Sun in common-sense shocker

Sometimes I worry about being too negative on Just A Theory. With all the examples of media failings I write about, it’s easy to let the good ones slip past unnoticed. As such, I thought I’d congratulate The Sun’s Dr Keith for his recent article on misused medical terms. He informs us that we probably don’t have the flu (it’s a cold), there is no such thing as a nervous breakdown, and most of us are rarely “shocked”, in a medical sense.

New hope for Copenhagen

Later this year thousands of people will descend on Copenhagen to try and come up with a new global agreement on climate change. The United Nations, in conjunction with the International Advertising Association, have launched a campaign to re-brand the conference as Hopenhagen. The idea is to move from “coping” with climate change to a “hope” that action can be taken. A silly bit of marketing? Perhaps. But if it gets people talking, it’s probably a good idea.

Check this out. It’s awesome

“But what is it?” I hear you cry. Created by Japanese artist Sachiko Kodama, the strange substance in this art work is a ferrofluid. These odd liquids combine tiny magnetic particles with water or oil, and a surfactant, which prevents the particles sticking together. Ferrofluids react in the presence of a magnetic field, creating the wonderful structures in the video above.

Whilst they do have their practical uses, like forming a liquid seal in computer hard drives or marking areas of the body in an MRI scan, I think you’ll agree that just looking cool is good enough.
