Remember the days when you were able to perform partial integrals with ease in math class? Or the time you could quote Adam Smith‘s labor theories from heart? It’s amazing how quickly our minds erase knowledge that don’t pertain directly to our careers or interests. Wouldn’t it be nice to be capable of retaining more than just a snippet of our past accomplishments?

I received an email from my former mentor at NASA (They forbid use of their “meatball” logo on unauthorized websites) the other day. He wanted me to stress test some revisions on software I wrote years ago with him. I struggled even to generate a data set for testing…what do I use for the supersonic area ratio? What is the mass ratio? What are expected values for normal chamber pressure, and do I want to calculate it in frozen state or equilibrium? Damn. This stuff really is rocket science. How the hell was I able to do this in college, when I didn’t even know what the periodic table looked like in high school?

I started reminiscing about what had happened in those days. I remember that NASA had many enrichment programs for students. I had been accepted into a college scholars program with the notion of redesigning some internal branch websites and writing TPS reports (read: Office Space). One of the engineers was kind enough to discuss his research with me, and vocalized one of his side projects with me. I volunteered to help out, and somehow managed to write most of the software interface for some engine simulation system. He walked me through whatever chemistry I needed to understand, and the rest was history. I still remember him trying to explain the Chapman-Jouget condition to me and emphasizing that we were working with detonations and not deflagrations!

I still wonder how much I did know back then–it’s all a blur now. Too bad I can’t be both an eye surgeon and a rocket scientist.
