Quantum mechanics is a weird thing. Something like the last frontier of Science, it poses extreme questions which make us wonder about fundamental issues – like the role of measurement in what we see happening.
It goes to the hear of the biggest problems of existence – i.e. what is a particle, what is mass et cetera. But there is a slight problem: consensus in the interpretation of quantum mechanics results is far beyond the horizon…
And the weird thing is that no one actually understands quantum theory. The quote popularly attributed to physicist Richard Feynman is probably apocryphal, but still true: if you think you understand quantum mechanics, then you don’t. That point was proved by a poll among 33 leading thinkers at a conference in Austria in 2011. This group of physicists, mathematicians and philosophers was given 16 multiple-choice questions about the meaning of the theory, and their answers displayed little consensus. 
But really most of the problems – according to my humble opinion – are based on our inability to overcome hunderds of years of dogmatism regarding specific issues. For example not all physicists can accept that human consciousness plays a role in the wave function collapse, simply because they do not believe in… consciousness!
Are we ready to question our “truths” in order to reach the… “truth” ?
