"Scientist Without A Laboratory" presents two interests of this author, one medical, the other pure science. For half a century, as a specialist in diseases of the eyes, ear, nose, and throat, he was involved with medical and surgical problems of that specialty. Upon retirement, his interests turned to physics and radioactivity. After ten years of study and discussion, He rejects the current theory that permits certain particles to become radioactive, to their own choosing, through "barrier penetration" or "tunneling." He proposes a process based in the simple law of nature that "opposite charges attract each other and similar charges repel each other." Radioactive particles are released on that basis. A simple diagram of these interactions clarifies the stages of that process.
