Genius and Elite: The Relation Between Galileo and Einstein
To explore the perception of the universe, Galileo Galilei (1564-1642) played an important leading role. With his discoveries, the veil between human beings and the universe was removed. Humans got to have a closer look of the moon, the sun, and the star. In addition, he proved physical theories by different experiments, such as the acceleration of falling objects. While two hundred years later in 20th century, Albert Einstein's (1879-1955) revolution lead the exploration of the universe to a higher level: the change and relation of space and time. Science is a continuous chain of discovery. Their theories influence each other.
With the efforts of these great scientists, we humans are allowed to have a deeper understanding of the universe.
