Great Ideas for Math, Graph Theory – Science – Life

Beginning with the Sunday tour of the wealthy classes in the thirteenth century across seven bridges over the River Briegel—which divided the ancient city of Königsberg in East Prussia (present-day Kaliningrad in Russia) into four sectors—no section repeated, but this, effectively, allowed him to cross With every bridge and pedestrian taking to the point of origin, one of the most timeless educational theories in mathematics arose, the graph theorems.

The graph raised by the Swiss Leonhard Paul Euler, circa 1700, is nothing more than a mathematical formulation of a problem in everyday life without recourse to algebraic, numerical or geometric relations, but rather to graphs, avoiding falling into Design thinking (Think about the pictures.)

Although popular in the business world, the way they invite you to think in pictures depends on the peculiarities of the objects that make up a system (height, shape, size, etc.) and not on what the genius of modern mathematical notation has already discovered (he generalized f(x) to denote function f in the argument x and the Greek letter for connecting the lengths of diameter and circumference, among others), which were the interconnections between these parts; Hence the need to avoid confusion.

“In the problem of Königsberg bridges, we are indifferent to the size, length and direction of the bridges or the distance between them. The important thing in this case is to make an abstraction and to move from the physical map with bridges, river and land masses, to a set of points and lines connecting them,” writes Javier Galeano and Juan Gabriel Pasteur, authors of the new rendition of great mathematics ideas.

In this volume 17 of the collection we find a comprehensive and practical explanation of types of graphs (or networks) and their applications in everyday life, from the Internet model itself, through the country’s electrical distribution networks, neural intersections, also travel through natural ecosystems, and the spread of epidemics (including including zombie apocalypse) and access to examples of the most intertwined networks in the modern world: social networks.
