Circle Division

[Stargazer]

Those are nice calipers! How old are they?...

[Stargazer]

Don't mean to be disagreeable but he answer is yes. The Peano axioms and Zermelo-Frankel set theory provide a solid foundation for basic arithmetic. Even...

[Stargazer]

Yes. The Peano axioms work just fine to establish a basis for arithmetic....

[Stargazer]

This is a great question that has deeper implications for mathematics education than first meets the eye. The standard view in mathematics, both mathematical...

Hey, just wanted to send you a quick note thanking you for all of your thoughtful contributions to my threads.

What kind of machine work...

[Stargazer]

Yes, there is. In 4D spacetime, a straight line generalizes to a geodesic. At very short distances like in our shops or labs, Minkowski space is virtually...

[Stargazer]

I gotta tell you, I find the whole thing captivating. I'm studying math at UB and it's a big topic in mathematical philosophy how math is a real thing...

[Stargazer]

It masterful book. Thanks again for recommending it. I spent the entire weekend on the circle division section. When I googled the subject, I came across...

[Stargazer]

If you were "starting from scratch" (conceptually, not necessarly in real life) how would you relate circle division to making more precise...

[Stargazer]

It might not be fundamental, but it's still pretty cool and practical.

What is the main purpose of circle division if not for measuremen...

[Stargazer]

I downloaded a copy of "Foundations of Mechanical Accuracy" that you guys recommended in my other threat. Wow! What a fascinating book and a...

[Stargazer]

It is! You're right about the feeling developing faster than you'd think. I thought it would take months. I was going to look at some used tools for sale...

[Stargazer]

Dumb question: Is the 64th scale on a combination square accurate enough for this? I was practicing with the magnification and calipers and "cutting"...

[Stargazer]

Awesome! I ordered a copy of the book Joel recommended. Should be here this weekend. This subject has really sparked my interest....

[Stargazer]

I'm going to give it a shot. I'm pretty patient. It sounds like fun....

[Stargazer]

Nickel City - you wouldn't happen to be in Buffalo too, would you?!

What really has me stuck - maybe I'm overthinking this is - is how "tolerances"...

[Stargazer]

I understand now. I'm still at the point where I'm just learning and having fun with the tools, not getting too frustrated. Learning about this stuff...

[Stargazer]

I'm new to machining and still learning about how the basic tools work and measurements are taken. I'm curious about "spring calipers". I read...
