Editorial Reviews

From Publishers Weekly

How a photon can be in two places at once is just one of the conundrums of quantum physics that Fayer (Elements of Quantum Mechanics) helps to unravel. The Stanford University Professor of Chemistry provides a roadmap for non-scientific readers who wish to understand the subject but lack advanced mathematical training. Fayer's belief that our everyday experiences "teach us to think in terms of classical physics" helps him easily breach the leap from playing ball to understanding how the earth orbits the sun. But because what we learn as children "prepares us to view nature in a manner that is fundamentally wrong," most people are at a loss when probing seemingly simple questions: "Why are cherries red and blueberries blue?" While the large objects treated in classical physics can be measured without appreciable disturbance, the same is not true at the quantum level. We may take the color and size of fruit for granted, but Fayer illustrates the ways in which "the natural world is driven by quantum phenomena" with a serious, accessible treatment of a complex and fascinating subject.

More About the Author

Profile of Michael D. Fayer
By Melissa Marino


In the air we breathe, the water we drink, and the glasses we may need to read these words, molecules are on the move. Even the hardest of materials abounds with shaking, vibrating, bouncing, and twisting at the molecular level. These motions, which are invisible to the unaided eye, give our world form and function, imparting the physical properties we detect with our everyday senses.
Using sophisticated ultrafast spectroscopic methods, Michael D. Fayer, the David Mulvane Ehrsam and Edward Curtis Franklin Professor of Chemistry at Stanford University, has been working out these invisible movements for more than a third of a century

Electric youth
A career in science seems somewhat inevitable growing up in a family like Fayer's. His father William, an electrical engineer at the dawn of the modern electronics era, exuded excitement for science and technology and easily imparted that fascination to his son.
"When I was very young, maybe 6 or 7, my father came home one day, and he held up this little thing in his hand and said, 'This is a transistor. Soon there will be no more vacuum tubes!' This is how I grew up."
His father was correct. Soon vacuum tubes, the hot, bulky components that powered early electronics, were obsolete, replaced with the tiny transistor that led the way to the downsized electronics of today. Always at the forefront of technology, William Fayer not only made science and electronics his career, but his hobby. With an electronics laboratory in the basement, there were always electronic "toys" - oscilloscopes, signal generators, and soldering irons - with which a young boy could experiment.
Later, electronics gave way to pyrotechnics and photography - hobbies that introduced Fayer to the fascinating world of chemistry.
"With chemistry, you can make all sorts of nifty things, like fireworks," says Fayer. And the "complicated chemical process" of photography became one of Fayer's extracurricular passions.
Science was ingrained in him, and Fayer anticipated a career in science from a very young age.
"It sounds crazy, but when I was very young, 8 or 10 years old, I thought I was going to grow up and become a physics professor."
This youthful certainty quickly changed though upon entering college at the University of California at Berkeley. Although his plan was to major in physics, a summer research program led him to work with a chemist.
"It turned out that the types of initial equipment that needed to built used radiofrequency electronics," Fayer says. Through his father, the electronics instrumentation in the house and the lab, and his experience as an amateur radio operator in junior high school and high school, Fayer knew how to build electronic equipment. "So, as a sophomore, I helped build up a new lab."
Fayer continued research throughout his undergraduate years and later as a graduate student studying physical chemistry.
"Physical chemistry is the physics of molecules. When you look at the world around you, everything is controlled by processes that happen at a 1 nanometer length scale - the size of molecules. The chemical reactions and processes that cause disease and make life, all of this is chemistry. The things that affect you in your day to day life are all chemistry."

Seeing the light
After finishing his doctorate at Berkeley in 1974, Fayer was offered a faculty position at Stanford University at the age of 26 - even then, a rare event without the now requisite "postdoc." At Stanford, he began the eclectic mix of experiments that has run the gamut from water, flames, and diamonds to proteins and artificial cell membranes.
"My interests are in trying to understand at a molecular level how complicated systems of molecules evolve in time and how intermolecular interactions - how molecules 'feel' each other and move relative to each other - give systems their properties."
To study these nanoscopic processes takes some sophisticated instrumentation. As a graduate student, Fayer had been working with magnetic resonance, which used pulses of microwave energy to detect and measure the dynamics of "spins" of electrons in a material. These types of techniques form the basis of modern magnetic resonance imaging (MRI).
In the early 1970s, Fayer had read a papers by about a technique called the Photon Echo that used optical - visible and ultraviolet (UV) light - pulses instead of the radio frequency pulses employed in magnetic resonance. This sparked Fayer's interest and, as an independent investigator, he began branching out and experimenting with these new techniques.
Although inspired by the early photon echo experiments, he found that this potentially useful technique wasn't amenable to measuring the ultrafast dynamics of molecules that interested him. So Fayer expanded the techniques using tunable picosecond lasers (ultrafast at the time) to be able to use the right color of light for the molecules of interest and to make the measurements fast enough to study molecular dynamics in condensed matter materials. He also began apply other nonlinear optical pulse sequences to the study of dynamics of molecular processes.
One of the methods that Fayer's group began developing for application to a wide variety of chemical and materials problems is the transient grating technique, now one of the most widely used nonlinear optical techniques in chemistry. In a transient grating experiment, two ultrafast pulses of light make a hologram in the sample. A delayed third light pulse is used to read out the time evolution of the hologram. Transient grating experiments were used to measure diverse phenomena, such as the mechanical properties of membranes, heat transport in materials, electronic excited state dynamics, the rotation of molecules in liquids and liquid crystals, and the velocity of atoms in flames. The technique is "nonlinear" because one shoots three pulses of laser light into a sample at different times, and the sample generates a fourth pulse of light, the signal, which carries the information about molecular processes and properties.
Fayer used transient gratings and a variety of other methods and theory to study electronic excitation transport - a process where light energy absorbed by one molecules jumps to another. The most famous example of this is the excitation transfer that happens between chlorophyll molecules in the initial stage of photosynthesis. For example, Fayer's group used excitation transfer in polymers to study their structure.
One of the projects he is most proud of was the group's work on low temperature glasses. "Glasses show up all over the place," Fayer explains. Unlike crystalline solids, glasses - like window glass, plastics, and other organic solids - have no regular pattern in the way the molecules arrange themselves. "They're like a liquid that is solid. And even if you go to very low temperatures (a few degrees Kelvin), the molecules can still rearrange themselves."
"There was a tremendous interest in understanding the dynamics of glasses because they're disordered." Previous research using a slow optical technique called "hole burning" missed the essence of the problem, that is, that glass dynamics occur on all time scales, from extremely fast (picoseconds) to very slow (thousands of seconds and longer). Using a variety of optical techniques  photon echoes, stimulated photon echoes, fast to slow time dependent hole burning experiments  Fayer's group was able to detail the molecular dynamics of glasses over a wide range of timescales, from picoseconds to 10,000 seconds.
They proved theoretically that all of these experiments and a variety of other optical techniques are equivalent, but operate on different time scales, "We showed the relationship between these slow, fast and medium time scale experiments. There wasn't one single experiment that was going to provide all of the important information."

Infrared shift
Although he had much success with these ultrafast nonlinear optical experiments, visible and UV light were not ideal for some of the other problems Fayer wanted to address.
"In the 1990s, we started thinking about...using infrared (IR) pulses to do similar nonlinear experiments on the vibrations of molecules," Fayer recalls.
When an infrared pulse hits a molecule, the bonds between the atoms vibrate, and Fayer's next step was to measure these "vibrational echoes," similar to spin echoes measured by NMR and photon echoes measured by optical techniques. But again, the available techniques had to be tweaked.
Fayer notes his good fortune in being at Stanford, whose physics department had invented the Free Electron Laser (FEL), a giant linear accelerator the size of two football fields the provided input for a type of laser that could produce short light pulses. The physicists were trying to develop a FEL to work in the infrared - a project in line with Fayer's interests.
"I became the developer with them of applying FELs to look at molecular systems with ultrafast IR pulses," Fayer says. In 1993, Fayer's group performed the first "vibrational echo" experiments on molecules in liquid and glass.
Following these early one dimensional experiments, the Fayer group now uses two dimensional infrared (2D-IR) vibrational echo spectroscopy, akin to 2D NMR, to captured under thermal equilibrium conditions the exceptionally rapid formation and dissolution of solute-solvent complexes and molecular isomerization - reactions too fast to be measured by other methods.
One of Fayer's key targets with the infrared techniques has been water. A deceptively simple molecule, water is nature's most important solvent.
"Water as a solvent makes a tremendous number of chemical processes possible. It enables charges to move, electron transfer, proton transfer...its ability to facilitate chemical and biological processes depends on water's ability to rearrange its structure," says Fayer. Fayer's group used 2D-IR vibrational echo spectroscopy to obtained a detailed picture of the very fast (femtosecond to picosecond) motions of water molecules in bulk water.
In nature and in technological applications like fuel cells, water is often confined to very small, tight niches. Fayer's group has done experiments on as few as 40 water molecules and has found that the properties of such nanoconfined water are wildly different from those of bulk water in the ocean or in a drinking glass.
Fayer used infrared spectroscopy to study water in reverse micelles - tiny artificial "bubbles" that can encase miniscule amounts of water. In these tiny pools of water, containing only a few hundred molecules of water, "the motions of the water molecules are very different from bulk water," notes Fayer.
One application in which confined water plays an important role is in modern fuel cells. Recently, Fayer made the first measurements of the behavior of water inside a fuel cell membrane. Understanding such dynamics could be crucial to developing hydrogen fuel cells as an alternative fuel source to power our automobiles.
Fayer probed another interesting aspect of water's behavior - how it behaves in a highly concentrated salt solution.
"There had been claims that in these highly concentrated salt solutions, the ability of water molecules to change their orientation, to restructure, slowed down by a factor of 30 to 50," Fayer says. But using 2D-IR vibrational echo experiments, Fayer has found that even in an extremely concentrated salt solutions, the slowing of the dynamics was about a factor of 3.
"It really shows that water, even in the presence of charges, can still restructure, can change its geometry really rapidly, which is really important for processes like proton transfer and protein folding"
Fayer is continuing to probe the mysteries of nature's favorite solvent, with his most recent experiments comparing the effects and interactions of confinement and charged interfaces.
With no shortage of molecules to study and experiments to run, Fayer still conveys the youthful enthusiasm for science that he acquired from his father and his early mentors. Now in his 38th year at Stanford, retirement, he says, is not an option.
"I've been here over a third of a century - and you know you're getting old when you measure things in fractions of centuries," he quips. "I hope to hold some record for being at Stanford longer than anybody."
Echoes of the young tinkerer continue to resound - in his work and in his hobbies. Fayer has kept up with his lifelong passion for photography - which, although once a chemistry experiment itself, has now evolved into the digital age. In place of chemical baths and film, Fayer's photography tools now include a digital camera and photo-editing software.
Like photography, science continues to change, with Fayer adjusting course along with it. He wouldn't have it any other way.
"Science is never boring. It can be frustrating and difficult and trying, but it's never boring. I don't know how to be bored."

People are always talking about quantum leaps and quantum this and that, with the unspoken understanding that an ordinary person will never really understand what a quantum is. And why would you even want to?

In this terrific book, Michael Fayer explains how the world around us cannot be understood without quantum mechanics, and he makes quantum mechanics understandable using the concept of "Absolutely Small". Size matters. A blade of grass is large to an ant and tiny to a cat, but the particles that make up our world, especially electrons, are not large compared to anything. They are "Absolutely Small". For this reason, there is no tool that can be used to study an electron without pushing it around so you never know quite where it is.

After teaching quantum theory in an totally smashing nonmathematical manner, Fayer uses it to explain why cherries are red and blueberries are blue, why molecules exist and each has its own characteristic shape, the difference between beer and soap (both have foam), why carbon dioxide is a greenhouse gas, the difference between a metal and an insulator, and my favorite, what is the up with trans fats, saturated fats, and cholesterol, why your doctor is constantly checking your HDL and LDL, and why food processors "partially hydrogenate" the fats in oils and then try to cover it up. You will never buy cooking oil in the supermarket again without carefully reading the label.

There is a little bit of math, mostly multiplication, and quite a few diagrams to study, but this book can qualify as beach reading for the intellectually curious. If you took chemistry in school but can't remember anything, this book is totally for you!

While I personally agree with the enthusiastic praise of most other reviewers, I think they oversell this book. It's not a Six Easy Pieces, ABC of Relativity or Thirty Years that Shook Physics. It has a narrower and deeper goal, and is likely to appeal to a smaller group. People with small aptitude for physics and mathematics, or little training and experience in them, will not find the explanations useful. People with extensive knowledge will find them too superficial. The ideal reader mastered Newtonian mechanics in high school, but didn't pursue physics in college.

The book is non-mathematical, but it uses rigorous and systematic reasoning that few math-phobes will tolerate. There is no physical intuition, in fact the author repeatedly warns against using it. That is a benefit to people who want to deepen their understanding, but it makes the argument abstract, requiring close attention. You need a pen and paper with you when you read this book, and you will be constantly turning back to refer to prior pages. It teaches you how to think about setting up quantum mechanical problems and then gives you the answer. That does save you a lot of detailed math (most of which has to be done on computer anyway) but it requires a significant fraction of the effort of learning the full subject.

Another difficulty of this approach is you have to accept a lot of principles that seem as arbitrary as epicycles. Why only two electrons per orbital?

Do we need yet another popular book on quantum mechanics? The answer seems to be eternally yes, although I must confess to being a little tired of reading about black holes, wormholes, and all manner of exotica. This by contrast is a remarkably level-headed introduction to basic quantum mechanics and real-life phenomena here on Planet Earth. I enjoyed the fun treatment of chemical bonding, aromatic molecules, and solids.

Putting on a critic's hat, I might have preferred a few pages on somewhat more advanced chemistry, e.g. heme and not just benzene as an example of an aromatic molecule. But that's just my personal prejudice - I am a chemist and this book is meant for a popular audience. A couple of minor typos were more funny than annoying, e.g. repeated mention of "acidic acid" (for acetic acid).

In the preface to this book the author begins: "If you are reading this book, you probably fall into one of two broad categories of people. You may be one of my colleagues who is steeped in the mysteries of quantum theory and wants to see how someone writes a serious book on quantum theory with no math. Or, you may be one of the vast majority of people who look at the world around them without a clear view of why many things in everyday life are the way they are." As the holder of a Ph. D. in theoretical chemistry, I definitely belong to the first group. (Aside: this is not really a book on "quantum theory" as the physicists might consider it, but strongly emphasizes the chemical applications of quantum theory, so "quantum chemistry" or "theoretical chemistry" would be more accurate than "quantum theory" in the second sentence of this quote. But this makes it even more clear that I belong to that first group.) "With no math" is not quite true; there is certainly a bit of mathematics in his treatment. But it is definitely a book intended for people with only a small mathematical background, and I think this book probably succeeds at its task. I have to put in a caveat in that the material he covers is _so_ familiar to me that it is hard to put myself in a layman's position to determine how clearly he explains things. I think he does a fairly good job, thus four stars. I'm not sure it is good enough to qualify for five, but I would not argue strongly that it does not deserve the fifth star.

The author clearly embraces the "Copenhagen interpretation" of quantum mechanics. I, myself, do not: for me quantum mechanics is a theory (the only theory we have at present that really works) that explains what we will observe, in an accurately quantitative manner.
