The "if a tree falls in a forest with no one to hear it" analogy that opens the article is quite on-point. Since sound is a human concept that only happens in our brains (or other brains that might act the same way), a tree most definitely does not make a sound unless someone is there to hear it. (It makes silent air pressure waves.) In the same way, any "objective" reality that underlies quantum physics is not really perceptible by the human organism. We cannot perceive the behavior of individual electrons or other subatomic particles without measuring tools and, as Niels Bohr showed, those tools are only "showing" what they measure. They aren't showing the full, underlying reality.
