I am persuaded that this method [for calculating the volume of a sphere] will be of no little service to mathematics. For I foresee that once it is understood and established, it will be used to discover other theorems which have not yet occurred to me, by other mathematicians, now living or yet unborn.
It follows at once from the last proposition that the centre of gravity of any triangle is at the intersection of the lines drawn from any two angles to the middle points of the opposite sides respectively.
Many people believe that the grains of sand are infinite in multitude ... Others think that although their number is not without limit, no number can ever be named which will be greater than the number of grains of sand. But I shall try to prove to you that among the numbers which I have named there are those which exceed the number of grains in a heap of sand the size not only of the earth, but even of the universe
The centre of gravity of any parallelogram lies on the straight line joining the middle points of opposite sides.
The diameter of the earth is greater than the diameter of the moon and the diameter of the sun is greater than the diameter of the earth.
Those who claim to discover everything but produce no proofs of the same may be confuted as having actually pretended to discover the impossible.
Two magnitudes whether commensurable or incommensurable, balance at distances reciprocally proportional to the magnitudes.
As far back as I can remember, I knew there was something wrong with our way of life when people could be mistreated because of the color of their skin. - Rosa Parks
I believe we are here on the planet Earth to live, grow up and do what we can to make this world a better place for all people to enjoy freedom. - Rosa Parks
I had felt for a long time that, if I was ever told to get up so a white person could sit, that I would refuse to do so. - Rosa Parks
In it not easy to remain rational and normal mentally in such a setting where, even in our airport in Montgomery, there is a white waiting room... There are restroom facilities for white ladies and colored women, white men and colored men. We stand outside after being served at the same ticket counter instead of sitting on the inside. - Rosa Parks
Time begins the healing process of wounds cut deeply by oppression. We soothe ourselves with the salve of attempted indifference, accepting the false pattern set up by the horrible restriction of Jim Crow laws. - Rosa Parks
Whites would accuse you of causing trouble when all you were doing was acting like a normal human being instead of cringing. - Rosa Parks
You spend your whole lifetime in your occupation, actually making life clever, easy and convenient for white people. But when you have to get transportation home, you are denied an equal accommodation. Our existence was for the white man's comfort and well-being; we had to accept being deprived of just being human. - Rosa Parks
