The John Henry moment
Old technology triumphant
A mathematics teacher is not much like a nineteenth-century railroad worker–but there are parallels. Our consultant who tutors High School math and science continues to learn from it; sometimes, his students do also.
Smartphones by campfire light
An incongruity of technologies
One of our consultants has an interesting device for camping or possibly a disaster situation. On closer examination it appeared to us that it hadn’t been quite thought through. Then we examined it more closely still.

Our tutoring consultant continues to gain insights from his students.
