Lunch was great! Thanks for meeting with me. I am sure I did most of the learning, and my speculation on the cause of the Skin effect was not even wrong. I hope you'll have a chance sometime to look at that book about energy and let us know what you think. It happens that I was at Air & Space on Saturday too! I took the kid to see "Journey to Space" in the IMAX theater. The arresting imagery was thrilling and made it a little harder to maintain my skepticism regarding NASA, but I still took another jab at am_Unition.
I'm glad you tagged me, I didn't get an alert. Now I've got something to think about on the long drive tomorrow. Also, it warms my little heart to hear that you guys tagged up and found yourselves discussing concepts like "skin depth" :).
I certainly had a lot to think about! After we talked I looked up Oprah's marathon time. I'd toyed with the idea of running a marathon but had thought I needed to get below 4:00. Turns out the average time is more like 4:20-4:40. That seems much more achievable for me, and I may give a half marathon a try in the spring with the goal of doing a full marathon later next year or early in 2017.
