In studying for my first mineralogy test, I've watched through all of your videos in this Crystallography series in the last couple of hours. I've just got one thing to say: you're a fantastic teacher. Thanks so much for all of these lectures. The "voiceover+blackboard" approach (Khan Academy style, as I call it) is so much more efficient than just watching someone lecture and have to draw slowly and sloppily with chalk for hour long lectures. Great crash course, hope my classes have more overlap with your videos so I can watch more in the future.
why did he have to change the axis when the first value for x would have been infinity ? I thought you would only need to shift the axis if a point of the plain intercepted at x,y or z = 0 ?
I hope THAT Nice nanoscience guy didn't died.. someone ask on quora ..! , He used THAT , may be that guy was already died before making videos, if THAT makes sense. 0_o ?
***** look, if you look at any unit cell in reality. there is no difference between the planes that are from the same family. and also you can pick any point to be the origin. nothing is special about the point (0,0,0) you can easily convert the axes. so if you convert the origin it will not make any difference at all , so you can refer to the same plane and know its miller index using these transformations.
***** if you move the origin to point he specified, it still doesnt intercept at x=-1, it should be intercept at x=infinity, no? Because it would not intercept the x axis.
How many planes are in {100} family? just the 6 surfaces or do you count every plane with the same orientations but inside the cube so that you get infinite number of planes inside the family?
It's just the 6 surfaces. If you look at any cubic unit Cell (Simple Unit, BCC, or FCC), then all sides of the SURFACE will look exactly the same. (ex: fcc has 1/8th of the lattice point at the corners, and half at the center), though it wouldn't be the same if you look at a parallel plane on the inside of the cube. Which is why he specified it's only in the same family if you could rotate the cube and overlay it.
I'm pleading to please, keep uploading more videos on this. I really need them, all those who make videos on crystallography are Indianans and have a freaking accent that's really hard to be understood -_-
Nice video, but O and 0(zero) are two different things, and should be treated as such. I don't understand why Americans invent these crazy denominations🤣🤣🤷🏻♂️

We would love more vidoes, you seem to be the only one capable of understanding and explaining it on youtube!
Please come back! Your videos are so much better than my lecturers!
Please come back Nano Man...
We are desperately waiting for the rest of the series ...
You explain it so well! Thank you so much!!
why did you stop making videos ? :(
Thank you for making this video! It helped my to understand Miller indices when previously I was so struggling on this
how did he get -1 on the x axis in the second plane?
I have an absolute disaster of an MSE professor. Thank you for being his replacement.
We need more videos! Good job!
Nano man, please come back.
at 5:27 and on, WHY is a new coordinate being used? None of the plane is going through the origin. It is unclear why even then x becomes -1. Anyone?
You can calculate the plane function using three points that we already know, and then let y=z=0 to calculate the x-intersection.
Excellent teaching style, I really like.
all 24 possible slip systems of {110} is wanted from me, i need to know the combinations, what are they and how can i find them?
Will you be covering the concept of reciprocal lattices and reciprocal space in future?
please make more vedios , you became my guru for crystallography
Please come back. We need you.
why did he have to change the axis when the first value for x would have been infinity ? I thought you would only need to shift the axis if a point of the plain intercepted at x,y or z = 0 ?
5 years later and I have the same question
THE PEOPLE WANT MORE!!!!!!!!!
how do you decide on what axis to rotate??
Brilliant lectures.
I have an question. Can i write {001} instead of {100}? Does that mean the same family of planes
and then the Nanoscience Guy died
really ?
I hope THAT Nice nanoscience guy didn't died..
someone ask on quora ..! , He used THAT , may be that guy was already died before making videos, if THAT makes sense. 0_o ?
This is sad
I was hoping to see you there too
Thank you so much .
I don't understand how the corner will intercept x axis at -1. Any help please?
Right now it is intercepting x at 0. Now do change of origin and what used to be 0 is now -1. That's it! (He did similar thing in a previous video).
***** i dont understand what he did there either
***** look, if you look at any unit cell in reality. there is no difference between the planes that are from the same family. and also you can pick any point to be the origin. nothing is special about the point (0,0,0) you can easily convert the axes. so if you convert the origin it will not make any difference at all , so you can refer to the same plane and know its miller index using these transformations.

+Abdulrahman Mahdaly I am pretty sure he is wrong. The plane should be 1 1 (bar) 1 (bar).

Soo true
Where'd you go nano man
Thanks, nice introduction.
Can anyone plz said that how many members in the family of plane of {100} ?
Is it 4 {(100),(001),(-100),(00-1)} or anything else, plz correct me
Please sir can I have some more!
Are there more videos?
I hope to see you there..
keep going
Need more videos.
Plese, come back 🙏
where are the others videos ??
I hope not to netsawّa7 ya man
:D
thanks alot
the rest of the course pleaseeeeeeeeee.
where the other videos
more!
I really hope he is not dead or something..
Nice video, but O and 0(zero) are two different things, and should be treated as such. I don't understand why Americans invent these crazy denominations🤣🤣🤷🏻♂️
