10 Greatest Discoveries

INTRODUCTION

We, humans are the only of the nature who question their origin, their evolution. Who are we? Where did we come from? What is the meaning of human existence?

The capacity to formulate questions and answer them is what makes us unique and makes us different from animals or other living thing.

Today, we know much about the scientific discoveries that have marked important points in the world of science, but perhaps we never got to ask what are the discoveries that, they think are the most significant for the scientific life.

It is very important to know the opinion of the people with respect to the progress of science.

Next, we will know more about the ten greatest discoveries of science according to what people think.

10 GREATEST DISCOVERIES

10. - Newton’s laws of movement

These are the three principles which explain the problems of dynamics; those can concern the movement of bodies.

• In the first law Newton says:

Everybody perseveres in its state of rest or uniform movement and rectilinear unless it is forced to change its state by forces impressed upon it.

• The second says that the change of movement is proportional to the driving force and occurs according to the straight line along which the forced is printed.

• The last law says that every action occurs whenever and equal and opposite reaction: that is, the mutual actions of two bodies are always equal and opposite directed.

These laws revolutionized basic concepts of physics and the movement of bodies in the universe.

9. – Microorganisms

Thanks to the improvement of the microscope. The Dutch naturalist Antoni van Leeuwenhoek was the first to describe these bodies (which he named “animalcules”) that he observed with a microscope built by himself.

8. – Penicillin

Alexander Fleming was making his experiments when he checks their crops, notice that a colony of a fungus around other was transparent due to the death of the bacteria. To this fungus Fleming calls it Penicillium Notatum.

Thanks to the discovery of penicillin, today it is possible to cure many diseases that were fatal.

7. - Germ Theory

Long time ago, people believed in spontaneous generation but a French chemist and biologist called Louis Pasteur, began to find specific microbes of various diseases and notes that are living being that are passed from one body to another, then a surgeon discovers that applying antiseptic measures the infections could stop.

With the germ theory was introduced a new way of understanding the hospital attention and all the medicine.

6. - Laws of Heredity

Mendel experimented by choosing two pea plants
