Dividing By Zero With The ‘Facit ESA-01’

The mathematics of the ‘Facit ESA-01 mechanical calculator’; don’t divide by zero.


Infinity is not a real number. It’s a concept. In Calculus class I learned about upper bounds and lower bounds; limits. Infinity is a big deal in Maths because it’s a big deal in reality – Sort of.

Anyway, I came across one cool machine not too long ago, and it used a simple math principle to divide numbers: division is a mega-system of subtraction. A whole value, x that is the result of a number, a divided by b is the number of times that b can be subtracted from a to give 0. Sometimes it gets really close to zero but it never gets there. in other words,

(a/b) = x = [#t ] (10 - 5) ~ 0

It is this principle that the Facit ESA-01 uses to divide. And unlike modern calculators that display an error message when you try to divide a number by zero, ESA tries to commit suicide. Continue reading “Dividing By Zero With The ‘Facit ESA-01’”

Do Women Really Want Equality?

“You know what’s worse than catcalling? No one ever asking you out. Never feeling desirable. Always having to take the initiative sexually and getting rejected most of the time. One of the luxuries of being a woman is that we don’t have to ask for affirmative consent because we don’t have to take the initiative and therefore are not held responsible or accountable for anything that happens.”

Feminists would have us believe that life is so much worse for women than men, that we are weak and the “patriarchy” is against us, and therefore we deserve all sorts of programs and benefits just to be on a level playing field with men. But the plain fact is: here in the West, we have it pretty great. In many ways better than men. And if we really took a look at men’s lives, we might realize that.
