A Newtonian system that mimics the baldness of rotating black holes

Clifford M. Will, Ph.D., the James S. McDonnell Professor of Physics in Arts & Sciences, has shown that even in Newton’s gravity, arrangements of masses exist whose gravitational field also admits a Carter-like constant of motion. The finding has implications for gravitational-wave astronomy, he says.

Washington

To commemorate the 277th anniversary of George Washington’s birth, Washington University in St. Louis scholars will examine the legend versus the real man, and consider whether the philosophical and moral ambiguities he wrestled with during his lifetime have modern connotations.

Primates evolved to be social, not aggressive Sussman tells AAAS

SussmanPrimates are social animals. But why did they become social and what are the causes for the differences in social structure among various primate species? Robert W. Sussman, Ph.D., professor of anthropology in Arts & Sciences, addressed those questions and more in his talk “A Comparative Overview of Primate Social Organization” during the 2009 annual meeting of the American Association for the Advancement of Science Feb. 15 in Chicago.

Biologist discusses sacred nature of sustainability

GoodenoughThe hot topics of global warming and environmental sustainability are concerns that fit neatly within the precepts of religious naturalism, according to Ursula Goodenough, Ph.D., professor of biology in Arts & Sciences at Washington University in St. Louis. In addition to being a renowned cell biologist, Goodenough is a religious naturalist and the author of The Sacred Depths of Nature, a bestselling book on religious naturalism that was published in 1998. Religious naturalism neither requires belief in God nor excludes such faith. Rather, the movement is based on what Goodenough describes as “an exploration of the religious potential of nature.”

Altruistic animals

Wild baboons in Africa forage for food.To watch the 5 o’clock news every night, you’d think man was born to be destructive, violent and antagonistic. But that’s just not the case, argue numerous prominent researchers who will gather at Washington University in St. Louis March 12-14 to discuss the nature of human sociality. The conference, titled “Man the Hunted: The Origin and Nature of Human Sociality, Altruism and Well-Being,” will be the first of its kind to include academics from around the world and across multiple disciplines — anthropology, psychiatry, human evolution, biology, religion, education and medicine — to focus on the evolution of cooperation, altruism and sociality and possible factors that led to the evolution of these characteristics in primates and humans.
