Friday Evening 7:30 - 9:00 pm:  Michael McGinnis, Santa Rosa Junior College

Perplexus Puzzle
Michael McGinnis will reveal his 35-year odyssey in the conceptualizing and development of his award-winning 3-dimensional labyrinth games known as Perplexus.  What does it take to make an abstract idea a physical reality?  When is it important to let others in on your secrets, and to rely on them to find success?

About Michael McGinnis:
Michael McGinnis is number 11 of 12 siblings, with 8 older sisters and three brothers, whereas his sisters have four brothers. Michael has ~14% more sisters than the girls do. He is an instructor of sculpture and design at Santa Rosa Junior College, and a practicing artist and exhibit designer.

Saturday 1:00 - 2:15 pm:  Frank Farris, Santa Clara University

Creating Symmetry Wallpaper Waves

You create symmetry whenever you choose to graph a sine curve.  The surprise is that every symmetric pattern can be created, or at least approximated, by similar choices.  Some know this as a maxim: "Everything is a superposition of waves."  In this talk, I'll explain how rosettes, friezes, and wallpaper patterns can be constructed by superimposing waves.  Combined with a dash of complex variables, this approach leads to a style of mathematical art that constructs patterns from photographs.  The "before" and "after" images below show an example of something that can be appreciated either for its use of groups, function spaces, and eigenvalues of the Laplacian - or appreciated simply as art.

About Frank Farris:  

Frank A. Farris served as Editor of Mathematics Magazine from 2001–2005, and again in 2008. He studied at Pomona College and then received the Ph.D. from M.I.T. in 1981. He has taught at Santa Clara University since 1984, after serving as Tamarkin Assistant Professor at Brown University. In Fall 2011, Farris visited Carleton College as Benedict Distinguished Visiting Professor. He has received the David E. Logothetti Teaching Award from SCU and the Trevor Evans Award from the MAA.

Elliptic Curves

This lecture would explain how to add points on an elliptic curve using both an algebraic and graphical approaches. This discussion would also include an exploration of patterns that occur when working with elliptic curves and modulos and prime numbers. If time allows, the applications of elliptic curves to cryptography may be discussed.  

Call For Proposals (Monterey 2015 and Tahoe 2015): 
 The schedule for the Tahoe 2015 and 2016 conference is full, but we are already looking forward to the  2016 spring conference in Tahoe.
