Long answer: I am a researcher in photonics. Think electronics, except I deal with photons instead of electrons. I shine lasers at liquids and then look at the scattered light. The light tells me what’s in the liquid, and how much is there.
What got you into homebrewing?
My partner Rob saw a homebrew kit at a grocery store in Vancouver. My Dad is a homebrewer, so I knew what we were getting into. A quick trip to Dan’s Homebrew Shop later, and the hobby has consumed most of our apartment for about 6 years.
