@jeeperman, Wrong again, that is not a pressurized trailer with an inert gas. It is a cryogenic trailer full of nitrous oxide

Notice the trailer?
An Airgas pressurized tanker.
Just imagine that truck rolling over and getting the tank punctured.
Even if it is an inert product, the pressure being released could be………………
really bad.

Geometric analysis is a mathematical discipline at the interface of differential geometry and differential equations. It includes both the use of geometrical methods in the study of partial differential equations (when it is also known as “geometric PDE”), and the application of the theory of partial differential equations to geometry. It incorporates problems involving curves and surfaces, or domains with curved boundaries, but also the study of Riemannian manifolds in arbitrary dimension. The calculus of variations is sometimes regarded as part of geometric analysis, because differential equations arising from variational principles have a strong geometric content. Geometric analysis also includes global analysis, which concerns the study of differential equations on manifolds, and the relationship between differential equations and topology.

In Layman terms, “Yep ya’ll are right, A semi might and did turn over on that curve and might again.
