The Nth User

Hi. My username, if you're wondering, is induction-inspired. You'll probably find me on a math-, science-, or meteorology-related article, but I also patrol Category:Candidates for speedy deletion for unspecified reason somewhat frequently and specify the reason based on the provided description in the CSD template. I am currently focusing on improving Wikipedia's coverage of music systems. In the past, I've worked on improving Wikipedia's categorization of chemical compounds, Wikipedia's usage of SMILES, Wikipedia's coverage of acids and bases, Wikipedia's coverage of the peninsulas around the Laurentian Great Lakes, and Wikipedia's coverage of tropical cyclones.
