In our experiment, a constant speed stage pulls a slider which rests on a vertical bed of circular photoelastic… symposium on soft matter forefronts science and technology of advanced materials and interfaces (stami)college of sciences georgia tech spring 2018 From Kathryn Gentilello 10 Months ago 19 views 0 name Aghil Abed Zadeh Date 04/20/2018
40:50 Exploiting disorder - Sid Nagel Exploiting disorder - Sid Nagel	Exploiting disorder - Sid Nagel We are taught to understand solids by considering ideal crystals. This approach becomes untenable as the amount of disorder increases; for a glass with no well-defined long-range order, a crystal is… symposium on soft matter forefronts science and technology of advanced materials and interfaces (stami)college of sciences georgia tech spring 2018 From Kathryn Gentilello 10 Months ago 12 views 0 name Sid Nagel Date 04/20/2018
