231 – The Future Circular Collider

Rate Episode

Particle accelerators are the backbone of today’s particle physics research and help us understand the smallest building blocks our world is made of. To understand this deeper, more powerful accelerators are needed, beyond what is possible with today’s LHC. The world’s physics community is continuously running studies to explore science questions and evaluate the required accelerators; one of those the studies is the Future Circular Collider study led by CERN. In this episode we discuss the science questions as well as the core engineering challenges with the two leaders of the FCC study, Michael Benedikt and Frank Zimmermann.

The sea ice in the arctic and antarctic regions of the earth is an especially sensitive indicator of the earth’s climate, and in particular, the current overall atmospheric temperature of the planet. It was recently reported to have reached a new low. Our guest, NASA’s Walt Meier explains why this is the case and which processes govern the increase or decrease of the ice. We then discuss how the ice mass is measured based on satellite and how its thickness is estimated based mostly on in-situ measurements. We cover climate modeling and its connection to sea ice and conclude with an outlook on future research.

Tidal power refers to extracting electrical energies out of the tide streams in oceans. Various techniques exist. Tocardo is a provider of axial turbines, and our guest, Pieter de Haas, is their CTO. In this episode we talk about tidal power in general, siting, the design and engineering of Tocardo’s turbines as well as the overall economic and technical trade-offs in making the turbines work over the long run.

224 – Flying the F-15 Eagle

When I was young, in the 80s, I was extremely interested in military airplanes, I more or less grew up with three iconic fighters: the F-15, F-16 and F-18. I want to thoroughly cover those airplanes on omega tau, and this episode on the F-15 is a great start. I talk with Jeff Fellmeth, a former F-15A/C/E pilot about the airplane, avionics, trainings, missions and the units he has been a part of. We also talk a little bit about related topics, such as the Bronco and gliders.

The V-22 Osprey is the first operational tilt rotor aircraft. After not always problem-free development and test period, it is now used successfully with the USAF and the USMC. In this episode we talk to a V-22 pilot, Maj. Seth Cannon of the 7th SOS in RAF Mildenhall about the aircraft, some of its systems, and, primarily, about how it is flown. I met Seth Cannon in Bayreuth, where one of the 7th SOS had to land because of problems with a gearbox. Read the story here. This is also where I took the pictures below.
