The Lennard-Jones potential is a simple model that still manages to describe the essential features of interactions between simple atoms and molecules: Two interacting particles repel each other at very close distance, attract each other at moderate distance, and eventually stop interacting at infinite distance, as shown in the Figure.
The Lennard-Jones Potential is a mathematically simple model for the interaction between a pair of atoms or molecules. [3] [4] One of the most common forms is = [() ()] where ε is the depth of the potential well, σ is the finite distance at which the inter-particle potential is zero, r is the distance between the particles.

Two new studies suggest once again the importance of getting a good night's sleep for good health over a lifetime, as scientists pursue new understandings of restorative deep sleep.
Nicholas D’Agostino, 21, pleaded guilty Wednesday to second-degree murder in the caught-on-camera slaying of 20-year-old Yusef Staine, according to Newsday and court records.
Part of force field of ethane for the C-C stretching bond. In the context of chemistry, molecular physics, physical chemistry, and molecular modelling, a force field is a computational model that is used to describe the forces between atoms (or collections of atoms) within molecules or between molecules as well as in crystals.
Two days after the artist born Anthony Leonard Platt died at age 43, as confirmed by his wife Sherkita Long-Platt via a Facebook announcement, his spouse has since shared his cause of death with TMZ.
MD was originally developed in the early 1950s, following earlier successes with Monte Carlo simulations—which themselves date back to the eighteenth century, in the Buffon's needle problem for example—but was popularized for statistical mechanics at Los Alamos National Laboratory by Marshall Rosenbluth and Nicholas Metropolis in what is known today as the Metropolis–Hastings algorithm.
