cutting-edge technology of the colossus computer. So it seems fitting that in his talk

Gordon looked for the connecting threads between then and now, between maths and machines, computers

and people.

I always think it must have seen to build up's colleagues, and it still seemed to most of us like myself who aren't mathematicians, like magic, when he said, I've got it, I've got it, I've worked

it out, when someone can perform the kind of mathematical feat he performed during the war,

it looks like magic. It's not magic, it's maths, but it's something remarkable. And I think the connecting

thread that I wanted to talk about between then and now is maths and machines, computers and people,

the relationship between the two and how they work together. I started, when I wrote about this,

because I thought the first computer came along at Bletchley during the war, and then I read a bit more and realized it was a person. And the computer's
