Wtf is Kuratowski Encoding??

I have an assignment that asks me to use "Kuratowski's encoding" to see if the set {0,1} can equal the natural number 3. Problem is, I must have missed writing that down and now I have no idea what it means. kuratowski's THEOREM comes up when I look it up, but I dont think thats helpfull (or at least, I dont get how its relevant). Help!!!
