People often ask if they should use tau instead of pi, but the answer is that usually you don't need either. Most uses of those constants are because of functions that take radian parameters, which is almost always a bad idea:

Here's the first pop of Spectrum Chuckie Egg reverse engineered back to a fully assembler-able version. The code is pretty well documented; I just need to add some more stuff to the readme about how some quirky bits work. I'll update the github soon!

I have respect only for modern x86 ASICs. It's an art and the highest level of architectural skill to implement and emulate an outdated ISA with such impressive techniques. https://t.co/Dbf3ja5TWv
Books every physics student should have:
(1) The Feynman Lectures.
Nobel-winning theoretical physicist Richard Feynman asked to teach the undergraduate introductory physics course at Caltech. It was an inspirational but breakneck experience for the students.
@mollywidstrom I have the same with two others who just cannot write their correct emails. One is in New York and has debt issues, the other in South Africa and once booked a cruise.
@lisyarus Unjustified not as in "incorrect", unjustified as in "not fully explained", the usual reasons being "well the unit quaternions map directly to the SO(3) blah blah blah" justification to Group Theory that a beginner hasn't a hope of understanding.
@lisyarus It's just one of the unjustified simplifications that every quaternion introduction seems to make, that and handwaving the ijk basis as "well, it just is". Using GA and introducing rotors there are fewer "just because" things in the explanation.
