Hello, in 1911, the Dutch physicist Haika Kameling-Honors made a remarkable discovery

that nobody predicted and that non-consens fully explained.

It's called superconductivity.

When he lowered the temperature of mercury close to absolute zero and run an electric

current through it, he found not that it had low resistance, it had no resistance.

A century later, and this has already been applied to make MRI scanners and to speed particles

through the large Hadron collider and may perhaps bring nuclear fusion a little closer,

a step that would be world-changing.

Let me discuss superconductivity, our Nigel Hussie, professor of experimental condensed

matter physics at the University of Bristol and Radboud University.

So sheatress Sebastian, professor of physics at the Kevin Dishnaboratory at the University

of Cambridge and Seben Blondell, professor of physics at the University of Oxford and

fellow of Mansfield College, Oxford.

Seben Blondell, can you take us into the laboratory of Kameling-Honors?

What had you been working on to get to this point?

Well Kameling-Honors was on a scientific quest to understand how various gases can be liquefied.

The issue is that we know that water is a liquid, but nitrogen is a gas, and why is that?
