It's hard for me to believe, but Math3ma is TEN YEARS old today. My first entry was published on February 1, 2015 and is entitled "A Math Blog? Say What?" As evident from that post, I was very unsure about creating this website. At the time, writing about mathematics seemed very niche — though, I guess it still is — and the thought of sharing my musings publicly was quite intimidating. But as I mentioned in that first article, I started Math3ma simply as a study tool for learning graduate-level mathematics. (Hence the name: "mathema = lesson" in Greek.) And yet I had lots of doubts about whether my articles would resonate with anyone. So the tone in that first article was pretty apologetic. Needless to say, I've been amazed by all that's happened in the past ten years because of Math3ma. Thanks to all of you who've visited the site over the years!
