The best scientific meetings that I have attended are those on Atmospheric Optics, sometimes called Light and Color in Nature. Everyone is an aficionado, friendly, and the meetings are never attended by any representative of a funding agency. Thus, their tone is one of unadulterated joy. The third day of the 2007 meeting, organized by Joe Shaw had no talks, but instead, a trip to Yellowstone Park. On the bus there, I sat with Joe and he asked me if I would write a poem for this meeting as I had in 2004. I hadn’t thought of it, and decided that I could not write another roast. I have become interested in what has motivated people to become concerned with preserving the natural environment in the wake of Al Gore’s influential book and movie, “An Inconvenient Truth”. It turns out that most Prime Movers in saving the planet (such as John Muir and Rachel Carson) were first lovers of the beauty of nature who, later in life grew alarmed that our planet was being sadly abused. All who love the beauty of nature, and point out that beauty to others may help save the planet and enrich lives. And thus I discovered one more beautiful aspect of the lives and importance of my colleagues and friends at the Optics Meetings. Light and Color in Nature Stanley David Gedzelman 30 June – 01 July 2007 Theme We come to Light and Color in Nature meetings every 3 years from a world that has many troubles. During the intervening time, mostly alone we trudge on keeping and perhaps spreading the faith, which may well help lives of others. Then at the meeting we join forces, minds, intuitions and sightings and are renewed in a common spirit. Finally, we return to the world refreshed with renewed vigor and impact. Who will know what lives we and other similar aficionados save and what wars we prevent through our love. We all are creatures so complex Propelled by drives that make us wrecks That nothing e’er can guarantee To cleanse our souls and set us free Still love of beauty gives us pause To follow any evil cause For any form of light is love That links us with angels above So, shedding light on others’ vision Is our crucial, sacred mission We each see with unaided eyes Optical wonders in the skies Rainbows, halos, c’ronas, glories We root out their secret stories Then turn our gaze to ponds below Or on the myriad shapes of snow So stay enthralled as Wordsworth’s child With vision pure and undefiled Yet when alone we do get tired And sorely needs be reinspired. So each 3 years we reconverge To satisfy the basic urge To share our findings and renew Our spirits with each others’ view Like DNA our souls unwind So that our insights are combined Then revived with souls uncurled We head out for the sorry world Spreading nature’s color and light. And lo, we help it set aright.
