the Reissner-Nordström black hole, the Kerr black hole, and the Kerr-Newman black hole.
• What a traveller would experience if he orbited one of these more general black holes, or fell through to the singularity.

Speaker(s): 

An introduction to a few of the major scientists who applied Einstein's ideas to better understand the life cycle of various stars.

Learning Outcomes:

• How Subrahmanyan Chandrasekhar resolved the paradox of the white dwarf star, and how Walter Baade and Fritz Zwicky described the dynamics of neutron stars.

• Yakov Zel'dovich develops the nuclear chain reaction that is the engine that keeps stars burning.

Speaker(s): 

The mathematical predictions made by scientists tell a story of the life and death of stars.

Learning Outcomes:

• How the Hertzsprung-Russel diagram describes the life cycle of stars.

• Depending on its mass, how a star ends its life as a white dwarf star, a neutron star, or a black hole, and where super novas fit in.

• How the mathematical predictions of white dwarf stars, super novas, and neutron stars are slowly verified by the advancement of the astronomical equipment used by astronomers.

Speaker(s): 

We shift our ideas from Newton’s law of gravity to a new set of equations that describe how gravity is a consequence of the curvature of spacetime.
Learning Outcomes:
• John Michell and his hypothetical object called a dark star.
• How to determine the mass of a planet required for the escape velocity of an object to be the speed of light.

• Einstein’s Equivalence Principle.

Collection/Series: 

 

Tuesday Aug 01, 2006
Speaker(s): 

Spacetime tells matter how to move, and matter tells spacetime how to curve.

Learning Outcomes:

• Why gravity can be seen as a curvature of spacetime.

• That Einstein’s field equations describe how matter curves spacetime.

• How Sir Arthur Eddington verified Einstein’s theory of general relativity by measuring the change in position of stars during a solar eclipse.
