Writing an equation for a circle given endpoints of diameter

With the exception of kettledrums and tympani, drums do not make single identifiable notes when played. Drums actually make several different notes simultaneously. This third step is the secret sauce that makes the difference between a drum that measures like it should be in tune, and one that sounds like it is in tune.

It contains links to the contemporary mathematical and scientific literature. I describe some of the chance events in and that led to my three-year immersion in this study, in which I was guided by both mathematics and physical experimentation.

I benefited greatly from discussions with several eminent mathematicians, some of whom appear in photos below, but especially useful in my study of the geometry of periodic structures were the two books 'Third Dimension in Chemistry', by A.

Wells and 'Regular Polytopes', by H. I owe special thanks to the architect Peter Pearcewho in demonstrated for me his concept of saddle polyhedron. Two months later, I had the good luck to be visited by the geometer Norman Johnson, who had just completed his mathematics PhD under Prof.

Coxeter at the University of Toronto.

Norman told me about Coxeter's paper on regular skew polytopes Proc. Van Attawho was the associate director. Fashioning special tools for the fabrication of plastic models of minimal surfaces was just one of several tasks he performed with unfailing skill and ingenuity.

I am enormously indebted to all of these people! In SeptemberI began a collaboration with Ken Brakkewho makes precise mathematical models of minimal surfaces with Surface Evolverhis powerful interactive program.

Some results of our joint work are displayed at Triply periodic minimal surfaceswhich is one of Ken's many fascinating web sites.

I pay special attention here to the gyroid minimal surface, G. The evidence for my claim that the gyroid is embedded included a computer-generated movie of Bonnet bending of the surface and also a physical demonstration of such bending, using thin plastic models of the surface.

The stereoscopic version of the movie was subsequently lost, but a non-stereoscopic version that did survive is included in this videostarting at about 3m35s after the beginning. If you view these frames stereoscopically, you may see at least a suggestion of the self-intersections that occur at bending angles different from those for D, G, and P.

Eventually the gyroid was rigorously proved to be free of self-intersections by Karsten Grosse-Brauckmann and Meinhard Wohlgemuth, in their article, 'The gyroid is embedded and has constant mean curvature companions', Calc. Partial Differential Equations 4no.

The Wikipedia entry for the gyroid mentions some of its currently recognized 'applications'. One of the first published examples of such an application describes how the gyroid serves as a template for self-assembled periodic surfaces separating two interpenetrating regions of matter.

Additional examples of applications continue to be reported, and in the future I expect to add links here to some of them. Eversion of the Laves graph The Laves graph is triply-periodic on a bcc lattice and chiral. It is of interest for a variety of reasons, not least because a left- and right-handed pair of these graphs an enantiomorphic pair are the skeletal graphs of the two intertwined labyrinths of the gyroida triply-periodic minimal surface or TPMS cf.

Because the Laves graph is one of the rare examples of a triply-periodic.Writing the Equation of a Circle Given Endpoints of a Diameter Analyzing Equations of Circles Ellipse: Equations that you need to know.
