Reference

Today I was sitting and studying the physics of electricity and I noticed a pattern. Everything I have learned so far in electricity up to resistance has been reliant of potential difference. Potential difference is an electric force that drives an electric current between two points. Every other concept I have learned so far in electricity including previous topics are based on this fact. Potential difference is a kind of a reference point to learning new ideas in electricity.

Reference and relative points are everywhere around us. It gives us a perceivable way of understanding our surroundings. For example, when I am sitting in my family room at home I see a table with an elephant, a candle, and a ceramic bowl all around similar size and color. As a matter of fact, everything in this room around me is of similar size, shape, and color giving each a viable reference point to one another.

This made me think. If I were to sit in a room with absolutely nothing and infinitely white in all directions than I would have no reference point at all and it would be the same exact thing as being blind. On the other hand, if there was a black dot in a certain distance from me in this infinitely white room then it would act as a reference point that our memory would constantly revert to when lost. This is why I believe that we remember landmarks instead of street names when we drive in foreign places because they act as reference points to our relative base point(where we spend most of our time). This also gives me an vague understanding of our visual intuition and the way we perceive objects. If I were to draw a cube with lines then it would look like this:
It appears as though is box is a three dimensional object but in reality it is two dimensional. There are certain points in this object that are eyes perceive in reference to other points that cause this object to trick our brains to be three dimensional. Our brains automatically see this third dimension due to the accurate relativity of the lines.

Objects that are out of proportion are hard for our brain to perceive. We are somewhat of learned creatures. Whenever we walk into an office with a abnormally large pencil, our brains are immediately shocked about its size. Most objects we observe are already hardwired into our memory and fast conclusions are made by our brain to make a decision on what they are. Hence the quote "Its a bird, a plane, superman!" Our brain at first immediately looks up into the sky and comes to the conclusion of a bird then a plane.
