How do you press a sphere flat onto a screen?
I wrote an interactive article exploring stereographic & orthographic projections; the math ancient astronomers used, now in TypeScript with draggable demos.
Part 3 of my starplot series converting a Python star charting lib to JavaScript.

Time is fundamental to understanding the position of a star in our sky.
Our clocks follow Earth’s rotation relative to the Sun. But how do we measure time relative to the stars?
In this tutorial series, I explore Sidereal Time, how to predict which stars you see, and how to build a star plot step by step, including converting the math into JavaScript for creative coding.

Today my coffee was particularly bitter.
Maybe poisoned by the silence I am surrounded by.
I know we like to talk about positive things, but isn't aiming for a better society a positive thing?
Are we scared to improve the world while knowing what is good or bad?
We should all be united on what is good and what is bad.
Your call to stay silent, your call to be complicit.
Have you ever wondered how to draw stars?
Not cute five-point shapes, but real maps of the sky above you.
I’m sharing the first article in a series explaining the concepts and formulas needed to actually draw them yourself. It started as a personal project to create a meaningful gift for friends who had just welcomed a newborn.
After a year of coding and experiments, the process is now live.

Fight the evil!
If you stay silent you’re part of it.
No pedophiles in power.
