Free Download Claude AI for Beginners: A Practical Guide to Anthropic's Assistant English | Nov 29, 2025 | ISBN: 9798232040376 | 152 pages | EPUB (True) | 3.73 MB Claude AI for Beginners  Free Download Classical Optics and Electromagnetic Waves English | 2025 | ISBN: 1032766174 | 737 pages | True PDF,EPUB | 51.21 MB Classical Optics and Electromagnetic Waves offers an exploration of optics, the physics subfield examining light's properties and applications. Beginning with the mathematical foundations of electromagnetic waves in matter, the text develops geometric optics as the short-wavelength limit of Maxwell's Equations, establishing a framework for understanding wavefronts, light rays, and intensity variations. The work progresses methodically through image formation using mirrors and lenses in the paraxial approximation, employing transfer matrices for precise calculations. It thoroughly examines wave propagation through the Huygens-Fresnel and Fresnel-Kirchhoff integrals, comparing scalar and vector-field approaches while demonstrating their reduction to geometric optics. Diffraction receives comprehensive treatment across various scenarios-infinite slits, circular apertures, barriers, and gratings. The text introduces coherence concepts before exploring interference phenomena, developing the amplitude autocorrelation function and its connection to power spectra through the Wiener-Khinchin Theorem. Advanced topics include detailed analysis of Michelson and Fabry-Perot interferometers, thin-film stack calculations using the Abeles transfer matrix technique, Gaussian beam wave functions, optical cavity properties, and Fourier optics. End-of-chapter guided problems, numerous appendices and a glossary of symbols make this an invaluable textbook for intermediate to advanced students of classical optics. Designed as a natural follow-on to Purcell and Morin's Electricity and Magnetism in a three-semester honours sequence, this text bridges introductory electromagnetism and specialized optics coursework. It also serves as a more mathematically rigorous alternative to Hecht's Optics for upper-division students who have completed one or more intermediate-level electromagnetism courses.  Free Download Classical Mechanics by Christopher W. Kulp, Vasilis Pagonis English | August 21, 2025 | ISBN: 1032590513 | 608 pages | MOBI | 11 Mb Classical Mechanics: A Computational Approach with Examples using Python and Mathematica provides a unique, contemporary introduction to classical mechanics, with a focus on computational methods.

Free Download Michael Armitage - Classic RAF Battles from World War One to the Present Brockhampton Press | 2002 | ISBN: 186019897X | English | 180 pages | PDF | 112.43 MB The Royal Air Force has earned its celebrated reputation for excellence and courage over seven decades of service to Britain, through two World Wars and many small incidents, events and flash-points the world over. In compiling this superb visual testament to the RAF, the general aim has been to capture the very reason for the RAF's existence - the combat actions which have given it such an historic tradition of defence to the nation. Some scenes are of general campaigns or aspects of the RAF's history; most, however, are of specific raids, operations or incidents; but they all demonstrate the variety of locations, task's and aircraft types that feature in the RAF's reputation.

Free Download Tom Lund - Classic American Airplanes Virtualbookworm.com Publishing | 2014 | ISBN: 1621375986 | English | 348 pages | PDF | 154.26 MB The United States has a rich history of airplanes beginning with the Wright Flyer and continuing on to the impressive SR-71 Blackbird and to capable passenger and military airplanes of today. A few of the many different airplanes developed in the United States have become classics. The author selected 14 of these airplanes including the Wright Flyer, Curtiss JN-4 Jenny, Spirit of St. Louis, Douglas DC-3, and the Lockheed SR-71 for description in this book. The book gives a concise description of the physical and performance characteristics of each airplane as well as its most important design features. The Wright Flyer was the first airplane to take off under its own power; be controllable in pitch, yaw, and roll and land safely. At the opposite end of performance, the SR-71 was the fastest and highest flying airplane in the world. Speed and altitude records of 2,193 mph and 85,069 feet in level flight set in 1976 still stand.
