Chirality tutorial explaining the basic concept - some objects are identical to their mirror image and some are not.

Sorry if I am miles off here, because I like your style of explanation, but ... aren't you being very casual with the word reflection? I mean ... no object IS its reflection, but it's always identical to it (in a way) or its not actually its reflection . no?

@splodge9 7 жыл бұрын

Like ... you thow a mirror in ... and you use the word reflection, but ... the mirror does the square root of fuck all in your example, so why even mention the word reflection? Am I wrong? (Probably)

@flydia 7 жыл бұрын

You're completely right on the first point about "is" and while I agree generally about the word "reflection", I am inclined to think it is overly pedantic, because actual reflection -- e.g., light bouncing off a mirror -- is (I hope) *obviously not* what we are talking about. That doesn't answer your question about why actually use this metaphor as a pedagogical aid... I do not think most people have *really* noticed chirality as a phenomenon -- daily living does not inspire us to really articulate that some objects can be super-imposed on their mirror image and some can't. In my experience, that is the main barrier to understanding this topic (people just haven't articulated/gripped that fact enough), so the raison d'etre of the video was just to bring that concept to life. I think the use of the mirror and the pretend "reflection" does, at least for some people, succeed in doing that.

I would use "complimentary"; and "reflective" & "non-reflective". Which would also replace the negative word - describing a positive reality, and vice-versa (chiral - doesn't reflect; achiral - reflects). But education is historic - so they won't change it.

Thanks for the video. I realized the way I was visualizing and rotating these objects didn't consider certain rotations such as the one at 1:24. Thanks so much! It felt like some of the answers and explanations I've gotten elsewhere were contradictory/incorrect. But, now it makes sense! My suffering is no more and I learned something new today!

Two compounds with same atom composition (that you showed with coloured balls) are not always each others reflection. The position where each atom is fitted matters. If the blue is on right it should be on left in the mirror image. So saying that "after rotating if its identical to original, its mirror image" is wrong. You could put a compound in a wrong orientation (hence not a reflection) but is exactly the same after being rotated 'a few times'. Conclusion : just one complete rotation (exact opposite of reflection = original)makes a mirror image. Tho you did put your compounds' reflections very mindfully to begin with (the right way)

The feet were achiral.. they could be superimposed.. it was just the back was different.. but the shape tho

@richardhead8264 6 жыл бұрын

Emperor Imagine if the two feet were able to pass through one another and occupy the same volume of space. The hollow openings would face in opposite directions. This factor makes them chiral. Conversely and hypothetically, if the feet where not hollow, and looked the same on both sides, then such feet would be achiral.
