Name: Maggie Pang

Birth Year: 2006

Additional Information

My mathematical interests include group theory (or any mention of symmetry or lack thereof), knot invariants (or topology in general), and all sorts of other interesting geometry (tiles, slices, algebraic varieties, etc.). Although various objects take something like 6 hours to fold, I very much enjoy origami and the math that goes behind things like polypolyhedra, tessellations, crease patterns, and auxetic surfaces.

I'm not insane.

Looking forward to competing at SLC again this year! I've participated in a variety of other competitions in my school career, including the Bow Seat Ocean Awareness Art Contest last year, and doing the Junior Breakthrough Contest three years in a row, submitting a high effort digitally hand drawn animation each time. Furthermore, I've participated in business and other STEM competitions, including attending the national FUSE business competition in eight grade. In my free time, I enjoy volunteering at a hospital and utilizing my marketing skills in general. :)

I tend to gravitate towards the social sciences: history, geography, economics, politics, and the like. Maybe that's because most of my family are MPs.
