Computers! What about computers?

And if I haven't revealed my prejudices already, I think that life has been about molecular computers building electrochemical computers, building electronic computers, which together with electrochemical computers will build new molecular computers, which will build new electronic computers, and so forth.

Why are we using computers to show a student how to solve a problem by hand that the computer should be doing anyway?

It's a computer where the people are the parts.

It could compute. It couldn't just calculate. It could do more.

And so computers, as you know, these big computers, there are now tiny computers.

Let's figure out what this is.

When you run the numbers on a calculator, you run out of noughts.

A currency converter and calculator

It's a molecular computer building an electronic computer.

Computers

This is the One Laptop per Child, the 100 laptop.

Grid computing the power of grid computers is going to be just amazing here.

There is a carbon calculator. Participant Productions convened, with my active involvement, the leading software writers in the world on this arcane science of carbon calculation to construct a consumer friendly carbon calculator.

Perform arithmetic, scientific or financial calculations

Method of calc

Grpn Calculator

Unit of account

It was very hard to calculate from first principles. I was stumped.

And here we are frantically building these experiments, doing these calculations, writing these computer codes.

And at the time, I wasn't really working on computers.

That's amazing parallel and distributed computing power, new design possibilities.

Inputs (resource estimates in euros)

They're littler computers, so the one chip computers, I began to program one chip computers and make objects out of P.C. boards, LEDs.

Histogram calculation...

Scientific Calculator

A Scientific Calculator

Chemical calculator

The tellers will now count the ballots.

And after this I wanted to build a computer out of people, called a human powered computer.

Well, the way we've come up with uses computers but doesn't depend on them.

Jamaica had suffered a 275 per cent increase in the last calculation as a result of a change in the methodology.

You've seen brilliant people devise computer viruses that bring down whole systems.

Even a mobile phone, it's a computer.

Rapid manufacturing is a computer file sent directly from the computer to the manufacturing machine.

Graphical interface to the R environment for statistical computing

We count numbers.

It's not a matter of calculation.

Scientific computing environment

High precision calculator

RF Impedance calculator

But the computer should not just be the glove of the hand the hand should really be the driver of the computing power.

This was a computer assisted instruction system, which in those days ran on a computer named ILLIAC.

And finally, I'm going to get back to that sort of crazy idea about computers building computers.

I think we should be assuming computers for doing the calculating and only doing hand calculations where it really makes sense to teach people that.
