Professor Preston Cloud Professor Preston Cloud (1912-Jl990) (Preston Cloud, a great name in Earth Science is no more, His was a versatile mind which probed into many aspects of Earth history. We pro­ duce below a short life history of the famous professor written specially for the Journal by Somadev Bhattacharji, Professor of Geology, New York State University, Brooklyn, New York.-Ed. With the death of Professor Preston Cloud, Emeritus Professor of Geology at the Department of Geological Sciences, University of California, Santa Barbara~ the Earth Sciences have lost one of their most eminent spokesman. Professor Cloud was born in eastern Massachusetts in 1912. He started his undergraduate study of geology in a one-professor department at George Washing­ ton University at Washington, D.C. while holding a tenuous job in the Smith­ sonian Institution's Natural History Museum during the great depression yea'rs in the U.S.A. This early experience influenced his later career in geology. He graduated from George Washington University in 1938, and continued on to receive his Ph.D. from Yale University at New Haven, Connecticut in 1940. After a long association with the U.S. Geological Survey as a geologist and paleonto­ logist, he retired in 1979. He also taught at the Missouri School of Mines~ Harvard University, The University of Minnesota, and the University of California at both Los Angeles and Santa Barbara. In the last years of his active retired life, Santa Barbara was his base, but he travelled widely to see · real geology' and lectured and inspired many, beside being busy writing. Immediately after his retirement from the USGS, he served for a year each as H. R. Luce Professor of Cosmology at Mount Holyoke College, Massachusetts and as a Queen Elizabeth II Senior Fellow of the Department of Science at the Baas Becking Institute of Geobiology in Canberra, Australia. During his years at Santa Barbara he received many bonors, the highest among them being the PI!nrose Medal of the Geological Society of America, membership of the National Academy of Sciences, U.S.A., and the foreign membership in the Polish Academy of Sciences. Besides being an ardent spokesman for geological sciences, he is best known for his monumental work on biological processes in Earth History and biosphere/geosphere interactions during pre-Phanerozoic time. Among his many works on Earth History, a recent paperbaek Oasis in Space summarizes the way he looked at mother earth. In another short reminiscence about his experience in geology for the young geologists (Compass, 1989), be wrote: 'Geology during the half-century since my school days has undergone a couple of revolutions-not only the plate tectonics revolution, but a geochemical revolution (including geochronology), a marine science revolu­ tion, and a revolution in our knowledge of prc-Phanerozoic history. Geology remains the most interdisciplinary of sciences, only more so'. On specialists and generaJists in geology: ' ... a dedicated specialist may focus on some specific component or process for a life time, with profound and far~reaching results. Generalists reach for broader connections learning new fields and often switch fields in the process. Both are needed, but the best generalists start as specialists-where they gain the necessary depth, and the recognition that evidence take priority in all areas of scientific discourse. Objectivity may be beyond human grasp, but all scientists are obliged to strive for it.' For the geoscientists of today and tomorrow these are cautionary reminders. Preston Cloud-a visionary geologist, outstanding educator and a true scien­ tist, will be terribly missed. .

  • Introduction Big History's Big Potential
    Introduction Big History’s Big Potential Leonid E. Grinin, David Baker, Esther Quaedackers, and Andrey V. Korotayev Big History has been developing very fast indeed. We are currently ob- serving a ‘Cambrian explosion’ in terms of its popularity and diffusion. Big History courses are taught in the schools and universities of several dozen countries, including China, Korea, the Netherlands, the USA, In- dia, Russia, Japan, Australia, Great Britain, Germany, and many more. The International Big History Association (IBHA) is gaining momentum in its projects and membership. Conferences are beginning to be held regularly (this edited volume has been prepared on the basis of the pro- ceedings of the International Big History Association Inaugural Confer- ence [see below for details]). Hundreds of researchers are involved in studying and teaching Big History. What is Big History? And why is it becoming so popular? Accord- ing to the working definition of the IBHA, ‘Big History seeks to under- stand the integrated history of the Cosmos, Earth, Life and Humanity, using the best available empirical evidence and scholarly methods’. The need to see this process of development holistically, in its origins and growing complexity, is fundamental to what drives not only science but also the human imagination. This shared vision of the grand narrative is one of the most effective ways to conceptualize and integrate our growing knowledge of the Universe, society, and human thought. Moreover, without using ‘mega-paradigms’ like Big History, scientists working in different fields may run the risk of losing sight of how each other's tireless work connects and contributes to their own.

    Alles Introductory Biology Lectures An Introduction to Science and Biology for Non-Majors Instructor David L. Alles Western Washington University ----------------------- Part Three: The Integration of Biological Knowledge The Origin of our Solar System and Geologic Time ----------------------- “Out of the cradle onto dry land here it is standing: atoms with consciousness; matter with curiosity.” Richard Feynman Introduction “Science analyzes experience, yes, but the analysis does not yet make a picture of the world. The analysis provides only the materials for the picture. The purpose of science, and of all rational thought, is to make a more ample and more coherent picture of the world, in which each experience holds together better and is more of a piece. This is a task of synthesis, not of analysis.”—Bronowski, 1977 • Because life on Earth is an effectively closed historical system, we must understand that biology is an historical science. One result of this is that a chronological narrative of the history of life provides for the integration of all biological knowledge. • The late Preston Cloud, a biogeologist, was one of the first scientists to fully understand this. His 1978 book, Cosmos, Earth, and Man: A Short History of the Universe, is one of the first and finest presentations of “a more ample and more coherent picture of the world.” • The second half of this course follows in Preston Cloud’s footsteps in presenting the story of the Earth and life through time. From Preston Cloud's 1978 book Cosmos, Earth, and Man On the Origin of our Solar System and the Age of the Earth How did the Sun and the planets form, and what lines of scientific evidence are used to establish their age, including the Earth’s? 1.

  • 2-Web Lecture Notes 2013-3-5
    Lecture Notes for Biology 101: An Introduction to Science and Biology for Non-Majors Instructor David L. Alles Course Outline The organization of this course has been driven by the goal of providing non-majors with a coherent picture of modern biological knowledge. To accomplish this goal it’s necessary that each student gains an appreciation of the nature of science and is introduced to the integrated view of our world that modern science has produced. To facilitate this the course is divided into four parts. Part One: The Nature of Science There are three elements in defining science: 1) the values of science, 2) science as a profession, and 3) the product of science—scientific knowledge. Using this definition, the goal of Part One is to introduce the fundamental nature of the scientific enterprise. Major Units: Defining Science The Epistemic Values of Science The Origin of Modern Science Science as a Profession Part Two: The Conceptual Framework of Biology The goal of Part Two is to introduce the conceptual framework of modern biology. Evolution and historical systems provide the conceptual framework or paradigm for understanding modern biology. But a basic understanding and appreciation of molecular biology is also necessary before we can begin to integrate all of biological knowledge. Major Units: Cosmological Evolution Natural Levels of Organization in the Physical World Biological Evolution Life as a Chemical Function—Biochemistry & Genetics The Modern Synthesis—Darwin and Mendel Part Three: The Integration of Biological Knowledge The purpose of Part Three is to show how biological knowledge can be integrated into a coherent picture of life on Earth.

  • The Cambrian Explosion: How Do We Use the Evidence?
    Teaching Biology The Cambrian Explosion: How Do We Use the Evidence? JEFFREY S. LEVINTON The Cambrian explosion is an excellent example of a grand idea that has been tempered by the steady collection of data to test hypotheses. Historically, the idea of an “explosion” developed from an apparent lack of bilaterian animal fossils before a certain point in the fossil record, in contrast with a great diversity of life that seemed to appear in the Cambrian period. DNA molecular clock estimates contradict this story, however, with most dates for the divergence of major phyla predating the Cambrian by 100 million to 400 million years. The contradiction might be rectified by corrections to the clock or by discoveries of Precambrian bilaterian fossils. Although many candidates exist, no single environmental or biological explanation for the Cambrian explosion satisfactorily explains the apparent sudden appearance of much of the diversity of bilaterian animal life. Scientists’ understanding of this phenomenon has been greatly amplified in recent years by better geological dating and environmental characterization, new fossil discoveries, and by a great expansion of our knowledge of developmental mechanisms and their evolutionary meaning. Keywords: Cambrian explosion, macroevolution, fossil record, molecular evolution he term “Cambrian explosion” refers to a hypoth- in Wales and England revealed a series of animal forms, with Tesized time when bilaterally symmetrical (bilaterian) the newest rocks containing forms that strongly resembled animal groups of diverse forms diverged from a common living animal species, and the oldest including a series of ancestor during the early part of the Cambrian period, a strata that apparently lacked recognizable animal fossils.
