Matthew P Wiener < weemba@sagi.wistar.upenn.edu > Geoffrey A Landis < Geoffrey.Landis@sff.net > To begin with, the speed of gravity has not been measured directly in the laboratory---the gravitational interaction is too weak, and such an experiment is beyond present technological capabilities. The "speed of gravity" must therefore be deduced from astronomical observations, and the answer depends on what model of gravi Read More Go to Site


		Gravity ^Votes:0 Next: Newton's Law of Gravity Up: Physics 1501 - Modern Previous: Questions Gravity In the 17th century, Sir Isaac Newton formulated his Law of Universal Gravitation to explain the observed motions of astronomical objects such as the moon and the planets. In this Chapter we will see how that this law, when supplemented with Newton's other laws, accurately describes the orbital motion of satellites and planets. We will also point out the deficiencies in Newton's theory that led Einstein to formulate his General Theory of Relativity. Einstein's theory radically altered our view of space and time, and predicted, among other things, the existence of black holes.

		Interactive Experiments in Gravity ^Votes:0 Interactive Experiments in Gravity This directory contains documents and interactive Java applets which explore aspects of both Newton's theory of universal gravitation and Einstein's general relativity. The first two installments in the series are now available. Bending Spacetime in the Basement We live our entire lives within the Earth's gravitational field, yet rarely if ever do we experience the universality of gravitation: that every object in the universe attracts and is attracted by every other. This page presents a "basement science" experiment which reveals the gravitational attraction between objects less than a kilogram in mass. Knowledge in antiquity suggesting gravitation was universal is discussed, and the feasibility of an experimental test using only materials and technique Read More Go to Site

		MykoWeb: Mushrooms, Fungi, Mycology ^Votes:0 Introduction Welcome to MykoWeb , WWW pages devoted to the science of mycology (the study of the fungi) and the hobby of mushrooming (the pursuit of mushrooms). It is a production of Michael Wood , a past president of the Mycological Society of San Francisco . MykoWeb was started in the fall of 1995 and was one of the first internet mycology mushrooming sites. The Fungi of California The main attraction at MykoWeb is The Fungi of California , an expanded version of the former "Fungi of the San Francisco Bay Area". The Fungi of California contains photographs over 500 species of fungi found in California, with over 410 of the species with descriptions. There are currently over 3000 total photographs of the mushrooms. Included are links to other online descriptions and photos of th Read More Go to Site

		Natural Perspective ^Votes:0 Page 1 of 38 Natural Perspective (Last modified: 13 May 2000; latest additions to site : 1 Oct 2007) [ Plantae ] [ Fungi ] [ Animalia ] [ Protoctista ] [ Biosphere ] Monthly Feature: The Plant Kingdom This site is dedicated to the beauty and science of nature and to the joys nature brings to those who explore it. The joy of seeing "familiar faces" everywhere; the invigoration a nature walk brings to both body and soul; the beauty and diversity of our Earthly co-habitants; and the pleasure of eating something found along the way. The material here is organized according to the biological principles of Taxonomy, or classification: We live on a planet called Earth. Biologists call the Earth and its atmosphere -- the Biosphere . The Biosphere is composed of organic and inorganic matter. Organi Read More Go to Site

		Spacetime Wrinkles ^Votes:0 Expo/Science & Industry/Spacetime Wrinkles SPACETIME WRINKLES In 1905, Albert Einstein published his famous Special Theory of Relativity and overthrew commonsense assumptions about space and time. Relative to the observer, both are altered near the speed of light: distances appear to stretch; clocks tick more slowly. A decade and a year later, Einstein further challenged conventional wisdom by describing gravity as the warping of spacetime, not a force acting at a distance. Since then, Einstein's revolutionary insights have largely stood the test of time. One by one, his predictions have been borne out by experiment and observation. But it wasn't until much later that scientists accepted one of the most dramatic ramifications of Einstein's theory of gravitation: the existence of black hole Read More Go to Site
