Science and engineering majors have such an exciting range of options open to them after graduation. Sometimes, we don't realize how wide this range is until we accidentally stumble into a job that seems unrelated to our major, yet reveals our true calling. This is certainly how many people with technical degrees end up as writers. Perhaps technical or science writing is for you, too.
Technical writers enjoy breaking down complex processes into their component parts.
They are compelled to cut through to the heart of the matter and sift out the unimportant from the essential. Science writers enjoy explaining complex processes in ways that turn on the light of conceptual understanding in the minds of readers who haven't had the luxury of rigorous scientific training. I've dabbled a bit in both areas but discovered that, unless you're Timothy Ferris, technical writing is much more likely to pay the bills. My years in college took me through stints as a chemistry major, a physics major, and a biology major. I loved too many different areas of science to choose only one.
