Counter clockwise is clocks and watches Of turn The direction is reversed. Such rotation is called counterclockwise. If a rotating object has its edge around the center Direction of movement and Watch needle If the edge moves in the same direction around the surface center, it is Clockwise On the contrary, it is counterclockwise Take taking a bath for example, this is a very common thing. However, Professor Shapiro, the dean of the Department of Mechanical Engineering of Massachusetts Institute of Technology, keenly noticed that every time the bath water was released, the whirlpool of water always turned counterclockwise. Why is this? Shepiro grasped the question mark and carried out repeated experiments and research. In 1962, he published a paper, thinking that this vortex was related to the rotation of the earth. If the earth stopped rotating, it would not produce this vortex. Because the earth kept rotating from west to east, while the United States was in the northern hemisphere, it made the bath water rotate counterclockwise. The Taiwan wind in the north also rotates counterclockwise. The reason is the same as that of the bath water vortex. He also asserted that if in the southern hemisphere, the whirlpool of bath water would Clockwise Direction rotation, at the equator, there will be no vortex. His opinion aroused great interest of scientists all over the world. They carried out experiments all over the country, and the results proved that Shapiro's conclusion was completely correct.
