I know that we aren't touching anything because atoms are repelling because electron can't touch each other. What I'm trying to figure out is texture. I think the reason we feel texture is because of the variance in atoms in a particular spot. For example a table is smooth because the atoms are about the same distance from the same distance from your hand or finger. If there is a scuff on a table then the number of atoms in that location is scraped off leading you to feel the difference in repulsion. Am I thinking about this right? If you need to use math just be aware that I haven't had calculus, but have had precalc/trig. Thank you for your help.
