Knowledge Is Power 2

What knowledge in this world most powerful at the moment?

1) Computer/Internet hacker

2) Biologist / Scientist (especially to find cure for dangerous disease like ebola)

3) Nuclear Scientist

4) Engineering Scientist (to create the most powerful aircraft weapon in the world)

More to come if I think there is any...


I must not fear.
Fear is the mind-killer.
Fear is the little-death that brings total obliteration.
I will face my fear.
I will permit it to pass over me and through me.
