+ EM GeoSci is an open-source resource that emphasizes the physical principles

59

60

65

66
+ `Case Histories <https://em.geosci.xyz/content/case_histories/index.html#case-histories-index >`_
67
+ play an essential role. They allow readers to make the
68
+ connection between the geoscience problem, the EM survey, and the eventual
69
+ outcome. Understanding the fundamental physics is facilitated through the use
70
+ of `Jupyter Notebooks <https://mybinder.org/v2/gh/geoscixyz/em-apps/master?filepath=index.ipynb >`_
71
+ which allow users to visualize fields and
72

73

74
+ Estimation in Geophysics).
