Chirality —Didier Enjary
LEGO and chirality Chirality is the property of an object that can not be superimposed on its mirror image. Examples includes both natural (biological) object such hands and cultural (technical) object such screws. A non-chiral (achiral) object can (...)

	Re: Chirality —Larry Pieniazek
	(...) Good stuff. Seems BrickWiki fodder! I would footnote that many paired parts are not TRULY enantiomers since the logos on the studs are not reversed. But that is a very unimportant footnote since they are functionally mirrored. (19 years ago, 8-Sep-05, to lugnet.build.schleim, lugnet.parts)

	(...) snip (...) Your post reminds me of my painful memories of organic chemistry from university... Never thought it could be applicable to things other than molecules! :) -Bryan (19 years ago, 8-Sep-05, to lugnet.build.schleim, lugnet.parts)

		Re: Chirality —Mark Bellis
		(...) I find that animals and plants make some of the most interesting MOCs. There are families of plants whose leaves are chiral. There's one particular house plant that I can think of, but I can't remember its name. I think some types have leaves (...) (19 years ago, 8-Sep-05, to lugnet.build.schleim, lugnet.parts)

		Re: Chirality —Bruce Hietbrink
		(...) Funny. Actually, you apply chirality every day when you put your shoes on--you put the right shoe on the right foot and the left shoe on the left foot rather than vice versa. You just aren't thinking about the terminology when you do so. :) (...) (19 years ago, 9-Sep-05, to lugnet.off-topic.geek)

	Re: Chirality —Anita Eenink
	(...) I will never look at my bricks the same.... what a great idea for a lesson plan, I have written it down to tell my sister (a secondary science teacher), I am a training early childhood so chirality isn't on the curriculum :(. Is there nothing (...) (19 years ago, 8-Sep-05, to lugnet.build.schleim, lugnet.parts)

	Re: Chirality —Bruce Hietbrink
	Hey, Awesome post! Larry has a point with the text on the studs, but when I teach symmetry and chirality and talk about everyday objects I always put in the caveat "this baseball has such-and-such symmetry properties, igoring all imperfections and (...)

			Hey, Ley Does that pattern repeat beyond the cube that you show, or does it stop there? Just curious... James Wilson (19 years ago, 26-Sep-05, to lugnet.build.schleim, FTX)
