In a few days, the next decade will end, and this is an excellent reason to choose the brightest scientific discoveries of mankind.

Over the past ten years, scientists have made significant progress in understanding the human body, planet and space.

They first photographed a "black hole", discovered potentially habitable planets, created vaccines against terrible diseases, sent automatic devices to asteroids, and invented reusable rockets.

EP has collected 16 of the most striking scientific discoveries of the outgoing decade.

i’d like to tell you about a book by a russian novelist, nikolai gogol. it’s called “the government inspector”. it’s a satirical play. i’ve recently read this book in my literature lessons.

let me tell you a bit about this book. the action takes place in a small provincial town. the main character is khlestakov. he’s a young man who is silly and broke. but he’s a very self-loving man. he tells lies with pleasure. khlestakov has careless a fantasy. he arrives in the town and is mistaken for the government inspector.

as you can imagine, the plot is very interesting and funny. the comedy shows human stupidity and greed. also the problems of society are shown there.
