About OC Math Circle

 

The Orange County Math Circle was founded in 2007 by math enthusiast Johnny Li (Harvard University, Class of 2015) to bring his experience from San Diego Math Circle to share with more students in his hometown.  Please read Orange County Math Circle, A Service Learning Project by Dr. Michelle Muratori of Johns Hopkins University to learn more about its history.
 
Johnny also published an article titled "Orange County Math Circle: Where Math and Service Meet" in Imagine Magazine, May 2011.

Even those not planning to compete this year are welcome to attend these classes to gain valuable skills and practice. 
 
The next class will be on Saturday, January 26, from 4:30 to 6:30 PM at Concordia University. A registration email will be sent out a few days prior to the event, so please be on the lookout for it. On January 26, we will also have a guest lecturer Noel Galang, a UCI student who will be talking about MC Escher's Drawings, an intriguing subject related to math.
