Céad Míle Fáilte ~ A Hundred Thousand Welcomes!

Here we seek a rest in the shade, some cool water and a little kindness. This blog is dedicated to peace, truth, justice and a post- industrial, post-petroleum illumined world in spite of all odds against it. I very much like the line about the ancient knight (see poem below) "His helmet now shall make a hive for bees" It is reminiscent of "beating swords into ploughshares" a sentiment I heartily approve of. Thank you for visiting ~ I hope you return!

Cappuccino Superconductors

I just can't resist a good geek story. (This is an eclectic blog, after all!) From Science Daily.
How cool is this?

Also, I think someone should name their Italian rock band "Cappuccino Superconductors".

QUOTE ScienceDaily (Jun. 11, 2008) — To see the latest science of type-I superconductors, look no further than the froth on a morning cup of cappuccino. A team of U.S. Department of Energy's Ames Laboratory physicists and collaborating students have found that the bubble-like arrangement of magnetic domains in superconducting lead exhibits patterns that are very similar to everyday froths like soap foam or frothed milk on a fancy coffee.

The similarities between the polygonal-shaped patterns in conventional foams and "suprafroths," the patterns created by a magnetic field in a superconductor, establish suprafroths as a model system for the study of froths.
"There are certain statistical laws that govern the behavior of froths, and we found that suprafroths satisfy these laws," said Ruslan Prozorov, Ames Laboratory physicist and primary investigator. "We can now apply what we know of suprafroths to all other froths and complex froth-like systems." UNQUOTE
