Lothar Schafer at Science and Nonduality - Quantum

Finally, after watching this I've been able to piece together how classical physics and quantum can be understood together. I've been unable to understand free will until watching this which shows how we are not living in a determined world, that the previous state of our being doesn't always determine the future state. Much of our science up to Newton was based in the idea of hard causality, that the universe was some sort of grand rule obeying clockwork. But a lot of theoretical and experimental work by a great many people has shown clearly that in the realm of the very small, things are fundamentally uncertain, and essentially random within certain probability constraints.

For anyone completely stuck in the classical Newtonian understanding of physics who is unable to see how quantum works and is the greater underlying reality which allows a spiritual one too, this video might crack the door open for them, if they are willing to see the information as mental Gold and put it in their figurative pocket of the mind.

Divergence to spot size calculator: http://tinyurl.com/spotsize - 1 mRad is about .057 degrees which from the earth would expand to be ~10% the diameters of the moon or sun at their distances.

Divergence Calculator: http://www.pseudonomen.com/lasers/ca...alculator.html - Measure your lasers beamwidth at 1 foot & then at a further distance to calculate the divergence.
