The Nobel Prize in Chemistry 2013Chemistry is one of the categories of the Nobel Prize awarded to chemists who have dedicated themselves to the science of chemistry. For a chemist, the Nobel Prize is one of the most prestigious awards. The 2013 Nobel Prize in Chemistry was awarded to three theoretical chemists who developed a multiscale computer model to predict complex chemical reactions. The three chemists are Michael Levitt of Stanford University, Martin Karplus, University of Strasbourg, Harvard University and Cambridge University and Arieh Warshe of the University of Southern California. They created a unique computer model to predict how the chemical reaction occurs. For their contribution to chemical science they awarded the Nobel Prize in Chemistry 2013. Michael Levitt was born in Pretoria, South Africa in 1947, but his nationality is American-British. Michael Levitt works as a professor of structural biology and professor of computer science (courtesy) at Stanford University. He has a long bibliography of both individual and group research. He admitted that it would be very difficult to understand what happens in nature without computers. He later said that his team's Nobel Prize is an appreciation for the importance of computers and biology. Michael Karplus is an 83 year old Austrian born in Vienna. He is Theodore Williams Richard Professor Emeritus of Chemistry at Harvard University; it is also affiliated with the University of Strasbourg in France. He is a very accomplished chemist who has published four books and 411 articles. Arieh Warshel, one of Martin Kaplus's teammates in multiscale computer modeling for complex chemical systems research, was once his student. Arieh Warshel is a 73-year-old Israeli-American chemist who works as a distinguished professor of chemistry at the University of Southern California. Arieh Warshel was once a student of Michael Karplus at the Weizmann Institute Israel, the same place where they all met and three chemists. Much of Arieh Warshel's research is focused on developing computer simulations for biological molecules such as simulations of enzyme catalysis and protein action, simulation of chemical reactions in solution, electrostatic energies in macromolecules, and protein folding. The complex computer modeling project has been developed since the 1960s when they met at the Weizmann Institute in Israel. They wanted to develop computer software that could simulate the chemical reaction process. They also worked together at Cambridge University in Britain on the same research. They thought that the computer could be used to simulate complex chemical processes in order to gain greater understanding about them, something difficult to do with conventional laboratory experiments .
