You could slide through the physics final with this device, at one time.
This is the device used to put humans on the Moon.
Have you ever used one?
It’s a slide rule. Nice story about Art Hunt’s kids listening to tales from the olden days, and bringing back a little piece of the olden days for him. He now claims to be ready for a power outage at his lab.
How does anyone understand a logarithmic scale anymore without a slide rule? Does anyone make good slide rules anymore?

Retired teacher of law, economics, history, AP government, psychology and science. Former speechwriter, press guy and legislative aide in U.S. Senate. Former Department of Education. Former airline real estate, telecom towers, Big 6 (that old!) consultant. Lab and field research in air pollution control. My blog, Millard Fillmore's Bathtub, is a continuing experiment to test how to use blogs to improve and speed up learning processes for students, perhaps by making some of the courses actually interesting. It is a blog for teachers, to see if we can use blogs. It is for people interested in social studies and social studies education, to see if we can learn to get it right. It's a blog for science fans, to promote good science and good science policy. It's a blog for people interested in good government and how to achieve it. BS in Mass Communication, University of Utah Graduate study in Rhetoric and Speech Communication, University of Arizona JD from the National Law Center, George Washington University
