Extractions: Principle Investigator: Prof. Francis Everitt, Stanford University The Satellite Test of the Equivalence Principle, commonly known as STEP, is a project sponsored jointly by NASA and the European Space Agency to greatly improve the test that Galileo conducted at the leaning tower of Pisa: Do all objects fall with the same acceleration due to gravity? The answer to this question relates to whether an object's gravitational mass is the same as, or equivalent to, its inertial mass. The experiment plans to fly several pairs of masses on a drag-free satellite in low Earth orbit, with a launch planned for after 2006. It may surprise you to learn that so great a thinker as Aristotle believed that heavier objects would fall faster, the rate of acceleration being proportional to the weight. These thoughts from the Greek Golden Age prevailed for about 2000 years until courageous scientists like Galileo began to challenge the orthodoxy of physics beliefs. Galileo's purported test in 1620 at the Tower of Pisa to drop a musket ball and a much heavier cannon ball, with the result that the two landed "within a hand's-breadth" of each other, showed two results: If wind resistance is small, then lighter and heavier objects of the same material will fall at the same rate; and, this result is independent of the compositions of the two objects.

Extractions: N. Domenico INTRODUCTION Of some 14 gravity-measuring instruments at the SEG Museum in the Cecil and Ida Green Tower in Tulsa, Oklahoma, perhaps the most eye-catching is the torsion balance (Figure 1). Constructed in 1902, the "Eotvos-Suess Small Visual Torsion Balance" is one of the earliest portable instruments of this type. Its design is based on that used by French physicist Charles Augustine de Coulomb in 1786 to measure distortion of the earths gravitational field, specifically, the differential curvature or warping of an equipotential surface. The design was further developed in 1890 by Baron Roland von Eotvos, a physics professor at the University of Budapest, who wished to determine the earths departure from a sphere by measuring spatial variations of gravity. Eotvos is believed to be the first to propose that the torsion balance be used in exploration for subterranean features. PDF version of this manuscript Publications Meetings Technical ...

GST Timelines -- put DeGolyer in touch with roland von eotvos. He immediately contacted eotvos for a bid on a torsion starting of the new company and DeGolyers contact with eotvos in 1914 http://gst.seg.org/TL/2001/03/TidBits.shtml
Extractions: Oklahoma Geological Survey Through Lord Cowdray, DeGolyer got in touch with two members of the Physics Department at Cambridge University in 1919. DeGolyer spent time talking with these faculty members about sound ranging studies conducted during the war. He also discussed with them the possibility of locating salt domes in coastal Texas and Louisiana with the Eotvos torsion balance and also with some form of seismograph. In addition, DeGolyer discussed these ideas with a Dr. Erb, a chief geologist for Shell. Remember that DeGolyer tried to get one of the torsion gravimeters before the war. Now he could move more aggressively toward acquiring new technology to enhance finding oil and gas reservoirs than he could when World War I was starting earlier. In the early part of this story DeGolyer met his wife, by seeking to meet the German tutor for his German class at OU. Later he met the head of the USGS by planting some beer in a nearby stream. You can imagine that his meeting with Karcher was no accident either. He was actively looking for Karcher when the two met. The two of them worked together to make geophysical history. Our next history section will discuss Karcher's early life that led to the first seismic reflection company in history and how DeGolyer and Karcher met to become partners.

Extractions: Abstract The small deviation in the direction of accelerations he was able to detect sounds still formidable (1/60000 arc second in those early measurements!). The EPF experiment was extensively discussed and became widely known during the last seven years due to the Fifth Force suggestion of E. Fischbach et al. ( In the field of gravity, his measurements of G should be mentioned. First he used the Cavendish method, but optimized the position of the attracting mass so that the dependence on positional uncertainty should be minimum. Later he used various static and dynamical methods. One of his measurements involved a suspended horizontal rod between two massive lead columns. Oscillation times were measured for equilbrium positions both parallel and perpendicular to the separation of the lead columns (640 and 860 s respectively). Then the lead columns were removed, and the measurements reiterated. There was still some difference due to inhomogeneities of the local gravitational field, but that latter measurement could now be used for correction. A relative precision in G of 1/500 was achieved. 5. Shape of the Earth, Geodesy

Extractions: January 15, 1986 West Lafayette, Ind.When Aaron Szafer first saw the results, he couldn't believe his eyes. "We were absolutely stunned. We were surprised to find such direct evidence of a new force from a classical experiment that was believed to rule out such a possibility," says Szafer, a Purdue University doctoral student. Szafer was part of the team that conducted a series of studies that has lead to evidence of a fifth force of physics. The new force, dubbed hypercharge, challenges Galileo's 400-year-old findings on the force of gravity. Under the direction of Purdue Physics Professor Ephraim Fischbach, Szafer and his co-workers, Daniel Sudarsky and Carrick Talmadge of Purdue and S. H. Aronson of the Brookhaven National Laboratory in New York, reanalyzed results from a 1922 experiment conducted by the Hungarian scientist Roland von Eotvos. The results of their study were published in the Jan. 6 issue of "Physical Review Letters." "Eotvos' study was considered one of the classical verifications for Galileo's theory of gravitation," says Szafer. Galileo had predicted that, in a vacuum, gravity would work equally on all objects, causing them to fall to earth at the same rate of speed. Eotvos tested this theory, using objects of different composition and weights, and believed he found results in agreement with Galileo's theory.
ONE HUNDRED YEARS OF THE EOTVOS EXPERIMENT* Inspired by the beauty of the Newtonian system, Baron roland von Eötvös experimentallyinvestigated the proportionality of inertial and gravitating masses in http://www.kfki.hu/~tudtor/eotvos1/onehund.html
Extractions: Appendix I ) for the following task: " A very sensitive method was given by Eötvös to make a comparison between the inertia and gravity of matter. Considering this and the new development of electrodynamics as well as the discovery of radioactive substances, Newton's law concerning the proportionality of inertia and gravitation is to be proved as extensively as possible." . Its motto was "Ars longa, vita brevis" Appendix I we reprint the text of this evaluation. , taken from the original manuscript has been reprinted in English in Budapest in 1963 (with a German abstract, reprinted in Appendix II ). Renner claimed an empirical accuracy of 1/2 000 000 000 to 1/5 000 000 000. Acknowledging the basic role played by the connection between inertial mass and gravitating mass in General Relativity, P. G. Roll, R. Krotkov and R. H. Dicke carried out a new experiment, using modern technology, and achieved an accuracy of 1/100 000 000 000 . However, since no error is quoted and few other details of their analysis are presented, it is difficult to know precisely how the sensitivity of this part of their experiment compared with that of their more extensive work measuring accelerations to the

Extractions: Chronology of Gravitational Physics and Relativity Ismael Bullialdus suggests an inverse-square gravitational force law. Isaac Newton deduces the inverse-square gravitational force law from the "falling'' of the Moon. Isaac Newton proves that planets moving under an inverse-square force law will obey Kepler's laws. Isaac Newton uses a fixed length pendulum with weights of varying composition to test the weak equivalence principle to 1 part in 1000. Henry Cavendish measures the gravitational constant. Urbain Leverrier observes a 35'' per century excess precession of Mercury's orbit. William Clifford suggests that the motion of matter may be due to changes in the geometry of space. Simon Newcomb observes a 43'' per century excess precession of Mercury's orbit. Albert Michelson and Edward Morley do not detect the ether drift. Roland von Eotvos uses a torsion fiber balance to test the weak equivalence principle to 1 part in one billion. Ernst Mach states Mach's principle; first constructive attack on the idea of Newtonian absolute space. Albert Einstein completes his theory of special relativity and states the law of mass-energy conservation.

Extractions: By Gordon Cope The story of geophysics in Canada is a tale of many facets; the triumph of immense oil and gas discoveries and the tragedy of calamities. But most of all, it is a story of ingenuity, perseverance and inspiration. EARLY EXPLORATION The earliest discoverers of oil in North America were Aboriginal Americans, who, from time immemorial, collected the black, viscous fluid from natural ground seeps and used it for medicinal purposes. By the turn-of-the-century, however, most oil seeps had been exploited. Having learned that the low-gravity substance tended to migrate toward the surface unless impeded by a physical barrier, geologists turned to mapping structural features. One area that held great promise was Turner Valley, in the foothills of the Alberta Rockies. Many of the sediments that comprised the Rockies were porous enough to make excellent reservoirs and the thrust and anticlinal features readily apparent from mapping supplied the closure necessary for accumulation. In 1914, Dingman # 1 well produced condensate so pure that it could be fed directly into the gas tank of a Model T Ford. The rolling countryside was soon dotted with rigs, and production soon peaked at 15,000 barrels per day. At the advent of the first world war, however, demand began to exceed supply, especially as the automobile became popular. Oil companies needed a more sophisticated way to effectively and efficiently penetrate the ground and identify oil traps.

Extractions: Quantum cosmology is the term applied to the efforts being made to find a common framework for two vastly different areas of scientific theory: the submicroscopic world of QUANTUM MECHANICS, and the universe-embracing phenomena addressed by modern COSMOLOGY. The cosmological theories that currently prevail are based on general RELATIVITY, which may be characterized as Albert Einstein's theory of GRAVITATION. The basic aim of quantum cosmology, therefore, is to develop a quantum theory of gravitation, but thus far this has proved enormously difficult. Concepts arising from theoretical work in this field are equally difficult, such as that the known universe might be only one of a literally infinite labyrinth of universes
