A Conversation for Superconductivity

Under the "Types of superconductors" you say they made a superconductor which functions at 130K, about 140 degrees. I think you missed out the negative sign on that 140.

Actually he was originally correct, negative 140K would be below absolute zero, which is impossible to achieve.

No, 130K is 130 ABOVE absolute zero. -140 degrees (missed out the scale here, should be minus 140 Celsius or Centigrade) is also 130 degrees above absolute zero. No inconsistency, just two things missing: the minus sign and the scale. 140 degrees should say "-140 Centigrade".

I know, I know! smiley - winkeye I told the editor that the minus sign had somehow been missed out in the editorial process. For the record: -130 C IS 140K give or take a degree or two.

Yup, I just came down to mention that too... smiley - smiley

Ah well, it proves that people are reading that far down the article without getting bored and going elsewhere....smiley - winkeye

Yup - it's an excellent article! The first time I've seen a readable explaination of what a "Josephson junction" is... smiley - ok

Somebody at IBM did actually make a Josephson computer yonks ago, but increases in the speed of silicon, combined with the hassle in keeping the bloody thing cold enough, meant the project got junked. Hopefully we'll hear a lot more about them when eventually someone invents a room-temperature superconductor. It'll make my office cooler, at least.

Not necessarily... I can see them combining Josephson junction technology with stacked Peltier devices, producing chips which are chilled internally but run as hot as present chips (or hotter!) on the outside... smiley - biggrin

Well they'd better get some better air conditioning 'round here first!

yeah, 130 K is only a degree (or seven...) off from 140 C. 0 degrees Kelvin is -273 Celsius.

OK: I put the minus sign in the original, when it had been edited it went missing. Everyone makes mistakes, even TPTB. High temperature superconductors work at temperatures of up to 130K. This is about MINUS 143 C.

Hope this clears things up.

All is clear, but the error is still there - perhaps mentioning it to the editors would be again worthwhile..
great entry though smiley - cheers vp

I just discovered that one too. Great article by the way!
