Note that the Orientation Slice is cut precisely to the (100) before the crystal is rotated and cut at either +.25 degrees and toward the flat, or â.25 degrees and away from the flat (as described in Figure 3).
The era was called the Dark Ages also because we don't have a lot of written sources from that time period, especially from the early part of the dark ages (500 to 800 CE).
Best Answer: Ok.. the dark ages was the histroical time period where humans lived as barbarians and uncivilized without the use of tools before 10,000 B.C.E. (around that). The reason why it was called the dark age was because there was no written evidence/stories/history/events that occurred during the time. That means, we have no possible clue of what historically happened before 10,000 B.C.E. Klg.
