Abstract

We made two very steep parabolas, one in quartz and one in a water-soluble salt. We well know that our use of Grandfather's pantograph is as out of date in the Eighties as the dinosaur; but that is what we have and it is simple to set up. The results speak for themselves, as they are adequate.
