About the Author scottbembenek.com Scott Damian Bembenek grew up in the small town of Delavan, Wisconsin (population of approximately 5,000 at that time). Scott’s passion for science began around the age of five. Throughout his childhood, “science” took on a variety of forms, involving such things as batteries, circuits, magnets, anything electronic, insects, frogs, toads, salamanders, turtles, fish, etc. He conducted new “experiments” on a weekly (sometimes daily) basis, much to the astonishment of his (exceptionally patient) mother. Scott attended Carroll College (now Carroll University) in Waukesha, Wisconsin. There he further pursued his interest in chemistry, especially organic chemistry. However, by the end of his third year it was clear that his real interest was physical chemistry, a more theoretical, less laboratory-intensive version of chemistry. Indeed, Scott’s skills weren’t in the laboratory, which should have been clear to him much sooner since the laboratory potion of classes always brought down his grade – unlike for his fellow students. During this time his interest in physics grew. In his last year in college, Scott was fortunate to be able to take graduate-level classes and conduct research in physics under the direction of his advisor, as part of a self-designed curriculum toward a BS in chemistry and physics, which he received in 1993. Scott did his graduate work at the University of Kansas in Lawrence, where he investigated the dynamics of complex liquid systems using computer simulations and theoretical techniques. His work on supercooled liquids and glasses remains well cited even today. Scott received his PhD with honors in 1997 in theoretical chemical physics. Thereafter, he was awarded a National Research Council Fellowship and joined the Army Research Laboratory in Aberdeen, MD. There he used computational and theoretical techniques to study the dynamics of explosives. Scott pioneered a new approach to parameterizing interaction potentials necessary for accurate computer simulations. His work was well recognized, and upon the completion of his fellowship, he was immediately offered a full-time position. However, Scott had other plans. Intent on pursuing a career in academia, Scott took a research associate position (and a 50% salary cut) at Colorado State University. While computer simulations once again played a role in his work, the majority of his time at the office involved “old-school, paper and pencil” theoretical physics on fluid systems. In fact, his paper A Kinetic Theory for Dilute Dipolar Systems required more than 300 pages of derivations! When his term at Colorado State was finishing up after two years, he began looking for permanent employment. He attended a recruiting session at the university held by Johnson & Johnson that gave an overview of the drug discovery research at its San Diego site and potential employment opportunities. Although scheduled for an interview the following day, he had intended to pass on the opportunity. Some wise advice from a friend convinced him otherwise. Currently, he is a Principal Scientist in the Computer-Aided Drug Discovery group at Johnson & Johnson Pharmaceutical Research & Development in San Diego, CA, where he has worked since 2002. During his time there, he has made substantial contributions to numerous drug discovery projects and has worked in a variety of disease areas.

A brief conversation with a friend had started me down this long, often wayward, journey of writing my first popular science book, or, as I like to call it, a “science story.” My friend had recounted to me something they had read by a popular science writer. I was intrigued – not so much by the story itself (honestly, I have forgotten both the writer and the story), but rather by my friend’s excitement with what they had read. Let’s face it: science doesn’t often incite this response in the majority of people. So, as a scientist myself, it was uniquely rewarding for me to witness that enlightened moment my friend had experienced; I wanted to create those types of insightful science moments for others. Moreover, there’s a long, rich history of pivotal scientific achievements that have been clouded or simply ignored by the current popular science literature, and I wanted to bring these to light as well. It was these reflections that motivated me to write a popular science book. Thus began a journey that started in August of 2009. I was originally convinced that I could finish this project in two years. However, in the ensuing two years many things happened: I suffered paralysis in my left hand in a martial arts training accident but continued to write, before surgery and during the almost two-year recovery process, albeit a bit at a slower pace; got married and had four ceremonies (two in San Diego, one in Wisconsin, and one in China); took on more responsibility at work (I still have my day job); lost my mom; and became a dad. While all these things undoubtedly contributed to the extended time frame, they’re not the main reasons. I had a particular vision for the book, and I refused to publish it until it was realized. This, in addition to my bit of OCD and touch of perfectionism, resulted in a much-extended timeline. Nonetheless, I think (and I hope you do too) it was worth it. As I see it, a major stumbling block for the popularity of science is its presentation. It’s often presented in a very dry, dull manner. Many of you have taken those classes, seen those videos, heard those talks … and so have I. Clearly, for me (and other scientists) those things weren’t major setbacks – we became scientists, after all. Sure, we found some of those things boring, too (yes, scientists are human beings), while other parts of it we found quite exciting. For me the bottom line is this: science is a passion. My passion for science began when I was very young, around five years old. Back then “science” was about taking apart electronics and performing experiments – all humane! – on insects and garden-variety suburban amphibians. In fact, I will never forget when in second grade I went to our (very small) school library to check out a book on how electricity worked. In a quite discouraging tone the librarian said, “Wouldn’t you much rather check out a book with a nice story?” To which I replied, “Nope.” For most of my childhood I suffered from pretty bad allergies and asthma, which meant I missed a lot of school. The routine that was set up early in my academic life was this: I stayed home from school, Mom picked up my homework from my teachers, and I worked on it at home – sort of a power version of home schooling, if you will. And I always worked ahead when it came to my science and math classes. I guess you can say that science kept me engaged in school viii during those rather difficult years, providing me with a perspective that persisted into adulthood and has remained with me ever since. You see, I’ve been a scientist for a long time now, officially since 1997 when I got my PhD in theoretical chemical physics. Like I said, I became a scientist because I have a passion for it.

  • Physics Celebrity #24 (Neil's Bohr)
    Niels Bohr (Danish) 1885 – 1962) made foundational contributions to understanding atomic structure and quantum mechanics, for which he received Neils Bohr (1885 - 1962) the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research. He developed the Bohr model of the atom with the atomic nucleus at the centre and electrons in orbit around it, which he compared to the planets orbiting the Sun. He helped develop quantum mechanics, in which electrons move from one energy level to another in discrete steps, instead of continuously. He founded the Institute of Theoretical Physics at the University of Copenhagen, now known as the Niels Bohr Institute, which opened in 1920. Bohr mentored and collaborated with physicists including Hans Kramers, Oskar Klein, George de Hevesy and Werner Heisenberg. He predicted the existence of a new zirconium-like element, which was named hafnium, after Copenhagen, when it was discovered. Later, the element bohrium was named after him. He conceived the principle of complementarity: that items could be separately analysed as having contradictory properties, like behaving as a wave or a stream of particles. The notion of complementarity dominated his thinking on both science and philosophy. During the 1930s, Bohr gave refugees from Nazism temporary jobs at the Institute, provided them with financial support, arranged for them to be awarded fellowships from the Rockefeller Foundation, and ultimately found them places at various institutions around the world. After Denmark was occupied by the Germans, he had a dramatic meeting in Copenhagen with Heisenberg, who had become the head of the German nuclear energy project.

Schrodinger 2 Heisenberg 6 EINSTEIN 15 MAX PLANCK 25 Niels Bohr 31 Wolfgang Pauli 41 Paul Dirac 47 Roger Penrose 58 Stephen Hawking 68 Schrodinger Schrodinger is probably the most important scientist for our Scientific Spiritualism discussed in The Blink of An I and in Saltafide..Schrödinger coined the term Verschränkung (entanglement). More importantly Schrodinger discovered the universal connection of consciousness. It is important to note that John A. Ciampa discovered Schrodinger’s connected consciousness long after writing about it on his own. At the close of his book, What Is Life? (discussed below) Schrodinger reasons that consciousness is only a manifestation of a unitary consciousness pervading the universe. He mentions tat tvam asi, stating "you can throw yourself flat on the ground, stretched out upon Mother Earth, with the certain conviction that you are one with her and she with you”.[25]. Schrödinger concludes this chapter and the book with philosophical speculations on determinism, free will, and the mystery of human consciousness. He attempts to "see whether we cannot draw the correct non-contradictory conclusion from the following two premises: (1) My body functions as a pure mechanism according to Laws of Nature; and (2) Yet I know, by incontrovertible direct experience, that I am directing its motions, of which I foresee the effects, that may be fateful and all-important, in which case I feel and take full responsibility for them.

  • Case Study 6 Quantisation and Quanta After 1905
    Case Study 6 Quantisation and Quanta after 1905 1 Case Study 6 Quantisation and Quanta after 1905 In Case Study 6,we took the story of quantisation and quanta up to the publication of Einstein’s great paper of 1905. To recapitulate the story so far: • Planck derived the Planck formula for black-body radiation in 1900 using dodgy arguments which no-one could understand. Planck had quantised the oscillators and regarded this as no more than a “formal procedure”. • There were no papers on quanta until Einstein’s paper of 1905. • Einstein quantised the radiation field rather than the oscillators which are in equilibrium with the radiation. • Among the predictions of the theory was an explanation for the photoelectric effect. 2 Einstein’s Derivation of Planck’s Law (1) In 1906, Einstein realised that he could reformulate Planck’s ideas using Boltzmann’s statistical mechanics properly. The system of oscillators can take only discrete energy levels with energies, 0, ǫ, 2ǫ, 3ǫ, ... Boltzmann’s expression for the probability that an oscillator is in a state with energy E = nǫ in thermal equilibrium at temperature T where n is an integer is p(E) ∝ e−E/kT . Suppose there are N0 oscillators in the ground state, E = 0. Then, the number in the −ǫ/kT −2ǫ/kT n = 1 level is N0 e , the number in the n = 2 level is N0 e , and so on. Therefore, the average energy of the oscillator is found in the usual way: N · 0+ ǫ · N e−ǫ/kT + 2ǫ · N e−2ǫ/kT + ..
