It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing - a somewhat unfamiliar conception for the average mind. Furthermore, the equation E = mc², in which energy is put equal to mass, multiplied by the square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa.

We merely want to live in peace with all the world, to trade with them, to commune with them, to learn from their culture as they may learn from ours, so that the products of our toil may be used for our schools and our roads and our churches and not for guns and planes and tanks and ships of war.
In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military industrial complex. The potential for the disastrous rise of misplaced power exists and will persist. We must never let the weight of this combination endanger our liberties or democratic processes. We should take nothing for granted. Only an alert and knowledgeable citizenry can compel the proper meshing of the huge industrial and military machinery of defense with our peaceful methods and goals, so that security and liberty may prosper together.
Why are we proud? We are proud, first of all, because from the beginning of this Nation, a man can walk upright, no matter who he is, or who she is. He can walk upright and meet his friend--or his enemy; and he does not fear that because that enemy may be in a position of great power that he can be suddenly thrown in jail to rot there without charges and with no recourse to justice. We have the habeas corpus act, and we respect it.
And they can appreciate, through personal experience, that the really decisive battleground of American freedom is in the hearts and minds of our own people...The path we travel is narrow and long, beset with many dangers. Each day we must ask that Almighty God will set and keep His protecting hand over us so that we may pass on to those who come after us the heritage of a free people, secure in their God-given rights and in full control of a Government dedicated to the preservation of those rights...
