Brownian Motion in Physics
In 1827, a scientist, Robert Brown observed the motion of molecules with the help of a microscope. He observed that the tiny particles in water are constantly moving in a zigzag path. He called the motion, Brownian Motion
Explanation:
The cause of this tiny particle motion is the rapid motion of the molecules, which collide with the particles and push them in one direction. If some molecules come from other direction and collide with the same particles, particles change their direction. This process continues and the motion becomes zigzag.
Note: The main distinctive feature of the correspondence course of study is the term of study (6 years instead of the traditional 5 years) and the receipt of education on the job. Extramural students study in two periods. During the installation session, teachers read introductory lectures, give lists of literature, control tasks, topics of abstracts and term papers, approximate questions of tests and examinations . As a rule, six months pass between the installation and the examination session. The winter session lasts about 10 days, the summer session lasts a month. However, there are also positive aspects of such education. Among the merits we note the opportunity to work and earn money, the comparative ease of admission, democratic prices for fee-based training. Strangely enough, but students in correspondence form are better acquainted with their specialty in practice.
