This is a representation of your brain, and your brain can be broken into two parts. There is the left half, which is the logical side, and then the right half, which is the intuitive. And so if we had a scale to measure the aptitude of each hemisphere, then we can plot our brain. And for example, this would be somebody who’s completely logical. This would be someone who is entirely intuitive. So where would you put your brain on this scale? Some of us may have opted for one of these extremes, but I think for most people in the audience, your brain is something like this--with high aptitude in both hemispheres at the same time. It’s not like they’re mutually exclusive or anything. You can be logical and intuitive. And so I consider myself one of these people, along with most of the other experimental quantum physicists, who need a good deal of logic to string together these complex ideas. But at the same time, we need a good deal of intuitive to actually make the experiments work. How do we develop this kind of intuitive? Well we like to play with stuff. So we go out to play with it, and then we see how it acts, and then we develop our intuitive from there. And really you do the same thing. So some intuition that you may developed over the years is that one thing is only in one place at a time. I mean, it can sound weired to think about one thing being in two different places at the same time but you weren’t born with this notion, you developed it. And I remrember watching a kid playing on a car stop. He was just a toddler and he wasn’t very good at it, and he kept falling over. But I bet playing with this car stop taught him a really valuable lesson, and that is that large things don’t let you get right past them, and they stay in one place. And so this is a great conceptual model to have of the world, unless you are a particle physicist. It’d be a terrible model for a particle physicist, because they don’t play with a car stop, they play with these little weird particles. 2:09
