No, atoms are more simple than ducks, and atoms are also more frequent than ducks because there are atoms in every duck but there is no duck in an atom. However, it seems that every object can be represented as a binary string, which is a useful representation in computer science. > What a load of garbage!

"Grue" means "green before time t (for example year 2030) and blue after time t". More complex properties are less frequent than simpler properties. For this reason, and given the way the world has been until now, objects that have been observed as remaining green in the past are more likely to remain green in the future, instead of becoming blue at some time. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
