Why is quantum theory so strange? The weirdness could be in our heads

PARTICLES that also act like waves; the “spooky action at a distance” of entanglement;
those dead-and-alive cats. Small wonder people often trot out physicist Richard Feynman’s
line that “nobody understands quantum mechanics”. With quantum theory, we have
developed an exceedingly successful description of how fundamental reality works.
It also amounts to a full-frontal assault on our intuitions about how reality should work.
Or does it? “It only seems strange to us because our immediate everyday experience
of the world is so very limited,” says Sean Carroll at the California Institute of Technology.
#
There is a big difference between seeming strange and being strange, too.
“If quantum mechanics is right, it can’t truly be strange – it’s how nature works,” says Carroll.
#
We don’t know the extent to which it can or should apply to macroscopic objects.
#
“Whatever that underlying reality turns out to be, it is almost certainly ‘strange’
relative to our classical experience,”

''Invent formulas that we decide that the microcosm has to follow, and that later we verify that
they are strange and incomprehensible, but to say again that they are correct for the simple
fact that we have invented them and that if they seem strange it is because we are not capable
of understanding so wonderful formulas,
I find it dishonest on our part.
It has always been demanded that a formula or theory must be constantly checked to be true,
and if it is a probability theory, there must also be multiple measurements and proofs
that such a possibility is correct.
And that does not happen with quantum formulas, but quite the opposite.
They are demonstrated where particles are searched for and found, that is, in particle accelerators.
There the uncertainty principle and probabilities according to the wave function do not exist.
There, it is the quality and consistency of the measuring devices that measure us and find the particles.''

Agree. Every season a new quantum particle is discovered to explain the strangeness
of the previous and so until the next season, until a new cycle of discovery. /Israel /
