NASCAR and Energy Efficiency

It never fails. When I give a talk about The Science of Speed at a University science department (as opposed to a talk for the public), someone will ask “How can you advocate for NASCAR? They’re the biggest waste of gasoline.”

Or something similar.

I’m going to look at this in two ways. People often confuse how much energy is used with how efficiently energy is used. One way to cut back on energy usage is to use less energy, but it’s also possible to use less energy by using the energy more efficiently. […]

Turning at Bristol: A Weighty Matter

A lot of drivers cite Bristol as one of their favorite tracks. It’s a great exhibit for the argument that racing is more than just pure speed. High banks (which we know mean speed!) and a short track, which means tight racing. But a lot of drivers will tell you that Bristol is one of the most exhausting, physically demanding tracks on the circuit. Add to that the inherent stress of short-track racing, where 43 cars are operating in a limited (half-mile) track. […]

The Digital Dashboard

Those of you of a certain age may remember these odd looking flat black vinyl things called ‘records’. Records are analog devices. A groove is cut into the vinyl. A stylus rides along the groove and translates the wiggles in the groove into an electrical signal, which is then transmitted to a speaker, which turns it into a vibration (which, when pleasant, we call “music”.)
