Ted.com is so interesting.
I watch three part of them.
One part is a real contest, and two part is show.

1. The first one is a show. It's about a MATHMAGIC show.There is a person ,he can calculate the square about the number. In that show he calculate of two digit, three digit, four digit, even five digit's number.It's really surprising me. That man want to inprove he can calculate correct.He invite four people bring the calculating . Help him to calculate.I don't know how he did it. Iwant to o mit ,too.
2. The secone one is a man doing B-box. He making himslef is like to playing turntables, and make that voice of himself. It's interesting ,too. Isn't his mouth tied? It's so quick for people .And he even can make alot of voice we think just can make from machine.It's too difficult for me.I thin; it's too difficult to a lot of people.
3. The third one is a little likeshow but it's have speaking. It's talk about the piano. They have a machine to control the piano. They device that machine under the fingerboard.They boardcast the music.then the piano's fingerboards are playing of theirslef.It's not just can listen. It's look like there is a person is just sitting in front of the piano and playing the piano.It's very wonderful and unbelievable.I can't find any word to describe my feeling.I'm too excited.
