    "abstract": "This is a pedagogical paper which explains some ideas in cosmology at a level\naccessible to undergraduate students. It does not use general relativity, but\nuses the ideas of Newtonian cosmology worked out by Milne and McCrea. The\ncosmological constant is also introduced within a Newtonian framework.\nFollowing standard quantization procedures the Wheeler-DeWitt equation in the\nminisuperspace approximation is derived for empty and non-empty universes.",
