While the retort was certainly informative, the truth of the matter is that the feeling of being on a boat sailing past a stationary troposphere while lying on the grass and looking at the sky is not affected by the science of motion, or of the troposphere. It's a feeling, not a fact. And Nikhil, in his original essay, was simply trying to express that feeling.
It's true that clouds move faster than the observer can perceive, and that the troposphere is constantly in motion. But for most people, this understanding does not take away from the sensation of being on a boat. And, for many, this sensation actually serves to add to their enjoyment of the experience. In fact, the motion and dynamism of the clouds can be seen as a metaphor for life itself - always changing, always moving, and never quite able to be understood by one single observer.
So, while it's true that clouds and the troposphere may not be stationary, and that our perception of motion can be an illusion, this does not invalidate Nikhil's original essay in any way. He was simply trying to convey a feeling - and indeed he did so quite adeptly. UrRong. Bottom line: next time you lie on the grass and look up at the sky just remember that motion can be subjective - and enjoy the metaphorical ride!
