An Armchair Guide to Quantum Mechanics

What is Quantum Mechanics?

More than 100 years ago, the founding fathers were faced with a series of experimental results that confounded their understanding regarding the nature of reality. Einstein never forgave Nature for doing this to him. Heisenberg had to run away to an island to figure it out. Pauli ended up going to Jung for analysis.

Gradually, they came to a new understanding—Quantum Mechanics—but in the process, they had to throw away virtually all of the old physical picture of particles colliding and interacting like tiny billiard balls. Instead, we now have shifting probability waves existing in an implicate layer of reality and manifesting in explicate results. Our very language and concepts struggle to cope with expressing in words what is clear mathematically. Bohr had to invent a new form of double-think, complementarity, to try and ride the paradox: Nature expressing herself in both wave and particle forms, within the same experiment.

Why is it important?

Quantum mechanics, and the theories built from its foundations, is our fundamental theory of matter and forces. It underpins everything we understand about the nature of our universe. In the earliest moments of creation, fractions of a second into the Big Bang, quantum theory governed the structure and evolution of our young cosmos. Delicate measurements of the universal ‘heat map’ spread across the sky, reveal aspects of this quantum driven period.

Along with the awe-inspiring beauty and depth of the physics involved, quantum theory also has profound implications for our technology: from computer chips, MRI scans, communications and quantum computers.

Fundamentally, quantum mechanics is the most radical recasting of the nature of reality that we have ever experienced. The world is far stranger, and more supple, than we are led to believe.

Why should people have a basic understanding of QM?

It seems clear that the rigidly materialistic paradigm is crumbling, and we don’t yet know what is going to replace it.

We’re at a delicate time. On the one hand some of our political masters seek to undermine the expertise and results of the scientific community, replacing Truth with Story. On the other, enthusiastic and well-meaning groups working to assemble new paradigm thinking are promoting quantum ideas as a universal panacea for mind, body, spirit and anomalous experience.

Wider groups are trying to ride the turbulent waves and look for some understanding they can hold to. In order to steer between rigid scientism on one side and some of the flakier philosophies on the other, it helps to know a little of what quantum theory is really saying about the world.
