Does Homework Help or Harm?

We bet at least once you dreamt about moving to a kind of wonderland where students don’t have to do their homework every day. It may sound unreal, but such fairytale countries where kids spend only a couple of hours per week on homework exist. They had gone through a long way of trial and errors before realized all pros and cons of homework and introduced innovative changes into their system of education. However, why does the necessity of homework remain a topic for a debate, where the opposite side stands for giving as many home assignments to students as possible? It, therefore, sparks a question whether homework is actually harmful or helpful. (more…)

Circuit Analysis using the Node Voltage Method

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…)

How to Memorize English Words

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…)

Common Errors in Calculus Exercises

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…)

Mesh Current Method and Its Application

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…)

How to Get 100 With Nine Different Figures

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…)

How to Improve Your English If You Are Super Busy

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…)
