# There is only 1 type of calculus

An amazing idea with a few names – the ‘calculus of logic’ or the ‘calculus of probability’ – but really there is only one Calculus, despite the idea coming from the brains of 2 different people: Isaac Newton and Gottfried Leibniz who pioneered it in the 17th century.

However, they came upon this idea independently. Which version was best? Up to you, but keep in mind that Newton was rude to people, put numerous folk to death when he ran the royal mint, and died a virgin. Go figure

Wow, sounds like they need them too. According to the same article, “Some years, there are literally no women in Math 55”. I wonder if mathematicians have the same number of kids (on average) as the rest of us?

What is the volume of a disk with radius z and height a?

Answer:

Pi z z a!

From wiki “It has two major branches, differential calculus and integral calculus; the former concerns instantaneous rates of change, and the slopes of curves, while integral calculus concerns accumulation of quantities, and areas under or between curves.”

Two branches, or 2 types of Calculus? Not sure if this means there are 2 Calculuses? Calculii etc etc ha.

“Calculus is the mathematics of change and motion. There are two types, differential calculus, finding the rate of change of a function and, integral calculus, finding the function when its rate of change is given.

“Why is Calc 1 called “Single variable calculus” and why is Calc 3 called “Multivariable Calculus”

Idea:There is only 1 type of calculusLink:https://nautil.us/issue/89/the-dark-side/w...The problem may be to do with the fact that mathematicians have been allowed to name things. I guess they felt they were qualified to do so because they saw physicist name things and decide to have a bash at it themselves.

Fortunately, physicists trump chemists and use chemistry words like “metal” to mean any element above helium. Why not? They got away with it and it’s their world too.

Let’s just hope those clever fundamentals mathematicians don’t start trumping the physicists with language. After all, this is the “real” world we are dealing with here. (joke)
