Stress. Internal forces set up in a material by the action of an external force. (Materials Handbook: An Encyclopedia for Purchasing Agents, Engineers, Executives, and Foremen, George S. Brady, McGraw-Hill, 1944)
This old leather bound book serves as an antidote to the stresses of virtuality. I couldn't resist making some tiles 4.25" tiles of the embossed images of tools on the cover: the microscope, sickle, cog, and telescope. They might make a good Father's Day gift: coasters or a wall trio for the right nook. I will try to put them up in our online boutique this weekend.
