BigLug writes "The ABC reports that the Australian Defence Force (ADF) has launched a dedicated online games site as part of a plan to try to recruit more young people to the armed forces.

ADF director-general recruiting Brigadier Simon Gould says he is confident many of the users will play the games and then check out the ADF recruitment page and consider a career in the Army, Navy or Air Force.

BigLug writes "In a study to appear in Nature Materials, two experts in non-linear dynamics, Gert van der Heijden and Eugene Starostin of University College London, resolve the Moebius Strip algebraically.

From the ABC (Australia):



What determines the strip's shape is its differing areas of "energy density," they say.

"Energy density" means the stored, elastic energy that is contained in the strip as a result of the folding. Places where the strip is most bent have the highest energy density; conversely, places that are flat and unstressed by a fold have the least energy density.
