A recent article in New Scientist (page 60 of Oct 6-12, 2007 issue) claims that Oliver Heaviside invented it 30 years before Dirac. I have not been able to confirm this claim any other place, but have not looked that hard.

What is the laplace transform of a unit step function?
a pulse (dirac's delta).
How do you plot Dirac function in MATLAB?
To plot each value of a vector as a dirac impulse, try stem instead of plot.
What does delta mean in maths?
There are many meanings. The most common one is "change in". So delta x is the change in x. This form is often used in calculus where it means very small changes in x. But there is also the Dirac delta function, a fundamental mathematical underpinning for quantum physics. A delta can also be a quadrilateral which is otherwise known as an arrowhead.
What does the derivative of a function mean?
The derivative of a function is another function that represents the slope of the first function, slope being the limit of delta y over delta x at any two points x1,y1 and x2,y2 on the graph of the function as delta x approaches zero.
What is the delta function?
a2 +/- b
