It could have been our children, spouses, and siblings caught up in a war they didn't ask for.īut given the nature of our company, we also find ourselves uniquely positioned to help. Wherever we are from originally, if we are lucky to find ourselves in the safety of the world outside of the former Soviet bloc - we are keenly aware that their fate could have been ours. Many of our teachers have loved ones in Ukraine. Russia’s invasion into Ukraine is a source of great, real, and concrete pain for all of us. This is a tradition that predates Russia’s current government and will exist long after it. We named our school to reflect the historic tradition of Russian mathematics that we all share. Many ask about the “Russian” in our school’s name. We ask the greater RSM community to remember that regardless of their country of origin, no one is responsible for this war but Putin and his regime. to pursue a better life for their families.
The majority of our teachers, principals, and office administrators emigrated from the former Soviet republics and Eastern Europe and came to the U.S. We are an American company, and we pride ourselves on being a company of immigrants. They settled in Boston, Massachusetts, and have considered themselves proud Americans since.

Both women uprooted their families over thirty years ago, and fled the Soviet Union as Jewish refugees in search of a free and democratic society in which to raise their children.
The Russian School of Mathematics (RSM) was founded by two immigrants: Inessa Rifkin, born in Minsk, Belarus, and Irina Khavinson, born in Chernigov, Ukraine and educated in the specialized math schools of St. We stand with the Ukrainian people against Putin, his regime, and the Russian military invasion of Ukraine. This book is especially suitable for students preparing for national or international mathematical olympiads, or for teachers looking for a text for an honor class.Our Statement on the Russian Military Invasion of Ukraine: The text contains as selection of 300 practice problems of varying difficulty from contests around the world, with extensive hints and selected solutions. Each chapter contains carefully chosen worked examples, which explain not only the solutions to the problems but also describe in close detail how one would invent the solution to begin with. The emphasis of this book is placed squarely on the problems. The exposition is friendly and relaxed, and accompanied by over 300 beautifully drawn figures. The final part consists of some more advanced topics, such as inversion in the plane, the cross ratio and projective transformations, and the theory of the complete quadrilateral. Another part is dedicated to the use of complex numbers and barycentric coordinates, granting the reader both a traditional and computational viewpoint of the material. Topics covered included cyclic quadrilaterals, power of a point, homothety, triangle centers along the way the reader will meet such classical gems as the nine-point circle, the Simson line, the symmedian and the mixtilinear incircle, as well as the theorems of Euler, Ceva, Menelaus, and Pascal. This is a challenging problem-solving book in Euclidean geometry, assuming nothing of the reader other than a good deal of courage.
