Unusually steampunk quotes from history

[teucer]

When Professor John Henry Pepper was demonstrating certain pieces chemistry before an audience that happened to include Queen Victoria, he is reported to have calmly introduced one demonstration with:

"The oxygen and hydrogen will now have the honor of combining before Your Majesty."

[Story]

Man has mounted science, and is now run away with. I firmly believe that before many centuries more, science will be the master of men. The engines he will have invented will be beyond his strength to control. Someday science may have the existence of mankind in its power, and the human race commit suicide, by blowing up the world. Not only shall we be able to cruise in space, but I'll be hanged if I see any reason why some future generation shouldn't walk off like a beetle with the world on its back, or give it another rotary motion so that every zone should receive in turn its due portion of heat and light.
