He is known to develop the theory of relativity. But also made many develops on theory of quantum mechanics. Albert Einstein is one of the most intelligent scientists, other scientists like him include Isaac Newton who was a Mathematician, physicist, astronomer and greatly recognized. Albert is best known for his equation E= mc2 and has won many awards. He’s greatest contribution to the world was his theory of relativity in which described new ways of looking at time, space, matter, energy and gravity. Einstein’s work has influenced advanced modern quantum mechanics, the model of physical time, the understanding of light, solar panels, and even modern chemistry.
Problems such as his equations didn’t always work out. Things in science only works in trial and error.
Overall Albert Einstein is one of the most bravest, intelligent and modern people that invented things that helped us in learning and finding new things. He is amongst one of the most intelligent. All scientists work together and develop the world in this time.
Hope this helps!!!
