I have interviewed a first year college student from the Albanian minority that abounds in Greece to see how learning mathematics in a new language progresses along with learning to live in a new social environment. My aim was to investigate how his native language intertwined with the new language through which he was trying understand fundamental mathematical concepts. In my talk I will also talk about the effect of culture on learning in general.

Suppose you are gambling at a casino in a game where you and a dealer take turns rolling a die. Suppose next that the die is initially fair, that is, each of its six faces has the same probability of showing up. However, at some point during the course of the game the evil dealer – without you seeing – replaces the die with an unbalanced one, and so from that point on the die’s faces are no longer equally probable. Yet as the new die looks exactly the same as the old fair one, you continue to gamble without suspecting anything. The natural question is: as the game progresses, can you somehow “detect” that the die has been tampered with?

Statistics is a branch of mathematics concerned with rational decision-making among uncertainty. We will see how such a question-- a gamble on its own—is approached with statistical techniques. Specifically, the talk will focus on the so-called quickest change-point detection problem, **stats on the go**!

Mathematicians are known for recycling language -- using familiar words to mean wild ideas seemingly with no resemblance to the original words! The word "group" is one such word ... What IS a mathematical group? Allow me to introduce you to some of the exotic and wild members of the Group Menagerie. No background in Abstract Algebra is assumed, and the audience may feel free to poke, prod, pet, and even bring home the creatures discussed.

A Concise History of Calculus

A lively overview of over two thousand years of calculus history. Not only who-did-what along the way, but the cultural and sociological causes and effects of the calculus. Strongly recommended for anyone who has taken or is taking calculus.
