Engineering is putting knowledge of Nature to practical use. The end result of engineering is some physical thing: a machine, a tool, a gadget. Engineering is solving problems. It’s convenient to discuss engineering projects within the framework of five steps for solving problems: define the problem, identify possible solutions, select a solution, implement the solution, verify the solution.

Alfred Nobel was a Swedish chemist who lived from 1833 to 1896. Alfred and his brother made explosives, but in 1864 there was an accident in the laboratory and Alfred’s brother was killed. Alfred then decided to spend his life truing to make explosives safer to use.
One of the strongest explosives at that time was nitroglycerine. This explosive, which looks like oily water, is very dangerous to use or even to carry. Nobel wanted to study nitroglycerine so he could find a way to make it safer. Nobel had an idea of taking nitroglycerine out on a boat in the middle of a lake and working with it there.
When Nobel wanted to take the nitroglycerine he was working with from one place to another, he put it into small boxes. Then he put the small boxes into a larger box made of clay. One day, when he opened the large clay box, he found that nitroglycerine was coming out of one of the small boxes. To his surprise, the large clay box was still dry. This gave him the idea of mixing clay with nitroglycerine. The clay would take the oil out of nitroglycerine and make it safer. He called this explosive ‘dynamite’.

Nicola Tesla is one of the most important inventors in history. Tesla designed over 120 inventions. Most of them are still used today in one form or another. He invented fluorescent lights, sun-powered engines, robots, the first electric clock, and a very important machine part that is used in every home, factory, and office in the modern world. Yet most people do not even know who Nicola Tesla is.
Nicola Tesla was born in 1856 in Smiljian, Croatia. Nicola was an unusual child. He had a photographic memory, so he remembered whole pages of books after he looked at them very quickly. He also liked to write poetry. When he was five, he built a waterwheel and he tried to fly in a homemade plan. That same year, Nicola’s older brother died. People said Nicola accidentally pushed him down the stairs. After this, Nicola began to act strangely.
