Beauty & Truth
"A scientist…is supposed to be looking for the truth about nature. But not all truths are equal. Some we call deep truths, and these are the ones that are also beautiful. An idea must be more than right-it must also be pretty if it is to create much excitement in the world of science. For the search for truth is not simply a matter of discovering facts. You must also understand their significance, and then persuade others that your way of looking at them is valid. It is always easier to persuade people to believe in something new when they find it beautiful, especially when it runs counter to their established beliefs."
