So, some governments want to attract more young girls to a science/engineering curriculum, because they think that half of the population should take part, and shape tomorrow's industries.
My tiny contribution towards this (I believe sensible) goal is the following Watt's curve, which I designed so that it resembles an enticing heart
The curve is defined in the complex plane. With Wikipedia notations, it the heart-shaped Watt's curve polar equation is:
\[{ r }^{ 2 }={ b }^{ 2 }-\left[ asin\theta +\sqrt { { c }^{ 2 }-{ a }^{ 2 }{ cos }^{ 2 }\theta } \right] \]
with
\[a=0.48\quad b=1\quad c=0.5\]
Most will probably find it cheesy. Some may even find it sexist. But I insist I meant no harm, just a small delicacy.
The Mathematica code to create this animated gif is in this github repo.
