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 […]

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 […]
