The first great idea which started man on the road to his great achievements was when a caveman picked up a heavy stone to help him.

The Invention of Wheel
Another great move towards modern technology was the invention of the wheel by some unknown prehistoric genius.

Metal Weapons
Man had efficient metal weapons and was able to hunt large animals for food.
Gradually, he learned to capture and tame some of the creatures, so that hе could
keep his food nearby until it was needed.

Man also discovered how to plant crops, gathering seed from wild pants, which he knew to be useful. Once farming was established, it did not take man long to make special tools for breaking up the ground, and later he began to use the help of domestic animals in pulling his primitive plough.
Cultivating Land

Writing
Another important invention which has contributed greatly to our modern knowledge was writing. At first, writing was a special form of drawing, and was usually very simple. But gradually these primitive drawings turned into letters.

No less important was the invention of printing, giving many men an opportunity to read and to own books which before had been available to only the wealthy few.

the Industrial Revolution.
The invention of the steam engine, the condenser and piston made possible

The nineteenth century was the age of the machine, when man realized that many hard tasks could be done more easily and cheaply by machinery.

The Invention of Electricity
The nineteenth century also saw the invention of electricity, which revolutionized
life and made many other things possible.

A New Era in Transport
The manufacture of cars began a new era in transport,
and led to the appearance of lorries and buses, without which
our cities would not have grown to their present size.

The second half of the twentieth century was characterized by the inventions of television, computers, spacecraft, genetic engineering and many others.
