Worlds First Plastic Magnets

CrashRide writes: "Came across this story at www.sciencedaily.com about the worlds first plastic magnet. Not too useful for day-to-day stuff yet -- 'magnetic polymers are unstable unless they are in an oxygen-free environment at temperatures below 10 degrees Kelvin (more than 440 degrees below zero Fahrenheit; absolute zero, the point at which all motion stops, is zero degrees Kelvin)' but the possibilites are interesting."

*Degrees* Kelvin?

[Red Moose]

Just to be bitching, there are no "degrees" Kelvin, they are just called Kelvin. It's just "below 10 Kelvin". At least that's something I remember from 10 years ago........

No, actually, you're wrong. 10 Kelvin is a specific point on the temperature range. It's not a quantity. As I learned it, you say 10 degrees celsius when relating a temperature, since 10 degrees celsius is a specific temperature. But when relating the difference between two temperatures you say "A is 10 Celsius degrees higher than B." A Celsius degree is a difference in temperature. A degree Celsius refers to a specific temperature.

So 10 Kelvin is correct. To say a difference in temperature with kelvin you might say "60 Kelvin is 10 kelvins more than 50 kelvins."

And just for the record a Celsius degree is the same as a Kelvin (difference in temperature). The Kelvin and Celsius scales are the same, except Celsius is shifted up 273 Celsius degrees.

some similar research at Ohio State

A professor of mine at Ohio State has been doing research in the same field as well. Here's a link to his homepage. here Dr Epstine has also been working on the conducting polimers as well.
