Where Are the Time Travelers?

Posted: November 21, 2019 at 9:16 pm, Last Updated: April 23, 2021 at 5:17 pm

Einstein’s theory of relativity suggests that time travel might be possible. We consider why this is true, and how one might build a time machine. We also consider the paradoxes involved with time travel and how they might be resolved.

Tachyons: Messengers from the Future?

Posted: November 21, 2019 at 9:11 pm, Last Updated: March 29, 2021 at 6:31 pm

Einstein claimed that faster-than-light (FTL) speeds are impossible, but some physicists are no longer so sure about that notion. Hypothetical subatomic particles that travel at FTL speed are known as tachyons. In this talk we consider how tachyons might be used to send messages back to the past, and how the existence of tachyons can […]

Artificial Intelligence (AI) Nightmare Scenarios: Summoning the Demons?

Posted: October 31, 2019 at 6:18 pm, Last Updated: June 22, 2021 at 5:24 pm

Some may think of Artificial Intelligence (AI) in terms of Boston Dynamics’ Robot dog, Spot or of software that can defeat the very best human player in Go or Jeopardy. This course is about a much more sinister and serious aspect of AI, the various “nightmare scenarios” that are appearing regularly in the technical literature […]

Climate Change: Preparing for the New Normal in Virginia

Posted: April 26, 2018 at 4:20 pm, Last Updated: June 21, 2022 at 7:02 pm

“Everybody talks about the weather, but nobody does anything about it.” This old saying neglects the fact that all of us are inadvertently doing something about the weather – we are changing it. The reality of global climate change is now undeniable and the likelihood is high that human activities have caused the majority of […]

What is a Planet? Mars, Pluto and Exoplanets as Examples

Posted: March 27, 2017 at 1:11 pm, Last Updated: March 29, 2021 at 6:38 pm

A major topic on the internet today is the question of the definition of a planet. In 2006 the International Astronomical Union (IAU) officially changed the definition of a planet. No longer was Pluto to be called a planet, but a dwarf planet. We will examine examples of objects inside and outside our solar system; […]

Crazy Ideas in Science

Posted: September 10, 2014 at 12:12 pm, Last Updated: March 29, 2021 at 6:32 pm

In this talk I consider how crazy ideas can sometimes lead to great scientific advances, and even cause us to re-examine the nature of science itself. This light-hearted talk will also serve as a template for some creative and humorous uses of PowerPoint that can add interest to your own presentations.

Could Einstein Have Been Wrong?

Posted: September 10, 2014 at 12:11 pm, Last Updated: March 29, 2021 at 6:32 pm

Einstein in his theory of relativity claimed that faster-than-light speeds are impossible. But some physicists are no longer so sure about that notion. This talk will take a look about what faster-than-light speeds imply, and the evidence as to whether faster-than-light particles might actually exist.

Computational Sciences: The Third Pillar of Empirical Science

Posted: September 10, 2014 at 12:08 pm, Last Updated: March 29, 2021 at 7:00 pm

For hundreds of years, empirical sciences as we know them today were based on either direct measurement of objects (or scaled models) or on simple analytic solutions of partial differential equations. The advent of supercomputers in the 1980s added a third option: computational sciences. The talk explores the origin, outlook and consequences of this third […]
