Calculating the Miller Indices for an HCP unit cell

[@219something219]

I CANNOT EXPRESS HOW THANKFUL I AM TO YOU SIR! I HAVE A MIDTERM TOMORROW AND I DIDN'T KNOW THIS AND YOU SAVED MY LIFE! GOD BLESS YOU SIR!

[@Svperiore]

Good morning sirs

[@cryotankexpansion]

FINALLY I understood the Miller indices, thanks to your video! Wish you the best, and keep up the good work! Greetings from Brazil ;)

I understood the Miller indices, thanks to your video :)

[@sickleandsuckle]

Man crystallography teachers don't give HCP enough love :(

[@kamrankhankami7793]

love your explanations sir

[@abdelrahmangamalmahdy]

why converting the coordinate system ?!! and from where did you come up with these equations of transformation ?

[@adamflynn7131]

I love you I love you I love you this is the 7th video ive watched and the only one that makes sense, you are awesome, did i mention i love you? You just made me so happy that I almost forgot harambe has been dead for over a year

[@jbonn5]

Huge help, thanks homey.

[@jwkim5050]

great video. I guess my question is, in order for us to draw directions on HCP, would we always have to convert from miller-bravais indices to normal three indices to draw them on HCP? Or is there a way to draw straight from the miller-bravais indices? Well thank you any how.

[@mohamedoraby8044]

please answer me, why hexagonal system has 3 horizontal axes (a1, a2, a3 ) than other systems?

[@jonthegeologist616]

Really good video

[@Spodlude]

What software do you use to make these tutorials ?, I guess it works with a digital writing pad of some sort aswell ?

[@jeanpierreattard1319]

I thought A did not equal C!!! How did C/2 become 1/2 ? please an answer asap!

[@hermansong9745]

yeah, but in the z-axis C length is unit length:)

[@momo0000]

If we are using a1 and a2 at the start. Why can't we just ignore a3 when we change it to 4 digit miller indice. Eg. [1 2 0] = [1 2 0 0] ?

[@earthquake861]

Thanks so much, such a useful video ...

[@rajatjays9785]

nice explanation...

[@ibrahimtunahandag6081]

4.19 am I blind or sth or did he just say that a is not = to c then divide everything and write -1,1,1/2 pretending like a = c?

[@mustafaabduallah2096]

Pretty good

[@BBLitchi]

Thx really helpful.

[@MohammedRagab16498080]

very nice keep it on

[@Bariyereba]

Thanks very much sir

[@mbakssa]

Thanks, your video is good..

[@herrschultz7413]

THANK YOU

[@distilledleemupaani9232]

i have some questions and i'll be grateful to anyone who can answer these 1. why was there a need to establish a fourth axis ? why cannot the same thing be done with only three axis? 2. why did you traverse to the head of the vector from the axis a1 and a2 ? why didnt you choose to describe the vector in terms of a3 and a2 or a3 and a1, just take a2 equal to zero and a3 equal to 1.

[@Dianabanda902]

Genius

[@moh123456789egypt]

Y not just use a2-a3-z, so a2=0, a3=1 & z=1/2 ?
