Magnetic and gravity methods form the cornerstone of near-surface and deep crustal imaging in modern geophysics. By measuring variations in Earth’s magnetic field and gravitational acceleration, ...

Electromagnetic (EM) methods have become pivotal in imaging the Earth’s subsurface through measurement of electrical and magnetic responses induced by natural or artificial sources. In geophysical ...

A longstanding goal in physics has been to link general relativity with quantum theory and so unify the forces of nature. Theories of quantum gravity, however, are plagued by the weak theoretical ...

Since the early days of balloon photography and military reconnaissance, people have been struck by the broad view of the Earth that the airborne perspective provides. From the first photographs of ...
