Authorship and Insect wings

I went to two talks today. The first one talked about using statistical analysis, principle component analysis, and singular value decomposition, to be able to tell if it’s the same or different author compared to other text that you ran through the math by computers. It’s pretty neat, actually, though the talk was less technical than I’d like. The guy did analysis on the original Hebrew and Greek text versions of the Bible to determine whether it was probable that there were different authors under the same name. There’s other things that you can use this for, some invades into privacy, and others don’t. You can also use this to analyse source code in order to determine whether it was the same author that wrote something, and whether the person likely wrote code in other software.

The second talk was much better, quite neat, and still on going. The guy was a much better speaker, and he talked about micro air vehicles that mimick the use of controls and aerodynamics in wing design in insects. The problem is more complicated than you can think of first hand, but the most interesting conjuncture that he had was that it was a sensor-rich feedback control system, rather than a controller-rich feedback control system.
