“Lt Colonel Dan Rooney is a true patriot who serves our country with courage and honor.”—George H.W. Bush, 41st President…
of the United States F-16 fighter pilot, American hero, Folds of Honor founder, PGA professional, and inspirational family man Dan Rooney delivers a motivational code for living to help ordinary people ascend to their highest level in life. Part spiritual guide and part call-to-action, Fly Into the Wind combines Lt Colonel Rooney’s fighter pilot stories with his discovery of faith and purpose in order to help each reader achieve a philosophy he calls CAVU, after the Air Force acronym that stands for “ceiling and visibility unrestricted.” CAVU describes the perfect conditions for flying a fighter jet, when steel-blue skies invite pilots to spread their wings like supersonic eagles. In today’s world of identity politics, fractured racial relations, and external turmoil, Rooney’s book will show how all of us are connected by God in more ways than we realize, and that the path to fulfillment begins with changing ourselves in order to better one another. From the outside, Lieutenant Colonel Dan “Noonan” Rooney was living the American Dream: he was an F-16 fighter pilot, PGA Professional, husband to his college sweetheart, and father of five daughters. His position in life should have been a blessing. But a near-tragic mishap while piloting his F-16 triggered an ominous life storm that altered his trajectory and filled him with self-doubt. Realizing that a jet takes off into the wind because it requires resistance over its wings to fly, Lt Colonel Rooney’s attitude toward the resistance he encountered in his life changed from resentment to humble introspection. Hyper-focused on the precise areas that are immediately under your control, CAVU is a disciplined approach to each day that will help you reshape, motivate, prioritize, and ultimately thrive. In Fly Into the Wind, Lt. Colonel Rooney breaks down CAVU into ten unique lines of effort (LOE), with each LOE building upon the previous one to provide a positive vector toward a new way of living. Along this enlightened path, readers will discover a renewed belief in themselves and the art of the possible. The time for self-discovery and ultimate achievement begins now.By Mircea S. Rogalski, Stuart B. Palmer. 1999

Long before history began to be recorded, man strove constantly to get plants that would produce greater amounts of food…
with less labor. Sometimes he obtained this improvement by increasing the food-producing ability of an existing plant, at other times by selecting a more capable new plant. Hybrid corn is the greatest example in recent time of increasing the value of a food-bearing plant by improving one already in common use. The development of hybrid corn is truly one of the most important advances made in all the thousands of years since man first began cultivating special food-bearing plants.What is hybrid corn, and how does it differ from the corn grown before it was developed?By Arash Azizi. 2020

military spearhead for Iranian foreign policy, he enacted the wishes of the country&’s Supreme Leader, establishing the Islamic Republic as a major force in the Middle East. He masterminded interventions in Afghanistan, Iraq, Lebanon, Syria and Yemen, supporting Iran&’s allies and campaigning against the Taliban, US forces, Israel and ISIS. But all this was a long way from where he began – on the margins of a country whose ruler was regarded as a friend of the West. In this gripping account, Arash Azizi examines Soleimani&’s life, regional influence and future ambitions. He breaks new ground through interviews with Iranians, Afghans, Iraqis and Syrians who knew Soleimani for years, including his personal driver, the aides who accompanied him to his Moscow meeting with Vladimir Putin, and his brother. Through Soleimani, Azizi reveals the true nature of Iran&’s global ambitions, providing a rare insight into a country whose actions are much talked about but seldom understood.By Douglas McKie. 2020
ANTOINE LAURENT LAVOISIER is heralded as the founder of modern chemistry whose genius was cut short by the brutal Revolutionary…
terror of the French Revolution. "Only a moment to chop off that head," said Lagrange the mathematician to Delambre, one of the inventors of the metric system, "and a hundred years may not give us another like it."Until Antoine Lavoisier, all matter was believed to be composed of four elements: earth, water, air and fire. It was Lavoisier who first showed that Nature was made out of much more complicated stuff, and that bodies burn not by releasing their fire element, but by combining with the element oxygen, the same element that enables plants and animals to breathe.By W. T Welford. 1986

This book provides an in-depth and accessible description of special relativity and quantum mechanics which together form the foundation of…
21st century physics. A novel aspect is that symmetry is given its rightful prominence as an integral part of this foundation. The book offers not only a conceptual understanding of symmetry, but also the mathematical tools necessary for quantitative analysis. As such, it provides a valuable precursor to more focused, advanced books on special relativity or quantum mechanics.Students are introduced to several topics not typically covered until much later in their education.These include space-time diagrams, the action principle, a proof of Noether's theorem, Lorentz vectors and tensors, symmetry breaking and general relativity. The book also provides extensive descriptions on topics of current general interest such as gravitational waves, cosmology, Bell's theorem, entanglement and quantum computing.Throughout the text, every opportunity is taken to emphasize the intimate connection between physics, symmetry and mathematics.The style remains light despite the rigorous and intensive content. The book is intended as a stand-alone or supplementary physics text for a one or two semester course for students who have completed an introductory calculus course and a first-year physics course that includes Newtonian mechanics and some electrostatics. Basic knowledge of linear algebra is useful but not essential, as all requisite mathematical background is provided either in the body of the text or in the Appendices. Interspersed through the text are well over a hundred worked examples and unsolved exercises for the student.By Pablo Artal. 2017
