Basically, I’m not interested in doing research and I never have been […] I’m interested in understanding, which is quite a different thing. And often to understand something you have to work it out yourself because no one else has done it.

We must know, we will know.
Emilie Du Chatelet
From what has been said, it follows that the impossible is that which involves a contradiction, and the possible is that which does not.
Bring forward what is true. Write it so that it is clear. Defend it to your last breath.
— Ludwig Boltzmann
