When the sky turns green, it is a good idea to go to the basement, or to some other protected place in the house. I learned that from experience. Or, really, from the experience of my first wife, who had grown up in a small town (rather than a city) and was more nature-wise than me.
Why is that? How does that work? I don't know. But a green sky means a tornado is likely to form. In the case I am remembering, it took the roof off of a school a couple blocks away, right up into the air, and then set it down again.
The point that is interesting to me, and that came up in our early morning coffee group the other day, is that so much knowledge is like that, just bits and bytes. Some of it is conceptual, and some of it is physical (like how to sink a free throw, how to ride a bike).
The issue is that you can have a heck of a lot of knowledge, you can know a lot, but it doesn't automatically or necessarily add up to anything coherent. It doesn't create an overall picture, a meaningful world view.
And then of course there are perspectives that start the other way, with the heavens as it were. There is God, God created the the earth, and man in his image, etc. That's a "big picture" perspective, but it doesn't tell you to hide in the basement when the sky turns green, or how to sink a free throw.
Really, human knowledge is pretty patchy. Certainly the knowledge that a individual has is pretty patchy. And actually, I don't think that most people try very hard to do anything about it, and I don't think schools help very much with that, either.
