The Iridium System
Several Low-Earth-Orbit (LEO) networks were proposed, but only one got off the ground: the Iridium system. The original Iridium proposal called for a "constellation" of 77 satellites, which gave the plan its name: the element iridium has atomic number 77, meaning that an iridium atom has 77 orbiting electrons. Before the satellites were launched, the constellation was scaled back to 66 active satellites, but no one wanted to change the name to Dysprosium.

The Pleasure of Observing
Abbreviation
I generally do not like to abbreviate behavioral notes. An important detail may be ignored or considered irrelevant and discarded because it lacks a discrete category on the list. It is often an anecdotal event that offers special insight.
Beyond dry facts
If one has a personal knowledge of the individual animals being studied, observations in field notes cease to be impersonal, and an observer’s empathy can lead beyond dry facts to better intuition and insight.
A study should persist
Since we cannot interview the subject, we can only infer the past from the present. Ideally, a study should persist for at least the life span of an animal.
