Inventions have been for centuries a subject that interested a lot of people, because new things are most of time seen as strange and stimulate their curiosity. They give fear, joy, astonishment, laugh, amazement, anger, and a lot of other feelings. In this article, we are going to present some of the most important inventions of the humanity since it exists.

First : who will contest that the fire is not one of the earliest discoveries ? The power of the fire gave to a lot of tribes the domination in the first ages of humanity. It has been used as a lightening mean which protected them from savage creatures. It is believed the fire was discovered have million years ago.

Second : some bad jokers say the Yeti is a big engineer. Why, lets make our brains turning … do you see, or do you turn ? That’s it ! Once upon a mountain, a big white monkey jumped and fall down and turned on his self and become a snow ball. Someone had the get the idea of the wheel ! Well, that’s the wheel could have been invented. Seriously, historians locate invention of the wheel in Asia by 3500 B.C. .

Third : writing. Writing is one of my favorite inventions. The animals have a kind of clever sense even if it is not as developed as the human one. But the fact they have some is true : they have feelings, reactions, oral an gestural communication, they have some ingenious skills as the bees can build their home, as monkeys who can imitate humans … However, given what we know about animals, none of them have the writing. It is the beginning of material information backup, appeared in the same time as the wheel (3500 B.C.) in the city of Sumer in Mesopotamia.

Fourth : did you lost your way in this wide world ? Fortunately, there was at least one clever in the fabulous country of China who discovered the earth magnetic field in the 11th century of our era. The invention is the compass which guided over all the planet many travelers and sailors for a while !

Fifth : electricity ! That’s a great transition from the world of simple matter to an electron word ! First time people saw electric light, they said it was witchcraft ! So worry about yourself, It is even inside you ! Well, this invention appeared at the end of 19th century.

Sixth : time watch. How humanity did discover the concept of time. Nobody can see the time with his eyes, nor catch it ! Only brighten wide minds can imagine such an idea ! We know that first solar watches existed by 550 B.C. . It is also reported that Egyptians had been using water clocks by 3000 B.C. , a kind of clocks that are using water circuits filling graduated recipients. Graduations are so indicating time.

Seventh : “Hello ? How did you entered in this small box ? Is your voice hanged by this wire ? Hello ?” – This is an imaginable scenario that could happened when people discovered usage of the telephone invented in1976. The author of this invention is Alexander Graham Bell.

Eighth : the computer. It is undeniable that this machine is the best symbol of modern technology at these days. It has revolutionized humanity way of working. They are automated brain slaves, for some ones, entertainment box for others, a memory station, or even an enemy ! It is at same time a threat and an opportunity for people ! The concept of computer exists since the antiquity (they were mechanical automates) and is improved until our days.

Which things are the best inventions ? Answering to this question has a part of subjectivity. But We can use some indicators to give them a mark. God indicators can be these : % of usage in the world, propagation time since its apparition, existence duration, integration level (an invention can be used as a component in many things, and the level is the number of things it is used by), contribution to society development … maybe we can find many other ones, but the most important thing I want to say to readers, is : if you want to be an inventor, you can dream, you can, fly high in the sky, be a philosopher, but 2 things : be careful on your intentions and think a lot about what for your inventions can be used …
