Newton Sims on Victoria Creek (New Helena), Custer County, Nebraska
No full textPhotographer's annotation: 'House built by J. Merchant first in creek. Had underground passage dug to spring so if attacked by Indians could not be cut off from water supply, 1886.' Denise and Daryl Andersen identify the family as Issac Newton Sims, his two sons Theodore and George, and wife Clarinda. They lived in Anselmo in 192
The system of the world 宇宙体系
No full textThe System of the World, Isaac Newton's first draft for the third volume of his classic work Philosophiae Naturalis Principia Mathematica (1687; Mathematical Principles of Natural Philosophy), is an important document in the history of science, using the principles of mechanics to construct the first complete scientific system on the workings of the universe in human history.
This book of 78 treatises briefly describes the principles established in the first two volumes of the Mathematical Principles of Natural Philosophy, then applies these principles to the derivation of the actual orbits of the solar system and comets, laying out in layman's terms the universality of the law of gravitation and, from this, studying the shape of the earth, explaining the planetary precession and the tides of the oceans, probing the motion of the moon, and determining the orbits of comets. In this book, Newton does not construct abstract mathematical models, but analyses them in relation to astronomical phenomena, using only a small amount of mathematical language to explain these intriguing elements, making its content suitable for a general audience.
The appendices of this Chinese translation by Haixuan Pan(潘海璇) include Life of Sir Issac Newton by N. W. Chittenden, Newtonian Studies by Alexandre Koyré, which introduce Newton's life and main achievements, as well as the debates and evaluations of the main academic views of Newton by the leading philosophers and scientists of the time, and are important supplementary and reference materials when reading The System of the World
Newton's Laws
No full textAuthored and curated by David P. Stern, this series of web pages, part of "From Stargazers to Starships," describes Newton's three laws of motion and the two concepts on which they are based, force and inertia. The author breaks down the page in this fashion: the concept of force, motion against outside resistance, and motion with significant resistance. The author also provides additional links for further study on the life of Issac Newton. A lesson plan for instructors is also provided
Isaac Newton
No full textIssac (Ike) Newton came to Vernal in 1902. He and his brother Bill, fournded and operated the Newton Brother Saddle Company. He worked at the saddle shop even when he began to loose his sight and became nearly completely blind. He died in June 1949
Further developments of optical fibre techniques for astronomical spectroscopy
No full textThis thesis describes instrumental techniques pursued to optimise the quality of the spectroscopic data which will be obtained via the new generation of multifibre systems. The technical aspects discussed include the instrumental sources of systematic errors on sky subtraction and new methods to evaluate the fibre performance in terms of throughput and preservation of the input focal ratio. The limiting factor in faint multifibre spectroscopy is the accuracy and reliability of sky subtraction. Instrumentality the precision to which sky subtraction can be done is limited by systematic errors. The conditions that have to be satisfied to subtract the sky properly at faint levels, the sources of errors and possible ways of eliminating them are analysed. A comprehensive discussion of the effect of deficient wavelength sampling and of poor fibre flatfield calibration on sky subtraction is provided via computer simulations of fibre data. Several laboratory fibre evaluation techniques and data processing software packages have been developed. These techniques have been used to measure the through put of silica fibres at optical wavelengths. Also presented in this thesis are preliminary results obtained from a series of experiments implemented at infrared wavelengths. As a result of these developments a new method for determining the focal ratio degradation (FRD), based on a known theoretical model for microbending induced beam- spreading is proposed. This theory characterises the FRD by a single parameter which can be determined by a very simple experiment. The model successfully predicts real experimental results. This new technique will allows us to accurately model the complete performance of any fibre. Such modelling can include complicated phenomena such as tilted input beams and central obstructions without the need to setup experiments for specific cases. Furthermore, it can be used to evaluate the performance of infrared fibres. Finally, the results of an exhaustive laboratory evaluation of the Autofib-1.5 fibre bundle are presented. The evaluation was carried out after a multiway fibre connector prototype was incorporated into the Autofib-1.5 fibre bundle, with the emphasis being placed on the performance of the connector

De las Leyes de Newton a la Guerra de Troya
No full textLa publicación en 1687 del libro Philosophia Naturalis Principia Mathematica por Issac Newton marcó un importante hito en la historia del pensamiento humano. Sobre la base de tres sencillos principios de movimiento y de la ley de gravitación universal, y mediante razonamientos matemáticos, Newton logró explicar y unificar dentro de un esquema conceptual coherente una gran cantidad de fenómenos naturales: el movimiento de los planetas, las mareas, la forma de la Tierra, entre otros. Más aún, Newton mostró que los principios que rigen el movimiento de los astros también son válidos en el ámbito terrestre. Las mismas leyes que determinan, por ejemplo, el movimiento de la Luna también se aplican a las balas de cañón. La mecánica newtoniana no dio solamente una explicación cualitativa de estos fenómenos. Los métodos matemáticos empleados por Newton permitieron hacer predicciones cuantitativas precisas que podían contrastarse con la observación y con la experimentación.Facultad de Ciencias Astronómicas y Geofísica
