Conversations On The Dark Secrets Of Physics

The idea for this book began over four decades ago when Edward Teller began teaching physics appreciation courses at the University of Chicago. Then, as now, Dr. Teller believes that illiteracy in science is an increasingly great danger to American society, not only for our chil dren but also for our growing adult population. On one hand, the future of every individual on this globe is closely related to science and its applications. Fear of the results of science, which has become prevalent in much of the Western World, leads to mistaken decisions in important political affairs. But this book speaks of no fears and of no decisions-only of the facts that can prevent one of them and indirectly guide the others. From the perspective of this book, a second point is even more vii viii PREFACE significant. The first quarter of this century has seen the most won derful and philosophically most important transformation in our thinking. The intellectual and aesthetic values of the points of view of Einstein and Bohr cannot be overestimated. Nor should they be hidden at the bottom of tons of mathematical rubble. Our young people must be exposed to science both because it is useful and because it is fun. Both of these qualities should be taken at a truly high value.

This unified treatment of electromagnetic, hadronic and gravitational radiation processes associated with relativistic outflows from compact objects is ideal for researchers interested in the transient universe. It examines relativistic outflows and radiation processes and links contemporary astronomy to gravitational-wave experiments.

The announcement in 2012 that the Higgs boson had been discovered was understood as a watershed moment for the Standard Model of particle physics. It was deemed a triumphant event in the reductionist quest that had begun centuries ago with the ancient Greek natural philosophers. Physicists basked in the satisfaction of explaining to the world that the ultimate cause of mass in our universe had been unveiled at CERN, Switzerland. The Standard Model of particle physics is now understood by many to have arrived at a satisfactory description of entities and interactions on the smallest physical scales: elementary quarks, leptons, and intermediary gauge bosons residing within a four-dimensional spacetime continuum. Throughout the historical journey of reductionist physics, mathematics has played an increasingly dominant role. Indeed, abstract mathematics has now become indispensable in guiding our discovery of the physical world. Elementary particles are endowed with abstract existence in accordance with their appearance in complicated equations. Heisenberg’s uncertainty principle, originally intended to estimate practical measurement uncertainties, now bequeaths a numerical fuzziness to the structure of reality. Particle physicists have borrowed effective mathematical tools originally invented and employed by condensed matter physicists to approximate the complex structures and dynamics of solids and liquids and bestowed on them the authority to define basic physical reality. The discovery of the Higgs boson was a result of these kinds of strategies, used by particle physicists to take the latest steps on the reductionist quest. This book offers a constructive critique of the modern orthodoxy into which all aspiring young physicists are now trained, that the ever-evolving mathematical models of modern physics are leading us toward a truer understanding of the real physical world. The authors propose that among modern physicists, physical realism has been largely replaced—in actual practice—by quasirealism, a problematic philosophical approach that interprets the statements of abstract, effective mathematical models as providing direct information about reality. History may judge that physics in the twentieth century, despite its seeming successes, involved a profound deviation from the historical reductionist voyage to fathom the mysteries of the physical universe.

This proceedings volume, for the symposium in honor of Edward Teller's 100th anniversary, focuses on Teller's scientific legacy. This legacy includes some of the most fundamental insights into the quantum behaviors of molecules, nuclei, surfaces, solid state and spin systems and plasmas. Many of these are brand names from the canon of 20th-century physics and chemistry, such as Gamow-Teller transitions, the Jahn-Teller effect, Goldhaber-Teller resonances, the Lyddane-Sachs-Teller relation, the Brunauer-Emmett-Teller equation of state, and the MR2T2 algorithm. All of these have had a profound and continuing impact on science - as has Teller's work on level crossing, diamagnetism, and plasma and statistical physics. The legacies of these discoveries are discussed in this volume, as is Teller's role in applied science and education.

If science has the equivalent of a Bloomsbury group, it is the five men born at the turn of the twentieth century in Budapest: Theodore von Kármán, Leo Szilard, Eugene Wigner, John von Neumann, and Edward Teller. From Hungary to Germany to the United States, they remained friends and continued to work together and influence each other throughout their lives. As a result, their work was integral to some of the most important scientific and political developments of the twentieth century. István Hargittai tells the story of this remarkable group: Wigner won a Nobel Prize in theoretical physics; Szilard was the first to see that a chain reaction based on neutrons was possible, initiated the Manhattan Project, but left physics to try to restrict nuclear arms; von Neumann could solve difficult problems in his head and developed the modern computer for more complex problems; von Kármán became the first director of NASA's Jet Propulsion Laboratory, providing the scientific basis for the U.S. Air Force; and Teller was the father of the hydrogen bomb, whose name is now synonymous with the controversial "Star Wars" initiative of the 1980s. Each was fiercely opinionated, politically active, and fought against all forms of totalitarianism. Hargittai, as a young Hungarian physical chemist, was able to get to know some of these great men in their later years, and the depth of information and human interest in The Martians of Science is the result of his personal relationships with the subjects, their families, and their contemporaries.

For many college students, studying the hard sciences seems out of the question. Students and professors alike collude in the prejudice that physics and molecular biology, mathematics and engineering are elite disciplines restricted to a small number with innate talent. Gregory Light and Marina Micari reject this bias, arguing, based on their own transformative experiences, that environment is just as critical to academic success in the sciences as individual ability. Making Scientists lays the groundwork for a new paradigm of how scientific subjects can be taught at the college level, and how we can better cultivate scientists, engineers, and other STEM professionals. The authors invite us into Northwestern University’s Gateway Science Workshop, where the seminar room is infused with a sense of discovery usually confined to the research lab. Conventional science instruction demands memorization of facts and formulas but provides scant opportunity for critical reflection and experimental conversation. Light and Micari stress conceptual engagement with ideas, practical problem-solving, peer mentoring, and—perhaps most important—initiation into a culture of cooperation, where students are encouraged to channel their energy into collaborative learning rather than competition with classmates. They illustrate the tangible benefits of treating students as apprentices—talented young people taking on the mental habits, perspectives, and wisdom of the scientific community, while contributing directly to its development. Rich in concrete advice and innovative thinking, Making Scientists is an invaluable guide for all who care about the future of science and technology.
