Our planet Earth is only a tiny part of the universe, but at the moment - this is the only place where we can live.People have always polluted all around. But until now pollution was not such a serious problem. People living in rural areas and did not produce such a large number of contaminants that could cause a dangerous situation on a global scale.With the development of the highly congested industrial cities that emit huge amounts of pollutants into the environment, the problem has become increasingly serious. Today, our planet is in grave danger. Acid rain, global warming, air and water pollution, overpopulation - issues that threaten human life on Earth.<span>To understand how air pollution affects our bodies, we need to know exactly what it is pollution. The pollutants, which are harmful to our respiratory system, called particulates. Particulates - a small solid particles that we see in sunlight. It is derived from incomplete combustion of fuel in engines, such as an internal combustion engine, road dust and smoke from burning wood/</span>
Newton, one of the greatest scientists of all times was born in 1642 in the little village in Lincolnshire, England. His father was a farmer and died before Newton was born. His mother was a clever woman whom he always loved.After the school, Newton studied mathematics at Cambridge university and received his degree in 1665. Then the university was closed because of the danger of plague and Newton went home for eighteen months. It was most important period in his life when he made his three great discoveries — the discoveries of the differential calculuses, of the nature of white light, and of the law of gravitation.These discoveries are still important for the modern science. Newton had always been interested in the problems of light. Many people saw colours of a rainbow but only Newton showed, by his experiments, that white light consists of these colours.It is interesting how he discovered the law gravitation. Once, as he sat at the garden, his attention was drawn by the fall of an apple. Many people saw such an usual thing before.But it was Newton who asked himself a question: "Why does that apple fall perpendicularly to the ground? Why doesn't it go sidewards or upwards?" The answer to this question was the theory of gravitation, discovered by Newton.<span>Newton died at the age of 84, and was buried in Westminster Abbey, where his monument stands today.
</span>Ньютон, один из величайших ученых всех времен, родился в 1642 году в маленькой деревеньке в графстве, Линкольншир в Англии. Его отец был фермером и умер, прежде чем родился Ньютон. Его мать была умной женщиной, которую он всегда любил.После школы Ньютон изучал математику в Кембриджском университете и в 1665 году получил ученую степень. Затем университет закрылся из-за угрозы чумы, и Ньютон уехал домой на полтора года. Это был самый важный период в его жизни, когда он сделал три великих открытия — открытие дифференциального исчисления, природы белого света и закона всемирного тяготения.Эти открытия все еще важны для современной науки. Ньютон всегда интересовался проблемами света. Многие видели цвета радуги, но только Ньютон в результате своих экспериментов доказал, что белый свет состоит из этих цветов.Любопытно то, как он открыл закон всемирного тяготения. Однажды, когда он сидел в саду, его внимание привлекло падение яблока. Многие люди видели это обыкновенное явление прежде.Но именно Ньютон спросил себя: "Почему яблоко падает перпендикулярно земле? Почему оно не летит в сторону или вверх?" Ответом на этот вопрос стала теория гравитации.<span>Ньютон умер в возрасте 84 лет и был похоронен в Вестминстерском аббатстве, где и находится сейчас памятник в его честь.</span><span>
