Let's nourish my inner geek today. This'll do it. 3-D is something I find tricky to conceptualise. I had a squint when I was younger and though it was corrected when I was four an optician told me that my eyes hadn't adjusted properly. They got quite excited by my oddness when testing me. Even though my left eye has normal vision I rarely use it. For the most part, it's as if I'm blind in one eye. That means I see the world in 2-D. My IQ is pretty peachy is some areas but in the visuo-spatial domain I'm near the bottom of the class.
So I'm in awe of Robert Lang, origami artist and physicist. Don't you just admire people who have more than one talent in what seem to be unrelated fields? I love the way this man thinks outside the box and has transformed paper designs into engineering solutions.
