Why is the mouse cursor slightly tilted and not straight?

The mouse, and therefore the mouse cursor, was invented by Douglas Englebart, and was initially an arrow pointing up.
When the XEROX PARC machine was built, the cursor changed into a tilted arrow. It was found that, given the low resolution of the screens in those days, drawing a straight line (left edge of arrow) and a line at a 45 degree angle (right edge of arrow) was easier to do and more recognizable than the straight cursor.

4,600-Year-Old Step Pyramid Excavated in Egypt

 

 

Archaeologists working near the ancient settlement of Edfu, in southern Egypt, have uncovered a step pyramid that dates back about 4,600 years, predating the Great Pyramid of Giza by at least a few decades.
The step pyramid, which once stood as high as 43 feet (13 meters), is one of seven so-called "provincial" pyramids built by either the pharaoh Huni (reign ca. 2635-2610 B.C.) or Snefru (reign ca. 2610-2590 B.C.). Over time, the step pyramid's stone blocks were pillaged, and the monument was exposed to weathering, so today, it's only about 16 feet (5 m) tall.
