## Irrational numbers

Published December 11, 2016

Irrational numbers were discovered in the Pythagorean school when trying to measure the diagonal of a square with its side. The Pythagoreans attributed the numbers to the divine power, and the Pythagorean system of knowledge consisted of four sections: arithmetic (the science of numbers), geometry (the doctrine of figures and their measurement), music...

## Deterministic and nondeterministic systems

Published February 12, 2017

Mathematics helps system technicians to give advice to specialists, working every time in a new field. It makes it possible to isolate the general from the private, to create a mathematical model of the process and, after analyzing it, to give recommendations on the reorganization of production. This was accomplished by breaking all existing systems into two large classes-deterministic and nondeterministic systems...

## Fractional numbers

Published December 11, 2016

With the emergence of representations of integers, there were representations of parts of the whole subject. With the advent of natural number n, there was the concept of fractional numbers of the form 1/n. Historically fractional numbers occurred during the measurement. Fractions naturally arises in the solution of problems on the division of property, land measuring, calculating time...

## Normal weight

Published February 12, 2017

If we assume that all human bodies are geometrically similar (this is true only on average), it is possible to calculate the normal weight people for their growth. The average height is 1.75 meters, and the average weight - 65 kilograms. Resulting in these calculations results may seem surprising to many...

## Systematic approach

Published April 19, 2017

We often hear that a systematic approach is needed to perform a task. But, what is this in terms of mathematics? First, let's look at some examples of using the systematic approach. What the weather will be tomorrow? To answer this question, thousands of people work and even more devices. The information of local weather stations, sometimes located in the most remote corners of the country...

## What is triangulation?

Published November 26, 2017

The art of surveyors is to determine distances and corners, not accessible to direct measurement. Measuring distances with a measured baton or measuring tape is not an easy task, it is much easier to measure angles with a theodolite. This will help triangulation. Let's see what it is...
