Directions in Hexagonal Systems, Talking Head

This is the "Talking Head" version of this topic, including three examples.
I have posted three versions of this topic (1.Annotated Tablet, 2.Talking Head, 3. Chalkboard) and I'm interested to learn which version people find most useful.

omg man you saved my life with the idea of that cube i wast able to imagine the projection in the hexagonal shape at all

[@AcrobatMr]

This is very useful. I am so used to cubic systems and i thought the ease would transfer across. This systematic approach fixed my head a little. Thank you.

[@emvee5719]

Seriously appreciate these videos! My teacher asks very uncommon questions for these though!

That's really a great explanation.!! tnx a lot

Thanks a lot. Perfect.

Such a hard topic. Thank you for such a good explanation

[@i.debraliz]

Great explanation! My professor skips over all this stuff. It makes a lot more sense now.

How does it travel in the x? It moves along the y axis, not x at all.

Thank you sir , you are my life saver

the best explanaiton that i've seen

[@alienmoondudes8071]

This video was very helpful! Thank you for your post :) I think I like the annotated tablet better, or the video with a white background. It is easier to understand. I do like how you show your face in the video too, but the transition is kind of abrupt. Maybe a fade or if you greenscreen your body in a corner I think it would be better. We can still see you talk, but at the same time not get distracted by the face changes

[@theadel8591]

in 2:41 you constructed a cubic unit cell to represent a vector that's originally in a parallelepiped, why? aren't the dimensions different for each of the two structures ?

turning a hexagon into a square is by far the dumbest thing I have encountered in my time studying chemistry

[@ica885]

Am I stupid or I just don't understand the "easy math" part?

[@ica885]

Anyways, thanks for this clip...

[@pankajghansela853]

I think it's because what he means by "easy math" is that these expressions are pre-defined, so you just need to substitute the "temporary " 3 index values to convert it into 4- index values ...

[@prithvikrishna5830]

namaste sir, while drawing a cube in hexagon, u mistook 120 degree to 90 degree, i guess.

[@soumyadeepkarmakar9333]

Here, the a1 and a2 axes, though separated by 120 degree, have been assumed to be perpendicular so that a1, a2 and z axes can be considered orthogonal. It's just an assumption, and not exactly accurate. That's why the three axis indices system here is temporary. So, the action is deliberate. Hope it helps.

How is w=1

[@eliasescotolara5386]

the Z direction doesn't change so w=w
