WebbAnswer (1 of 5): This is the Greek Letter Sigma. In mathematics, it is used to denote summation. For example, the summation of the numbers 1 to 5 is 15, i.e., 1+2+3+4+5 = 15. Webb9 apr. 2014 · That's what the "sigma"–the statistical significance –tells you! The higher the “-sigma” value, the less likely it is that a signal is just a random fluctuation in the background model. Remember, in simple terms, a “3-sigma” signal has only a 0.3% chance of being a background fluctuation, and a “5-sigma” signal is has just a 0.00006% chance!

WebbAlso, force and acceleration are in the same direction. The equation for Newton's second law is: \vec a = \dfrac {\Sigma\vec F} {m} = \dfrac {\vec F_\text {net}} {m} a = mΣF = mF net. We can also rearrange the equation to solve for net force: \Sigma\vec F = m\vec a ΣF = ma. Where \vec a a is acceleration, \Sigma\vec F ΣF is the net external ...
