I have this essay to write. It's 3000 words on Mass Differentiation. I also have a chance to go out tubing (going down the icy slopes of Northern Ontario in inflated tubes). As per my friend Elizabeth's suggestion, I shall try to write some of the essay, until I find out if I am going tubing tonight or not.
If any of my readers are geologists or astronomers, any tips on writing a paper on the theory of Mass Differentiation and the formation of the earth and solar system?
