The total number of particles in the whole universe is usually estimated to be around 10^80. These guys claim that the storage of the brain is 10^8432 bits. That means that my brain has around 10^8352 bits of storage for every particle in the whole universe.
I thought I was feeling smarter than usual this morning! Possible explanations: 1) The quote to totally wrong the the "^" should be a "," ? 2) They got confused and thought it was 1 April 3) They are actually doing research into just how flaky AI researchers really are and how easy it is to publish mathematical nonsense in "Mind and Brain" Journal 4) The "scientists" somehow managed to get their PhDs without understanding how numbers work 5) They concluded that the brain is really analogue and so they worked out the volume of the skull at the Planck scale (actually that doesn't work either as the Planck length is far far far to large at 1.6 x 10^-35 m) and so on... Does anybody have a better explanation? Shane --- "Amara D.
