Post thread
Join expert classical physics discussion on the principles developed before the rise of relativity and quantum mechanics. Including mechanics, electrodynamics, thermodynamics, optics.

Mechanics

I Is calling fictitious forces "not real" just about terminology?

Optics

I How do I stretch a laser from a beam into a sheet?

Thermodynamics

I What thermal cycle would describe the action of a candle carousel?

Electromagnetism

A Reflections at the source point of a transmission line
