"The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of very great importance, I think. When a scientist doesn't know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty darn sure of what the result is going to be, he is in some doubt. We have found it of paramount importance that in order to progress we must recognize the ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty – some most unsure, some nearly sure, none absolutely certain."

These famous remarks by the infamously anti-philosophy scientist Richard Feynman resonate deeply with an enduring theme in the contemporary philosophy of science: the essential role of uncertainty in our scientific knowledge. As a wanderer between science and philosophy, it is my great pleasure to join the DAWN project exploring the intriguing topic of uncertainty in modeling over a field that has immense implications for societies and the Earth.
