The greatest science knowledge

Which is the greatest?

In my humble opinion, I would say “Quantum mechanics” based on its wide applications that improve the well-being of humans, almost everything that touch our lives are associated with its scientific knowledge.


Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties’ behaviours at the scale of atoms and subatomic particles-mainly protons and electrons.

The below picture is the structure of an atom with electrons and protons ect.. The electrons are attracted to the nucleus' protons due to opposite charges. All matters around us are made of different types of atoms with different number of protons/neutrons with electrons matching to the number of protons. 
 
                                                              
The behaviour of electrons is the most fascinating phenomena in the universe. The picture below is the different orientations of the electron clouds of different atoms. It is called cloud because the electron can be found in any of the location in the cloud at the same time with different probabilities according to Quantum mechanics. This property allows the electron clouds to be attracted to neighbouring atom's protons
