| 1 | At the same time, astronomers can look for the spacetime analogues of random Brownian motion. | |
| 2 | "Brownian motion" is a very small number of particles suspended in the liquid in the irregular movement, R. | |
| 3 | As we all known , Brownian motion is an important type of stochastic process. | |
| 4 | The path of a particle in Brownian motion is erratic and frequently changes direction. | |
| 5 | It is apparent that the visible Brownian motion depends on the size of the invisible bombarding molecules. |
