  1. The order within the categories are right, but I think A should be last, D second to last, B first, and C second, but only because I'm applying human behaviour here; we tend to go to sleep after we do our daily activities. I understand cats have a very leisurely life and do whatever they want.
  2. I have a sweater that is 40% acrylic and 60% polyester. It looks as if it was knitted, i.e. it has little tiny holes in between the threads (see pictures). I'm shortsighted, and when I take off my glasses and put the sweater in front of the eyes, I can see much more clearly than I can without glasses. It's not as clear as when I do have my glasses, and the threads get in the way, but there is a marked difference. I'm guessing light gets diverged like going through a corrective lens, but all it does here is pass through small, physical holes. Why does my vision get clearer when I wear my sweater in front of my eyes?
  3. Someone on Yahoo Answers who claims (s)he has a physics background wrote that solidity is only an illusion, because there are so many atoms, and we would see that atoms are mostly space at the sub-nanometric scale. (S)he also wrote that there is 'no solid, no liquid and no gas. There are only atoms and atoms are mostly empty space with nucleus of protons and neutrons and electron clouds.' It's just that I thought that the bonds between atoms/molecules determine whether they are solids, liquids, or gases: independent atoms/molecules with no bonds for gases, Van der Waals or weaker interactions to keep atoms/molecules together for liquids, and stronger, cohesive bonds in solids. Who's right?
