The second officer's science log aboard the USS Enterprise-D was the log utilized by Lieutenant Commander Data, the ship's second officer and science officer, to document things of a scientific nature.



Data's education of his daughter, Lal. (TNG: "The Offspring")

  • "Second officer's science log, supplemental. Training and social skills at the most elementary level has begun. Lal is progressing very slowly, but is not deterred by early setbacks. While motor coordination has improved 12%, reflexes still need to develop. Visual comprehension is especially difficult for Lal. Translating her vast data banks into recognizable applications may improve with additional transfers. She is also learning to supplement her innate android behavior with simulated Human responses... and it is interesting to note that as I observe Lal learning about her world, I share in her experience almost as though I am learning things over again."
