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.
Yin and yang, male and female, strong and weak, rigid and tender, heaven and earth, light and darkness, thunder and lightning, cold and warmth, good and evil...the interplay of opposite principles constitutes the universe.
It is sound statesmanship to add two battleships every time our neighbour adds one and two stories to our skyscrapers every time he piles a new one on top of his to threaten our light. There is no limit to this soundness but the sky.
Those who every morning plan the transactions of the day and follow out that plan carry a thread that will guide them through the labyrinth of the most busy life. The orderly arrangement of their time is like a ray of light which darts itself through all their occupations. But where no plan is laid, where the disposal of time is surrendered merely to the chance of incidents, chaos will soon reign.
