The Pyramids, Egypt

The Egyptian pyramids are massive monuments with a square base and four triangular sides rising up to a point. There is still a lot of curiosity (and many theories) as to how the pyramids were actually constructed

It is generally believed that the Egyptians began constructing them after 2700 B.C. and that they were built as tombs for the pharaohs. The most well-known (and the largest) pyramids of Egypt are the Pyramids at Giza which are said to be the largest ever built. It’s said that the Great Pyramid at Giza took 23 years to complete, using a work force of around 30,000 people. About 118 pyramids have been identified, and they are popular and intriguing to tourists and home researchers alike.

The Egyptian pyramids are ancient pyramid-shaped masonry structures located in Egypt.

As of November 2008, there are sources citing both 118 and 138 as the number of identified Egyptian pyramids Most were built as tombs for the country's pharaohs and their consorts during the Oldand Middle Kingdom periods.

The earliest known Egyptian pyramids are found at Saqqara, northwest of Memphis. The earliest among these is the Pyramid of Djoser (constructed 2630 BC–2611 BC) which was built during thethird dynasty. This pyramid and its surrounding complex were designed by the architect Imhotep, and are generally considered to be the world's oldest monumental structures constructed of dressed masonry. The estimate of the number of workers to build the pyramids range from a few thousand, twenty thousand, and up to 100,000.  The most famous Egyptian pyramids are those found at Giza, on the outskirts of Cairo. Several of theGiza pyramids are counted among the largest structures ever built.  The Pyramid of Khufu at Giza is the largest Egyptian pyramid. It is the only one of the Seven Wonders of the Ancient World still in existence.

Mining Engineering

Mining engineering is an engineering discipline that involves practice, theory, science, technology, and the application of extracting and processing minerals from a naturally occurring environment. Mining engineering also includes processing minerals for additional value.

Environmental Engineering

Environmental engineers are the technical professionals who identify and design solutions for    environmental problems. Environmental engineers provide safe drinking water, treat and properly dispose of wastes, maintain air quality, control water pollution, and remediate sites contaminated due to spills or improper disposal of hazardous substances. They monitor the quality of the air, water, and land. And, they develop new and improved means to protect the environment.
