meme stolen from a couple of people
1. Grab the nearest book.
2. Open the book to page 123.
3. Find the fifth sentence.
4. Post the text of the next 3 sentences on your LJ along with these instructions.
5. Don’t you dare dig for that "cool" or "intellectual" book in your closet! I know you were thinking about it! Just pick up whatever is closest.
"In (a), for example, the cell was said to contain only one atom, but the shape of the cell was not specified; in (b) and (c), the cells were described as orthorhombic and in (d) as cubic, but this information did not enter into the structure factor calculations. This illustrates the important point that the structure factor is independent of the shape and size of the unit cell. For example, any body-centered cell will have missing reflections for those planes which have (h + k + l) equal to an odd number, whether the cell is cubic, tetragonal, or orthorhombic."
Sadly enough the closest book was actually a textbook. Woe is me.
