From one of the architects of the new science of simplicity and complexity comes an explanation of the connections between nature at its most basic level and natural selection, archaeology, linguistics, child development, computers, and other complex adaptive systems. Nobel laureate Murray Gell-Mann offers a uniquely personal and unifying vision of the relationship between the fundamental laws of physics and the complexity and diversity of the natural world.
Murray Gell-Mann is one of the leading physicists of the world. He was awarded the Nobel Prize in Physics in 1969 for his work on the classification and symmetries of elementary particles, including the approximate SU(3) symmetry of hadrons. His list of publications is impressive; a number of his papers have become landmarks in physics. In 1953, Gell-Mann introduced the strangeness quantum number, conserved by the strong and electromagnetic interactions but not by the weak interaction. In 1954 he and F E Low proposed what was later called the renormalization group. In 1958 he and R P Feynman wrote an important article on the V-A theory of the weak interaction. In 1961 and 1962 he described his ideas about the SU(3) symmetry of hadrons and its violation, leading to the prediction of the - particle. In 1964 he proposed the quark picture of hadrons. In 1971 he and H Fritzsch proposed the exactly conserved color quantum number and in 1972 they discussed what they later called quantum chromodynamics (QCD), the gauge theory of color. These major publications and many others are collected in this volume, providing physicists with easy access to much of Gell-Mann's work. Some of the articles are concerned with his recollections of the history of elementary particle physics in the third quarter of the twentieth century.
In Quest of the Quark reinforces atomic theory for high school students, and links it with Elementary Particle Physics in a structured way that encourages literacy without heavy mathematics, by interrelating the particles which make up sub-atomic particles. At the beginning of the universe matter/energy were one, and then in the first few micro-seconds of time, they split apart or separated, a process called symmetry splitting in Particle Physics, or more commonly The Big Bang. The particles of matter, called fermions, are the bricks of the universe, and the bosons which transmit the forces of energy, the mortar which binds them together. This fundamental view of our time-continuum is quite elegant in its organization, and startling in its beauty, as the worlds within worlds of fundamental particles are explored.
This proceedings volume from a workshop by the same name sponsored by the Santa Fe Institute in August, 1989, covers a range of disciplines and subdisciplines of relevance to linguistics, phonetics, psycholinguistics, cognitive science, sociolinguistics, archaeological and anthropological linguistics, neuroanatomy, biology, and physics.
This work is a unique introductory A–Z resource detailing the scientific achievements of the contemporary world and analyzing the key scientific trends, discoveries, and personalities of the modern age. * Over 200 A–Z entries covering topics ranging from plate tectonics to the first Moon landings * More than 40 stunning photographs providing a unique pictorial chronicle of the achievements of modern science
"More years ago than I care to reckon up, I met Richard Feynman." So begins THE LANGUAGE GOD TALKS, Herman Wouk's gem on navigating the divide between science and religion. In one rich, compact volume, Wouk draws on stories from his life as well as on key events from the 20th century to address the eternal questions of why we are here, what purpose faith serves, and how scientific fact fits into the picture. He relates wonderful conversations he's had with scientists such as Feynman, Murray Gell-Mann, Freeman Dyson, and Steven Weinberg, and brings to life such pivotal moments as the 1969 moon landing and the Challenger disaster. Brilliantly written, THE LANGUAGE GOD TALKS is a scintillating and lively investigation and a worthy addition to the literature.
South Africa and the Global Hydrogen Economy is the publication of a MISTRA research project on the use of strategic minerals in the global putative hydrogen economy. The book highlights the global significance of platinum group metals (PGM) and explores the strategic opportunities that arise out of South Africa's endowment of these strategic resources. From their extraction to their applications in fuel cells, what options are available for the country, the region and the world to better leverage this endowment towards supporting growth and development objectives? In view of their expanding range of applications, do PGM need the hydrogen economy? Conversely, does the hydrogen economy need PGM? Addressed to all industry stakeholders, including those in the public and private sectors, the options explored in this book are based on a thorough analysis of the global dynamics that should inform policy and business models related to PGM.
