Planck's Columbia lectures

The original quantum radiation theory as described by the world's greatest scientific theorist. Original unabridged translation provided, in addition to a slightly abridged version for easier reading. This book is a treatise on scientific investigation and methodology. Science teachers will find this book a rich source of material, and students will be able to understand quantum theory and relate it to the real world. Planck derived several of the laws of chemistry and physics using just 6 main equations! He said that mathematical analysis must be balanced with the reality of physical measurement, going so far as to say that purely abstract theories are "dangerous". A classic science book for all time.
