NOBEL PRIZE IN CHEMISTRY 2013

NOBEL PRIZE IN CHEMISTRY 2013


Nobel prize
Arieh Warshel,Martin Karplus,Michael Levitt

The Nobel Prize in Chemistry 2013 was awarded jointly to Martin Karplus(Austria), Michael Levitt(SA) and Arieh Warshel(Israel) "for the development of multiscale models for complex chemical systems".


Chemists used to create models of molecules using plastic balls and sticks. Today, the modelling is carried out in computers. In the 1970s, Martin Karplus, Michael Levitt and Arieh Warshel laid the foundation for the powerful programs that are used to understand and predict chemical processes. Computer models mirroring real life have become crucial for most advances made in chemistry today.

Chemical reactions occur at lightning speed. In a fraction of a millisecond, electrons jump from one atomic nucleus to the other. Classical chemistry has a hard time keeping up; it is virtually impossible to experimentally map every little step in a chemical process. Aided by the methods now awarded with the Nobel Prize in Chemistry, scientists let computers unveil chemical processes, such as a catalyst’s purification of exhaust fumes or the photosynthesis in green leaves.
