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.
Getting people to fight by letting the force of momentum work is like rolling logs and rocks. Logs and rocks are still when in a secure place, but roll on an incline; they remain stationary if square, they roll if round. Therefore, when people are skillfully led into battle, the momentum is like that of round rocks rolling down a high mountain - this is force.
Three of our provinces have seen mass uprisings. The three provinces are Khuzestan, Azerbaijan, and Kurdistan. Recently, we witnessed massive demonstration by Iranian woman in the 7th of Tir square, and it was brutally suppressed.

We just bought this house. It's too big. It's like 400,000 square feet, or something. We got an indoor lake and ski slope in the house! It's just too big.
We demand that big business give the people a square deal; in return we must insist that when any one engaged in big business honestly endeavors to do right he shall himself be given a square deal.
In England ... education produces no effect whatsoever. If it did, it would prove a serious danger to the upper classes, and would probably lead to acts of violence in Grosvenor Square.
