Hello! I checked the calendar, and it is Monday. I checked my passport and my name is Colin. I checked my job description and I’m a mathematician. And, as always, I’m here to offer whatever assistance I can.

So, what can I help you with this week?

Right now, I’m putting the finishing touches on a biomechanics project to find the angles between the various parts of a leg as it exercises. I had hoped to use quaternions, but sadly Euler angles were the order of the day. It was still fun!

@icecolbeveridge "sadly Euler angles were the order of the day" - and you were able to show that a situation like gimbal lock is not a concern in this situation?

@tpfto I'm not 100% sure, but my suspicion is that someone would need unusually flexible joints for it to be a concern ;-)
