This is perhaps one of the most amazing videos I’ve every watched on the Internet. I was literally left speechless. I can accomplish certain small feats of mental math, but this is absolutely unbelievable. Arthur Benjamin shows us some inspiring abilities of the human mind. I’m sure he has spent a fair amount of time learning his methods, and that to him his abilities are perfectly normal (in some sense!), but it’s great to watch someone with this talent. I highly recommend watching the video in its entirety.

Hi,
I was not much surprised at all when I saw this, since I already was aware of the fact that there are people with these calculation skills. I was though impressed how quickly Benjamin was able to answer every question he was asked during his performance, without even failing a single one of them. I’m asking myself: “Why didn’t I have a mathematics education more similar to mathemagics?” and “Why is our education system like this?”. It’s seems to me that mathemagic might be the key to make maths more intuitive and pleasant to everybody, especially students who dislike this subject.
Art Benjamin is a cool guy. I took a class from him when I was as freshman at Harvey Mudd College, so I got to see him do some spiffy things in class.
