Dear Friends, Esteemed Judges, Honored Guests,

It is a great pleasure to welcome you all to the 26th Tuymaada Olympiad. For many years I was personally involved in its organization and judging and am a longtime member of the Tuymaada brotherhood. The Olympiad had always been the one event in the middle of a short Yakutian summer that brings joy and excitement for a good number of people, to its avid followers, to the participants of the past and of today, to judges and experts, for it’s a celebration of science and ingenuity, and I firmly believe in your academic achievement, as well as your success in the future. Tuymaada Olympiad was conceived with a unique format, combining four different fields: math, physics, chemistry, and computer sciences to provide an opportunity for understanding the seamlessness of natural phenomena and the applicability of scientific methods to any place or region. The name of the Olympiad comes from Tuymaada Valley, which is the name of the valley where city is. In many ways it is a wonderful place. Some 540 mln years ago it was a warm tropical lagoon located somewhere near the equator, where the so-called Cambrian Explosion, the origin of multi-cellular organisms, took place. Later the lagoon drifted slowly to where it stands today. Hundreds of thousands years ago the herds of woolly mammoths roamed the valley and people started settling in; today the valley is the very heart of Eastern Siberia and was for centuries a starting point of many scientific expeditions to the Arctic, to the place unknown. And today, at the dawn of the quantum computing age, I hope the Tuymaada Olympiad will become the starting point of great research and science careers, as well as many success stories of the future. I would like to thank all the organizers, volunteers, and members of the All-Russian and International Methodological Commissions, and congratulate all of you with the start of the 26th Tuymaada Olympiad. I wish all the participants to compete with dignity and nobility of spirit to the fullness of your abilities, for the judges to make your decisions with a great sense of fairness so that the Tuymaada Olympiad of 2019 is another success! All the best to all of you, the Tuymaada brotherhood! GREETINGSMINISTER’S
