PYRAMIDS-III

Image
  THE GIZA PYRAMIDS The Giza Pyramids, which were designed to last forever, have done exactly that. The massive tombs date back to Egypt's Old Kingdom era and were built some 4,500 years ago. In the afterlife, Egypt's pharaohs were supposed to become gods. They built temples to the gods and enormous pyramid tombs for themselves to prepare for the next world, which were stocked with everything a king would need to govern and support himself in the next world. Around 2550 B.C., Pharaoh Khufu began the construction of the first Giza pyramid. His Great Pyramid, which stands 481 feet (147 metres) above the plateau, is the biggest in Giza. Each of the estimated 2.3 million stone blocks weighs between 2.5 and 15 tonnes. Pharaoh Khafre, Khufu's son, erected the second pyramid at Giza in 2520 B.C. The Sphinx, a mystery limestone monument with the body of a lion and the head of a pharaoh, was also part of his necropolis. The Sphinx may serve as a guard for the entire pharaoh's bu...

PYRAMIDS-II

                     PYRAMIDS-II THE EGYPTIAN PYRAMID Myr is the Egyptian word for pyramid. It is inscribed using Gardner Symbol List sign O24. Three more signs are employed as phonetics before the Myr. Myr's meaning is unknown because it solely refers to the constructed thing itself. 'High Place' is a common translation of the word myr. Myr employs the same sign, O24, as Benben, according to graphical analysis. In the Egyptian creation storey, the Benben is the mound of beings that ascended from the abyss. The Egyptian pyramids are masonry constructions that date back to ancient Egypt. At least 118 Egyptian pyramids have been identified, according to sources. During the Old and Middle Kingdom periods, the majority were constructed as tombs for the country's pharaohs and their consorts. Although at least one step-pyramid-like structure has been found at Saqqara, dating to the First Dynasty: Mastaba 3808, which has been attributed to...

PYRAMIDS-I

    PYRAMIDS-I       I n architecture, a pyramid is a colossal building with a rectangular base and four sloping triangular (or occasionally trapezoidal) sides that meet at an apex and are built of or coated with stone or brick (or truncated to form a platform). Pyramids have been erected in Egypt, Sudan, Ethiopia, western Asia, Greece, Cyprus, Italy, India, Thailand, Mexico, South America, and on certain Pacific Ocean islands at different eras. Egypt's, as well as those from Central and South America, are the most well-known. Ancient Egypt's pyramids were funeral structures. They were constructed during a 2,700-year span, beginning with the Old Kingdom and ending with the Ptolemaic era. However, the period beginning with the 3rd dynasty and ending with the 6th (c. 2686–2325 BCE) was when pyramid construction achieved its pinnacle, the pyramid age par excellence. The pyramid was the most common kind of royal mausoleum throughout ancient times. It was never...

CLOUDS-ll

  CLOUDS-ll Tropospheric clouds have the potential to influence global climate change. They may deflect incoming solar rays, resulting in a cooling impact where and when these clouds form, or they may trap longer-wave radiation that reflects back up from the Earth's surface, resulting in a warming effect. The major variables that impact the local heating or cooling of the Earth and the atmosphere are the height, shape, and thickness of clouds. Clouds that develop above the troposphere are too few and too thin to have any impact on global warming. The major source of uncertainty in climate sensitivity is clouds.  Nephology The study of clouds is known as nephology, and it is part of the cloud physics branch of meteorology. The Latin and common techniques for naming clouds at their respective homosphere levels exist. Etymology The name "cloud" comes from the Old English terms clud or clod, which refer to a hill or a pile of stone. Because of the resemblance in appear...

VELOCITY 2

  VELOCITY-II Relative velocity Main article:  Relative velocity Relative velocity  is a measurement of velocity between two objects as determined in a single coordinate system. Relative velocity is fundamental in both classical and modern physics, since many systems in physics deal with the relative motion of two or more particles. In Newtonian mechanics, the relative velocity is independent of the chosen inertial reference frame. This is not the case anymore with  special relativity  in which velocities depend on the choice of reference frame. If an object A is moving with velocity  vector   v  and an object B with velocity vector  w , then the velocity of object A  relative to  object B is defined as the difference of the two velocity vectors: {\displaystyle {\boldsymbol {v}}_{A{\text{ relative to }}B}={\boldsymbol {v}}-{\boldsymbol {w}}} Usually, the inertial frame chosen is that in which the latter of the two mentioned objects ...

CLOUDS

  CLOUDS  What are the clouds exactly? A cloud is an aerosol consisting of a visible mass of minute liquid droplets, ice crystals, or other particles suspended in the atmosphere of a planetary body or comparable space, according to meteorology. What causes clouds to form? When warm, wet air rises and cools, it forms a cloud. Why? Moisture is constantly present in the air. When the sun shines and the temperature rises, puddles, rivers, and the sea evaporate, releasing moisture into the air. When compared to warm air, cool air may contain less moisture. As a result, when warm air containing a lot of moisture cools down, the moisture condenses into little cloud droplets in the air. As it climbs, the air becomes cooler. Because the pressure is lower higher up in the sky, the air expands and cools as it expands. As a result, when moist air rises in the atmosphere, part of the water vapour condenses and forms small cloud droplets. What causes certain clouds to be grey ...
