You can't exclude the middle.** There's not just "This and its
Opposite" - there's always something inbetween... The Trifoil
knot (shown here differently than its usually "3 ring" style,
which looks all mystical and stuff) has something called
chirality.* Fancy word.* It means "handedness". Put your left
hand and right hand together.* Try to get them to be the same.*
Sure, you can get them to face each other, but.. stick one on
top of the other.* No matter how hard you try, you can't match
them up so that you have two left hands or two right hands. And
that, my friends, goes down deep into the core of ... well ...
everything.* Lots of things can match up and become the same
thing in exactly the same way. But ... not if something has
chirality.** That's what "symmetry breaking" is all about.* Your
left and your right are different and... that's that.* They're
different. Things spin right and things spin left. and you can
twist and turn and flip it around - no matter how hard you try,
you can't turn one into the other without a mirror. I like this
image because it also doubles as an excellent pattern for
cleaning a window or a room with.* I discovered it the hard way
when I was going through "What's the most efficient way to do
everything?" phase last year, only to find out tonight, that
it's something far cooler than just a great way to clean a whole
window in a single, smooth swipe. Notice: It's over-under-over.*
Or under-over-under. If this is over your head, don't feel bad.*
It's over the heads of some of the toughest thinkers out
there... people way smarter than I could ever be.... and yet...
it's not so hard really, as long as you're willing to have a
left-hand and a right-hand that are forever mirrors yet never
entirely the same.[1]330px-Trefoil-non-3-symm.svg
