Nonfiction Book Reviews

Okay, first off, I just wanted to say I have never read Stephen Hawking’s A Brief History of Time.  I have heard that A Brief History of Time is supposed to be the more technical book out of the two, whereas the The Universe in a Nutshell is geared towards people who are not first and foremost scientists.

It is for that reason that I don’t envision myself ever reading A Brief History of Time, since I hardly understood The Universe in a Nutshell.  Here is an example of a mind-bending point that Hawking makes in Universe:

Yang-Mills theory is an extension of Maxwell theory that describes interactions in two other forces called the weak and strong nuclear forces.  However, ground state fluctuations have a much more serious effect in a quantum theory of gravity.  Again, each wavelength would have a ground state energy.  Since there is no limit to how short the wavelengths of the Maxwell field can be, there are an infinite number of different wavelengths in any region of spacetime and an infinite amount of ground state energy.  Because energy density is, like matter, a source of gravity, this infinite energy density ought to mean there is enough gravitational attraction in the universe to curl spacetime into a single point, which obviously hasn’t happened.
~The Universe in a Nutshell, page 46.

Obviously.

I should confess: My last science class was in the 10th grade, where I took biology.  I’m not exactly a science expert.  But if I understand right, I’m just the type of person Hawking was trying to target with this book - someone interested in science and wanting to learn more about the deeper principles and ideas being explored, but who doesn’t have a PhD in anything, let alone theoretical physics.  (I didn’t realize until I started adding links to that sentence, how many book reviews I’ve written on here about books on science, as compared to books about art [Art books reviewed: 0.]  You can tell what I am really interested in.)

In Hawking’s defense, these ideas are extraordinarily complicated, and that’s not exactly his fault.  I can’t imagine a harder task than trying to explain quantum physics to your average Joe, and that’s what Hawking was attempting to do.

I do give him kudos for sprinkling humor throughout the book.  He talks about bets that he’s made with other scientists on obscure scientific theories, added lots of drawings with little green men in them, and then topped it all off with dry humor comments that added spice to the book.  Here’s an example:

It would be possible to detect the radiation from much smaller and hotter black holes, but there don’t seem to be many of them around.  That is a pity.  If one were discovered, I would get a Nobel Prize.
~The Universe in a Nutshell, page 120.

Oh shucks.  If only there were more black holes in our general vicinity.

I read on Amazon that some people were upset with how much Hawking “dumbed down” the science, and wrote scathing remarks that if you knew anything about science, you could just skip this book because nothing in it would be new.  Apparently, I know less than nothing about science (no surprise there).

In the end, I give The Universe in a Nutshell 4 stars out of 5.  If you’re really into this kind of thing, and have the patience to try to unravel some of the theories that Hawking presents, then by all means, enjoy.  There is a lot of information to digest here, if you have the grits and determination to do it.  I liked learning what I could from it, but I doubt I’ll pick it up again.
