In 'The Secret of Alexander the Great,' Will Adams immerses us in a thrilling treasure hunt for the lost treasure of history's most enigmatic conqueror. When workers accidentally discover the entrance to a catacomb in Alexandria, a deadly race ensues to find the incalculable riches that accompanied Alexander in his tomb. Daniel Knox, a marginalized Egyptologist, finds himself embroiled in this dangerous adventure, pursued by a ruthless shipping magnate and facing other treasure hunters willing to do anything to achieve their goal. Can Knox survive and reveal the secret of Alexander the Great before it's too late?
The Adams–Williamson equation, named after Leason H. Adams and E. D. Williamson, is an equation used to determine density as a function of radius, more commonly used to determine the relation between the velocities of seismic waves and the density of the Earth's interior. Given the average density of rocks at the Earth's surface and profiles of the P-wave and S-wave speeds as function of depth, it can predict how density increases with depth. It assumes that the compression is adiabatic and that the Earth is spherically symmetric, homogeneous, and in hydrostatic equilibrium. It can also be applied to spherical shells with that property. It is an important part of models of the Earth's interior such as the Preliminary reference Earth model (PREM).
