The second option was by far the most popular for at least three reasons: it implied a more familiar kind of elasticity; it bore the stamp of Fresnel’s authority; it permitted a simple interpretation of the Fresnel drag, as we will see in a moment.

The AdS 3/CFT2 correspondence in black hole physics

... The subject of black holes has been around for almost a century in different manifestations. Their status has fluctuated over the years, from being viewed as singular solutions of the Einstein equations to becoming a major branch of research in classical General Relativity. This led to a ‘golden age ...

Introduction to Classical Field Theory
