ESP Biography
HERNG YI CHENG, Student, teacher & researcher of math & origami.
Major: 18 College/Employer: MIT Year of Graduation: 2018 

Brief Biographical Sketch:
I love learning about cool and beautiful math. I've also researched the mathematics behind origami, the art of paperfolding, for more than five years. I can't shut up about my favourite topics, so I share about mathematics and other subjects through talks, workshops and my website: herngyi.com Past Classes(Clicking a class title will bring you to the course's section of the corresponding course catalog)A10483: Fold an Origami Box! in Spark 2016 (Mar. 12  13, 2016)
Paper airplanes not enough for you? Origami is the art of paperfolding, and it’s great because you can fold awesome shapes and gadgets from one of the most common materials around! Join us for some finger folding fun; you too can can create something cool, with your own hands. No prior experience necessary.
M10049: History of Ancient Math in Splash 2015 (Nov. 21  22, 2015)
Math has come a long way, from counting sheep with pebbles to equations that govern the universe, and much more. Over the ages, various civilisations have pushed the boundaries of mathematics further, and fundamentally changed the way we see math. What is a number? What kind of space do we live in? Can we know everything? What can we know for sure? What is math used for? What is truth? Let us trace the development of math through antiquity (~2600BC to ~1600AD) and see the math of today in a new light.
M10050: History of "Modern" Math in Splash 2015 (Nov. 21  22, 2015)
Where did all of the math of today come from? In the last few centuries the field of mathematics exploded through the development of symbolic notation, crossfertilization with physics, challenging our ideas about the infinitely large and the infinitely small, not to mention developing countless new fields of math. Why did people need to invent these ideas? Let us survey the history of "modern" mathematics from about 1700 to today, survey the great revolutions, and see the math of today in a new light.
M10056: (Geometric) Transformers: Now in 2D! (And Black and White) in Splash 2015 (Nov. 21  22, 2015)
Given two shapes of the same area, can one be cut into pieces and rearranged into the other? For a century, puzzlemakers have challenged each other to solve such "dissection puzzles" using the fewest number of pieces. Try your hand at one! http://www.herngyi.com/blog/geometricdissectionpuzzle
This lecture will cover basic techniques to create and solve dissection puzzles, some of the math behind them, and special types of dissection puzzles like 3D or hinged dissections.

M9188: Number Patterns in Symmetric Shapes in Spark 2015 (Mar. 14  15, 2015)
What do floor tiles, wallpaper and honeycombs have in common? They are formed by repeating a fixed pattern in an orderly fashion, which adds to their beauty. That beauty is shared by some symmetric 3D shapes formed from repetition, such as cubes.
As it turns out, the prettiest shapes that are full of symmetry can be cleanly described using just a few numbers. In this lecture we'll also look at some interesting patterns within those numbers.

M8813: Stretch, Twist, Squash in Splash 2014 (Nov. 22  23, 2014)
Ever heard of the joke that mathematicians can't tell the difference between a donut and a coffee mug? Well, now you have. Believe it or not, a mug made of *very* elastic rubber can be bent into a donut. Draw it out and see!
Topology is the study that bends shapes into one another. In this lecture we'll look at the bending of sheetlike objects called "surfaces". We'll conjure up and scrutinize some strange surfaces. Some surfaces appear to be different but are fundamentally the same; how do we classify them?
