omega tau - science & engineering [English only]

[This is the feed of only English episodes.] How do scientists uncover phenomena and explain their connections? How do engineers design machines, methods and infrastructure? At omega tau, experts give detailed answers. Over the last ten years, we have produced 300 episodes in which we dug deeper, until we ran out of questions. Join us on our journey through the world of science and engineering: the closer you look and listen, the more interesting things get.

355 – Supercomputing for COVID-19

In this episode we look at how supercomputers are used to help with managing the pandemic. It's a double-header with two guests. We start with Cineca's Andrew Emerson. As part of the EXSCALATE 4 COV EU-funded research project, he works of virtual sc[...]



350 – Existential Risk

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 [...]

348 – ATLAS Computing

To conclude our detailed look at the ATLAS experiment, this episode looks at the computing infrastructure. We start out with the trigger systems that decide, very quickly, whether the data from a particular collision is worth keeping. We then discus[...]

345 – ATLAS Science

Guests: Philipp Windischhofer   Host: Markus Voelter   Shownoter: Andy Joiner After understanding the history and development of ATLAS (and covering the LHC and particle physics in general) in previous episodes, we are now at th[...]

344 – History and Development of ATLAS

ATLAS is one of the two general-purpose experiments at the LHC. It has been conceived, designed, and built over decades by hundreds of scientists and engineers from dozens of countries and hundreds of organizations. My guest, Peter Jenni, has been t[...]

343 – Flying and Testing the F-35

The Lockheed F-35 Lightning II is going to be more or less what the F-16 and F-18 are today: the backbone of the US and NATO land and sea-based air forces. It is a multi-role fighter, and one of its versions has the capability to take off with a ver[...]

341 – Emergency and Intensive Care, Ventilation

In light of the current situation, we have decided to record a couple of episodes that cover some of the relevant background in terms of biology, medicine and healthcare. In this first episode we discuss emergency care and intensive care with a spec[...]

340 – Plasma Wakefield Acceleration with AWAKE

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 accel[...]

Special – Once You Start Asking

Over the last two years, Markus wrote a book about some of the repeated topic covered on omega tau: SOFIA, Enterprise, Aerospace, Gravitational Waves, Telescopes, Models and Particle Physics. The book, called Once You Start Asking is now available a[...]

150.5 – Controlling the ELT

Six years ago, in episode 150, Jochen Liske of ESO told us about the Extremely Large Telescope that is currently being built in Chile. This episode is a continuation (which is why this is a kind of bonus episode labelled as 150.5) in which Thomas Pf[...]
