Hi, I was wondering what Lorenz Factors are. Can someone give me a simple definition?

After successfully solving tons of problems about factoring polynomials I've buit up quite a confidence in myself. But it did not last long when I stumbled upon these problems Factor $3x^3-13x^2+23x-21$ $ 6x^3-2x^2-13x-6$ None of the techniques I knew were able to help me solve these...

My question is fairly simple, but I'm having a hard time finding the answer. A guitar body dampens the vibration of a guitar string to some degree by contorting slightly as the string oscillates, and then producing sound waves and heat in turn. My question is; is it the mass the of the...

I have drawn five connected diagrams that arise in ##\phi^4## theory. I was wondering if the symmetry factors I have for each of them are correct and if I have missed any graphs.
