omega tau - English onlyPhysics beyond the Standard Model Guest: Valerie Domcke Host: Markus Voelter Shownoter: Andy Joiner A while ago we had a whole series about LHC, ATLAS and particle physics in general. Despite all we know about what our world is made of and the explanatory power of the standard model, there is also a variety of open questions and currently unexplained phenomena. These include dark matter, dark energy, the neutrino mass, the CP violation, the hierarchy problem, and of course the unification of the standard model with gravitation. In this episode, CERN’s Valerie Domcke explains what it’s a...2021-03-061h 42

omega tau - English onlyModern Fission Reactors Guest: Jacopo Buongiorno Host: Markus Voelter Shownoter: Andy Joiner In this episode we take a look at newer generations of fission reactors, those that are currently being developed or researched. Our guest is Jacopo Buongiorno of MIT. We discuss some of the high-level goals of these new reactors, such as increased safety and efficiency, and then look at a few of the interesting new designs and how they realize these goals. We also briefly cover some of the policy arguments around keeping fission in the mix for combatting climate change. ...2021-01-041h 54

omega tau - English onlyExistential Risk Guests: Toby Ord Host: Markus Voelter Shownoter: Jochen Spalding Humanity has always been exposed to potentially catastrophic risks that might endanger the continued existence of humanity. Asteroid impacts or supervolcano eruptions come to mind. But since about the invention of the atomic bomb, humanity has been able to wipe itself out, adding self-made existential risks to the natural ones. Oxford philosopher Toby Ord argues in his book The Precipice that those risks are much more likely than the natural ones.

omega tau science & engineering podcastPlasma Wakefield Acceleration with AWAKE Guest: Edda Gschwendtner Host: Markus Voelter Shownoter: Fabian Zeisberger A major component of particle accelerators like the LHC are the actual accelerators; the current approach relies on radio frequency cavities. However, their acceleration gradient, measured in Volts per meter, is limited. This means that future accelerators, especially linear ones, will become longer and longer to reach the desired energies. A new approach to particle acceleration relies on plasma wakefields, this technology can deliver orders of magnitude more acceleration per distance.

But how can we tell whether a particular event can be attributed to the changing climate? Would it have happened in “normal” climate as well, and if so, how would the event have been different?
