Not Even Wrong - Woit

 

Science that is not scientific

As with most things related to quantum physics even the title of the book, “Not Even Wrong” by Peter Woit, is hard to understand.  When dealing with things that don’t behave intuitively, as is the case with quantum physics, and on the brink of human understanding, clarity is critical. Nevertheless, physicists always seem to revel in their own intellect and have little regard for those of us who don’t share their higher order IQs.  Woit seems different notwithstanding his choice of titles for this book.   The purpose of this book was to write down in one place the case against string theory and the monolithic institution of researchers and worshipers of the theory that grew up in the shadow, or on the coat tails, of Ed Witten.  Woit does this by giving us a short history of theoretical and experimental particle physics that begat quantum theory, the standard model, and with Ed Witten’s help, string theory.  This is all very clear and tracks very well, and of course necessary to understand the criticisms he later levies against string theory in general and the M-Theory that was to follow, more specifically.

First a word on understandability:  When I took second year physics in college -- electromagnetic theory --  and experienced imaginary numbers, flux, phases, and triple integrals for the first time I had to wonder if any of it was truly understood, or what was understood was how to manipulate the observed phenomenon for useful purposes.  Of course my professor spoke with a deep Czechoslovakian accent which made the lectures even harder to understand.  Day in and day out he would stand in front of the room with his back to the class and lecture to the chalk-board filling any available space with a flurry of equations.  One day he was absent and his wife took over the lecture for him.   In some strange confluence of synchronicity, his wife stood in front of the classroom, with her back to us, and in a deep Czechoslovakian accent lectured to the chalk-board filling every available space with a flurry of equations.  The class felt as if we had just experienced a breach in time-space and with perfect symmetry as the professors’ anti-matter component slipped into our room for the day.  This is difficult stuff.  It takes a great deal of study to understand the very simple let alone the highly complex.  In some cases, as Woit points out, even the experts get fooled due to lack of understanding or interest in taking the necessary time, and pain, to gain more than a general sense of the topic.  Decades later I understand all too well, that I will never truly understand what is being discussed in Woit’s book or any number of texts on the subject that I might open.   Nevertheless, I gave it a try and have come away with a few insights I feel are worth noting in my review.

First, Woit really only has a single point to make, albeit an extremely powerful point.  The fact is that after two full decades of research into string theory, not a single prediction coming out of the theory can be confirmed experimentally.   To me, a book isn’t necessary to convey this message.  His deeper message, and his second important point, is that a book was indeed necessary because after years of screaming into the abyss with no one is hearing his message too many resources have been and continue to be wasted in pursuit of a theory that ceases to be scientific.   Theory, no matter how beautiful it might be to the eye of the beholder is no more than mental masturbation without experimental results confirming something, anything, not, as has been the case with string theory, nothing, zip, zero, zilch, nada, butt-kiss.   So whereas I may not understand exactly how a 1-dimensional closed loop of energy vibrates across 10 or 11 dimensions of space and time, six or more of those dimensions are so small we can’t see them thus we don’t need to worry about them, I do understand that I shouldn’t believe you even though I can’t do the math myself.  Science ceases to be scientific when the hypothesis cannot be proven.  For this insight Woit is highly effective and should be thanked for trying to make this simple message clear.  Has his message been heard?  I heard him, I can only hope the next generation of quantum physicist hear him before investing a life-time in pursuit of a science that is not scientific.
