    Solving cubic or higher degree polynomials by hand

    Such equations, up to the third degree generally, may be solved by hand, but the method of solution is quite complex and involved. For equations above the third degree, unless you can come up with a factoring which brings it down to equations of the third degree or less, it is generally...

    Is Cold Fusion a Reliable Energy Source?

    In the experiments performed for the last 40 years, the muons have replaced the electrons around the deuterium ion core (ie.e. a muon around a proton and neutron nucleus). These experiments are detailed in an older Scientific American article, easily available on an online search. The muons...

    Why is sin (x+x) = sinx cosx + cosx sinx ?

    sin (x+y) = sin x cos y + cos x sin y. Simply place an "x" for the "y" in the formula. Noted: sin (2x) = 2sin x cos x.

    Linear Expansion: Why Not Volume Expansion?

    To be more precise: If the material is of a constant uniform composition, then it will expend equally in all directions. If the material is composed of different atoms oriented diversely with respect to an orthogonal set of axes, then the material is considered anisotropic, and the coefficients...

    Phase Change: What is actually going on?

    Heat is basically asynchonous vibration of molecules. If the magnitude of vibration is sufficient to break the weak bonding between molecules in the liquid state, the "VanDeWaals" bonding, then the material will assume the gaseous state. At a critical temperature, which is nonuniform...

    Is Cold Fusion a Reliable Energy Source?

    "Cold Fusion" possible in this manner: The general argument against deuterium fusion at lower temperatures is that the Columbic repulsion force is so much greater than the strong nuclear attractive force except at extremely close separation distances. Classically, high relative velocity...
