Mathematics lovers are sought!

Department of Mathematical Sciences of Stevens Institute of Technology announces opening the Mathematical Circle for K-12 students attending 9^th, 10^th, and 11^th grades who love mathematics and want to study its various branches beyond the limits of school curriculum. All students from Hoboken, Weehawken, Union City, Jersey City and neighborhoods are welcome. We meet on Wednesdays on Stevens campus at Pierce building, room P-120 between 4:30 and 6:00 pm.

At the circle in a quite informal and friendly atmosphere we’ll discuss creative, interesting, and joyful mathematical problems that help to form a better feeling of mathematics and logic. Also, we will discuss the problems offered at Mathematical Olympiads, and our meetings will be a good way to be better prepared for Olympiads. The topics include but are not limited to combinatorics, counting, pigeonhole principle, divisibility, graphs, mathematical games, geometry.

When: Wednesdays, starting from October 4, at 4:30 pm.

Where: Stevens Institute of Technology campus, Pierce building, room P- 120.

Problem 1: There are three piles of stones: one with 10 stones, one with 15 stones, and one with 20 stones. At each turn, a player can choose one of the piles and divide it into two smaller piles. The loser is the player who cannot do this. Who will win, and how?

Problem 2: Given two parallel lines and a fixed point, draw the straight line, which goes through the given point and is parallel to those two lines. Use ruler only. No compass is allowed!
