The problem with reality at the atomic level is matter behaves like a particle and a wave. Matter travels as a wave but we tend to experience it as particles. Quantum mechanics handle this really, really well. But our minds have trouble grasping this wave-particle duality. Dominic describes some of the specific quantum behaviors we still struggle to grasp.

Ever since quantum mechanics was created the great minds have been trying to understand it. It predicts all these weird behaviors (that really happen) but it makes no sense to anyone why they happen. So here's Dominic to explain all the various interpretations and why none of them are very satisfying. Or you can jump to the end of the video and have a biscuit as he suggests.

The Ligo and Virgo gravitational wave detectors created a sensation by detecting the merger of black holes and are now detecting another merger every five days. The LISA mission scheduled for launch in 2034 will take gravitation wave detection to new heights. Based in space a three satellite constellation will detect the mergers before they occur so the region the black holes reside in and the merger can be observed with traditional light telescopes.

Let's hope you're comfortable with redshifts and galaxies that are 13 billion light years away because it's time to bend your mind a bit, a great bit, more. In the 13 billion years since the light we see left that galaxy a lot has happened in the universe; 13 billion years of history to be precise. Dominic tells you what happened in that time and the implications for today.

Virus infect virtually every type of cell from single cell bacteria to the various cells of the various organs in complex life forms so there are a huge number of them. Presented here is general information about virus types and classification, how they enter, replicate and escape from cells to spread, cell immune responses and vaccines.

Doomsday scenarios are a popular topic for science fiction and, from time to time, news stories. But with so many ways humanity could be wiped out which do we really need to worry about. Dominic prepared a chart plotting the likelihood of the various calamities versus the number of casualties to provide some idea of where to focus mitigation efforts.

Sixty-one fundamental particles, various categories of particles, three fundamental forces (gravity not included), a bunch conservation laws and symmetry violations all make up the standard model of fundamental particles. And Dominic will explain them all. But he, like all physicists, has some questions too.

Here is a comprehensive introduction, or review, of black holes. Dominic presents his map of black holes starting with how they form then proceeds to the various types and their properties. He concludes with what is unknown and speculated about black holes which is a large part of the map because they are still mysterious.
