Humanity has always wished to make the life easier. Initially, people invented the abacus (primitive counting board) for easy calculations, then there was a calculator, next appeared some huge calculating machines and finally have come the computers. Now, almost any gadget has a calculator and all the complex calculations are performed with the help of the built-in functions of the textual and spreadsheet editors. (more…)
You’re almost in the middle of your studying year, but you still can’t concentrate on your homework. And you know perfectly well that if you don’t, chances are you may fail.

Yes, there is and we’re going to help you with that. (more…)
Recently, the term “catastrophe” started to appear not only in the newspaper articles and TV news but also in… mathematics! The first signs of the catastrophe theory emerged in the early 70s and provoked a revolution in mathematics. This achievement is only comparable to the invention of integral and differential calculus. While Newton’s theory allows investigating smooth, continuous processes, catastrophe theory provides a universal “recipe” for the study of abrupt transitions, ruptures and sudden qualitative changes.

Today, we clearly understand that the assimilated sources of energy (coal, oil, gas, for example) will soon be depleted. The nuclear power stations can provide us with energy for hundreds of years, but they have a serious disadvantage – a huge amount of radioactive waste with a long half-life that remains during its work. That’s why we try to find the alternative sources of energy and the most promising of them is the controlled thermonuclear fusion. (more…)
Most high school students are afraid of math lessons wondering whether they can ever use the acquired knowledge in the real life. Today, when so many calculations are carried out by computers, algebra and geometry find good realization in 3D graphics industry. And if you still don’t know how why math is so useful for 3D graphics, this article is for you. (more…)
When you get too complicated homework, who do you blame? When you fail a test who is the first person you get mad at?
