scratching our heads (again) about rotational dynamics
#1
You know, in college I thought quantum mechanics was hard.  Pfft!  That's nothing compared to simulating rotating bodies.  Smile

High Frontier correctly simulates colonies where most of the mass is contained in one big rotating part.  However, systems with multiple big rotating parts — like two cylinders side-by-side — are not correctly simulated.

This is something we've wanted to handle correctly for a long time, and it has finally made it to the top of our to-do list.

We've just posted in a physics forum about it, but if there's anyone here who feels comfortable with kinetic energy and moments of inertia, please jump in wherever is convenient for you.  We really want to get this right!
