This marvelous book provides unique insights into the state of physics ca. 1904. The year 1904 marks the middle of a period during which physics underwent a major revolution, comparable to the one engendered by Newton -- or the current revolution in DNA/microbiology. Beginning with Konrad Roentgen's 1895 discovery of x-rays, came an unprecedented streak of discoveries: Becquerel's discovery of radioactivity in uranium ores (1896); J. J. Thomson discovery of the electron (1897); radioactivity of thorium (1898); Curies identify radium and polonium and coin the term "radioactivity" (1898). In the years following additional discoveries continued to pour in, so that by the nineteen-thirties a fairly clear and consistent picture of the atom and its nucleus had emerged.The amount of knowledge, understanding, and intelligent conjectures contained in this book is truly amazing -- considering that only eight years had elapses since the discovery of radioactivity. For example: alpha, beta, and gamma rays had been identified, and it was recognized that radioactivity transmuted one element into another -- something considered impossible before. Also of great interest is that in 1904 there were already clues that the mass of a particle increases as the speed of light is approached - and this was at least a year before Einstein's celebrated paper. All this is clearly presented in this book.
Areas which posed special difficulties to the early pioneers deserve special attention. For example: expecting to find positively charged particles similar in charge-to mass ratio as the electron, the early pioneers failed to recognize the hydrogen nucleus as the basic positive particle (i.e., the proton). (The positron, analogous to the electron, is a rare particle, discovered only much later.) They also had difficulty with why the atomic weights were not always integral multiples of hydrogen. (Thus, chlorine is 37.5, or halfway between two multiples of hydrogen. The element tellurium has a greater atomic weight than iodine, even though it tellurium precedes iodine in the periodic table.) The answer to the riddle, of course, lies with the neutron, and the existence of isotopes. However, the concept of a neutral particle did not come easy, and so it took a number of years to resolve these issues.
The style of the book is somewhat along the lines of Scientific American, in that concepts are clearly presented, while math is kept to a minimum. The book is a photocopy of the 1904 editions. Though a small amount of blurring is discernible, it is still fairly easy to read. Since there are no copyrights the cost of the book is kept quite low.
