I am a big fan of pictures. (No, I didn't mean pitchers. Babe Ruth was most remembered as a hitter but he did, indeed, begin as a starting pitcher for the Boston Red Socks close to 100 years ago.) I really meant pictures, as in photographs.
So many things can be known but not really experienced without seeing. Maybe this is not true for everybody and stems from the fact I am quite a visual learner. I knew, of course, of this famous baseball player as a concept. It wasn't until I was looking online for pictures to add to Pinterest that I really noticed what he looked like. Having an image to connect to a set of ideas seems to make the whole concept a lot stronger.
