I remember my first "a-ha" moment. I'm ashamed to say it wasn't until my early teens. But then again, I was amassing the information I needed to fuel the "a-ha" moment. Since then, I've had numerous "a-ha" moments – some not as earth-shattering as others.
One of my guilty pleasures during the workday is to visit ScienceDaily. The Web site has so many interesting stories all relating to science. I guess I shouldn't feel too guilty, I work for Chemical Processing, which is a science-based publication. And ScienceDaily has an area dedicated to chemistry.
