The absence of defects inhibits melting, making the crystal much more stable, and it reduces the energy difference between crystal and liquid. Thus, the\u0026nbsp;melting transition acquires a distinct second-order character, even though it is strictly a first-order transition.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThis form of melting was first proposed by the German physicist Max Born nearly 80 years ago. It is only now that its study can be carried out.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EAbout the Speaker\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EDavid Weitz \u0026nbsp;is the Mallinckrodt Professor of Physics and Applied Physics at Harvard University.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAfter receiving is Ph.D. in physics from Harvard University, he joined Exxon Research and Engineering Company, where he worked for nearly 18 years.

Polymer solutions and gels, colloidal suspensions, liquid crystals, aerosols, granular matter, emulsions,\u0026nbsp; and foams are all examples of soft materials.
