Informative article about physics and quote on "physicists don't care about precise numbers, they care about trends" I am writing an informative article about physics for the general public, and I was wondering if there is any quote by some famous physicist on the concept that usually physicist care about understanding trends more than predicting precise numbers. 
In particular, I would like to convey the message that for a physicist developing a general model which explains the trend of multiple physical phenomenas is much more rewarding than developing a very specific model which explains very well one single physical phenomena but is limited to it.

I found Fermi's quote "Better be Approximately Right than Precisely Wrong", but I would prefer something containing the word "trend" (e.g. once I heard a physics professor saying "I don't care about numbers, I care about trends", this would be perfect for my scope, but it would look much better if this was said by some illustrious physicist).

P.S. I am not sure this is the best platform to post this question, any suggestion for more suitable place to ask this is more than Wellcome.
I do not agree that physicists are more concerned to obtain a qualitative analysis than a quantitative one. However, your question is not about my believes, so ...


Einstein: "If I can’t picture it, I don't understand it."
Dirac: I don't know the exact quote, but he said something like: "In order to understand a differential equation I have to be able to predict the limiting cases, and not solving the actual equation".
