I had the opportunity to hear Wes Fryer keynote today at the 1-1 Laptop Conference in Chicago. He used a stat that I have heard before and have debated a little. The idea is: "What we see travels to the brain 60X faster than what we hear" We discussed it afterward because I have recently looked at that information for another presentation that I was working on. I think it should actually be: "At any one time 60X more information can travel to the brain from the eyes than from the ears" Did some research tonight to confirm my off the head numbers today and here is what I found... Optical nerve fibers = 1,200,000 Several spots on the web - here it is from Wikipedia: http://en.wikipedia.org/wiki/Optical_nerve Auditory nerve fibers - 20,000 - 30,000 depending on the source wikipedia has it at 30K At 20K you get the 60X number 1,200,000/20,000 = 60 That would just impact the amount of information that could be carried at any one time.

I found you via a recommendation from Beth Knittle. She had thanked you as part of Dembo's Day 3 of 30 Days to Being a Better Blogger.
