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?
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)
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.
@@flydia I have no recollection of typing the original comment, but looking back at it now I have no idea what I was talking about, sorry about that chief! Thanks for taking the time to reply (which I didn't notice till now, either).
Lydia my name is Cosme Souza, a brazilian chemistry student, and I'm really grateful to have come across your vídeos. Thanks to your clarifying explanations, especially about chirality. You literaĺy saved my life. God bless you. I'll stick to your vídeos from now on.
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!
Seriously, I never comment on videos but this is just so amazing and simple explanation which many of the teachers fail to give...good job keep it up 👍
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)
I felt lost you when you brought purple as the last colour because I'm colour blind and can't distinguish it from blue. You were rotating it to show that they aren't identical but they look exactly the SAME to me. Good demonstration though!
I'm a NEET ( Indian medical entrance exam ) Aspirant And was struggling to understand mirror image rotation , spent hours searching in books for explanation But unable to find any , left it Now after nearly 8 months since I read it , my doubt is clear : )

That is just it in a simple language! Many textbooks make it fuzzy and confusing. Glad you made it quick and simple!
Duh that's what Babel is.

You are responsable for an "Aha!" moment, thank you!
You are a gifted teacher, please help us future doctors by making more videos on biochemistry! Ever grateful.
Thank you so much! This is by far the easiest to understand explanation I have found.
Ann Blodgett ya true
that was such a neatly explained video. Thanks for taking the time to post:)
Saved me a ton of time I could better spend on other MCAT subjects.
It always takes a woman's touch to get the point across.. thank you : )

THANK YOU for this video I was going crazy trying to understand this
Heyy, How's it going ?😂😂
You did so good at explaining it I got it right away.
My god, I think I've finally got it! Thank you so much for using actual 3D objects to explain this.
Thanks a lot. My chem teacher sucks at explaning and he yells at us. You are a life saver!
Cheers from Portugal
For the first time, it made sense to me. Thanks
Thanks a lot..I watched so many videos about this but I was not understanding the actual concept..you made it very clear..what an explanation
This video is the best so far. Others are just confusing.
THANK YOU SO MUCH! The concept of chirality was eating up my head but you cleared my confusion completely!
You have a very beautiful voice and your explanation really helped me, thank you!
Thank u so much I'm been searching for a long time to know what exactly chirality is . And thanks for using tetrahedral shape to explain it
Very good . Wise men had said true that "simplicity is not a single thing." But simple is understandable. Keep it up 👍👌💪👍👍💪💪💪💪💪💪💪😘😘😘😘😘😘😘😘😘😘
Thissss is soooo gooooddd thank you soo much ….now i m very clear about chirality
Best of all the lectures about chirality because it clears achiral as well
This is video really did clarify my confusion with chirality. The use of examples are very helpful. Thank you very much.
Thanx mam.... It was very helpful.... Ka m from India 🇮🇳 ....... You are doing very well 👍keep it up...
Now only I got a clear idea about this concept.thank u Soo much man
i have no words to say
i love your explanation. i was looking for it
you got a new sub
cheers
#love
Incredibly helpful thanks a lot!

How you doing mate ? It has been 7 years since you were here
I love your explanation please continue making videos! It makes more sense now and thank you !
thank you a lot for this detailed explanation with many examples. it was exactly right for my weak space imagination.
this is just PERFECT! thank you soo much, our teacher tried so hard to explain this but wasn't successful :D
Amazing! Thank you so much! My prof is a jerk who doesn't answer any questions and this SAVED me!
:)
Superb Explanation Ma'am ! 🤩
TH-cam recommend after 8 year... Seem like u have made this video in 2021 🎉🎉🎉
Wow Lydia, a beautiful visual explanation. Much clearer than the TedEd vid on chirality. Thank you!
Thanks, I understood it.Your way of teaching is awesome.
omg, thanks a lot for making this video... it is truly, extremely beautiful and i am seriously so grateful and amazed
This great video was shown to us in the lecture and I came here to rewatch it and thank you!
Thanks Lydia, very clear and helpful explanation :)
Thank you for this! Really helped me visualize and understand the concept.
Holy banana... this was so simple yet so helpful!
So Did you understand it? 😂
Nice presentation.
It was exactly what i was searching for
Thank you👍🏻
thanks for the great effort
Very nicely explained
Fabulous 🤗🤗🤗make more👍👍

I wish youtube existed when I was in high school, holy shit thank you.
Thank you ! Very clear !
Thankyou it gave me clarity
Well done!
awesome video. all my doubts were cleared.thank-you.
thanks for your wonderful explanation
now my concepts are crystal clear
david was here
Omgeee Thank you for this explanation!!!! =D
very nice explanation
Thanks a lot! Direct and to the point.
*Brilliant Understood It immediately*
I felt lost you when you brought purple as the last colour because I'm colour blind and can't distinguish it from blue.
You were rotating it to show that they aren't identical but they look exactly the SAME to me.
Good demonstration though!
I subscribed your channel with this video
You are the best!!!!!
That's fine... 👍
this is a great explanation. Went through your channel.... Y U NO MAKE MORE VIDEOS !! ?
I'm a NEET ( Indian medical entrance exam ) Aspirant
And was struggling to understand mirror image rotation , spent hours searching in books for explanation
But unable to find any , left it
Now after nearly 8 months since I read it , my doubt is clear : )
Good job, u made it easy to understand it.
If an object has at least one axis of symmetry, it is achiral. Is this deduction right?
Posso publicar seu vídeo com alterações, sem fins lucrativos, traduzindo para o Português?
you rock ! thanks ! the best explanation over youtube !! keep on !
great...
❤❤ma'am you're very beautiful 😍 😍😘 but also your experience in exploring the concept
Good video NOSS IDENTICAL
many many many many thanks
Thank you.. you saved my life
well done mam😀
Great
Thank you so much mam,it made me understand quickly
Why is the second molecule chiral? At 2:34 they look like the same object.
Thank you so so much
Will u help me to understand some concepts
Simple and effective explanation (y)
Can 2d molecules be chiral? Please tell me... I can't really understand how us it possible for 2d molecules to be chiral
Thank you very much! Very useful video!
Thank you so much,it was very helpful 🙏🙏🙏
Great video! You have a soothing voice!
Is this dp picture is your?
I watch One breaking bad clip and now this is recommended to me
Thanks so much
thank you for this!
no words to thanks
Now I understand👍
thanks alot ma'am :)
