C to a ratio for hexagonal close packed (c/a=1.63)
In this video, Parisa works through the calculation of the c:a ratio for the hexagonal close packed HCP) crystal structure. The final answer is c/a = (2sqrt2)/sqrt3 = 1.63.

You put something hard - in an understandable way. Great teaching style :)))
This is actually really easy to understand! she explained it so well. Thank you so much!
I am extremely impressed by such a simple way of Your teaching ..... Thank you very much......
Why didn't you film the video till the end? This is a very good explanation. She is solving it in the easiest possible way. Thanks for uploading!
Thank you Parisa, this helped greatly!
Thanks! I could not understand at all how to approach this problem and this helped a lot.
how can we find the size of biggest tetrahedral and octahedral site in hcp unit cell?
Thank you for this video! I know that just the ending is wrong, but never mind that.
how do you find the radius from the ratio?
In diagram 2, shouldn't the line of length h pass through the centroid of the base triangle?
Thank You! I was so tired and staring blank at my homework. Really helpful :)
Practically: Is C then the minimum packing distance between Graphene sheets?
In my country we are used to say things like: Vine buscando cobre, pero encontré oro. It means that I was looking for something but instead I found some other thing that overpass my expectations. Congrats lady

Hello , Please note that there is a calculation error , the end result should be 2√2/√3
keep these material science explanations going :thumbsup:
Thank you so much for your Help!
thanks lady... i'm from peru and your lesson was very good
helped me a lot, ty
Thank you very much you really simplified it alot
Thank you for the explanation. Very helpful

Excuse me there is error ! who you find this equation c^2/4=2a^2/3 with out negative signal for a^2/3?
If we had a teacher like you mam❤️
Really great explanation so easy to understand great lecture at a young age great journey ahead on ur career ma'am
can you make a video on Calcium Fluorite structure, explaining its IPF
Pretty disgusting to see all these people commenting on her looks. It's really not relevant to the video and I'm sure she just finds you all pretty creepy.

Agree completely! I could not believe what I saw when I scrolled down to the comments in order to see what relevant questions people might be asking - how are there more comments about her looks than about the subject of the video? It's like these horny boys have never encountered a human female before....

she needs to focus more on her computational skills and less on drawing pretty pictures.. then again, it is materials engineering...

considering she's the one doing this video and not you, i would wager that she's far more intelligent in this subject than you may hope to be at your age.

also if you understood how important it is to have an accurate and clear depiction of the surface you're working on in order to be a decent purveyor of complex information such as solid state physics, you might see why it's important to focus on "drawing pretty pictures".
Muchas gracias
Thanks a lot
thanks
thank you 😊. .
One like for ur kind of explanation 👍
I thought the central atom of the .....2D hexagon fits into the void of the 3 atoms cental atoms of 3D hexagon .but her Ur taking as if they are (atoms)touching .
Very cute concept
Thanks
super!
face of paradise ^.^
pretty good explanation ... but at the end you forget to put 3 under square root...
I would turn up to every lecture if she was teaching me
....??? Country?
Thanku❤
One question. How did you know that hypotenuse is a/2?

A total of six tetrahedrons in that one hcp lattice
Thank you maam my problem sol
At the finishing ... I think c is equal to 2root(2)a divided by root(3)
Did it hurt? When you fell from heaven.
maths in last step is wrong c=2(squr2)a/(squr3)
very good
I loved
Did you not miss a root 3 in the denominator

Ok, how is she using the properties of triangles to find X? X is in 3 dimensions, when she solved for X, she actually just solved the projection of X on the surface created by a,a, and a
Nice thanks
Great❤❤
