# Scientology nuttiness part dy/dx: calculus

I thought this was a joke at first, but it appears to be true: the founder of \$cientology, L. Ron Hubbard, thought calculus didn’t work.

Now, I know a lot of my readers may not like calculus, and may even hate calculus, but to say it’s wrong is, well, lunacy. Of course it works! Trying to come up with ways it works in everyday life is like drinking from a firehouse, but let me just make a list based on astronomy.

Calculus is used in:

1: determining planetary positions

2: sending spacecraft to those planets (and there are a zillion ways it’s used in this, from calculating how much fuel you use to knowing how much air the astronauts need in space)

3: determining how stars are born, live and die (something we understand pretty well)

4: calculating the tidal force of the Moon (and other planets and moons on each other)

5: calculating the gravitational field of an object

6: understanding basically anything that changes

7: understanding anything that moves

8: Newton’s three laws (and his Law of Gravitation) which are the foundation of classical mechanics

9: all of quantum mechanics too, for that matter
