Realism is the philosophical stance of most sane human beings, scientists included. An independent reality, it now appears, has become the latest casualty of quantum mechanics. The universe is nonlocal, nondeterministic, and apparently "unreal" as well.

The concepts introduced by both theories are disturbing to our classically trained minds and to our everyday experiences, but if anything, they hint that the universe remains comprehensible.

Predictions about the future of science and technology are notorious for turning out to be wrong. Nevertheless, we know of at least a few topics that will undoubtedly be active areas of research for the next half-century.

Einstein, who deposed Newton, grew intellectually stodgy in old age. With respect to quantum mechanics (QM), he was positively reactionary.

Cartesian dualism presupposed an independent reality "out there" that remains undisturbed during scientific observation. Heisenberg's uncertainty principle removes the partition separating mind from matter, rendering a fatal blow to Cartesian dualism.

For lack of a better explanation for the values of certain constants we end up conceding that something has to be a certain way, because it can't be otherwise if we are here to observe it.

Why is there something rather than nothing? What existed before the Big Bang? How can everything we know to exist in the entire observable universe ha...

There are at least two crucial circumstances in which we absolutely need a theory in which general relativity and quantum mechanics are compatible. One is the case of the objects we call black holes, and the second is the Big Bang.

In order to unify the theory of the large -- general relativity -- with the theory of the small -- quantum mechanics -- physicists had to examine the properties of spacetime on the tiniest scales. And here is where the problem arose.
