-How has e=mc2 affected you?

In Western way, I benefit the effect of this equation from the Sun and the electricity from the nuclear power, etc.
In Eastern way, I can feel the equation more familiar. Since Qi can be e (Energy), we learned that everything around us is made of Qi. Blood is a condensed Qi, and the body is a more condensed Qi and so on. So when explained that the matter is energy, it is easy to understand if we know this principle on the Qi.

-How would you compare the four "forces"?

-Strong nuclear force: The strongest force, but in very short distance (subatomic distance). Keeps quarks together inside protons and neutrons.

-Electromagnetic force: The second strongest force, has two poles and can attract and repel unlike gravity. In Eastern way, it can be regarded as Yin and Yang.

-Weak nuclear force: The third strongest force, effective in very short distance like strong nuclear force, is responsible for radioactive decay.

-Gravity: The weakest force, only attracts and doesn't repel like electromagnetic force.


-What is the function of gravity?

Gravity is something that makes things stable and secure. It keeps things in place, keeps the stars orbits the way they are and make them predictable.
