Science Valentines!

Whether you adore Valentine’s Day or despise it, you’ve got to love a clever valentine—especially if it’s science themed. Consider these great examples, and let your heart beat faster as you contemplate the timeless beauty of science merged with romance, as powerful and moving as the flushed mingling of fresh- and saltwater in an estuary:

Mike Siemens (Registered Geologist with the Missouri Geological Survey) was out mapping earlier this winter and came across this eroded Mesochorispira grimesi in a Burlington-Keokuk Limestone (Mississippian) outcrop. He was inspired to make a valentine from it.

This valentine was made by Anne Raymo, the aunt of Maureen Raymo (submitter, Director, Lamont-Doherty Core Repository). It is titled “Arrow of Time” and the squiggly lines are the LR04 stack (a stacked benthic d18O record of Earth’s climate for last 5.5 Ma; Lisiecki and Raymo, 2004) plotted in phase space by Jim Galasyn.
You can also see a slew of science valentines based on the microbes of Yellowstone on the Thermal Biology Institute’s site at Montana State University (thanks to Suzi Taylor for submitting them!)
Didn’t have time to submit your own? You can still share your science-themed valentine today via our Facebook page or Twitter feed (@theAGU).
