In the history of physics, every time we've looked beyond the scales and energies we were familiar with, we've found things that we wouldn't have thought were there. You look inside the atom and eventually you discover quarks. Who would have thought that? It's hubris to think that the way we see things is everything there is.
The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth, space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.
If, while I hear the shriek of the slave mother robbed of her little ones, I do not open my mouth for the dumb, am I not guilty? Or should I go from house to house to do it, when I could tell so many more in less time, if they should be gathered in one place? You would not object or think it wrong, for a man to plead the cause of the suffering and the outcast; and surely the moral character of the act is not changed because it is done by a woman. I expect to plead not for the slave only, but for suffering humanity everywhere. Especially do I mean to labor for the elevation of my sex. I only ask that you will not withhold your consent from my doing anything that I think is my duty to do.
