TEN EQUATIONS THAT CHANGED THE WIRLD The brightest minds in 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. ISSAC NEWTON’S LAW OF UNIVERSAL GRAVITATION Newton’s law explains why planets move the way they do‚ and how gravity works‚ both on earth and throughout the universe. First published in the

Linear Programming in Finance‚ Accounting and Economics Sijia Lu 7289928683 Abstract This article is literatures review about five articles‚ which apply linear programming to Finance‚ accounting and economics. The mathematical method is found of crucial importance in those fields. The paper shows how theoretical inference in linear programming throws light upon realistic practice‚ and how empirical evidence supports those theories. Keywords: finance; accounting; economics; linear programming; investment

In the poem “An Equation for My Children” by Wilmer Mills‚ the speaker wants to find out the relationship between his family life and mathematics. Initially‚ the speaker reveals his fascination with Pythagoras’ work‚ which inspired him to go on a quest to finding out how his family life revolved around Pythagoras’ complex theorems. Along the way‚ the speaker finds his investigation so elusive that it feels as if he asked Pythagoras himself to calculate the mathematical equation of a “music tuning

In the seventeenth century Europe‚ the study of natural sciences has changed significantly. The Renaissance · religious reform has changed the view of the world centered on God‚ and the development of the age of the great navigation brought about an overwhelming increase in knowledge information volume. The fact that the science of ancient Greece and Arabia was transmitted in the Renaissance era was one factor that advanced science. Science-based methods were incorporated into art as well.

The reason why the Drake Equation is not a successful science is because it would be impossible to calculate some of the elements in the equation. The elements would take too long to get an accurate sample to give a scientifically sound explanation. For instance how would you calculate fi (the fraction of intelligent life forms)‚ how do you define intelligent? Is intelligent like you and I‚ is it like a bird or a rat‚ could it be a plant? There is no way to truly determine what counts and doesn’t
