• ## Media Equation

1035 Words  | 3 Pages

The media equation is a theory developed by two professors of communication, Byron Reeves and Clifford Nass, at Stanford University. The theory is simple. They state that people treat the media as if they were real, hence the equation: media = real life. Basically Reeves and Nass are saying that people on an unconscious level perceive the media as real. People view objects of the media are talking to them personally. Reeves and Nass view things such as computers, televisions, radios, and other media’s

• ## Cubic Equations

531 Words  | 2 Pages

Cubic equations were known since ancient times, even from the Babylonians. However they did not know how to solve all cubic equations. There are many mathematicians that attempted to solve this “impossible equation”. Scipione del Ferro in the 16th century, made progress on the cubic by figuring out how to solve a 3rd degree equation that lacks a 2nd degree. He passes the solution onto his student, Fiore, right on his deathbed. In 1535 Niccolò Tartaglia figures out how to solve x3+px2=q and later

Five Equations That Changed The World “He [Isaac Newton] sought out secluded areas, where he would sit for hours at a time, not so much to observe the natural world as to immerse himself in it” Sir Isaac Newton was a man who would keep to himself. If not for that quality he may not have made the discoveries that he did. He would often sit in the garden for hours on end just thinking and formulating his ideas about the universe. In fact, that is the very place where the ideas of gravity and

• ## Differential Equations

2562 Words  | 6 Pages

Approximating Solutions for Differential Equations A differential equation is defined as an equation which relates an unknown function to one or more derivatives. When solved and transformed into its original equation in the form f(x), an exact value can be found at any given point. While some differential equations can be solved, it is important to realize that very few differential equations that come from "real world" problems can be solved explicitly, and often it is necessary to resort to numerical

• ## The Quartic Equation and Lodovico Ferrari

1484 Words  | 3 Pages

The quartic equation is used by geometry teachers around the world and in computer graphics. This formula originated in Italy in the 1500’s. It was rare for someone to find a solution and achieve fame in doing so. The chances of that happening were slim to none due to the lack of education during this period. A mathematician named Lodovico Ferrari beat those odds and created a formula that still has applications today. Italy in the 1500’s was a different place than what people know now. They had

• ## What Is Partial Differential Equation

3084 Words  | 7 Pages

ABSTRACT A partial differential equation is a differential equation that contain unknown multivariable functions and their partial derivatives while ordinary differential equations contains function of a single variables and their derivatives. Therefore, an ordinary differential equation is a special case of partial differential equation but the behaviour of a solution is quite different. It is much more complicated in the case of partial differential equation because it has more than one independent
