The paintings are arranged according to dissimilarity distances, derived from their wavelet transforms, aiming to distinguish paintings by Van Gogh from those by other painters. Curriculum Vitae
Overview - Stephen Hawking's Grand Design on DiscoveryUK In this remarkable new series ‘Stephen Hawking’s Grand Design’ the world’s most famous physicist attempts to unravel the truths behind humanity’s most enduring questions: Did God create the universe? What is the meaning of life? Why does the universe exist? Unfolding his personal, compelling vision of the universe, the eminent British cosmologist evaluates a variety of intricate ideas, from ‘Intelligent Design’ to the impact the search for the Higgs Boson particle at CERN could have on our understanding of the cosmos.
NeuroLogica Blog Jan 13 2017 Cognitive Biases in Health Care Decision Making This was an unexpected pleasant find in an unusual place. The Gerontological Society of America recently put out a free publication designed to educate patients about cognitive biases and heuristics and how they can adversely affect decision making about health care. The publication is aimed at older health care consumers, but the information it contains is applicable to all people and situations. It is a well written excellent summary of common cognitive biases with a thorough list of references. Putting the Future Back in the Room Putting the Future Back in the Room The future that my parents' generation warned us about forty years ago looks an awful lot like our present. The ice caps are melting, deserts are spreading, the planet is thick with people, most of the world's primeval forests are gone, the seas are in crisis, and pollution, famine and natural disasters kill millions of people a year.
Why is Earth Day celebrated on April 22? The first Earth Day – April 22, 1970 – marked the beginning of the modern environmental movement. Approximately 20 million Americans, especially on college campuses, participated in a national teach-in on environmental issues and protests against environmental deterioration on the first Earth Day. It’s hard to imagine it now, but the first Earth Day was a revelation to many, a way not only of raising consciousness about environmental issues but also of bringing together separate groups that had been fighting separately against issues including oil spills, pollutions from factories and power plants, raw sewage, toxic dumps, pesticides, the loss of wilderness, air pollution and more. Since then, Earth Day is always celebrated on April 22. But why April 22?
Statistical Basis for Predicting Technological Progress Forecasting technological progress is of great interest to engineers, policy makers, and private investors. Several models have been proposed for predicting technological improvement, but how well do these models perform? An early hypothesis made by Theodore Wright in 1936 is that cost decreases as a power law of cumulative production. Field Guide to X-ray Astronomy Chemistry and the Universe Chemistry, the study of the intricate dances and bondings of low-energy electrons to form the molecules that make up the world we live in, may seem far removed from the thermonuclear heat in the interiors of stars and the awesome power of supernovas. Yet, there is a fundamental connection between them. To illustrate this connection, the familiar periodic table of elements—found in virtually every chemistry class—has been adapted to show how astronomers see the chemical Universe.
