Yet through their mutual interactions, the electrons and nuclei can behave in radically different ways than they would were they isolated in vacuum. I'll discuss one particularly dramatic instance of this kind of emergent behavior in the thinnest knownnnmaterial: graphene. Graphene is a single")

_relativistic-mass-and-energy.webp "In this video the concept of rest mass or proper mass is developed. Like length and time, mass is relative. The famous E = mc equation is also used to measure total energy as measured in a given reference frame. Ignoring any potential energy, the total energy of an object is broken down into its rest energy and kinetic energy and for a charged particle in an accelerator, this kinetic energy may be predicted if the accelerating potential difference is known. This video will support your learnin")
