Modeling Projectile Motion Using Python

Any system or process can be described by some mathematical equations. Their nature may be arbitrary. Does security service of a stadium want to know fan traffic in the case of fire? Does an engineer construct a thermal generating unit for your house? Usually, using a small set of general rules and laws of nature, one can predict everything at least for the nearest future. So, in this article, we’ll continue our topic of the computer simulations and deal with the way all these calculations are performed. (more…)

The Secret of Perfect Numbers

Numbers accompany us from birth until the last days and we can’t imagine the life without them. Among all the numbers, there are some special ones, named perfect. And despite a lot of papers are devoted to these perfect numbers, only 24 such numbers have been determined so far. So what is special about these numbers? Well, the number is called perfect if it is equal to the sum of all its proper divisors excluding itself. Now, let’s find out more! (more…)

Kirchhoff’s Circuit Law and Circuit Analysis

When we deal with the complex electric circuits (like T-circuits), we use some mathematical techniques to find the current and voltage drops in the circuit. It’s not as difficult as it may seem at the first sight. In this post, we will tell you how to analyze the circuit with the help of the Kirchhoff’s Circuit Law. (more…)

Finding Square Root Without a Calculator

All of us widely use calculators to perform mathematical operations. Obviously, these machines were invented by people, who determined their work according to the certain algorithms for quick count. In this article, we’re going to tell you about one of such algorithms. We’ll also show how you can extract square roots in column and you’ll see that the result of this operation can be received with arbitrary precision; we can find any digits number in its decimal representation, even if it turns irrational.

Price Elasticity of Demand and Supply

Price elasticity is a very important notion in economics, which, however, is not always recognized by students. Let’s imagine that certain firm increases the prices for its products. Many of us may suppose that in this case, the firm has an opportunity to increase the total revenue from the sale of products. But in fact, it doesn’t. It is even possible, that increase in price will lead to the decrease in total revenue because the demand on firm’s product also decreases. That’s why the price elasticity has the great significance for producer of goods and we’re going to tell you how it works in this article. (more…)
