“Good science requires good record keeping.”¹
The laboratory notebook has changed little over hundreds of years. Part journal, part scrapbook, it is a record of both what a researcher thinks and what she does. It documents her day-to-day hypotheses, experiments, observations, analyses, and conclusions. Think of Leonardo da Vinci’s sketches of a flying machine or Darwin’s detailed field notes from his voyage on the Beagle. In today’s modern laboratories, researchers use the same kind of bound paper notebook to document their work.
