This episode is a conversation with W. David Woods about his wonderful book How Apollo Flew to the Moon where he describes in great length all the detail a geek wants to know about how the Apollo spacecraft and the flights to the Moon worked. In the episode, we basically go through an Apollo mission and discuss aspects such as the mission structure, the workshare between the crew and mission control, communication and telemetry, guidance and navigation, approach, landing and re-launch on the Moon as well as re-entry and landing on earth.

This episode is a conversation with Michael Commer of the Berkeley Lab about geophyiscal modeling in oil exploration. We start with a brief discussion about how oil gets created and in which geological formations it can be found. We then proceed to talk about various means of finding oil using various means and techniques. The majority of the episode’s conversation revolves around how numerical mathematics can help interpret, refine and work with exploration results.

This episode is a conversation with Dieter Schimanski, the Manager Test & Operations of the European Transonic Windtunnel. In late June of 2011 I had the chance to visit the facility. The episode starts out with a one hour conversation about aerodynamics and the concepts behind the ETW. The rest of the episode is essentially an audio report of the tour I took of the facility. To better grasp the magnitude of the facility, I recommend you take a look at the picture gallery.

In this episode I talk with NASA Dryden Test Pilot Dick Ewers about his work now and in the past. We start by revisiting his test pilot training at the US Navy Test Pilot School, and proceed to talking about his involvement in early F-18 flight testing. We then compare this work to the F-18 work he does today, using the aeroelastic wing and autonomous air refuelling projects as examples. We conclude our conversation by discussing his pole overflights with the DC-8, as well as his hurricane penetration flights with that same aircraft.

In this episode we talk with Brano Kemen about his Outerra project, a 3D planetary engine for seamless planet rendering from space down to the surface.. We discuss the history of the project, its most interesting features, some of the physics, as well as some details about the rendering in the system. I highly recommend taking a look at the Outerra Youtube Channel, specifically the Himalaya Trip and the Apache flight.

This episode covers Bitcoin, a digital, decentralized currency. In our conversation with Gavin Andresen, the technical lead of the project, we cover basic economics of money, the way users interact with Bitcoin, as well as the technical implementation of the system. Bitcoin uses a couple of clever ideas about implementing distributed clocks and global ordering, and is a very nice example of applied cryptography.
