on liquid argon studied a system of 864 argon
Argon
Argon is a chemical element represented by the symbol Ar. Argon has atomic number 18 and is the third element in group 18 of the periodic table . Argon is the third most common gas in the Earth's atmosphere, at 0.93%, making it more common than carbon dioxide...

 atoms on a CDC 3600 computer, utilizing a Lennard-Jones potential
Lennard-Jones potential
The Lennard-Jones potential is a mathematically simple model that approximates the interaction between a pair of neutral atoms or molecules. A form of the potential was first proposed in 1924 by John Lennard-Jones...

. His algorithms still form the basis for many codes written today. Moreover, he worked on a wide variety of problems, such as the microcanonical ensemble
Microcanonical ensemble
In statistical physics, the microcanonical ensemble is a theoretical tool used to describe the thermodynamic properties of an isolated system. In such a system, the possible macrostates of the system all have the same energy and the probability for the system to be in any given microstate is the same...

 approach to lattice gauge theory
Lattice gauge theory
In physics, lattice gauge theory is the study of gauge theories on a spacetime that has been discretized into a lattice. Gauge theories are important in particle physics, and include the prevailing theories of elementary particles: quantum electrodynamics, quantum chromodynamics and the Standard...

Aneesur Rahman was a native of Hyderabad, India. He earned his undergraduate degree in physics and mathematics from Cambridge University in England and his Ph.D. in theoretical physics from Louvain University in Belgium. In 1960, Dr. Rahman began a 25-year tenure as a physicist at the Argonne National Laboratory (Argonne, Ill.). In 1985, Dr. Rahman joined the faculty at the University of Minnesota as a professor of physics and fellow at the Supercomputer Institute

Dr. Rahman is known as the father of molecular dynamics
Molecular dynamics
Molecular dynamics is a computer simulation of physical movements of atoms and molecules. The atoms and molecules are allowed to interact for a period of time, giving a view of the motion of the atoms...
