"To discover to the world something which deeply concerns it, and of which it was previously ignorant; to prove to it that it had been mistaken on some vital point of temporal or spiritual interest, is as important a service as a human being can render to his fellow creatures..."
John Stuart Mill, "On Liberty"
For all the talk today about science and technology, it seems that sometimes the frontiers of science are simply a new app, a new way to shop or play games. All of which somehow does a disservice to the real value of science to change the world. It can make us forget the wonder of discovery, and how science has allowed us to know what we know, about the world around around us.
