I’m reading from a copy of the New Scientist (journal) promotional email:

Quantum physics has always been a source of mystery and delight. It defies common sense yet we have learned to manipulate these strange phenomena.

Hey, is this even the right question? I think we should be saying that “common sense” defies physics. “Common sense” says that the mind is in the brain; aspirin kills pain; cancer is a consequence of genes; old age is a “disease” of wearing out parts; good whole food cannot hurt you; gravity is a hidden force that controls the universe; and vaccinations help prevent disease.

None of these supposed common sense observations are necessarily true.

Quantum physics says something far more enriching and exciting than common sense. It says the “real” world is an illusion. It’s all built with smoke and mirrors, on a platform of mere probability. Things only appear solid and real; they are not. There is no matter (particles), only the probability of particles. Electrons, one of the fundamental building blocks of the universe; are particles—but not really—they are actually waves… or both… or neither. Just a smudge or a whisper, really.

Hang on to your hat. Common sense cannot take you on this wild roller coaster ride.

I am constantly amused by the words of celebrity physicist Michio Kaku, who says, “It is often stated that of all the theories proposed in this century, the silliest is quantum theory. Some say that the only thing that quantum theory has going for it, in fact, is that it is unquestionably correct.” Boom boom! Continue reading →
