Working with Crystallographic Planes and Miller Indices

[@ochoytnik]

I wish that I had youtube when I went to university. I got stuck here and there was no help so I couldn't continue. I am glad others can understand this, thank you.

[@cellefson96]

This video helped me understand this concept so much!!! Thank you from Louisiana!!

[@ifyjossy98]

You treated it so well that anyone can understand it (my opinion). Keep up the good work.

[@chriskenedy1305]

Thank you so much! I've been trying to get around the odd notations in crystallography, and this was a big part of the list.

[@hiltonkelsey9]

6 years after publishing and this video helped me!

[@heezyyyy]

our professor doesn't teach us like this. She'll just give us the topics then we're on our own.

[@kevingorgealex5095]

Thanku..this lecture gives a clear and comprehensive picture about the Miller indices of planes.

[@sanjibthakuria9760]

completely understood sir why dont we have such professors in our college

[@ludwigboltzmann6524]

because u of t gets the best of the best

[@harinisuresh456]

I jus though the same bro

[@yanlord3979]

because they're too busy defecating on the streets

[@KAMU13]

Because higher education universities and institutes (incl. IITs) in India rank beyond 500 in world university rankings. Keep hiring those SC/ STs and sons and daughters of ministers.. what do you expect?

Thank you so very kindly professor, please take care! Thank you!!!

[@anthonyjnr.alakpa2135]

This is a fantastic lecture. I understood from the very first example. Thank you. 🎉

[@jor4776]

Perfect explanation, you are exceptionally clear.

[@EkaraLibrae]

Well that was easy, simple to follow - to the point discussion on planes.

[@EwanOkyere]

Thank you very much I understand this way better now

[@ScottRamsay]

That’s great to hear! Glad it was helpful.

[@ahmedhegazy699]

Beautifully explained! Thank you

[@tharangadilrukshi343]

Perfect explanation. Thank you

[@AtticusEluih]

Thanks.... quick, easy, concise explanation.

Thank U from Iraq 🇮🇶💞

[@zachary811]

Since I can choose any origin for any plane won't it give a different set of miller indices?

[@worthurattention]

completely understood sir... Thank you

[@tomriddle197]

can you please make a vid for a negative plane, as in by shifting the origin to such a point that you have intercepts with varying signs

[@ashutoshsavita2995]

Awesomely taught sir. thanks a lot

[@Frank_The_Tank22]

Outstanding, thank you for sharing!

[@frahmawati9495]

thank you so much, such a very clear explanation

[@josecarlosdelgadomalave2353]

If I'm given the intercepts (2, -3, 1) the miller indices would be (3,-2,6), so far so good, but if I'm asked to draw the plane given those miller indices (reciprocants would be: 1/3, -1/2, 1/6) the sketched plane would look different from the one sketched using the original intercepts (2, -3, 1), shouldn't the have the same shape? What do I do in these cases? great video btw

[@monicasenese2839]

Great instruction- thank you!

[@Zenda123ss]

thank u verymuch. u are the man, once again thanksss

[@josegamez4714]

Thank you so much.

[@rohandesai7833]

thank you so much! Really helped

[@BioPhys92]

Thank you, that was helpful. I know you touched on it at the end, but just to confirm. So the parallel planes (the other three sides of the cube), they aren't required because they are just 'translations' of the planes you did shade in?

[@Redfield2142]

Clearly explained. Thankyou.

why family of palne became {001} ?

[@YamiMao]

Why didn't I search for the topic online earlier? I tried understanding this myself for the whole day, and it didn't work... And watching this 8 min video at 1.5x was enough for understanding it all

nice lecture sir

[@vijy9980]

Can I rotate the coordinate system by 90 degrees in any direction? If my intercepts are correct, I should be fine, right?

[@ScottRamsay]

If you mean just axes and not the plane also, then no. This would result in a different plane. For example, looking at the front face of a cube along the x-axis, you’d be looking at the (100) plane, but looking at a cube face along the y-axis you’d be looking at the (010) plane. If I rotated the whole thing, axes and planes, 90 degrees about the z-axis then the plane would remain the same but my perspective would have changed.

[@vijy9980]

@@ScottRamsay Yes that's what I mean, effectively you're just changing the orientation of the piece of material whose properties' directions you are representing with miller indices right?

I was expecting more examples including negative axes

[@ScottRamsay]

Thanks for the feedback. That’s a good point - I should put together some videos with more challenging examples.

Sir, intersection of planes what is this and how many possible planes can intersect

thanx it was helpful

[@jittitsk1829]

wanna easy ways for other more &Thanx for this

[@Emeishiwu]

thank you sir.

[@brittwade3127]

I don't understand why we draw these planes. My teacher told me how and never said why, but wants us to explain the significance of the plane itself.

[@HotChick_Gardener_NorthTexas]

Britt Wade that’s the direction of Crystal grow

[@GracefulMusefulQueen-xm3uf]

5:56 guys why z is not 1 and is infinity?

[@ScottRamsay]

Good question. This is because we are noting the intercept with the axis and the plane is parallel to the z-axis, so it will never intercept, or we say it intercepts at infinity.

[@awesomeharlin]

Why is it not (210) in the second plane?

[@uzmasaeed1028]

we are not multiplying it rather we are taking inverse of the indices

[@1murkeybadmayn]

it's because the z = up axis, y = bottom axis and x = the axis or line that comes out towards you. If you switched the x and y axis, you will get your answer (210). I'm gonna guess you thought the x axis is where the y axis was supposed to be? it depends how you label the axis directions before hand.

[@zero-ui1ew]

Hey in India we learn this in high school competive is this normal?

[@gijs6560]

Why does 1/2 become 2 in the second miller indices?

[@v.c.coldwater2071]

Exactly. Shouldnt it be (210) after reducing it by multiplying with 2

[@mohdhalimjaafar324]

i don’t understand why the 2nd cube is (120) anyone can explain

[@mooonyabdauil5685]

Peace be upon you, excuse me doctor, I have a question I can't solve. Can you help me solve a question, please?

[@ibrahimmerah2012]

the second plane (121)

[@nicolas.leger3]

Too easy examples

[@sahilsangwan3337]

second plane is( 210) not (120).

[@jesimusicgirl119]

+sahil sangwan How so? It looks like 1/2 in y.

[@Adil_shares]

jesi you are right

[@saritar8819]

+sahil sangwan it *is* (120) because it intercepts all the way through x, giving 1, half way through y, giving 1/2. The reciprocal for 1/2 = 2. And parallel to z, giving infinity, with the reciprocal being 0. ∴ (120)

[@1murkeybadmayn]

I think the confusion is because he did not label the axis before solving. The z = up axis, y = bottom axis and x = the axis or line that comes out towards you. If you switched the x and y axis, you will get your answer (210). It all depends on how you label the axis

[@coldstopdrop]

x,y,z,e,d there are 5 dimensions

[@hansbadal5654]

you're so cool bruh, DW we all took linear algebra, anything beyond z axis is philosophy, but i guess we can still do calculations. tell me how you're going to draw time on this diagram.
