Doi published a short but fascinating piece in titled: “On the Concept of ‘Softness’” in The Journal of the Physical Society of Japan (Vol. 90, No. 10). He re-examines the definition of soft matter beyond the traditional “thermal energy ~ kT” picture, discussing “mechanical softness” (low elastic modulus) and “geometric softness” (large shape fluctuations). It’s a thought-provoking 4-page piece that serves as a meta-reflection on his own textbook. "Introduction to Soft Matter Physics" The most likely
What do Jell-O, liquid crystal smartphone screens, and the biological tissue in your own body have in common? In the world of physics, they are all "soft matter"—materials that are easily deformed by thermal fluctuations and external forces. 90, No
