Science First Friday , at Brooks Free Library, 739 Main St. Harwich, December 5, 12 Noon- 1 pm, will feature an illustrated presentation Creating Wave Patterns with Color Mirror Symmetries , by Al Rosenberg, a retired biophysics professor and Past President of the New England Section for American Association of Physics Teachers. 

" Nature abounds with examples of vibrations and wave behavior. Interesting designs in space are often produced when sound, light, or water waves meet and combine. With the technique of computer simulation, intriguing color images are obtained representing the oscillation patterns. Of special interest are regions where the different shapes appear reflected but the colors are interchanged," states Dr. Rosenberg, who for the 

past twelve years produced the television show "Cape Environmental Connections" on Channel 17, and is starting up a new program called "Art, Science & Everything Else". 

This brown-bag lunch discussion is free and open to the public,
