Donggyu Yoon

A man who will change the world

I am a young Korean student. As I am teenager, I have so many curious things about the world. I like to discover a new thing. And grow up my self in my health, my brain, my knowledge.. I will be happy, if I can join in Korean Science School. I am discovering the question, which is simillary called '3x+1'. Though it is so hard, but I will do my best on it. Em.. I gave up it!
