At some point, the number of cases hit an inflection point, which has to do with cases going sharply up. It turns out that the smell from a fart is caused by methanthiol and other similar sulfur containing molecules, and these molecules are TINY. They vary in both size and shape, from the roughly spherical rhinovirus (the cause of the common cold; rhino means nose) of 300 in diameter, to the narrow and elongated Ebola virus which can be nearly 10,000 long! One electron volt is equivalent to about 1.6x10^-19 joules. Trevor A.
