One of the newest museums in St. Petersburg is the interesting “Museum of Water”, which is located within the walls of the waterworks. The station was built in 1861, and by the 300th anniversary of the city it was restored, and now the museum is located here. It is not easy to climb to the uppermost floors of the tower, especially for people with disabilities, as well as older people. Especially for this built elevator.

Monument to the water carrier at the entrance to the water museum

    At the entrance to the museum there is a monument to a water carrier, which is made of bronze. It was established in 2003, and is timed to the opening of the museum. Museum guides will tell you about the history of water, its strength and use in ancient civilizations. Very brightly in the “Water Museum” it is told about the creation of a water utility, not a lot of information about the Neva.

    The Museum of Water in St. Petersburg has three major expositions: a multimedia complex, an exhibition hall, and a historical exposition.

Chemistry is very important. It can be called the “central science”, because it connects practically all the other sciences to each other.

Chemistry explains how the world around us works. After all, everything in this world is made out of atoms and chemical compounds. So when we know the basics of chemistry, we can understand how everything in the world interacts.

We actually use chemistry every day, every second. For example, our breathing is a set of complex chemical reactions. Other chemical reactions allow us to move, read, eat and feel.

You need to study chemistry if you choose to work in medicine, engineering, metallurgy, space exploration, developing perfumes and cosmetics, pharmaceuticals, energy and many others.

Химия очень важна. Её можно назвать «центральной наукой», потому что она связывает  друг с другом практически все другие науки.

Химия объясняет, как работает мир вокруг нас. В конце концов, все в этом мире состоит из атомов и химических соединений. Поэтому, когда мы знаем основы химии, мы можем понять, как все в мире взаимодействует.

Мы фактически используем химию каждый день, каждую секунду. Например, наше дыхание - это комплекс сложных химических реакций. Другие химические реакции позволяют нам двигаться, читать, есть и чувствовать.

Вам нужно изучать химию, если вы решите работать в таких областях, как медицина, машиностроение, металлургия, освоение космоса, разработка парфюмерии и косметики, фармацевтика, энергетика, и многих других.
