Crystallographic Planes {Texas A&M: Intro to Materials}

[@brennerhall9931]

8:43 omg this helped so much. Idk why it was taking me so long to visualize it like that, but seeing it this way actually helped so much

[@Watnow20]

Thank you so much. Very Very helpful for my exam in the morning. Will continue to watch your videos for help! You teach in a way that is very easy to understand.

[@mymildxpannat715]

U teach very well. It's easier to understand. Thank you.

[@m-1782]

Thank you sir for your explanation! The way you explained it is timeless and easy to understand.

[@odins_claw]

Somehow you made this appear simple, and I suppose it is after watching your tutorial. Cheers

[@monoshiki97]

Thank you sir, after i watch this i really know whats happening and understand

[@MsAlarman]

Fabulous! The best explanation ever!

[@abushaidsujon1285]

Thank you so much Prof. I didn't understand it in the whole course which you clarified in less than 10 minutes

[@cyberhifi2629]

I am from India and your lecture rally helps me sir thankyou

[@dr.-inghuh797]

at 02:48, how does it intersect at 2 for a? why not 1. The extension from b towards the intercept on a should not be from the half but directly through the edge of the cube or? what am I missing here

[@kgaugelothobejane860]

I am also curious? is it because the length is longer than the 1 intercept?

[@erikm392]

Imagine if you had the interception of the plane with a at 1. That would also mean that the top left corner of the drawn plane (which is also at a =1) had the same position on the axis. Therefore the plane would be parallel to the c-axis if you keep the interception with b fixed (like in the following example 04:31). Also if you come from c = 2 you go one segment down and one towards a. Doing it again will lead to c = 0 and a = 2. I have to admit going from b -> a is quite difficult to spot because there is no direct line to see..

Good god this saved my life

[@juantorres27]

Excelente. La interpretación de esta nomenclatura resulta muy clara con los ejemplos ofrecidos.

[@BeeNotDismayed]

Howdy! 🤠
And thank you, brother! 🙏

[@deshdeepaksingh1182]

Is it matter where you shift the origin?? Or you could move it anywhere??

[@pjshamberger]

The underlying assumption is that all planes that are parallel will have the same indices. Thus, it is irrelevant where you shift the origin. **note: if you shift the origin "in front of" vs. "behind" the plane, you'll obtain planes with indices that have opposite signs from each other (e.g., (-1 0 2) vs. (1 0 -2)). However, as planes don't have a "sign", these are identical/equivalent.

[@Erer214]

thank you so much for the video. This video helps me a lot on getting through my HW.

[@ikeremanuel9005]

you probably dont care but does anyone know of a trick to log back into an Instagram account..?
I was dumb forgot the account password. I appreciate any tips you can give me

[@frederickjamal1808]

@Iker Emanuel instablaster :)

[@ikeremanuel9005]

@Frederick Jamal Thanks for your reply. I got to the site on google and im waiting for the hacking stuff atm.
I see it takes quite some time so I will get back to you later when my account password hopefully is recovered.

[@ikeremanuel9005]

@Frederick Jamal It did the trick and I finally got access to my account again. I am so happy:D
Thank you so much, you saved my ass :D

[@frederickjamal1808]

@Iker Emanuel happy to help =)

[@hemaupadhyay4160]

thankkuuu sir I was bugged by this question BT u made it easy

[@pasindujay]

Thank you very much sir

[@learnmore1325]

Thank you

[@garywasherefirst]

amazing explanation

[@qaeddydohny2909]

thank you for your knowledge

[@SibafeFalone]

Thanks sir very clear

[@sanaullahkamboh632]

Dear @UCpsvdl0nKBqEpMqVyXkSSeg, you teach us brilliantly. your concept forces me to write the comment I just wanna say Thank you so much. best wishes to you

[@허윤미-w1f]

wonderful !

[@laksminarayan9703]

sir what purpose we shall use Miller indices in crystallography

[@garyschasteen9440]

Thank you so much! Awesome!

[@emirhan4899]

thanks

[@serhatbugraaygor3105]

Thank you so much sir,It was pretty helpful.

[@matheussiqueira2313]

This is fantastic!!

[@art_math_enjoy]

Hi, what is the application of indices?

[@thegoodsamaritan4333]

thank you good sir.

[@brianzar1943]

Beautiful

[@laksminarayan9703]

Sir one doubt in 3rd index how c would -1 please explain

[@fisherofman]

was very helpful

[@civilizedschool2254]

That was nice sir

[@fatemaexo-l1256]

thank youuuuuuuuuu

[@komalhayat417]

awsome

[@Malookii96]

so helpful. thank you

[@eneshachamud5437]

thank you..... that was helpful

[@zaizkh4078]

thank you so muchh

[@zongyuanzhu1499]

really clearly presented：D

[@NurIlmadienaEidirania]

Tq so much for the subtitle!!!!

[@franck-paulinpehnmayo7148]

doctor, can we put 2 out for the last one then we will get 2 (1 - 1/2 1)

[@civilizedschool2254]

U have to inverse that... nothing else. that's the role

[@hammadqureshi7351]

more like thats a rule *

[@pjshamberger]

If you are asking if a plane (2 -1 2) is the same as a plane (1 -1/2 1), then this is true (finding intercepts for these two cases would result in two parallel planes). However, by convention, we generally avoid writing fractions in planar indices.

[@Maze7]

you are a god among men thanks to you i dont have to go to class thanks and gig em

[@amrradwan9144]

Thanks a lot. ^_^

[@fl6365]

Plane (1,-1,-1) ?

[@ankitamohanty8261]

I guess the first question answer is not (1 2 1). It is something else. Am i right?

[@preethamreddy6726]

Hi Professor. Thank you for the amazing lectures. I have a question about the problem from 8:17. If I don't shift the origin, the B point plane will be falling outside the unit cube. Is it ok??

[@tamannaD2909]

Thankyou so very much ! ^_^

[@Venuhmz]

funny that im taking the exact class at tamu and my prof doesnt do anywhere near a good job as this guy.

[@hyunseoksong625]

good luck on the test tmrw. i will see u in class

[@WATCHOUTyoutube]

howdy

[@RyonBang]

in his exam, Date: me please. lol
