What does it mean (in physics) to say that a quantity is conserved? Explain. The first law of thermodynamics and the conservation of energy, as discussed in Conservation of Energy, are clearly related. How do they differ in the types of energy considered?
” In many physics textbooks, the student is usually provided with the equations for a charge and is told how the charges are distributed throughout the universe. Once the student has been taught about the concept of a charge, he can start to apply it to situations that are practical...

AnN-type semiconductoris one that carries current in the form of negatively-charged electrons. This is very similar to conduction of current in a wire. AP-type semiconductoris one that carries current predominantly as electron deficiencies called holes. A hole has a positive electric charge. This...
that decays in the variable; one can then hope to do a suitable stability (or instability) analysis of this soliton to perturb it to a blowup solution, as there are many results of this type for other equations that one could use as a model. The energy conservation law does constrain to...
