  The atomic bomb uses fission of heavy elements to produce a large amount of
energy. It was designed and deployed during World War II by the United States
military. The first test of an atomic bomb occurred in July of 1945 in New
Mexico and was given the name Trinity; this test was not declassified until
1949. In that year Geoffrey Ingram Taylor released two papers, detailing his
process in calculating the energy yield of the atomic bomb from pictures of the
Trinity explosion alone. Many scientists made similar calculations
concurrently, though Taylor is often accredited with them. Since then many
scientists have also attempted a to calculate a yield through various methods.
This paper walks through these methods with a focus on Taylor's method -- based
on first principles -- as well as redoing the calculations that he performed
with modern tools. In this paper we make use of the state-of-the-art computer
vision tools to find a more precise measurement of the blast radius, as well as
using curve fitting and numerical integration methods. With more precise
measurements we are able to follow in Taylor's footstep towards a more accurate
approximation.
