That is John Preskill, the Richard Feynman Professor of Theoretical Physics at Caltech.

He gave a talk in 1959 at Caltech, which was called There's Plenty of Room at the Bottom, and what he meant by that is that there was an opportunity by making our technologies smaller and by making smaller devices to take advantage of the potential to put a lot more devices in a small volume of space, and he recognized that that would be important for computing.

He even suggested that we should eventually be able to manipulate atoms one at a time, grab a hold of a single atom, do what we want with it.

Here is John Preskill.

I think there has been a surge in skepticism about science and about scientists and their motivation.

I don't think scientists should expect people to just believe what they say on the basis of authority, but I think there is an unhealthy level of skepticism about the motives of scientists.

A lot of people go into science, and it's not because it's the most lucrative career they could have.

They go into it because they want to discover things, and they want to share that knowledge with colleagues and with students and with the world.

Richard Feynman had become the kind of scientist that inspired other people to do science.

I'm John Preskill.

I'm a professor of theoretical physics at the California Institute of Technology.

I am the Richard P. Feynman Professor of Theoretical Physics.

I grew up in the Chicago area.

My interest in science, like for a lot of people in my generation, I was, you know, a kid in the early 60s and I was fascinated by the space program.

But actually Feynman had an influence on me when I was very young.
