How are our hands chiral?? How are human hands chiral at all. Put them in the praying position and they are superimposable! "The left hand is a non-superposable mirror image of the right hand; no matter how the two hands are oriented, it is impossible for all the major features of both hands to coincide" says wikipedia. Some of my teachers and friends say you cannot rotate them like that but clearly we can orient them in any way we want so in the praying posiiton when palm faces palm hands are superimposed I dont understand this at all - why are hands referred to as chiral at all?
