Relative Movement

The most important thing you learn in Station Tech 101 is movement is relative. The first day, my instructor droned on about inertia frames and relative motion for two hours. Anyone who lasted through the lecture without falling out of his or her seat was allowed to come back the next day.

During that lecture, I was trying to fix my voice recorder, so I didn't fall asleep once. Later, while feeling naked inside an ion-loader, I happened to flash on the lecture and began to suspect I had missed something terribly important which would keep me from falling into the ring plane.

I was orbiting the station at the time. The station was orbiting Saturn. Saturn orbits the sun. The sun orbits the center of the galaxy. How far (through space) do we move each day? I'm sure someone has figured it out. It doesn't feel like we are moving at all.
