PLEASE LIST ALL THE QUESTIONS FOLLOWED, AFTER EACH BY THE ANSWER
Attendance Question 1
Who was Gian-Carlo Rota
Answer
He  was an Italian-American mathematician and philosopher. He spent most of his career at the Massachusetts Institute of Technology, 
where he worked in combinatorics, functional analysis, probability theory, and phenomenology.

Attendance Question 2 
Use the internet to find the quote of rota about how useful PIE exist.
Answer
Combinatorics is an honest subject. No adèles, no sigma-algebras. You count balls in a box, and you either have the right number or 
you haven't. You get the feeling that the result you have discovered is forever, because it's concrete. Other branches of mathematics 
are not so clear-cut. Functional analysis of infinite-dimensional spaces is never fully convincing; you don't get a feeling of having 
done an honest day's work. Don't get the wrong idea - combinatorics is not just putting balls into boxes. Counting finite sets can be 
a highbrow undertaking, with sophisticated techniques.

Attendance Question 3
