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...
