The Scientific Odyssey ·

2017/04/02

This week we look at the work of William Herschel, Giuseppe Piazzi, Heinrich Olbers, Urbain Le Verrier, Alexis Bouvard and Johann Galle as they discovered new worlds in a Newtonian solar system. We consider the mathematical frameworks of Laplace and the Titius-Bode Law as guiding physical laws for the investigation of the natural universe.

Scientific Odyssey Unscripted-The TRAPPIST Discovery

The Scientific Odyssey ·

2017/03/02

IN this impromptu and unscripted episode, I talk about the recent announcement of the discovery of severn earth-like world orbiting a nearby class M star now named TRAPPIST-1 after the telescope used to make the initial discovery. I look at how exoplanets are discovered, the specifics of this discovery, what we know and why it is important. Also discussed are the ideas of scientific collaboration and the concept of universality.
