little happier. The famous mathematician GH Hardy wrote a memoir called a Mathematicians apology.

In it, he tells a story about a visit he made to Serena Vasa Ramanajan, another brilliant

mathematician with whom he collaborated. Ramanajan was in the hospital, dying, and Hardy went to see him.

He recalls. I remember once going to see him when he was lying ill at Putney. I had written in

TaxiCab number 1729 at Remark that the number seemed to me rather a dull one, and that I hoped it

was not an unfavorable omen. Oh no, he replied. It is a very interesting number. It is the smallest

number expressable as the sum of two cubes in two different ways. Ramanajan was correct. 1,729

is a number that can be written as 1 cubed plus 12 cubed and 9 cubed plus 10 cubed. There's no

smaller integer that can be written as the sum of two cubes. To this day, this kind of number is

called a Hardy Ramanajan number or a TaxiCab number. Only six other TaxiCab numbers have been found.

I love this story partly because it's such an odd conversation to have, the kind of small talk

that only two mathematicians when finding themselves having. And partly because it shows that a

curious, engaged mind prepared with knowledge can look out at the world and find fascination

in situations that to others seem quite dull. I'm Gretchen Rubin and I hope this makes your week

a little happier.
