Mucking about Geometry?

Question

I have found that when turn a paper back to front with a geormertic shape ie a triangle enclosed with circle, the revese can be idenified. So where does reality begin + where dose it end. Is it mirror image or what?

Answer 1

I have a pair of those interesting deep-dish-shaped double-domed parabolic mirrors from Edmund Scientific, the top one sits upside-down on the bottom one, and the top one has a hole in it. So when you put something inside it, and move away at an angle, an image of the object appears to be sitting above the top dish. I ask people, "Hand me that little pink pig sitting on that dish". They see it, reach for it, pick up nothing, reach for it again, and see their fingers apparently pass right through a solid object.

What is the reality there? My eyes tell me there's a little pink plastic pig sitting on the top of that dish. Yet when I try to pick it up, my fingers pass right through it. But then I distort the mirrors a little, and the pig blurs in an odd way that lets me see that he's actually a reflected image from inside the unit. And if I understand optics sufficiently, I understand that it is possible, with certain arrangments of parabolic mirrors, to erect "real" images (versus the more common "virtual" images that we see in most mirrors and lens) of objects, and even design and build versions of my own, with the effects and capabilities fully determinable in advance. That's reality.

Reality does exist. Granted, we have a limited and distorted view of it due to the limitations of our senses, but it does exist. For example, this desk in front of me seems like a solid object. But in truth, my view of it is limited by the fact that my eyes are not able to resolve the electrons orbiting the nuclei that make up the desk, and that the vast majority of this desk is vacuum, therefore the fact that, when I touch this supposedly-solid desk, what's actually happening is that the electrostatic field generated by the electrons of the desk are exerting a force against the electrostatic field of the electrons orbiting the nuclei of the atoms making up my fingers. There are no "solids" touching anything, just fields pushing against each other the way 2 magnets can push against each other.

To me it looks like reality begins immediately outside your eyes. All is reality. The only place it ends is inside your head, when you misinterpret what your limited senses tell you.

Answer 2

All I know is when playing cricket the ball that I see is the one I catch or miss.
Why would I want to experiment with the ball that I catch, not be where I want to be, when catching it?
It's science fiction gone mad.
Get a grip lads.

Answer 3

I just tried this. Isn't one simple a reflection of the other? This must come under transformation of shapes. Both are real.
