To multiply two numbers, he sees each number’s shape floating in his mind’s eye. Intuitively, and without effort, he says, a third shape, the answer, forms in the negative space between them. “It’s like a crystallization. It’s like developing a photo,” Daniel told me. “Division is just the reverse of multiplication. I see the number and I pull it apart in my head. It’s like leaves falling from a tree.” Daniel believes his synesthetic shapes somehow implicitly encode important information about the properties of numbers. Prime numbers, for example, have a “pebble-like quality.” They’re soft andTo multiply two numbers, he sees each number’s shape floating in his mind’s eye.

This is the most fascinating thing. What can we learn about numbers and advanced math from this mind?
