I have felt through the years that even though I didn't get much of an education and that I was raised hard with only the bare necessities being met; I didn't have to turn bad by learning to rob, cheat, and steal to get what I wanted out of life. Instead of following the path to destruction, I worked at making myself a smarter, better person so I could support my family well enough and not consider myself poor. Being poor isn't wrong, it was just that I didn't want to be poor, not anymore. It has taken me over ninety years to get to this day. Some of the years were hard and I really wouldn't like to live through them again, but many years were good and well worth repeating. I have traveled through the years of extreme poverty to a point in my life when I was worth a million plus dollars. That isn't the case right now, but it might be again. 90 Years and Still Going Strong is my story of the good years and the bad years. I hope you enjoy reading about my life as much as I have enjoyed living it.

My journey is documented in this two-volume book numbers 14th and 15th of my series “Christianity and the Human Brain”. My journey is a testimony to Lord Jesus who took me by the hand from being a dismal soul to a renown neurosurgeon and anesthesiologist through a dream I had in 1974 with his words: “Son study all these books in my hand and I shall bless you and bless your patients”. Today, 35 years later, I continue to dedicate my life to my Lord, my patients and the residents I mentor. The fulfillment of my joy is when my Almighty helps me to care for my patients and guides my hand in both neurosurgery and the teaching of coming generations. There are many stories and reflections to share with you. Lessons learned in various topics. It is my honor to share with you my journey and my Joy. The two volume books contain 181 chapters, distributed in twenty sections (ten in each volume) covering major highlights in my life journey. In addition to deep reflections from my own life stories in faith and medicine, topics include Jesus, love, patient care, the human brain, neurosurgery, illness, residents, healthcare crises, meditations and memories over four decades. I hope you, the reader, to take the positives of my journey and find it useful to your own journey as a participant sojourning in this world with me. Blessed are those striving early on in their life to serve our Savior Jesus Christ, to him is the glory for ever and ever, Amen.

This textbook covers a broad spectrum of developments in QFT, emphasizing those aspects that are now well consolidated and for which satisfactory theoretical descriptions have been provided. The book is unique in that it offers a new approach to the subject and explores many topics merely touched upon, if covered at all, in standard reference works. A detailed and largely non-technical introductory chapter traces the development of QFT from its inception in 1926. The elegant functional differential approach put forward by Schwinger, referred to as the quantum dynamical (action) principle, and its underlying theory are used systematically in order to generate the so-called vacuum-to-vacuum transition amplitude of both abelian and non-abelian gauge theories, in addition to Feynman’s well-known functional integral approach, referred to as the path-integral approach. Given the wealth of information also to be found in the abelian case, equal importance is put on both abelian and non-abelian gauge theories. Particular emphasis is placed on the concept of a quantum field and its particle content to provide an appropriate description of physical processes at high energies, where relativity becomes indispensable. Moreover, quantum mechanics implies that a wave function renormalization arises in the QFT field independent of any perturbation theory - a point not sufficiently emphasized in the literature. The book provides an overview of all the fields encountered in present high-energy physics, together with the details of the underlying derivations. Further, it presents “deep inelastic” experiments as a fundamental application of quantum chromodynamics. Though the author makes a point of deriving points in detail, the book still requires good background knowledge of quantum mechanics, including the Dirac Theory, as well as elements of the Klein-Gordon equation. The present volume sets the language, the notation and provides additional background for reading Quantum Field Theory II - Introduction to Quantum Gravity, Supersymmetry and String Theory, by the same author. Students in this field might benefit from first reading the book Quantum Theory: A Wide Spectrum (Springer, 2006), by the same author.
