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 👍
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 : )
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!
Great Video! One question : I am currently reading a paper about crystallography , and more specifically about the P63/mmc . From searching I found that 3 denotes the chirality. What does this actually mean ? Thank you in advance
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.

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 a gifted teacher, please help us future doctors by making more videos on biochemistry! Ever grateful.
You are responsable for an "Aha!" moment, thank you!
Thank you so much! This is by far the easiest to understand explanation I have found.
Ann Blodgett ya true
It always takes a woman's touch to get the point across.. thank you : )
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.

Thanks a lot. My chem teacher sucks at explaning and he yells at us. You are a life saver!
Cheers from Portugal
THANK YOU for this video I was going crazy trying to understand this
Heyy, How's it going ?😂😂
My god, I think I've finally got it! Thank you so much for using actual 3D objects to explain this.
This video is the best so far. Others are just confusing.
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
Best of all the lectures about chirality because it clears achiral as well
Very good . Wise men had said true that "simplicity is not a single thing." But simple is understandable. Keep it up 👍👌💪👍👍💪💪💪💪💪💪💪😘😘😘😘😘😘😘😘😘😘
You did so good at explaining it I got it right away.
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
THANK YOU SO MUCH! The concept of chirality was eating up my head but you cleared my confusion completely!
For the first time, it made sense to me. Thanks
You have a very beautiful voice and your explanation really helped me, thank you!
Thankyou Mam!, Your video is best on RUclips which explain the concept in such a wonderful way!!
This is video really did clarify my confusion with chirality. The use of examples are very helpful. Thank you very much.
I got recommended by our teacher today. I now get it why. Thanks😄
loved the fast explanation and sped up writing so much, please continue your wonderful work.
How you doing mate ? It has been 7 years since you were here
Finally The only best explication ❤️❤️
Thank you for your helping
Incredibly helpful thanks a lot!
Now only I got a clear idea about this concept.thank u Soo much man
Thissss is soooo gooooddd thank you soo much ….now i m very clear about chirality
Thanx mam.... It was very helpful.... Ka m from India 🇮🇳 ....... You are doing very well 👍keep it up...
i have no words to say
i love your explanation. i was looking for it
you got a new sub
cheers
#love
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!
:)
I love your explanation please continue making videos! It makes more sense now and thank you !
Wow Lydia, a beautiful visual explanation. Much clearer than the TedEd vid on chirality. Thank you!
omg, thanks a lot for making this video... it is truly, extremely beautiful and i am seriously so grateful and amazed
Thanks, I understood it.Your way of teaching is awesome.
Thank you for this! Really helped me visualize and understand the concept.
This great video was shown to us in the lecture and I came here to rewatch it and thank you!
Super madam I am your new subscriber from India🇮🇳🇮🇳🇮🇳🇮🇳
Thanks Lydia, very clear and helpful explanation :)
Holy banana... this was so simple yet so helpful!
So Did you understand it? 😂
It was exactly what i was searching for
Thank you👍🏻
Superb Explanation Ma'am ! 🤩
thanks for your wonderful explanation
now my concepts are crystal clear
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 : )
RUclips recommend after 8 year... Seem like u have made this video in 2021 🎉🎉🎉
awesome video. all my doubts were cleared.thank-you.

Omgeee Thank you for this explanation!!!! =D
thanks for the great effort
❤❤ma'am you're very beautiful 😍 😍😘 but also your experience in exploring the concept
Can 2d molecules be chiral? Please tell me... I can't really understand how us it possible for 2d molecules to be chiral
If an object has at least one axis of symmetry, it is achiral. Is this deduction right?
Thank you so much mam,it made me understand quickly
Thanks a lot! Direct and to the point.
Thankyou it gave me clarity
Thank you.. you saved my life
how do you draw optical isomers? i mean, to which groups are those bold lines and dotted lines supposed to be joined??
you rock ! thanks ! the best explanation over youtube !! keep on !
Simple and effective explanation (y)
*Brilliant Understood It immediately*
Good job, u made it easy to understand it.
Thank you ! Very clear !
Why is the second molecule chiral? At 2:34 they look like the same object.
Thank you so much,it was very helpful 🙏🙏🙏
That's fine... 👍
I subscribed your channel with this video
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!
Thank you very much! Very useful video!
Very nicely explained
Fabulous 🤗🤗🤗make more👍👍
I wish youtube existed when I was in high school, holy shit thank you.
Do you know how the amino acid molecules of cellular proteins are left handed only and why they need to be?
Thank you so much .This was so helpful
Nice presentation.
this is a great explanation. Went through your channel.... Y U NO MAKE MORE VIDEOS !! ?
had that im my medical school 1st year chemistry book, but without any example it was useless - HUDGE thanks for clearing that UP :D
You are the best!!!!!
Good video NOSS IDENTICAL
Well done!
very nice explanation
Hi I loved this video, it really helped me a lot!!! Keep going!!!
Great
david was here
madam can i use your video for my channel reference ?
many many many many thanks
Great Video!
One question : I am currently reading a paper about crystallography , and more specifically about the P63/mmc . From searching I found that 3 denotes the chirality. What does this actually mean ?
Thank you in advance
Great video! You have a soothing voice!
Thank you so so much
this really helpful . thank you
great...
Will u help me to understand some concepts
Is this dp picture is your?
thanks ..very good method ...im from jordan
thank you for this!
The feet were achiral.. they could be superimposed.. it was just the back was different.. but the shape tho
