What instruments did they devise to measure the Earth-related phenomena they were interested in? This Memoir attempts to answer such questions in a well-illustrated, and largely non-technical, account. The seventeenth century saw magnetism used as an aid to prospecting for iron ore in Sweden, and Isaac Newton’s derivation of the law of gravitational attraction. A gradually increasing interest in ‘physics of the Earth’ brought forth the new discipline of ‘geophysics’ in the early nineteenth century and, by the end of the following century, airborne and satellite-based investigations had become routine. The Emergence of Geophysics explores this evolution in several parallel strands: terrestrial magnetism and electricity, gravity, seismicity, heat, geodynamics and radioactivity, broadly reflecting the timing of their introduction as tools aiding geophysical studies. Biographical information is included for many of its practitioners and the book should be of interest to both geophysicists and to anyone interested in the history of Earth science.
