On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs." --San Antonio Express-News
Posting will be light today, as I am joining University of Arizona PhD student Sarah Trube and several other Arizona cavers on a cave trip to collect water samples in a southern Arizona cave. This is in connection with research Sarah is doing to analyze the chemistry of cave dripwater and how it leads to the formation of cave speleothems. Moreover, she is tracking water flow and attempting to link it to climate and weather variations over time.
I noticed Sarah’s water collection equipment on my first Tucson-area cave trip back last January. In one case she had attached a tube to the bottom of a stalactite which fed the dripwater into a bottle. In another case she placed glass plates on top of stalagmites to allow the dripwater to drip onto the plate and then evaporate. Last month I joined her on one of her collection trips, where she gathered glass plates for later analysis in the lab. Though the plates had not been in cave more than a few months, you could easily see a thin layer of calcite deposit on their surface.
Below the fold is an image of Sarah gathering dripwater during an earlier trip.
