This graph shows the Heaviside Function.

Its value is 0 on the left (input is negative), and 1 on the right (input is positive).

This function is bigger on one side. That's what it is, a function that's unbalanced. It's often used in integral convolutions, where it acts like a weighting function in a weighted sum.

I spent years believing the name of the function references the fact that it's heavy on one side. Nope.

It's named after its inventor, Oliver Heaviside.

I can't get over this.
