I love music. I have a fondness for Chopin, and I very much like his 'Raindrop Prelude.'

I changed my name because it didn't fit with the way I saw myself.

I'm inconsistent because I'm human.

I remember as a young child, during one of my frequent trips to the local library, spending hours looking at book after book trying in vain to find one that had my name on it. Because there were so many books in the library, with so many different names on them, I’d assumed that one of them — somewhere — had to be mine. I didn’t understand at the time that a person’s name appears on a book because he or she wrote it. Now that I’m twenty-six I know better. If I were ever going to find my book one day, I was going to have to write it.

I would play with numbers in a way that other kids would play with their friends.

When I achieved the European record for reciting pi in 2004, this captured the imagination of Professor Simon Baron-Cohen in Cambridge and he finally diagnosed me with Asperger's that year.

I had eventually come to understand that friendship was a delicate, gradual process that mustn’t be rushed or seized upon but allowed and encouraged to take its course over time. I pictured it as a butterfly, simultaneously beautiful and fragile, that once afloat belonged to the air and any attempt to grab at it would only destroy it.
