Discusses the scientific research which led to the current theories of the speed of light, from classical ideas and the challenges of the Middle Ages to new theories and modern measurements.

If you are looking for a top-rated science textbook, this is not the book for you. If you are looking for a reiteration of the historical progression of the physical sciences by a well-educated, experienced scientist, this book's not for you. However, if you are interested in considering logical thinking that is outside the scientific box and that challenges conventional science concepts, this may be the book for you.The entire first section presents a logical, convincing argument that concludes that the problem Einstein solved with his special theory of relativity never existed in the first place. There is nothing wrong with his reasoning or mathematical equations that address the problem he believed existed. There just was not a real problem to begin with. The whole section is an excellent tutorial on Einstein and relativity for anyone who is interested in understanding relativity, whether the reader agrees or disagrees with the conclusions.The second section is a tutorial on electrons and their role in the production of light, the reflection and refraction of light, and the role of electrons in the production of electricity, electronic device function, and heat. All tutorials are written in laymen's easy-to-read language.The third section examines many outside-the-box hypotheses in the realm of theoretical physics. This book is packed with easy-to-read nonmathematical explanations of physical phenomena, ranging from the appearance and properties of electrons to the construction of matter from particles and energy fields. Have you ever wondered what charge is or why electrons do not fly apart from internal repulsive forces or spiral into the nucleus of atoms? Is light a continuous wave or pulses of electromagnetic field? Why do moving electromagnetic fields not have positive and negative charge or north and south poles? How does light reflect off itself? Why is your car battery attached to the body of the car? How do atoms attract to form molecules when their electrons repel one another? These and other questions are answered, often in unconventional ways, but others may not be answered at all. If you need a science research project or a dissertation idea, this book is for you. If you do not need it for a project but you just have an interest in better understanding science, this book is for you. If you have an open mind enough to at least consider alternate ways of thinking about scientific concepts and principles, this book is definitely for you.

The fundamental principles of the scientific method are essential for enhancing perspective, increasing productivity, and stimulating innovation. These principles include deductive and inductive logic, probability, parsimony and hypothesis testing, as well as science's presuppositions, limitations, ethics and bold claims of rationality and truth. The examples and case studies drawn upon in this book span the physical, biological and social sciences; include applications in agriculture, engineering and medicine; and also explore science's interrelationships with disciplines in the humanities such as philosophy and law. Informed by position papers on science from the American Association for the Advancement of Science, National Academy of Sciences and National Science Foundation, this book aligns with a distinctively mainstream vision of science. It is an ideal resource for anyone undertaking a systematic study of scientific method for the first time, from undergraduates to professionals in both the sciences and the humanities.
