This
volume surveys the most significant scientific discoveries of the first
part of the twentieth century. This turbulent era, which saw two world wars, was a time of
extraordinary scientific activity. In the life science, scientists discovered the function
of DNA and began to uncover the process by which genetic traits are passed on. Powerful
new drugs conquered formerly lethal diseases. The physical sciences were rocked, first by
the discovery of radioactivity and X-rays, and latterly the development of the atom bomb.
This volume, illustrated with vivid photographs, outlines the scientific breakthroughs of
this period that gave humans tremendous power-and a tremendous
responsibility. |
