So the realistic scenario would be, you reach out in curiosity to touch the grain of sand. Your fingertip gets 1 cm away, and you feel like it's being gently pulled on. You bring it half a centimeter closer, hrm, more of a pull, then you get to 1-2 mm away, and it suddenly feels like someone yanked on your nail as your finger suddenly snaps to the grain of sand (much like two closely spaced magnets suddenly snap into one another).
At that very instant, it feels like someone has grabbed a square millimeter of your fingertip with pliers, so you yank your arm back and that tiny little area on your fingertip is torn off in the process. Your fingertip now has a little crater on it, about 1mm in diameter, and looks like you had a teeny little wart removed.
This blog exists purely as a place for me to dump random links and thoughts I have rather than emailing them to my friends. It'll have large amounts of inside jokes. Also there will probably be times when I write "you" or refer to an email. Just pretend that you are reading an email to you. If you don't know me you likely won't find anything here interesting. If you do know me you also will not find anything here interesting.
