The Shape of Melting in Two Dimensions

https://vimeo.com/201923842 Snow falls in winter and melts in spring, but what drives the phase change in between? Although melting is a familiar phenomenon encountered in everyday life, playing a part in many industrial and commercial processes, much remains to be discovered about this transformation at a fundamental level. In 2015,…

Fundamental Fission Modeling Finds a Foothold

https://vimeo.com/176316108 While trying to fatten the atom in 1938, German chemist Otto Hahn accidentally split it instead. This surprising discovery put modern science on the fast track to the atomic age and to the realization of technologies with profound potential for great harm or great help. Although scientific experts, thought…
