In Jonathan Swift’s immortal tale the central character Gulliver is brought to the land of Brobdingnag. It is written that he was repelled by the women of that land. They were monstrous in size compared to him. Their faces when magnified so much skin pores seemed to his scrutiny as moon craters! Matter of size brought about this change naturally. If we were to see as an eagle our eyes would require the size of an orange. To sum view of our world is limited by our human-ness. As a result our sense of beauty is affected; so must our understanding.
Heisenberg’s Uncertainty Principle states that it is impossible to know both the exact position and the exact velocity of an object at the same time. However, the effect is tiny and so is only noticeable on a subatomic scale.
Light can be considered as being made up of packets of energy called photons. To measure the position and velocity of any particle, you would first shine a light on it, then detect the reflection. On a macroscopic scale, the effect of photons on an object is insignificant. Unfortunately, on subatomic scales, the photons that hit the subatomic particle will cause it to move significantly, so although the position has been measured accurately, the velocity of the particle will have been altered. By learning the position, you have rendered any information you previously had on the velocity useless. In other words, the observer affects the observed.
Here also we see the size affects our perception. Our visible universe has a set of rules while at the sub-atomic level another set of rules is equally admissible! In human terms it may explain we all have our pubic persona that is dusted up version of our real selves. Dr. Jeckyll and Mr. Hyde is an extreme case.
No wonder we require an uncertainty principle to underpin our finite nature. We cannot say for certain which Party shall win the 2012 USA elections. History constantly points to this principle running through the events and men.
