His brother did not fall from the tower tied off to a piece of steel and was not cut in two. “That is not so,” he said. The workers were not tied to the structure while working, Barnard said. He did see his brother fall, but he was not cut in two.

REBOUND (github.com/hannorein/rebound) REBOUND is an N-body integrator, i.e. a software package that can integrate the motion of particles under the influence of gravity. The particles can represent stars, planets, moons, ring or dust particles. REBOUND is very flexible and can be customized to accurately and efficiently solve many problems in astrophysics.

There are metaphysical problems, which cannot be disposed of by declaring them meaningless. For, as I have repeatedly said, they are “beyond physics” indeed and demand an act of faith. We have to accept this fact to be honest. There are two objectionable types of believers: those who believe the incredible and those who believe that “belief” must be discarded and replaced by “the scientific method.” Max Born, Natural Philosophy of Cause and Chance (1964)
Maxwell’s equations… originally consisted of eight equations. These equations are not “beautiful.” They do not possess much symmetry. In their original form, they are ugly. …However, when rewritten using time as the fourth dimension, this rather awkward set of eight equations collapses into a single tensor equation. This is what a physicist calls “beauty,” because both criteria are now satisfied.

wikipedia

Physics (Wikipedia) Physics is the natural science of matter, involving the study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. A scientist who specializes in the field of physics is called a physicist.
