The volume of a 10" pie tin is exactly the same as 2-7" pie tins.
Here's an interesting fact:
Functionally, the human eye is like a pinhole camera. Anyone who has used a pinhole camera knows that the image produced is flipped, because light travels in a straight line. Thus light reflected off the top of an object, as it makes it's way to the pupil, must be traveling on a downward path, and thus end up at the bottom of the retina, just as any light reflected off of the bottom of an object must be on an upward path, and thus it will in turn end up at the top of the retina. So what does this mean? Everything you see is flipped.
So why don't you actually see it that way? Perceptual adaptation. The human brain processes the information so that you see it properly. In essence, your brain takes the faulty information and lies to you in order to correct it.
In the late 1800's experiments were performed involving specially designed reflective glasses which would flip everything seen. Essentially this caused the eyes to convey the correct image to the brain, which the brain still reinterpreted, thus causing the wearer to see everything reversed... but only for a time. After about five days the brain corrected for this, causing the image to, again, appear right-side-up even though wearing glasses which were specifically distorting what was being seen. After several days wearing the glasses when they were removed it could take several hours for vision to return to normal.
Now, really, how much do your trust what you see knowing that?

Science be fucked, man.
You're not going to sleep tonight, are you?
That's most nights. Chronic insomnia. I don't need weird thoughts to keep me up. Or... maybe I just have enough weird thoughts that's a regular occurrence. :dunno:
I think we might actually be the same person...

Hey, don't you make fun Dirk. That pie tin thing was demonstratd to me by a man that has developed the knowledge of such things. Well respected by his peers and a model to those that have followed in his footsteps for 44 years. Gallagher.

When I was in my early teens, I used to get bad nose bleeds when I had a cold and the air was dry.
One time it just wouldn't stop, so I went to the hospital and the first thing the doctor asked was if I had used cocaine and he needed to take a blood test before doing anything, and would have to report it if the test was positive for cocaine.
I agreed and the tests were negative, but all he did was stuff cotton in my nose and told me to hold my head back until it stopped bleeding.
There's some facts in that anecdote.
