Last week, I said that unlearning will turn your world upside down. To make this point more succinctly, I would like to direct your attention to the photo on the right. It is a common view of earth as seen from space.
I went on Google today to try to find a similar image only from a different perspective — upside down. Now, if you think about this for a moment, it shouldn't have hard because there is no "upside down" in outer space — things are only relative according to your orientation.
Surprisingly, I could find no photos from this "opposite" perspective. One important take-a-way from this little lesson is that conventional wisdom has a very powerful hold over how we see things, including our planet.
