When atoms of Calcium are brought to a high energy state and are allowed to return to a lower energy state while in a fixed position, each atom emits two photons which fly off in opposite directions. If the spin of the photons is measured in the same axis (vertical, horizontal, front to back or any other axis) then the two photons have opposite direction spins (clockwise and anticlockwise). According to quantum theory, subatomic particles have latent spins in all axes but once the spin is measured along one axis, it is never a fractional one and after measurement along one axis, it is not possible to detect or measure the particle's spin direction along other axis. Many physicists have done this experiment and the spin of the particles measured at various distances. The farthest distance apart between the particles was eleven kilometers. Einstein could not accept that two particles separated in space could influence the behavior or properties of each other. This would have violated his theory of special relativity as one particle would be communicating with the other faster than the speed of light. He called it spooky action at a distance and remarked that god does not play dice. He claimed that the two particles were programmed at birth to have opposite spins.
John Bell got the Nobel prize in physics for thinking up an experiment carried out decades later when more sophisticated technology and instruments became available. These were the ability to measure the direction of spin of particles in the vertical, horizontal and front to back axis (or any other axis). In experiments where the spin direction was measured along the same axis at any angle from the vertical, horizontal or front to back, the experimenter always got opposite results for the two particles. Bell's theorem was simple. The spin direction can be either clockwise or anti-clockwise. If one assumes that the one sided photon is programmed, say clockwise for vertical, anti-clockwise for horizontal and clockwise for front to back, its program would be CAC. In that case the opposite side photon would have to be programmed ACA.
If the experiment was randomized so that two independent experimenters measured the photon spin in any one of the three directions, the results would be CA, CC, CA for vertical axis on one photon and vertical, horizontal and front to back axis on the second. The next set for horizontal axis on the first photon and vertical, horizontal and front to back on the second photon would be AA, AC, AA respectively. For front to back axis on the first photon and three in the same order on the second photon would be CA, CC, CA respectively. Of the nine results, you will notice that, four are the same (AA or CC) and five are different. Thus a series of random tests should give opposite results more than 50% of the time. Yet when repeated experiments are carried out the results always show an agreement of 50% but never greater. This proves that the two photons are not pre-programmed and do not have a fixed spin until measured, but if measured along the same axis they are always opposite. Once the spin on one particle is measured the second entangled particle takes on the opposite spin along the same axis.
This raises strange questions. Was the choice of switching off or on the detector in part one of my article pre-ordained? If so then there is no free will. If the particles are entangled at birth and yet free to choose their spin until measurement, what is reality? By the way despite our Indian habit of entangling all inventions to our scriptures and philosophy, quantum physics has nothing to do with the dance of Shiva, Buddhism or Taoism. If you still believe the opposite, you should nominate me for the Nobel Prize in physics, as I have found two large particles (human beings) entangled at a distance of 9000 miles. They are the president of the US (Bush or Obama) and Manmohan Singh. As soon as a mere thought passes through the president's mind, Manmohan Singh immediately and spontaneously does the same thing not the opposite.
One psychologist friend said to me My diagnosis is wrong and the above is not quantum entanglement. Maybe Manmohan Singh has no free will and he is a Zombie (Look up psychological definition of Zombie). Another friend who is a comedian said, maybe Manmohan Singh is playing the part of a ventriloquist's dummy. Simultaneously, all three of us said 'you have got to hand it to Sonia. She is like the nuclear strong force which increases with distance, unlike gravity, electromagnetism and the weak force, so she can throw her voice to large distances and alter it to sound like that of a man.
