The song's original version was included on several compilations, including the 2001 albums "The Source Hip Hop Music Awards 2001", "Pure Dance 2001", "Hip Hop Soul Party: Episode V", and 2008's "15 of the Best Urban Classics". "How Many Licks?" is a three-minute and 52-second hip hop song that uses a sample from the theme song of the television series "Knight Rider".

Cross section (physics) to the sum of cross sections over all events. The differential cross section is extremely useful quantity in many fields of physics, as measuring it can reveal a great amount of information about the internal structure of the target particles. For example, the differential cross section of Rutherford scattering provided strong evidence for the existence of the atomic nucleus. Instead of the solid angle, the momentum transfer may be used as the independent variable of differential cross sections. Differential cross sections in inelastic scattering contain resonance peaks that indicate the creation of metastable states and contain information about their energy
