Read full description of the books:
Physics is a complex, even daunting topic, but it is also deeply satisfying--even thrilling. And liberated from its mathematical underpinnings, physics suddenly becomes accessible to anyone with the curiosity and imagination to explore its beauty. Science without math? It's not that unusual. For example, we can understand the concept of gravity without solving a single equation. So for all those who may have pondered what makes blueberries blue and strawberries red; for those who have wondered if sound really travels in waves; and why light behaves so differently from any other phenomenon in the universe, it's all a matter of quantum physics. Absolutely Small presents (and demystifies) the world of quantum science like no book before. It explores scientific concepts--from particles of light, to probability, to states of matter, to what makes greenhouse gases bad--in considerable depth, but using examples from the everyday world. Challenging without being intimidating, accessible but not condescending, Absolutely Small develops the reader's intuition for the very nature of things at their most basic and intriguing levels.

Read information about the authorMichael D. Fayer is an American chemical physicist. He is the David Mulvane Ehrsam and Edward Curtis Franklin Professor of Chemistry at Stanford University.
He attended the University of California at Berkeley for both undergraduate and graduate school. He received his Ph.D. in Chemistry in 1974 under the supervision of Professor Charles B. Harris. Fayer began his academic career at Stanford as an Assistant Professor in 1974.
Fayer pioneered and launched a fundamental transformation of how the dynamics and dynamical interactions of complex molecular systems are investigated. The multiple experimental approaches he initiated have forever changed the manner in which chemists, biologist, molecular physicists, and materials scientist interrogate key aspects of nature.
By the early 1970s, just as Fayer was beginning his career, advances in laser technology were occurring to make pulses of light that were short enough to get to the time scales of molecular motions. While Fayer contributed to laser development, his real ground breaking contributions are in the methods that we use to look at molecular motions. Even with ultrashort pulses of light, it is still not possible to look, in the normal sense of the word, at molecules moving. Fayer developed and continues to develop and apply what are called ultrafast nonlinear optical experiments to the study of molecular dynamics in complex molecular systems such as liquids, glasses, crystals, and biological systems. Ultrafast nonlinear methods involve sequences of light pulses. In a typical experiment, three pulses of light impinge on a sample, and remarkably, the nonlinear interactions in the sample give rise to a fourth pulse of light that leaves the sample in a unique direction. If the experiments are conducted with visible light, you can actually see this nonlinear production of an additional light pulse. Three beams of ultrashort light pulses go into the sample, but four beams of light come out of the sample. It is this fourth beam of light that contains the information about the sample. There are many versions of this type of experiment that Fayer developed and applied to understanding molecular materials. Depending on the timing of the pulses, the colors of the pulses, and the directions of the pulses coming into the sample, different properties can be investigated. Fayer drove the field of ultrafast optical spectroscopy through his developments and use of these new methods to explicate the properties of complex molecular systems.
Fayer’s contributions are a play with two acts. In the first act, approximately 1974 through 1993, Fayer’s ultrafast nonlinear experiments were conducted using visible or ultraviolet light. These were the colors that were available with the laser technology of the time. In the early 1990s, Fayer realized that a great leap could be taken if the experiments could be extended to the infrared regions of the optical spectrum. Infrared light acts on molecular vibrations, which are the motions of the atoms that make up molecules. By using infrared light, it is possible to more directly interrogate the structural dynamics of molecular systems than with the use of visible or ultraviolet light. However, a source of ultrashort infrared light pulses was necessary, so Fayer got together with Stanford physicists to use a physics experiment, the free electron laser, and turn it to the study of molecular process using ultrafast infrared nonlinear experiments. These first experiments using the free electron laser, which was two football fields long and took a crew to run, set off an explosion of interest in infrared nonlinear methods. In less than ten years, it became possible to perform the experiments using lasers that could be housed in a normal laboratory and did not require a free electron laser. Fayer contributed substantially to the equipment side, but his main creative impact was exploiting the new ultrafast infrared methods and technology for a wide variety
