The G?mb?c shape

Doug Mcnutt
The Gömböc shape
<http://www.maplesoft.com/company/publications/articles/view.aspx?SID=146065&p=TC-3444>

I am very interested in the details of  "Binary .STL files & point 'equality'". The difference between 64 and 32 bit floats and the problem of least count dimensions and integer arithmetic may just be more interesting than you think. There just may be a link between Schrödinger's equation, Einstein's emergy-momentum tensor, and allowed vertex positions. Are there quantum rules that apply to choices of vertices? It's just possible that those particle size questions that were brought up have meaning when it comes to describing orbits and clouds made by electrons in an atom or a silicon crystal.

I'll have a look at creating a Gömböc using openscad to create an STL file but I would love to see someone beat me to it. My old version of Maple never heard of STL.

Weebles wobble but they don't fall down!!!

I have now exhausted my Gömböc expertise.

think that the problem is also dew to trying to use base linear scale  to objects that are based on curves and circular motion , as if pi should be a rational number

Weebles aren't homogeneous. They have a weight in their back side.
