Bristol physicists break 150-year-old law

Oh no this can't be true a CONSENSUS of scientists have agreed on the Wiedemann-Franz law so the science is settled and no further research is needed. (global warming sarcasm)

This is why Al Gore and the other global warming hoaxers are not true users of the scientific method. Science is never settled and is always open to new investigation to prove or disprove hypotheses.

What’s next? Ice-Nine?

purple bronze = Li 0.9 Mo6 O 17

The paper: http://www.nature.com/ncomms/journal/v2/n7/full/ncomms1406.html

This historic discovery is described in a paper published today in Nature Communications.

I would say it was discovered 15 years ago by Kane and Fisher and finally verified experimentally by this group. Not to take anything away from their achievement.

It’s effectively a one dimensional heat sink (and it works better at lower temperatures).

I guess a composite material with trillions of such doped 1D chains ‘baked in’ would act as an effective sink. However: dispersal of waste heat from electronics does seem a better fit than bulk heat transfer from engines.

[Pecos]

And when he says it applies... and only how he says it does....and, by definition, it never violates the laws of physics, even if it actually does.....

Thanks. I did a search on ‘purple bronze’ and came up blank.

It would seem that there is no bronze in purple bronze.

I thought this was going to be about opening a bootery on Sunday.

It's not necessarily the case that it will apply in all situations.

Laws are not descriptions. They are explanations. The LAW predicted that action A would happen under a certain set of conditions. Action A did not happen. Law violated.

[Marie Antoinette]

Interesting.

[antiRepublicrat]

We have plenty of other laws with caveats, they don’t work in this or that situation.

[stuartcr]

alchemy...

[Persevero]

“A natural law or physical law is a description of observed regularities of behavior. It’s not necessarily the case that it will apply in all situations. And it’s certainly not true that there are “laws” that physical systems must obey. “

So true, but when we use the shorthand word “law” most people think of it as a settled, unchangeable thing.

[NonValueAdded]

Unpossible, that was Settled Science^™.

[Hatteras]

Oh no... what’s that poor girl getting into now?....

[Eagle of Liberty]

We have plenty of other laws with caveats, they don’t work in this or that situation.

Then the law changes and that is fine. What I simply stated was that the experiment with the purple bronze violated the existing defined law.

Thanks decimon. Pooper cares ping.

purple bronze, a metal with unique one-dimensional electronic properties, indicate that it breaks the Wiedemann-Franz Law

Danged nanny-physics laws, anyway.

.... the Wiedemann-Franz law has proved to be remarkably robust, the ratio varying at most by around 50 per cent amongst the thousands of metallic systems studied.

Close enough for government work.
