The Evolution of the Geek

Rarely, if ever, do I step outside of the realm of professional and/or educational resources when blogging on MikeStratton.net. That said, I feel that this blog is highly relevant as most believe that computer guys, those that work in the field of Information Technology and Software, are geeks.

The evolution of the geek has been great, indeed. As far as today’s standards are concerned, being a geek is a great way to make a living! That is of course. if you ...

Open Systems Interconnection (OSI) Model

The Open Systems Interconnection Model

History of the Open Systems Interconnection Model

During the late 1970’s the ISO (http://www.iso.org) developed a theoretical model for networking hardware and software called the Open Systems Interconnection model. The Open Systems Interconnection model was derived, in part, from standards defined within the Advanced Research Projects Agency Network (ARPANET). The OSI model was implemented to address a need to allow multi-vendor interoperability of networking systems; for, the ARPANET was confined to the interconnection of systems within ...

The Pigeonhole Principle

The following excerpt was taken from:
Kolman, Busby, & Ross(2009), Discrete Mathematical Structures, 6th ed. Upper Saddle River, NJ: Pearson Prentice Hall

“Theorem: The Pigeonhole Principle

The Pigeonhole Principle is a proof technique that often uses discrete math’s counting methods.

If n pigeons are assigned to m pigeonholes, and m < n, then at least one pigeonhole contains two or more pigeons.

Pigeonhole Principle – Proof

Suppose each pigeonhole contains at most 1 pigeon. Then at most m pigeons have been assigned. But since m ...

Fundamentals of Discrete Math

Fundamentals of Discrete Mathematical Structures

This post contains a synopsis of the fundamentals of discrete mathematical structures. This post was created during my second year of college while studying to attain a Bachelors of Science in Computer Science.  The discrete math course is a necessary requirement in attaining a B.S. in Computer Science.

“The origins of matrices goes back to approximately 200 B.C.E, when they were used by the Chinese to solve linear systems of equations” (Kolman, Busby, & Ross, 2009).

Six Trigonometric Functions in Terms of Others

Trigonometric Identities

“In mathematics, the trigonometric functions (also called circular functions) are functions of an angle. They are used to relate the angles of a triangle to the lengths of the sides of a triangle. Trigonometric functions are important in the study of triangles and modeling periodic phenomena, among many other applications.

The most familiar trigonometric functions are the sine, cosine, and tangent. In the context of the standard unit circle with radius 1, where a triangle is formed by a ...
