I think this discussion will never get anywhere. Best Wishes
2. How to Proof c/a=1.633 in HCP?

As I said I have complete solution of this very simple problem. Your system does not let me to wirite: 1. Equation 2. Draw a triangle Mathematic problem does not need Enlish language, because mathematic...
3. How to Proof c/a=1.633 in HCP?

Hi , I'll answer later on.
4. How to Proof c/a=1.633 in HCP?

I have solved the completely this problem, but your editor does not have the possiblity to draw a picture or triangle and write the equations. If you have any suggestion please let me know. Best regards Kouros Khamoushi
5. How to Proof c/a=1.633 in HCP?

Thank you for your answer. "1. According to you, c/a=1 (posts #5, #12). But also, in the first line of post #12, you write c/a=1.633. Both can not be true." >>We should not forget the homework or question is: "How to Proof c/a=1.633 in HCP?" if this is not true or so that all the given...
6. How to Proof c/a=1.633 in HCP?

C=1.633 a (eq 1). We know a=2R if we substatute this to equation we get C=1.633(2R) which is equal to C= 3.266 . According to your own consumption ""There are so many errors in this. 1. 3a^2 = 32R^2 => a=3.266R (not 1.633R) "" >>Half of a is 1.633R a=3.266R if C=3.266R according to...

"There are so many errors in this. 1. 3a^2 = 32R^2 => a=3.266R (not 1.633R) 2. 8/3 = 2.667 (where did this come from and why did the R disappear?)" >>First of all you forget about a/2 yes a=3.265, but half of it is 1.6329R. R is there and is not disappear. It is the radius of atom...
8. How to Proof c/a=1.633 in HCP?

Thank you for the question. The Hexagonal closed packed structure has 6 corners, because each corner cosists of 1/6 of a sphere and the top and bottom faces each contanins 1/2 of the spheres. Therefore 12(1/6)+2(1/2)+3=6 spheres. Each diagonal has a distance of 2a. The radius of sphere is...
9. How to Proof c/a=1.633 in HCP?

The assumptions above are roughly correct, but we have to take into the considerations the Pythagorean Theorem. The Pythagorean Theorem states: b^2=a^2+c^2. as well as c/2 or half of hexagonal crystal structure as well as the cosine for 30 degree triangles generated by the hole in Hexagonal...

What could happened to heat capacity of solid material if Plank's constant value could be 10 times greater. If Some one knows please help me.
11. Hi do u know anything about fermi zones?

Hello, I look at two books in solid state physics one is Kittel and other Mayer, as well as the internet. Unfortunately, I didn't find any separate word such as (Fermi Zone). I think this is only a level and zone is defined by Brillouin and Fermi is the level which will be define by its spin...
12. Is glass liquid or solid?

Yes, it is right as you mention glass flow, and different type of glasses have their own time limit, but the point is are we taking into the consideration if really glass is solid or not . The answer to this as Myer stated it is counted as solid, but it is still is under question and as I feel...

14. What Is linear algebra like?

Can someone define what is Moduli of elasticity ? The modoli of elasticity Elastic compliance and stifness constants. For example Hook's law state that for small deformations the strain is proportional to the stress, so that strain components are linear functions of the stress components...
15. What Is linear algebra like?

It is very useful subject you use that for all your scientific field in computer science programming and all Engineering and sciences. There are 2 kinds of course in my University one is Linear Algebra, and other is higher rank called Matrix. Which deal with LU decompositions.

17. What Is linear algebra like?

coordinate geometry The study of the geometry of figures by algebraic representation and manipulation of equations describing their positions, configurations, and separations. Analytic geometry is also called coordinate geometry since the objects are described as -tuples of points (where...
18. What Is linear algebra like?

Matt Grime, you are right and that definition is perfect.
19. What Is linear algebra like?

No differential equations is other subject of mathematics. As I have studied both of that, it is simply deals with vectors and vector spaces. It is not really difficult subject, it is very useful and there are a lot of applications where you can use that.
20. What Is linear algebra like?

Hello these equation What are you writing for example: y=x+c y=ax^2+bx+c is belong to subject of Algebra. Regards Kouros
21. What Is linear algebra like?

As I define that the subject of linear Algebra are: It deals with systems of linear equations and matrices. Determinats, Vector space, Real inner product space Linear transformations, Eginvalues, Eginvactors, and Quadratic forms. There are more about matrix and decompositions in higher rank...

This is not Linear Algebra You are talking about NOTICED !!!!! Hello what are you talking about is Algebra not Linear Algebara.
23. Is glass liquid or solid?

Is the glass solid or liquids? It depends in which way one classifying the materials. For example one can say that there are crystalline, amorphous inorganic and organic materials in this case we are concerning with crystal structure of the materials. In crystalline solids the atoms are...
24. Is glass liquid or solid?

Is glass liquide or Solid? At the page 1 of Introductory Solid State Physics Second by H.P. Myers states that: From the present point of view, solid state physics is mainly the physics of crystalline solids. Most of the inorganic solids we encounter in our daily lives are crystalline, the...

c/a + 1.6333 This is the mathematical calculation ^ means to the power of c/2 = a/2 Then a^2 /2 = c^2/2 a^2 + a^2 ----- = (4R)^2 2 2a^2+a^2 -------------- = 16 R^2 2 3a^2 = 2 *16 R^2 a^2 = 2*16 R^2 ----- 3...
