This post is a Driving with Jordi, and a Dr. Jeff’s Jeffism.


“Daddy, how long would it take to drive around the Sun?”


So there we were on the Washington, DC, beltway heading for his elementary school. We were cruising at 60 mph—yes, on the beltway, I know!! (© Craig Ferguson, CBS).  Jordi said, “daddy, how far has this car gone since you and mommy got it?” I looked down at the odometer and read 249,000 and some odd miles. Cool! The ’95 Camry was doing just fine. Besides getting close to the 250,000-mile mark, the space guy in me knew that the Earth’s circumference is about 24,900 miles. “Jordi! This car could just have gone around the entire planet Earth 10 times!” He wasn’t expecting that answer. He thought that was … way cool. Cars aren’t supposed to be able to go around an entire planet are they?
