    Graduate What 'Thing' Does the 'Work' in a Constant Universe of Mass and Energy?

    Mass and energy Mass is a bunch of atoms, and inside atoms are particles. Mass is a generalization of these particles that we physicists are constantly trying to understand better and in more detail. These particles can also behave like light waves. This is the ultimate question; do these...

    Undergrad Why Does Cramer's Rule Give Different Determinants for the Same Matrix?

    Omg! Sorry... I calculated incorrectly by forgetting a negative. My mistake was 1(6-12) It should have been 1(6-(-12)) Thanks

    Undergrad Why Does Cramer's Rule Give Different Determinants for the Same Matrix?

    This is very weird, but I found an inconsistency in the application of Cramer's Rule for a 3x3 simple linear matrix. 1x + 1y + 0z = 3 -1x + 3y + 4z = -3 0x + 4y + 3z = 2 Dz = 1 1 3 -1 3 -3 0 4 2 If you take the determinant across the first row To find Dz, I constantly get...
