From That to This

13.8 billion years ago, the Big Bang began the conception of life in the universe. 9.2 billion years after that, the first thermonuclear fusion in the heart of our sun was the birth of humanity itself. From That to This is a journey through the evolution of elements, from the simple element of hydrogen to the last man-made element in the periodic table, oganesson. However, the whole spectrum of electromagnetic radiations has been practically unchanged since the Big Bang. As a matter of fact, the cosmic microwave background radiations from the time of the Big Bang still linger around the whole universe. From these radiations, astrophysicists can measure and calculate the authenticity of the Big Bang theory. This book will take you through the creation of the atom bomb and its unimaginable destructive power. It will pass through the end of WWII, the time in which scientists came to their senses and dedicated the atomic industry to humanitarian efforts-?such as lighting up thousands of cities and saving millions of lives in the medical field. In the final chapter, there is an emphasis on some of the procedures done in departments of nuclear medicine in order to familiarize college students, the public, and patients who may need some clarification on these matters.
