Use the recommended maintenance schedule from the manufacturer of your car. Do yourself the most that you can, you will learn more about... -
Spinnor replied to the thread Undergrad Edge of Brillouin zone,1D crystal, graphene, standing wave, band gap.That is one of the first things you learn when you study the physics of graphene. A standing wave in graphene is a bit more complicated... -

The following is taken from Bjorken and Drell, Relativistic Quantum Mechanics (1964), pp. 5-6: So the problem with the Klein-Gordon... -
Spinnor reacted to DaveC426913's post in the thread Construction How do I fix a hedgehog enclosure that keeps getting too humid with
Like.
By the way, do you have a hygrometer in there, to ensure you are tracking the actual humidity? They're about 10 bucks.
