Electronics and Modern World

Let us talk today about electronics and its role in the modern world. One hundred years ago people knew not even a word. Technology was very primitive. Of course, there were such things as the internal combustion engine or the telephone... But they were simple, not as complicated as they are now. For example, a phone, a well known device for modern people, had no any electronics, it was a purely electrical device. The real power of electronics were have felt later, when the transistor was invented. Before the transistor was invented, people have used lamps. They were big, consumed a lot of power and had low mechanical strength. And, as one of the main concerns, they didn't last long. Transistors, on the other hand, were small, had consumed just a little power (compared to lamps) and were enough strong and durable enough. But progress never stops. Transistors have been getting smaller and smaller. It has led to the invention of integrated circuits - silicon wafer with millions of microscopic transistors on it. And it was a great breakthrough! Integrated circuits (or ICs) have made possible personal computers, the Internet, mobile phones and many other things. ICs gave to mankind a real power--the power of calculations. It is impossible to imagine modern world without these small black chips with a multitude of soldered pins. If people encounter a serious problem, they depend on electronics to solve it. On its precision, speed and size. And electronics easily solves almost any problem. That's why the modern world is impossible without the power of electronics.

A fantastic essay! A few notes:

Its = of it

It's = it is. [English speakers make this mistake constantly.]

I have no money = I don't have any money.

You usually meet a person, but you encounter an idea or a thing. For instance, you might encounter resistance when you try to change something.

A concept is an idea. If it actually exists outside your mind, it's a thing. A thing that you use to help you with a task is a tool (for instance, a hammer or a drill). A more complicated tool, or a mechanical or electronic one, is a device (for instance, a mobile phone or an MP3 player).
