 Free Download Data Analysis: Statistical and Computational Methods for Scientists and Engineers by Siegmund Brandt English | PDF | 1999 | 685 Pages | ISBN : 0387984984 | 44 MB 1. 1 Typical Problems of Data Analysis Every branch of experimental science, after passing through an early stage of qualitative description, concerns itself with quantitative studies of the phe nomena of interest, i. e. , measurements. In addition to designing and carrying out the experiment, an importal1t task is the accurate evaluation and complete exploitation of the data obtained. Let us list a few typical problems. 1. A study is made of the weight of laboratory animals under the influence of various drugs. After the application of drug A to 25 animals, an average increase of 5 % is observed. Drug B, used on 10 animals, yields a 3 % increase. Is drug A more effective? The averages 5 % and 3 % give practically no answer to this question, since the lower value may have been caused by a single animal that lost weight for some unrelated reason. One must therefore study the distribution of individual weights and their spread around the average value. Moreover, one has to decide whether the number of test animals used will enable one to differentiate with a certain accuracy between the effects of the two drugs. 2. In experiments on crystal growth it is essential to maintain exactly the ratios of the different components. From a total of 500 crystals, a sample of 20 is selected and analyzed.

Free Download Ofer Lahav, Lucy Calder, Julian Mayers, "Dark Energy Survey, The: The Story of a Cosmological Experiment" English | 2020 | ISBN: 1786348357, 1800611668 | PDF | pages: 445 | 109.6 mb 'The past cultures of astronomy and physics evolved their own distinct personalities. The book describes an important milestone in the history of the unification of the two fields and provides an excellent summary of the methods used to explore one of the greatest mysteries in physics today: dark energy.'Physics TodayThis book is about the Dark Energy Survey, a cosmological experiment designed to investigate the physical nature of dark energy by measuring its effect on the expansion history of the universe and on the growth of large-scale structure. The survey saw first light in 2012, after a decade of planning, and completed observations in 2019. The collaboration designed and built a 570-megapixel camera and installed it on the four-metre Blanco telescope at the Cerro Tololo Inter-American Observatory in the Chilean Andes. The survey data yielded a three-dimensional map of over 300 million galaxies and a catalogue of thousands of supernovae. Analysis of the early data has confirmed remarkably accurately the model of cold dark matter and a cosmological constant. The survey has also offered new insights into galaxies, supernovae, stellar evolution, solar system objects and the nature of gravitational wave events.A project of this scale required the long-term commitment of hundreds of scientists from institutions all over the world. The chapters in the first three sections of the book were either written by these scientists or based on interviews with them. These chapters explain, for a non-specialist reader, the science analysis involved. They also describe how the project was conceived, and chronicle some of the many and diverse challenges involved in advancing our understanding of the universe. The final section is trans-disciplinary, including inputs from a philosopher, an anthropologist, visual artists and a poet. Scientific collaborations are human endeavours and the book aims to convey a sense of the wider context within which science comes about.This book is addressed to scientists, decision makers, social scientists and engineers, as well as to anyone with an interest in contemporary cosmology and astrophysics.Related Link(s)  Free Download Alan G.

Free Download Susan Thorpe, "Daily Life in Ancient Egyptian Personal Correspondence " English | ISBN: 1789695074 | 2021 | 136 pages | PDF | 3 MB Representations and inscriptions on tomb and temple walls and individual stelae have provided considerable knowledge of ancient Egyptian daily life, religious custom and military achievements. However, as visual or eulogistic textual evidence they are unable to provide the insight into the people themselves, their personalities and the events and issues they were concerned with, insight which can be found in personal correspondence. Daily Life in Ancient Egyptian Personal Correspondence addresses a selection of letters from the Old Kingdom up to and including the Twenty-first Dynasty. Under the topic headings of problems and issues, daily life, religious matters, military and police matters, it will show the insight they provide regarding aspects of belief, relationships, custom and behaviour, evidencing the distinctiveness of the data such personal correspondence can provide as a primary source of daily life in ancient Egypt - the extra dimension.
