The Greek philosopher Plato is well known for his allegories and metaphors. Of particular interest is his Allegory of the Cave, which appeared in The Republic, written around 380AD. In it, Plato describes a group of prisoners which are chained to a wall within a cave, and have been all of their lives. They have no direct interaction with the world outside of the cave. They only know of the world via shadows that are cast on the wall opposite of them. For the prisoners, the shadows are their reality. Though you and I know the shadows are only a very low-resolution representation of that reality.
Theoretical physicist Steven Weinberg, a Nobel Prize winner who works out of the University of Texas in Austin, once likened himself to a prisoner in Plato’s cave. We are forever chained to this cave by the limitations in measurements we can make and experiments we can perform. All that we can know are shadows of the reality that exists in the sub-atomic world. We can see the shadowy figures lurking in our math and as wisps of misty vapor trails in our cloud chambers. We attempt to pierce the veil with the power of our imagination and draw nifty looking charts and animations depicting what our mind’s eye thinks it can see. But in the end, we are all trapped in a cave… staring at shadows. Reflections of a reality we can never truly know. |

Sounds like Steven Weinberg's problem to me.
If you need fear to enforce your beliefs, then your beliefs are worthless.

" All that we can know are shadows of the reality that exists in the sub-atomic world " Same as the other side of the spectrum...Deep Space. The very large and the very small are indeed a mystery.

Magicfish, this is an interesting allegory and one I like to roll around my mind. Dimentions, if we lived in a world of two dimentions, what would an apple look like? Certainly we could not see it as an apple, lacking the ability and knowledge of the third dimention, so, perhaps we could prove it exists using mathematics or a two dimention version of physics, or we may even be able to see a vague shape or shadow. The point is we'd never truly be able to "see" the apple without knowledge of a third dimention, and a way to transition to a three dimentional reality. How is that achieved? Could it be death? Is dying our way to transition to the fourth dimention? What would the fourth dimention be? Time? Light? Energy? Gotta admit this is waaaay more fun to contemplate when stoned.

@ Danny!
In words of one syllable: Yes! Me too! BTW Bill: "dimensions" is spelled with an "S" (dimenSions). But then, how should I know? I've never been stoned.

Field of Vision ... An invisible hole in the middle, all tingly around the periphery and lots of negotiating between the eyes. Stranger than Escher.

We're still learning...evolving.
What we can truly know is not known. Weinberg should have more confidence in us.

It gets strange when you look at a two dimensional slice when the sphere rotates about various axes. For example: consider the cross section (in the plane of the circle) of the sphere as it rotates about an axis which passes through a point on the "visible" circumference. What would a circle make of that? If you want "troublesome" - consider the circle as having a differential thickness in three dimensions. Now look at neighboring planes and what kind of thing it might be to get that circle to move between planes.

If it requires my being smart or thinking probably not.
