A message written in 1914 and curled into a corked bottle was scooped out of the North Atlantic last month (NatGeo). Not a love note, but a research instrument. The Glasgow School of Navigation sent 1,890 such bottles adrift, hoping to map deep ocean currents. They were weighted to float just above the ocean floor. The message inspires me to contemplate just how far our research methods have come in the last 98 years.
