Brain Pickings has a great roundup of quotes from famous scientists about what science is. One of my favorites, by Marie Curie:
“Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.”
A fantastic philosophy for life in general, and I think one writers should keep in mind as well. Part of writing and reading means opening your mind to other possibilities and ways of life, even if they’re uncomfortable or scary. The more we understand, the better.

Yeah, but Marie Curie also died of Leukemia because she chose not to fear while she was trying to understand 😛 Then again, certainly an inspiring quote/ person.
Haha, good point. Try to understand things, but also watch out for stuff that will make your cells freak out and attack each other.
