palegray.net writes "Wired News brings us an article about brain scanning systems that can accurately tell what you're looking at by analyzing your brain's electrical activity. Using a database constructed of readings taken on test subjects who were shown thousands of photographs, the system works in real time to decipher what you're seeing. Naturally, there are some ethical concerns over some potential applications for this technology. Definitely a new twist on "input devices.""
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
