What is so funny about Quantum Mechanics?

Over the last 29 years of APOGEE, the technical Festival of BITS Pilani, the campus has been thronged by eminent educationalists, technocrats, and visionaries from all over the Scientific Society. With the Pre-Apogee extravaganza sprinting splendidly along the second semester, it is but evident that this 30th edition would be no different.

16th of January, 2012 saw the presence of a well know professor of Physics, Prof. David Griffiths the recipient of the 1997 Robert A. Millikan award reserved for "those who have made outstanding scholarly contributions to physics education". Students here at BITS Pilani know him as the Author of "Introduction to Electrodynamics", the textbook for Physics 2. He has also written two more books on Quantum Mechanics and Elementary Particles.

His Talk, titled the same as this post, was centred on the abnormalities of Quantum Mechanics. He also focused on the paradoxes that arise due to the Realist, Copenhagen (or the orthodox) and the Agnostic views on Quantum Mechanics. For example, he talked about the fundamental application of Quantum Mechanics on the particle moving in one dimension, a concept familiar to all the engineering and science undergrads.

Now the question therein is that having determined the probabilistic position of the particle at any instant, where was the particle just before the measurement was made? He pointed out interesting analogies. The Realist would say it was "at the same position", the orthodox would say "It wasn't really anywhere, the act of measurement forced it to take a stand", while the agonist view would discard the question claiming "it is metaphysical"! "No two People in the world hold the same opinion on Quantum Mechanics", he said.

His talk also hovered onto the EPR Paradox of 1935 and the concept of Non-Locality (which was referred to as "spooky
