A sphere moving down the surface of a static sphere and a simple phase diagram
A small sphere placed on the top of a big static frictionless sphere, slips until it leaves the surface at an angle θl=-12/3. On the other extreme, if the surface of the big sphere has…

Transversality of Electromagnetic Waves in the Calculus-Based Introductory Physics Course
Introductory calculus-based physics textbooks state that electromagnetic waves are transverse and list many of their properties, but most such textbooks do not bring forth arguments why this is so.…
