These have such a Kandinsky feel to them...now what is 'enantiometric'? I could look it up but I want your slant on it. Cool color scheme...design markers??

Regina Valluzzi replied:

Hi Charlie - Happy Holidays! Enantiomers are molecules with handedness, in the simplest case related by a mirror image symmetry. Most of the chemistry we know of outside of Biological contexts doesn't favor a handedness and produces a balance of enantiomers (if the molecular structure can have distinct mirror image forms). Enantiomeric excesses are significant because enatiomers are so prevalent in Biology, and are needed to create biological order - to break symmetry and move away from indistinct goo. So, what are the non-biological environments that might have created the enantiomeric excesses in prebiotic environments? People have invoked hypotheses ranging from polarized light acting on organic syntheses in interstellar matter to rotating flows in liquids here on Earth.

Yes - Art Markers. My 25 year old Prismacolors that I'd collected over several years in college. Man do they last!
