You have a wonderful way of explaining and teaching. I was not grasping this at all in my university lectures but this makes sense to me now because of your clear explaining. Thank you
A little bit late to this video, but I want to say a huge thank you. Very well explained compared to my copy of Kittel and definitely helpful for my current research which has a bit of a learning curve for an undergrad like me. Thank you again!
the basis vectors a's and b's taken by Prof. to define any random vector in the real and reciprocal space systems are unit vectors or should be primitive vectors.
I am a little unsure about the reciprocal lattice vectors. If we say they have units of L^-1 then how can they be regarded as a vector? I see their direction but the magnitude is not directly comparable to a real space vector. Can we just say that the magnitude unit does not matter (L^-1is just another scalar quantity)? Force vectors have direction, and units of Newtons. So is this analagous? The Reciprocal Lattice vector does not have a magnitude of length but of length to the -1?
Its used for x ray diff patterns. For example you throw a beam of xray on the real space lattice, the diffraction pattern will manifest itself in the pattern of reciprocal lattice
@46:30 Although the relationships are right, your explanation of the concept suddenly runs into memorial writing of relationships rather than the usual elaboration logic you implement in your lectures, hence it difficult to understand this bit

Why does he write on the blackboard? To teach them writing? Horrible accent, slang like " you know", " OK" is NOT Ok. Poor lecturer who gets his money and lives happily ever after, ok? Haha, pretends that he works by writing instead of using PPT presentation, simply uses the time for English writing.
Also as a native english speaker, what are you talking about "you know" and "ok" as slang?? These are both used in professional settings and are not in any way shape or form unprofessional. And his accent is not difficult to understand in the slightest. What is wrong with you?

Your videos are SO HELPFUL! Thank you!!!
Best lecture I have ever watched on Crystallography.
Thanks a lot for this series of videos!
Wow sir Aaj samajh aaya jab main paas kar gaya😂😂😂
Lots of respect for your method of teaching sir
what a beautiful explanation it is!!!. I too taught this topic to my students many times. But i never followed this approach. super sir.
absolutely best class ever .....thankyou sir
Amazing channel! Thank you so much! ❤

Thank You Sir for your simple and clear lecture on reciprocal lattice
This is explained so lucidly! Thank you so much Sir, for helping me visualize Reciprocal space. :D
Thanks sir, for this video on nice reciprocal lattice concept s
Thank u very much! Youve helped me a lot. :)
Very interesting and helpful video
the basis vectors a's and b's taken by Prof. to define any random vector in the real and reciprocal space systems are unit vectors or should be primitive vectors.
no craming,got to know the use also, thankyou sir,
useful video.. :-)
I have almost understood the details of the reciprocal lattice.
Why we work in reciprocal space?
I am a little unsure about the reciprocal lattice vectors. If we say they have units of L^-1 then how can they be regarded as a vector? I see their direction but the magnitude is not directly comparable to a real space vector. Can we just say that the magnitude unit does not matter (L^-1is just another scalar quantity)? Force vectors have direction, and units of Newtons. So is this analagous? The Reciprocal Lattice vector does not have a magnitude of length but of length to the -1?
Whag does it matters. It just a constant number.....You have a number say 2 and 1/2 hardly makes any difference... Just check the unit direction
If the magnitude of b1 is not 1 can we still call it unit vector or the basis vector is a better word.
what is the purpose to take reciprocal lattice space
Its used for x ray diff patterns. For example you throw a beam of xray on the real space lattice, the diffraction pattern will manifest itself in the pattern of reciprocal lattice

thank you for the excellent lecture it was great. I wanted to ask at which books have you build it?

@35:00 How did you justify performing a DOT product on two vectors with different sizes? Can you please explain it.
Did you get it now? I have same confusion
thank you sir
Thalai keezh veli.
How many lectures are there in the whole course?

So you want profs to be national tv anchors or journalists????
3 years ago so I hope you've grown as a person because this comment is deranged...
