Favorite Statements of Scientific Wisdom

"Predicton is very difficult, especially for the future" by Niels Bohr.

"Never accept anything as true unless it clearly is. Divide every difficult problem into small parts, and solve the problem by attacking these parts. Always proceed from simple to complex, looking for patterns and order. Be as complete and thorough as possible, so that nothing is missed" by Descardes.
