Georges Lemaître was a mathematician, astronomer, and professor of physics. Lemaître was the first person to theorize that the expansion of the universe can be used to explain the recession of nearby galaxies. In 1927, Lemaître published the first estimation of the Hubble constant. He also came up with the Big Bang theory to explain the origin of the universe.
Ibn al-Haytham was an Arab mathematician, physicist, and astronomer of the Islamic Golden Age. He is best remembered for his contributions to the principles of optics for which he is called the father of modern optics. He was the first person to explain visual perception. A polymath, Ibn al-Haytham also wrote influential books on philosophy, medicine, and theology.
Swiss-American physicist and engineer Bernhard Caesar Einstein was better known as the only grandchild of Albert Einstein to have survived beyond childhood. While two of his biological brothers died in infancy, his parents adopted a girl child, too. He grew up to work on night vision and laser technology.
