A microbe is not subject to gravitational pulls and pushes? When is an object subject to gravity?

Many people have accepted that perception is theory-laden yet this done not throw into question the central realist claim that reality is mind-independant and objects exist independant of the mind.

These two claims are not the same thing. Because perception is theory laden does not change the fact that a bear's shit stinks.

The Copenhagen theorists were not denying the *existence* of electrons only calling in to question the classical account of how electrons came to have position, momentum and other attributes. One of the best researchers on the philosophy of physics, Arthur Fine, argues for agnosticism:
"Quantum theory neither supports that realism of atoms and molecules etc.,to which the old positivism was opposed, nor does it deny it. Thus I will urge the forgotten moral of the new positivism; namel, that realism is a metaphysical doctrine that finds neither support nor refutation in scientific theories or investigations" Arthur Fine, *Is Scientific Realism Compatible With Quantum Physics?*, in The Shaky Game p169.

In the same book, Heisenberg also said:
"While political ideas may gain a convincing influence among great masses of people just because they correspond or seem to correspond to the precailing interests of the people, scientific ideas will spread only becuas they are true. There are objective and final criteria assuring the correctness of a scientific statement" p194
...which leads me to believe that the philosophical implications of the uncertainty principle are blown out of proportion. Especially by people seeking to infer grandiose ideas about the world from the UP.
