Our founder, Marie, used the M from their name and the M from their spouse's name (shout out to Matt) to create a logo evoking a stylized open book. With this logo in hand, the name Sigma Three i.e. "𝚺 3" was created. Which happened back in 2010, before any of these Gen Alpha kids were even born. So get off our backs about it. It's classy. Very Ohio.

In 2026, Marie was shamed and pressured into updating the logo by actually using graphic design software and not just manipulating graphics in a word document. Actually, we're all pretty happy about the new look and think it was the right time to make a new logo to go with our new website.

Of course, the book wasn’t just a convenient shape for a logo. Books are, frankly, the whole reason this endeavor started in the first place. From a very early age, Marie learned that if you were curious about something, the solution was simple: go find a book about it. Or several books. Preferably from multiple libraries. Fiction, non-fiction, science fiction, history, science, mythology, astronomy, archaeology—if it existed, it was worth learning about. Childhood (and adulthood, lets be real) were spent wandering library stacks, chasing strange questions, and researching things purely for the joy of understanding them. To this day, the best part of any museum visit, lecture, or chance conversation is walking away with a list of new topics to look up or books to read. So yes, the logo is a book. Of course it’s a book. What else would it be?
