Rhodes's job is to read such documents, catalog them, and make them available to historians, journalists, and the curious. The paper was crisp, like new. Rhodes began to read. He soon realized that the file box contained highly unusual material. Inside the box was a trove of oddities: cutaway schematics of disc-shaped aircraft, graphs showing drag and thrust performance at more than Mach 3, black-and-white photos of Frisbee shapes in supersonic wind tunnels.

In physics , statistical mechanics is a mathematical framework that applies statistical methods and probability theory to large assemblies of microscopic entities. It does not assume or postulate any natural laws, but explains the macroscopic behavior of nature from the behavior of such ensembles. Statistical mechanics arose out of the development of classical thermodynamics , a field for which it was successful in explaining macroscopic physical properties such as temperature , pressure , heat capacity , in terms of microscopic parameters that fluctuate about average values, characterized by probability distributions. This established the field of statistical thermodynamics and statistical physics. The founding of the field of statistical mechanics is generally credited to Austrian physicist Ludwig Boltzmann , who developed the fundamental interpretation of entropy in terms of a collection of microstates, to Scottish physicist James Clerk Maxwell , who developed models of probability distribution of such states, and to American Josiah Willard Gibbs , who coined the name of the field in While classical thermodynamics is primarily concerned with thermodynamic equilibrium , statistical mechanics has been applied in non-equilibrium statistical mechanics to the issues of microscopically modeling the speed of irreversible processes that are driven by imbalances. Examples of such processes include chemical reactions or flows of particles and heat.

Engineering mechanics is the application of mechanics to solve problems involving common engineering elements. The goal of this Engineering Mechanics course is to expose students to problems in mechanics as applied to plausibly real-world scenarios. Problems of particular types are explored in detail in the hopes that students will gain an inductive understanding of the underlying principles at work; students should then be able to recognize problems of this sort in real-world situations and respond accordingly. Further, this text aims to support the learning of Engineering Mechanics with theoretical material, general key techniques, and a sufficient number of solved sample problems to satisfy the first objective as outlined above. Physics also involve optics, waves, quantum, and relativity theory, which have no fundamental engineering application yet.
In everyday use and in kinematics , the speed commonly referred to as v of an object is the magnitude of the change of its position ; it is thus a scalar quantity. Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second , but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour. For air and marine travel the knot is commonly used.
