10 equations that have changed the world and our lives

Zak Ben - Monday, April 07, 2014
What are the mathematical equations that we will never forget for the influence they have had on the world and our own lives? Here they are!


10. Pythagorean Theorem



We start from the famous Pythagorean Theorem, that all of you will surely studied in school: it is the fundamental theorem of geometry, and describes the relationship between the sides of a right triangle! With it, you can distinguish from the non-Euclidean geometry Euclidean, for which this theorem is not true!


9. Newton's law of universal gravitation


Newton was the first to discover the existence of gravity, a force absolutely fundamental to our life! It was the fall of an apple to allow him to notice this: such force keeps the planets in orbit around the Sun, and the Moon around the Earth!

8. Euler's formula for polyhedra


Can not forget the Euler: it was he, with his formula for polyhedra, to say that the sum of the vertices of the angles less than the number of faces in each polyhedron, is constant! Thanks to it, you have begun to develop the topology!

7. Wave equation


Have you ever wondered what are the physical laws describing the motion of the waves?!? Here they are: the wave equation were developed by d'Alembert, and it is hyperbolic partial differential equation of great importance! It includes several fields of physics: acoustics, fluid dynamics and electromagnetism.

6. Maxwell's equations


Maxweel was a great Scottish mathematician and physicist, who worked to develop a system of linear partial differential equations and coupled, which describe the electromagnetic interaction, together with the law of force. The electromagnetic field is subject to various constraints and temporal evolution, and these equations prove it!

5. Second law of thermodynamics


The Second Law of Thermodynamics states that the entropy of an isolated system far from equilibrium terminology tends to rise over time, until it reaches equilibrium. For the uninitiated, the entropy measure what is the disorder of the system!

4. Theory of Black-Scholes


Developed by Fisher Black and Myron Scholes, the equation that led to calculate the value of financial products, especially useful to professionals in finance, marked the world: the evaluation of a contract, according to this theory, depends solely and exclusively by the terms of the contract and the volatility of the underlying security.

3. Shannon theory


Do you know what a bit? This is the minimum unit of information: this word was coined by its Shannon, when in 1948 he published the essay "A mathematical theory of communication," in which those who have rebuilt the information transmitted by a sender using causal analysis and large deviations.

2. Chaos Theory


Never heard of this theory?!? Chaos Theory describes a process that evolves over time, which depends on the initial conditions: as a result, even the smallest change can make the beginning of substantial differences in the evolution of the system! This theory is applied both to the medicine, that finance, and other fields.

1. General Relativity


It would have been impossible not to give priority to the Theory of Relativity of Einstein's great! Taking advantage of the work of differential geometry of Italian Luigi Bianchi, Gregorio Ricci-Curbastro and Tullio Levi-Civita, the renowned physicist was able to describe the gravitational interaction as a result of a physical law that binds destruction and flow of mass in space-time, energy and momentum with the geometry of space-time itself!
