"At first it was thought that the uncleft was a hard thing that could be split no further; hence the name. Now we know it is made up of lesser motes. There is a heavy kernel with a forward bernstonish lading, and around it one or more light motes with backward ladings. The least uncleft is that of ordinary waterstuff. Its kernel is a lone forwardladen mote called a firstbit. Outside it is a backwardladen mote called a bernstonebit. The firstbit has a heaviness about 1840-fold that of the bernstonebit. Early worldken folk thought bernstonebits swing around the kernel like the earth around the sun, but now we understand they are more like waves or clouds."
