We are very small entities on a little planet you probably wouldn't be able to see from outside the solar system, but you'd see our Sun as a star. You and I, we can't be seen from just a few hundred feet into the sky. Get a handle on how miniscule we are; from there it's possible to relate to those sub-microscopic entities much smaller than us as we are relatively much smaller than the Sun, and see that we belong to a world we cannot see.
The behaviour of that 'hidden' world is alarming - sometimes it defies the laws of Physics to produce very weird effects, like non-locality (connected events that happen simultaneously regardless of distance in spacetime) and wave-particle duality (everything at the quantum level is simultaneously a wave and a particle).
There are certain features common to the quantum world that we're strangely familiar with, and we even take for granted some of their manifestations in our lives. The more we know about tangible links between the quantum world and our own, the better equipped we are to make the most of our experiences.
Quantumology intends to free the mind that it may more easily follow the spirit, and if you baulk at the word 'spirit' I'd remind that nobody knows what goes on inside a black hole, because there our laws of physics break down and we've no idea what happens then. By the same token, we could all be said to be our own Singularity.
Physics and metaphysics certainly share common ground, but finding it can be a task and a half. The science is already here. Quantumology is the bridge over the bits you might want to know about, even if you're not into physics, so that you can build strength and optimism into your existence using real, proven tools to do the best possible job.
