know different state values so by default if we you know get random stuff presented to us we want the embeddings as in a field two different situations to be far apart so that's what this law is is saying we want embeddings to be far apart but in all you do is play the embedding is far apart well then that's not enough to get any structure so then the next loss here says that four consecutive times the position state variables should be close it also says that between time T and t minus 1 the velocity state variables should be close
