The reader perhaps misses the term ‘ether’ which did not appear up to this moment. The omission was a deliberate one. Ether has been abandoned for the same reason as books on modern thermodynamics usually refrain from mentioning caloricum. Both ether and caloricum were important stages in the history of physics but the recognition that neither of them exists was an important step forward. In textbooks whose purpose is a concise presentation of physics in its contemporary state there remains no place for either of them. At the same time it is certainly true that familiarity with their role in the formation of science is instrumental in the fuller appreciation of the concepts of modern physics.
