omega tau science & engineering podcast

Markus Voelter and Nora Ludewig produced omega tau from 2008 to 2023, creating 400 episodes of deeply technical science and engineering content before ending the show with their final episode. Voelter brought serious technical chops as an interviewer -- he clearly did his homework before every conversation, and guests consistently remarked on the quality of his questions. The format was simple: long-form interviews with scientists, engineers, and researchers about their specific domains of expertise. But the depth was extraordinary. Episodes covered particle physics at CERN, aircraft engine design, bridge construction, satellite operations, nuclear fusion research, Antarctic expeditions, and hundreds of other subjects, often running well over an hour to give the material room to breathe. The podcast was produced in both English and German, with many episodes available in both languages. What made omega tau stand apart from other science podcasts was its refusal to simplify for a general audience. Voelter asked the follow-up questions that a technically literate listener actually wants answered, pushing past surface explanations into the real mechanics of how things work. The back catalog remains available on all major podcast platforms and represents one of the most comprehensive collections of science and engineering interviews ever assembled by an independent podcast. Even though no new episodes are being produced, the existing library has not lost its relevance -- the physics of turbine design and the challenges of deep-sea drilling have not changed. For engineers who want to understand how the world works at a technical level, this archive is a remarkable resource.
