Infinitesimalm perhaps, insignificant not.

"The tiny space I occupy is so infinitely small in comparison with the rest of space, in which I am not and which has nothing to do with me and the period of time in which it is my lot to live is so petty beside the eternity in which I have not been, and shall not be....And in this atom, this mathematical point the blood is circulating, the brain is working and wanting something...Isn't is loathsome? Isn't it petty?"
-Ivan Turgenev
