    Quaternions And Complex Numbers

    Hi Kambiz, one picture/representation of quaternions (i,j,k) you can have is of them being traceless hermitian 2*2 matrices over complex numbers. (Then exponentiating combinations of them, you generate 2*2 unitary matrices, which we can map to ordinary rotations in 3 dimensions - in...

    What If the Speed of Light Were No Longer Constant?

    Theories with varying light speed have been worked on recently by theoretical physicists such as Joao Magueijo (Imperial, London) (who published a popular science book called Faster than the Speed of Light) and John Barrow (Cambridge) as well as Lee Smolin (Perimeter Institute). I attended a...

    Gravity constant G = 3(H^2)/[4pi(e^3)ρ].

    "Suppose that there are X rival explanations of gravity, each proven to predict the correct result. Then the acceleration of gravity on the surface of the planet Earth will be 9.8X ms-2. The success of the single mathematical proof above therefore disproves the possibility of any alternative...
