Talking Math
============
At the maker space where I sometimes go there is a new type of activities:
every two weeks someone can present a mathematical topic.
I have prepared a presentation about cubic equation.
It includes a little story about math duels in the 16th century when
scholars would send each others some math problems to solve till the
dead-line comes.
One such person named Antonio Fior sent Tartaglia 30 problems. All of
them cubic equation. For Tartaglia it was easy peasy
An article about them equation can be found at https://pnqk.me/gv6h6f
I hope my presentation will be accepted, and the other participants can
learn about Panquake, with which I shorten links. I've learned about that
shortener from https://firewallsdontstopdragons.com . The shortener creates
links without tracking components in addition to archived pages.
Maybe, I can talk about creating math object in LibreOffice.

So, I am going to talk about avoiding trial-and-error due to extraneous
solutions created by cubing both sides of an equation.
In addition, there is the conclusion that a system with real coefficients
and without non-real solution you can hide the use of comples numbers and
use trigonometry. That way you could win math duels back in the 16th century
when you were not supposed to use complex numbers.

And I find math by far more interesting than spending times with my folks
talking about the weather or the war or other topic I don't remember getting
a B.Sc to talk about.
