"A Prelude to Quantum Field Theory offers a short introduction to quantum field theory (QFT), a powerful framework for understanding particle behavior that is an essential tool across many subfields of physics. A subject that is typically taught at the graduate level in most physics departments, quantum field theory is a unification of standard quantum theories and special relativity, which depicts all particles as "excitations" that arise in underlying fields. It extends quantum mechanics, the modern theory of one or few particles, in a way that is useful for the analysis of many-particle systems in the real world. As it requires a different style of thinking from quantum mechanics, which is typically the undergraduate physics student's first encounter with the quantum world, many beginners struggle with the transition to quantum field theory, especially when working with traditional textbooks. Existing books on the subject often tend to be large, sophisticated, and complete; and an overwhelming wealth of information and technical detail makes it difficult for the novice to discern what is most important. This book is a concise, friendly entrée for QFT-beginners, guiding the reader from the style of quantum mechanical thinking to that of QFT, and distilling the key ideas without a welter of unnecessary detail. In contrast with standard texts, which are predominantly particle physics-centric, this book is designed to be "subfield-neutral" - usable by students of any background and interest, and easily adaptable in a course setting according to instructors' preferences. The authors' conviction is that QFT is a core element of physics that should be understood by all PhD physicists-but that developing an appreciation for it does not require digesting a large, encyclopedic volume"--

“For too long the Left has tried to silence the Right through a war on words. Understanding their tactics and what we can do about it is crucial. Sam Sorbo lays it all out.” — Sean Spicer, Host of Spicer&Co In Words for Warriors, with her trademark wit and intelligence, Sam Sorbo shows exactly how radical left-wingers have manipulated language to fit their own socialistic and anti-freedom agenda. Sam Sorbo is on a mission to reclaim today’s hot button/culture war words for all freedom-loving Americans. After hearing all the hatred spewing from ideologues, mainstream media, social justice warriors, and political hacks, Sam Sorbo was fed up: “I’m tired of their games, so I’m calling BS on them. It’s time to set the record straight, especially for the folks who are just trying to enjoy the lives the Lord gave them and want a few things explained in easy-to-understand prose.” Arranged in an accessible “A-Z” glossary style, readers can dip in to discover the real meanings behind the acronyms, words, and phrases that the toxic liberal left loves to force on the rest of us. From Ad hominem, antifa, and anarchy… To woke, wonk, and zeitgeist Mixed with the newly-coined concepts like covidiot, pizzagate, and TERF… Words for Warriors is a treasure trove of linguistic gymnastics the Democrats and other toxic lefties employ to further their anti-American agenda. Arm yourself with Words for Warriors, and fight back against political correctness that squashes real debate, free speech, and prosperity.

Marriage, Movies, and Miracles. Oh, my! Marriage is a dance (even when you step on each other's toes), and movies are minefields of problems and politics, but miracles are more common than you might believe. Kevin and Sam show that if you keep your feet moving and your hearts focused on God's divine rhythm, you can discover successes you might never imagine. All it takes is a little faith. On Television and in film, Kevin has portrayed demi-gods and evil professors, while in his private life, he's battled his fair share of demons - the three strokes that left him nearly paralyzed and still partially blind. He credits his wife's "tough love" encouragement; nauseating, relentless optimism; and tireless, constant nagging for pulling him through some of the worst episodes in his recovery. Getting married to a fundamentally debilitated "Hercules" was something Sam never shied away from. In Kevin, she recognized the love of her life and determined to see him through thick and thin. The phrase goes, "for better or for worse," and Kevin often says, "She got the 'worse' part out of the way first!" Sam had confidence that Kevin would recover and thrive, and she put action to her faith. In their third year of married life, once doubt about Kevin's full recovery was laid aside, the near-newly-weds determined to build their family. That was going to be yet another trial for them to endure and conquer. They both credit their faith in God for pulling them through the tough times, and laying the foundation for their joy. That is how they came to make movies as a team. Christ said, "In this world you will have trouble. But take heart! I have overcome the world." (John 16:33) Throughout True Faith, the Sorbos personify this verse as they embrace the struggles they meet and use their faith to bolster their responses. Be uplifted and inspired as you join Sam and Kevin on a journey through trials and triumphs, a couple of faithful Christians who work together, learn together, grieve together, and live life as Christ advocates: abundantly.
