Science, Religion and Quantum Mechanics

The image above is mine - feel free to share...

It turns out that all the technology that is based on transistors - computers, mobile phones, the Internet, you name it - depends on the strange reality of quantum physics, as does almost everything that we see (and don't see) around us.

I recently read, or rather am having the great pleasure of working through in several passes, most of The Quantum Universe: Everything that Can Happen Does Happen, a book written by Professors Brian Cox and Jeff Forshaw. (I say “most of” because the the chapters in the book lead you up to a real worked example in the Appendix, a seriously high mountain which I have yet to attempt!)

In 1927 J.B.S. Haldane famously wrote: “I have no doubt that in reality the future will be vastly more surprising than anything I can imagine. Now my own suspicion is that the Universe is not only queerer than we suppose, but queerer than we can suppose.”

The Universe is truly a queer and wonderful place, and this book clearly explains some of its most queer and wonderful mechanisms. The method of explanation, using familiar clock faces and waves, doesn't eliminate the occasionally frightening mathematics, but conveys brilliantly what is really going on.

(Anyone thinking "I can't do maths", by the way, has never had teachers like these (or Salman Khan, see bottom of this post). I wish they had taught me when I first attempted to learn this stuff!)

Equally fascinating is the authors' explanation of how science reached its current understanding of the theory that predicts so accurately how the Universe behaves, from the chemistry of life (and table salt) to why (since atoms are mostly empty space) we don't fall through the floor, to the life-cycle of stars.

Unusually in a science book, the authors are not afraid to explain the limitations of science, either: scientific knowledge isn't perfect and fixed, but always growing, and here is a great description of how science helps knowledge to grow.

You can read a really good review of the book here. Click the images for more about the authors.

I find it sad that in today's world some religions still cannot accept science, but must imagine an alternative reality (with a bogus science that doesn't constantly test itself critically against evidence, as real science does) that doesn't conflict with their beliefs.

It is also ironic, as well as sad, that people following these religions promote their messages (and do much else) using technology that depends on the science that they don't believe in.

Creationists (or whatever they call themselves) have a perfect right to believe in whatever they want. However I find it horrifying to read about persistent attempts to have Creationism taught in classrooms, and teachers being intimidated for teaching real science.

Disrespect for science is no new thing, and not confined to reality-denying religions. The “mad scientist”, for example, has always been a popular feature of movies and TV shows (even in The Muppets, one of my all-time favourites!). Scientists have not always performed well, and have not always found it easy to communicate clearly with the non-scientific public (a hard but essential job when issues like climate change and health are at stake).

A while back, the UK woke up to the fact that its future prosperity depended on reversing this trend, and many popular science programmes (among other things) have resulted - from the BBC's Bang Goes The Theory to some extraordinarily illuminating programmes featuring Brian Cox.

J.B.S. Haldane, should he be observing from somewhere what is happening in physics today, might not change his suspicion (the inner workings of gravity, for instance, still have much to reveal to science) - but I am sure that he would be “watching developments with great interest”.
