A Match Made in Math-Heaven
If series are peanut butter, then integrals are jelly. You could put one or the other on a couple slices of bread and have a satisfying sandwich. You could also put them both together and have a

general relativity
The theory states that the quality of the definition given is inversely proportional to the length of the definition.
Thus, the longer the definition, the crapper it is.
Through the theory of general relativity, we can deduce that the top definition is not worth reading.
