Quantum Physics.

 

Though Physics is going through exciting times in recent years, the ideas which are of most of interest to the emerging paradigms were born almost a hundred years ago and are generally refferred to as Quantum Mechanics or Quantum Physics.

 

Through pioneering work on the subatomic nature of reality by physicists such as Max Planck, Werner Heisenberg, Niels Bohr and Erwin Schrödinger, a fundamental shift in the models we use to describe reality took place, providing clear break with the dominant physics of the time, Classical Physics, as developed by Isaac Newton and others.

 

Whilst the laws of Classical Physics hold true for large scale objects, when we peer into the sub-atomic realm, looking at the stuff out of which the stuff of our universe appears to be made up of, many extraordinary things seem to happen and fundamental assumptions about the world we live can be questioned.

 

Among the most extraordinary observations or deductions of Quantum Mechanics are the following:

 

  • Particle - Wave duality
  • In QM Photons and electrons are held to have the properties of a particle and a wave at the same time, and that the properties they exhibit depend on the experimental parameters .

This gives us the beginnings of a remodelling of reality in terms not of distinct objects bouncing off each other in empty space, but of a web of interacting wave effects all to some degree enmeshed with each other .

Recent experiments have started to demonstate this duality at the atomic and molecular scale.

The Material Universe has ambiguous status between Particle nature and Wave nature.

 

  • Observation and the Collapse of the Probability Wave.
  • The mathematics of QM proposes that things have a probability to be somewhere and with some properties eg momentum, however , they become observable as things only by the process of observing them, ie that the probability that they are anywhere at anytime is collapsed by the intention to observe them somewhere at sometime. The act of observation, or measurement, has a determinant effect on that which we are wishing to observe.

Human conciousness is not fully seperated from Material Universe.

 

 

  • Quantum Entanglement

 

  • In the Quantum Physics world, when two or more particles are bought together or generated together their quantum states may become entangled such that physical states can not be given for each individual particle but instead given for the pair, or whole group. So what happens is that when an effect is made on one particle, the other particles instantly change their states in response to the effect ( eg observation) even though they are distant from the experiment: the information passes instantly to the entangled particles.

This becomes revolutionary when the the particles are seperated by large distances, theoretically, immense distances, and the instant transfer of information violates the principle that nothing can travel faster than the speed of light.,,,making Einstein famously unhappy.

There is an unkown connectivity between entanged particles which proposes instant connectivity across the univers and also brings up the possibility of some degree of entanglement linking all the particles in existence due to their original generation together in the process known as the Big Bang, which is the current model for explaining the beginnings of the universe.

 

 

 

 

 

Watch this entertaining introduction to Quantum Physics to see how revolutionary it is, and how extraordinarily succesfull!: The most succesfull set of equations yet in the history of Physics, despite predictions which go against common sennse and our normal understanding of what constitues Reality .

 

 

 

It is always worth remembering that whilst we talk of particles and atoms as things, they are infact very far from solid.

 

The Atom is generally considered to be 99.9999999% 'empty' space, an electromagnetically -ve charged electron cloud around a tiny tiny nucleus, containing neutrons and protons, in the center. If the nucleus was the size of a marble, it is estimated the electron particle would be a speck of dust half a mile away!

 

You, I, everything else in the Universe, are not made, even scientfically, by matter, but by space, a kind of field, holding together a coherent matrix of tiny specks called nuclei.

 

It has been estimated that when we remove all the space in humanity, all 7 Billion plus human beings on the planet would occupy the same volume as a sugar cube!

 

This Science is so radical and evolutionary that mostly it is ignored.

 

If we move further in to examine whats in the nucleus, we find Neutrons and Protons, which in turn appear to be made of subatomic particles named Quarks, of which there are several types with varying qualities such as Charge and Spin. But , Scientists don't actually know what they are. They don't have Mass and they don't seem to have space..they have Effect, they are known by their agreement with Mathematical equations and by the effects of their presence...really, 'Matter' breaks down not into component parts but into observations made by mind....'Matter' quite simply isn't there.

 

Its all 'straightforward' science, but if thought about for only a short while, it has extraordinarily revolutionary conclusions.
