'Engineering Equations' or “Engineers and Equations” is a better love story than twilight. Although we whine about being victimized by the half a million equations we have to go through in our degrees, the truth is that equations help us understand the world through the unbiased eyes of numbers and formulas. All the great scientists used this irrefutable tool to redescribe the Universe for us. From Newton’s Laws of Motion to the recent proof of Einstein’s Gravity Wave theory, it has been an incredible journey to follow these great minds in a quest to have a better understanding of how nature works and the ways it proposes anomalies that are a challenge for us.The biggest minds in the history have used mathematics to lay the foundation for how we measure and understand our universe. Time and time again, we have proved that it only takes one simple formula to alter the course of humanity. Here are ten equations that did just that :

Maxwell's equations are a set of partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits. For more details, click here.Engineering Equations 2: Theory Of Relativity
The
theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to elementary particles and their interactions, describing all their physical phenomena except gravity. General relativity explains the law of gravitation and its relation to other forces of nature. It applies to the cosmological and astrophysical realm, including astronomy.

Engineering Equations 3: Second Law of Thermodynamics
The second law of thermodynamics states that the total entropy of an isolated system can only increase over time. It can remain constant in ideal cases where the system is in a steady state (equilibrium) or undergoing a reversible process. The increase in entropy accounts for the irreversibility of natural processes, and the asymmetry between future and past. For more details, click here.Engineering Equations 4: Pythagorean Theorem
It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. The theorem can be written as an equation relating the lengths of the sides a, b
and 
c, often called the 'Pythagorean equation'. For more details, click h ere.Engineering Equations 5: Universal Law of Gravitation
Newton's law of universal gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

In quantum mechanics, the Schrödinger equation is a mathematical equation that describes the changes over time of a physical system in which quantum effects, such as wave–particle duality, are significant. The equation is a mathematical formulation for studying quantum mechanical systems. For more details, click here.Engineering Equations 7: Chaos Theory
Chaos theory is a branch of mathematics focused on the behavior of dynamical systems that are highly sensitive to initial conditions. 'Chaos' is an interdisciplinary theory stating that within the apparent randomness of chaotic complex systems, there are underlying patterns, constant feedback loops, repetition, self-similarity, fractals, self-organization, and reliance on programming at the initial point known as sensitive dependence on initial conditions.

Engineering Equations 9: Calculus
In mathematics, differential calculus is a subfield of calculus concerned with the study of the rates at which quantities change. It is one of the two traditional divisions of calculus, the other being integral calculus. For more details, click here.Engineering Equations 10: Logarithms

logarithm is the inverse operation to exponentiation. That means the logarithm of a number is the exponent to which another fixed number, the base, must be raised to produce that number. In simple cases the logarithm counts factors in multiplication. For more details, click here.Read Other Interesting Articles from Engineer's Corner Section Here
Engineering Equation Solver (EES) is a commercial software package used for solution of systems of simultaneous non-linear equations. It provides many useful specialized functions and equations for the solution of thermodynamics and heat transfer problems, making it a useful and widely used program for mechanical engineers working in these fields. EES stores thermodynamic properties, which eliminates iterative problem solving by hand through the use of code that calls properties at the specified thermodynamic properties. EES performs the iterative solving, eliminating the tedious and time-consuming task of acquiring thermodynamic properties with its built-in functions.
EES also includes parametric tables that allow the user to compare a number of variables at a time. Parametric tables can also be used to generate plots. EES can also integrate, both as a command in code and in tables. EES also provides optimization tools that minimize or maximize a chosen variable by varying a number of other variables. Lookup tables can be created to store information that can be accessed by a call in the code. EES code allows the user to input equations in any order and obtain a solution, but also can contain if-then statements, which can also be nested within each other to create if-then-else statements. Users can write functions for use in their code, and also procedures, which are functions with multiple outputs.
Adjusting the preferences allows the user choose a unit system, specify stop criteria, including the number of iterations, and also enable/disable unit checking and recommending units, among other options. Users can also specify guess values and variable limits to aid the iterative solving process and help EES quickly and successfully find a solution.
The program is developed by F-Chart Software, a commercial spin-off of Prof Sanford A Klein from Department of Mechanical EngineeringUniversity of Wisconsin-Madison.

EES is included as attached software for a number of undergraduate thermodynamics, heat-transfer and fluid mechanics textbooks from McGraw-Hill.
It integrates closely with the dynamic system simulation package TRNSYS, by some of the same authors.
