Well, one dream, to be precise. Flying dreams are famously pleasant experiences. It’s been a long time since I had one. In a recent dream I found myself in a location where people could fly off the top of a hill, coasting above the landscape down toward the valley. But I was curious, and I had to ask someone why this is possible. She explained to me that it had to do with the gentle slope of the hill, and that the rate of falling produced just enough impulse to keep you above the ground. Which seemed convincing at first, but then I started thinking about the acceleration that would entail, and it seemed we’d end up crashing toward the valley floor with a horrendous speed.
And after I’d thought that through the flying, which had been so effortless before, became impossible. At least for me.
Let no one say that scientific education can be had without costs…
Fortunately, I do not dream, or at least have no recollection when I wake up.
