Reports from Other Journals: The Physics Teacher
The Physics Teacher: The Four States of Matter—Solid, Squishy, Liquid, and Gas
Roy W. Clark
Middle Tennessee State University, Murfreesboro, TN 37132
Cover
April 2007
Vol. 84 No. 4
p. 588
Abstract
The featured article offers several demonstrations of substances that seem to be neither solid nor liquid, but somewhere in between. The authors suggest laboratory experiments that can be performed by beginning physics students, and suggest theoretical explanations for the strange viscosity behaviors. The subject is chemistry much more than physics, and it may require chemistry textbook authors to rethink the popular definitions of physical and chemical change. This reviewer then comments on the historical origins of squishiness, and on its unfortunate neglect, in their author's opinion, by general chemistry texts. The subject is properly called rheology, and is of considerable significance to industrial chemists.
