in 2002, the russian mathematician grigori perelman proved the poincaré conjecture. this is a very serious discovery in mathematics. it was one of the seven tasks of the millennium. for this work, he received the prestigious fields medal, an analogue of the nobel prize in mathematics.
2. quantum clock.
quantum clocks are the most accurate chronometer in the world, surpassing all previously existing ones. nobel laureates of 2012 serge arosh and david wineland made a discovery that allowed to overcome the quantum barrier.
3. the discovery of eris.
the eris is the second after the massive pluto massive dwarf planet of the solar system. it was the discovery of eris from pluto that ceased to be the ninth planet, and passed into the category of "dwarf".
4. created the first synthetic bacterial cell.
in 2010, scientists from the craig venter institute created the first fully synthetic chromosome with the genome. when it was embedded in a bacterial cell devoid of genetic material, it began to function and divide according to the laws prescribed by the new genome.
5. higgs boson.
this was experimental evidence of the existence of the higgs boson. the practical significance of the discovery of the higgs boson is that scientists are opening up prospects for the development of anti-gravity and the development of engines that do not require energy to operate.
My best day of the summer was in early August. He took me wonderfully. The morning started with the fact that I woke up early, myself, I will not be waking. I woke up in a great mood. Just like that, for no reason.
After Breakfast, my dad was away on business. I did not know that he decided to buy me a bike that I wanted. But early on, he had no money, and now they were found. Homemade conspired not to tell me about the surprise. I was sitting at home. To do on vacation was nothing. Then I decided to organize something interesting. I began to call friends and invited them to go to the river.
I especially did not expect, but suddenly a crowd of people eight! A boy and a girl I never knew we met. I managed the campaign and led them to the river. Our company had a great time. We swam, sunbathed, throwing each other into the water. Had a lot of fun squeal.
When I got home, dad had already arrived and brought me a Bicycle. That joy it was! When we with my friends Nicky and Sasha have tested it in the yard, then was born the idea of going to visit new friends. I mean Roma and Oksana, with whom we met on the way to the river. Then we went to the bike to them on the street. We sat with Roman, Oksana, and their friends on the bench under the tree. Stayed until late, well communicated, and then went home. And by the way, my house does not have to scold you because I got home late. I also made friends with Oksana, and we're friends with her now.
Самый лучший день лета на русском языке:
Мой лучший день лета был в начале августа. Он у меня чудесно. Утро началось с того, что я проснулся рано, сам, никто меня не будил. Проснулся я в прекрасном настроении. Просто так, безо всяких причин.
После завтрака мой папа уехал по делам. Я еще не знал, что он решил купить мне велосипед, который я давно хотел. Но раньше на него не было денег, а теперь они нашлись. Домашние сговорились не рассказывать мне о сюрпризе. Я сидел дома. Заняться на каникулах было нечем. Тогда я решил организовать что-нибудь интересное сам. Я стал звонить друзьям и звал их пойти на речку.
Я особо не надеялся, но неожиданно собралась толпа человек в восемь! Одного мальчика и девочку я даже раньше не знал, мы познакомились. Я руководил походом и повел всех на реку. Наша компания отлично провела время. Мы купались, загорали, бросали друг друга в воду. Было много веселья, визгу.
Когда я вернулся домой, папа уже приехал и привез мне велосипед. Вот радости-то было! Когда мы с моими друзьями Колей и Сашей обкатали его во дворе, то родилась идея поехать в гости к новым друзьям. Я имею в виду Рому и Оксану, с которыми мы познакомились по пути на речку. Тогда мы поехали на велосипедах к ним на улицу. Мы сидели с Ромой, Оксаной и их знакомыми на лавочке под деревом. Просидели до позднего вечера, хорошо пообщались, а потом уехали домой. И кстати, дома меня совсем не стали ругать за то, что я поздно вернулся. А еще я подружился с Оксаной, и мы дружим с ней и теперь.
