In this article, we will tell you about one more method of circuit analysis, which is called the Node Voltage Method. It also allows to reduce the calculations and save the time when we do the circuit analysis. Let’s firstly consider the T-circuit scheme from our previous post and solve it with the help of the Node Voltage Method. (more…)
Is that possible to learn the language completely? Just any language, native or foreign in, say, 10, 25, 70 years? No. And to master English, it is of major importance to always refresh language structures, update your idiomatic base, modernize grammar, immerse into English speaking environment and add new lexical units to your word stock. Here we’re going to speak about the latter and, believe, it doesn’t come as a problem when you know some useful tips. (more…)
Practical exercises make an important part of a math course, which helps to deeper understand all theoretical information and further study more complex math sections. Quite often students do not even realize that they make mistakes and why that happens. In this article, we will analyze the most common student’s problems met while solving calculus homework. (more…)
Previously, we’ve already introduced the Kirchhoff’s Circuit Law as a separate topic. And today, we shall consider another method for the circuit analysis, which is called the Mesh Current Method. The advantage of this method is that we obtain less unknown variables and equations when we solve the circuit. Let’s consider the T-circuit scheme from the mentioned post and solve it with the help of the Mesh Current Method. (more…)
There are a lot of different math tricks that can impress you with their beauty and compactness. In this post, you will find not only their examples but also will try to create your own. To begin with, a few “Mathematical Curiosities” are introduced by the famous Russian mathematician and physicist Yakov Perelman (1882-1942) in his popular book “Arithmetic for entertainment”. Here are some of them: (more…)
Scientists all over the world usually argue about when it is better to learn a language. And we argue with them that there is no better time than NOW. No matter what county you live in, what age you are and what specialization you have, “I have no time” and “I was badly taught at school” are no longer the excuses. Actually, everybody has no time, but for many it’s not a problem. Surprized? Let’s then find out how to cope with this. (more…)
For a student, there’s nothing more pleasing than planning a summer vacation, especially when summer is in full swing. But how many of you have ever made up some colossal plans and finally failed with more than half points in the list? Even this year? Well, a lot. And we are not trying to judge or demotivate you to arrange your future free time, let’s just together take a look at how to make the most of the rest of your summer. (more…)
