Quote from mathematician-poet I read once a quote by a mathematician (or scientist) who was also a poet and it was something similar to:

As a mathematician I try to make complicated things obvious, as a poet I try to make obvious things complicated, 

but I can't find it online or remember who said it. Does anyone know? Or if you know a similar quote I would really appreciate your help. Thank you
 A: Also, a similar quote is attributed to Paul Dirac (criticising Oppenheimer's interest in poetry): 

"The aim of science is to make difficult things understandable in a
  simpler way; the aim of poetry is to state simple things in an
  incomprehensible way. The two are incompatible."

A: Also a quote is attributed to Sofia Kovalevskaya:

It is impossible to be a mathematician without being a poet in soul.” — Sofia Kovalevskaya 

Also this article Mathematicians and Poets is very intersting.
A: You are probably thinking of J. Robert Oppenheimer quoting Paul Dirac in the first paragraph of an article entitled "The Age of Science 1900-1950", published in the September 1950 issue:

One evening more than 20 years ago Dirac, who was in Göttingen working on his
quantum theory of radiation, took me to task with characteristic gentleness.
"I understand," he said, "that you are writing poetry as well as working at
physics. I do not see how you can do both. In science one tries to say some­
thing that no one knew before in a way that everyone can understand. Whereas
in poetry ..."
The 10 reports here, to which these words may serve as introduction, do
indeed attest that science says things that no one knew before in a way we
can all understand.

Oppenheimer had published poems in the Harvard student literary magazine Hound & Horn, including one from 1928 called "Crossing" inspired by his time in the desert of New Mexico.
A: A similar quote is usually attributed to the mathematician Stan Gudder (U. of Denver):
"The essence of mathematics is not to make simple things complicated, but to make complicated things simple."
