November 5, 2011 – Titu Andreescu – “AMC 8 Preparation”

If you are a student who has not yet passed 8th grade, please make every effort to attend next week’s math circle.  The AMC 8 contest is the first in a series of competitions eventually used to select the team for the International Mathematical Olympiad.  While few students will ever represent the US on this elite team, the scores from the AMC tests become an important component of any transcript when applying to a STEM program in an elite college.

With today’s international and competitive application environment, elite universities routinely see many 800 SAT math scores.  The more rigorous AMC test provides these schools a more meaningful measure of students who will succeed in their math or science programs.

Our students have a great advantage learning directly from Dr. Titu Andreescu.  Dr. Andreescu was the director of the AMC (you will see his name on the certificate above) and the coach of the US IMO team.  Do not miss this opportunity to improve your understanding and performance on the AMC 8 which will prepare you for the more advanced competitions to come.

October 29, 2011 – Cosmin Pohoata – “Apollonius’ Delight: Ruler and Compass Constructions”

Constructions using only the compass and the unmarked ruler (straightedge) have always been something to be enjoyed by triangle geometers throughout time and to inspire many Olympiad problems nowadays. Here, we will see why this subject can be so appealing and will cover a few basic constructions for afterwards to challenge ourselves and see how these serve as natural “macros” for constructions which at first sight seem out of reach.

October 22, 2011 – Dr. Branislav Kisačanin – “Second Encounter with Calculus”

Following his very successful lecture on October 1, Dr. Kisačanin will continue his introduction to calculus.  Students who have already studied some calculus will gain a deeper insight into this beautiful and useful tool.  Those who have not yet studied calculus should not be put off, however, as Dr. Kisačanin is very skilled at explaining mathematical concepts so that they can be appreciated by a broad audience.

October 15, 2011 – Dr. Titu Andreescu – “Prime and Composite Numbers”

Next Saturday Dr. Andreescu will return to share some of his favorite problems related to primes and composite numbers.  Not only are these subjects major components of mathematical contests, they are also used widely in applied math topics like cryptography.  The presentation will contain interesting problems involving primes and numbers that can be written as product of primes.
