Scarab Beetle of Ancient Egypt, mystery and use in spells

For the ancient Egyptians the common scarab beetle, Scarabaeus sacer, was a daily reminder of KHEPRI, the manifestation of the sun god RE in the early morning. Khepri's job was to help the rising Sun journey across the sky each day, and he is often portrayed as a beetle rolling the Sun in front of him. The Egyptians noticed that the scarab beetles rolled balls of dung along the ground, and they saw this as an analogy for the Sun moving across the sky.

Refractor or Reflector, for Deep Sky Photography

If you target for faint deep sky imaging, then you will need a very good quality optics, and these come in two main designs, refractors and reflectors. Refractors are the ones with the main objective lens at the front, reflectors counts on a big light-collecting mirror and come in several different configurations. So here's your first big decision, refractor or reflector, and what size?

Literacy in Ancient Egypt

Most people in ancient Egypt did not know how to read and write. Since the majority of Egyptians were peasant farmers, they would not have needed to learn to read, and the complexities of the written language would have made it more difficult to learn than most alphabetic writing systems.

The ancient Egyptians spoke a language which called now "Egyptian". No one exactly knows the correct pronunciation of this language, which in any event changed greatly over the course of several thousand years (as did the written language), and maybe there were regional dialects and variations in pronunciation as well.

Curiosity Mission in Pictures, Part 3: Launch Prepare & Take Off

On April 2004, the United States National Aeronautics and Space Administration (NASA) called for scientific experiments and instruments proposals for a planned Mars Science Laboratory rover mission. Launch was proposed for September 2009. Eight proposals were selected, including instruments from Russia and Spain. Testing of components also began in late 2004, including Aerojet's monopropellant engine with the ability to throttle from 15–100 percent thrust with a fixed propellant inlet pressure.
