Scientists divide magnetic vortices into collectivists and individualists

Edit Science Daily 01 Apr 2016
In manganese monosilicide, microscopic magnetic vortices -- skyrmions -- may behave as 'collectivists' or 'individuals,' i.e. they are able to create a single structure, or they can also split up individually. Studying the behavior of skyrmions will help to create unique quantum devices based on new physical principles ... ....

Weird But Worked! Vought V-173 “Flying Pancake”

Edit World History Online 15 Mar 2016
Ground testing of the V-173, c. 1942. The disc wing design featured a low aspect ratio that overcame the built-in disadvantages of induced drag created at the wingtips with the large propellers actively cancelling the drag-causing tip vortices. The propellers were arranged to rotate in the opposite direction to the tip vortices, allowing the aircraft to fly with a much smaller wing area ... Diagram of the complicated powertrain ... ....
