Four years after I had begun my first incursion into the research world, I saw myself as a somewhat seasoned student researcher. At the very least, I had some confidence in my research and experimental abilities. But it was not until this year that I realized that through all the lofty jargon and fancy terminology I had been picking up along the way, there was something I had been urgently lacking: the basics.
One of the eye-opening incidents happened just this past summer, when my supervisor asked me to explain to him an optical gas sensing technique known as “2f wavelength modulation spectroscopy.” That day, I had been trying to calibrate a laser that we were planning on using for a methane sensor and had been experiencing some problems. As my supervisor always does when he troubleshoots, he wanted to start from the basics. After all, if we didn’t know how every bit of the sensor worked, how could we figure out the possible sources of problems? But usually he had been the one doing all the explaining, so I was surprised when he suddenly asked me: “Stacey, what is the signal that we’re measuring anyway?”
