Archer joins us again in the Tangent Cube to give a slideshow presentation about precision. What does it mean to do precision work? How do you get a perfectly straight edge, or a perfectly flat surface? How do we do it in the modern day, and what does that mean for highly precise work done in ancient times? This was an awesome conversation. We really recommend watching the youtube video so you can see the slides. Enjoy!
