Introduction to Laser Science and Engineering provides a modern resource for a first course in lasers for both students and professionals. Starting from simple descriptions, this text builds upon them to give a detailed modern physical understanding of the concepts behind light, optical beams and lasers. The coverage starts with the nature of light and the principles of photon absorption and transmission, leading to the amplified and stimulated emission principals governing lasers. The specifics of lasers and their application, safe use and future prospects are then covered, with a wealth of illustrations to provide readers with a visual sense of optical and laser principles.

Introduction to Rocket Science and Engineering, Second Edition, presents the history and basics of rocket science, and examines design, experimentation, testing, and applications. Exploring how rockets work, the book covers the concepts of thrust, momentum, impulse, and the rocket equation, along with the rocket engine, its components, and the physics involved in the generation of the propulsive force. The text also presents several different types of rocket engines and discusses the testing of rocket components, subsystems, systems, and complete products. The final chapter stresses the importance for rocket scientists and engineers to creatively deal with the complexities of rocketry.

Don't mess with our astronauts! A Russian ICBM site is attacked just north of the Ukraine boarder. The nuclear warheads are missing! A Special Operations and Intelligence Community Task Force is rapidly put together to respond, but where it should deplo

Brilliant scientist and government operative Dr. Reagan "Ray" Brady should be dead. Instead, Ray has the perfect life, working for an ultra-secret division of DHS, watching for invasion by extraterrestrials and time travelers. This team includes his wife, Samantha Brady. The team's "mascot" is their one-year-old daughter, Abigail. When a mysterious man shows up, leaving several dead, Ray's team confronts him in NYC, where the man leaps from the roof of a ten-story building - and vanishes in mid-air. Seconds later, Samantha sees video of the same man touring the Y-12 Plant in Oak Ridge, Tennessee. A genetic scientist disappears from his locked office. Gold and other items, including fissile material from Oak Ridge, are vanishing around the world.Who is this man? What does he intend to do with all of the stolen wealth and dangerous material he has amassed? And can Ray and his team stop him?

When Kyle Leverson, prematurely retired from the U.S. Army after being injured in combat, and living alone in a remote spot in the mountains of northern Arkansas, goes to investigate on hearing a thud outside his home, he finds, to his shock, that an alien has landed in his garden, after a malfunction in its unreality-drive exploration starship. This is not a War of the Worlds scenario, though. The alien was hurt during its enforced descent to Earth, when its fast-disintegrating lifepod dropped through the canopy of the pine trees on the mountainside and dumped it right beside Kyle's house. When Kyle nervously rescues the wounded creature and takes it into his home to see if he might be able to help it, it is grateful for his assistance--very grateful.
