My answer was migrated from English.stackexchange.com.
The equation in it looked bad then, but it was edited and it looks worse now. The "proportional to" sign (which has a similar shape to the Greek letter alpha) has a v "del" symbol instead.
Is there a formatting language subset that might fix it? How can I get this to look more like the equation at https://en.wikipedia.org/wiki/Herdan%27s_law ?
