sum of the squares of the reciprocals of this function evaluated at the nonnegative integers is equal to the modified Bessel function of the first kind at x=2. The Leviathan Number is found by evaluating this function at 10 to the 666th power. The rising type can be represented with the Pochhammer Symbol. Wilson's Theorem states that this function of any prime minus 1 is also congruent to -1 modulo that prime. Legendre's theorem provides a corollary to determine the number of (*) trailing zeroes of this function evaluated at nonnegative integers. When this function is evaluated at large numbers, Stirling's approximation is used. The gamma function extends this function to all complex numbers other than negative integers. For 10 points, name this function that, for positive integers n, is the product from 1 to n, and which is represented by an exclamation point.
Science

Erwin Finlay-Freundlich proposed one explanation for this phenomenon that claimed its strength should be proportional to the radiation density. A version of this phenomenon in the CMB is known as the Sachs-Wolfe effect, while the quantity that describes the strength of this effect has a value of about 1100 for the surface of last scattering. One version of this effect was measured using the Mossbauer effect in an experiment by Pound and Rebka, and the magnitude of this effect is usually denoted "z. " For 10 points, name this phenomenon, which can be caused by gravity or the Doppler effect, in which the wavelength of an object's light appears longer to an observer.
