Egyptian Pyramids
TheEgyptian pyramidsare ancientpyramid-shaped masonry structures located inEgypt.either 118 or 138 as the number of identified Egyptian pyramids.Most were built as tombs for the country'spharaohsand their consorts during theOldandMiddle Kingdomperiods.
Constructing the pyramids involved moving huge quantities of stone. In 2013, papyri discovered at the Egyptian desert near the Red Sea by archaeologist Pierre Tallet revealed theDiary of Merer, an official of Egypt involved in transporting limestone along the Nile River. These papyri reveal processes in the building of the Great Pyramid at Giza, the tomb of the Pharaoh Khufu, just outside modern Cairo.
Rather than overland transport of the limestone used in building the pyramid, there is evidence—in the Diary of Merer and from preserved remnants of ancient canals and transport boats—that limestone blocks were transported along the Nile River. It is possible that quarried blocks were then transported to the construction site by wooden sleds, with sand in front of the sled wetted to reducefriction. Droplets of water created bridges between the grains of sand, helping them stick together

Egyptian Museum
TheMuseum of Egyptian Antiquities, known commonly as theEgyptian MuseumorMuseum of Cairo, inCairo, Egypt, is home to an extensive collection ofancient Egyptianantiquities. It has 120,000 items, with a representative amount on display, the remainder in storerooms. Built in 1901 by theItalianconstruction company Garozzo-Zaffarani to a design by the French architect Marcel Dourgnon, the edifice is one of thelargest museumsin the region. As of March 2019, the museum is open to the public. In 2021 the museum is due to be superseded by the newGrand Egyptian MuseumatGiza

American life style
TheAmerican way of lifeor theAmerican wayrefers to the Americannationalist ethosthat adheres to the principle oflife, liberty and the pursuit of happiness. At the center of the American way is theAmerican Dreamthat is achievable by any American through hard work. This concept is intertwined with the concept ofAmerican exceptionalism, the belief in the unique culture of the nation. The American Way of life is individualistic, dynamic, and pragmatic. It affirms the supreme value and dignity of the individual; it stresses incessant activity on his part, for he is never to rest but is always to be striving to "get ahead"; it defines an ethic of self-reliance, merit, and character, and judges by achievement: "deeds, not creeds" are what count. The "American Way of Life" is humanitarian, "forward-looking", optimistic. Americans are easily the most generous and philanthropic people in the world, in terms of their ready and unstinting response to suffering anywhere on the globe. The American believes in progress, in self-improvement, and quite fanatically in education. But above all, the American is idealistic. Americans cannot go on making money or achieving worldly success simply on its own merits; such "materialistic" things must, in the American mind, be justified in "higher" terms, in terms of "service" or "stewardship" or "general welfare"... And because they are so idealistic, Americans tend to be moralistic; they are inclined to see all issues as plain and simple, black and white, issues of morality.

Ocean continues waves
Ocean water is constantly in motion: north-south, east-west, alongshore, and vertically. Seawater motions are the result of waves, tides, and currents (Figure below). Ocean movements are the consequence of many separate factors: wind, tides, Coriolis effect, water density differences, and the shape of the ocean basins. Water movements and their causes will be discussed here.
Ocean waves transfer energy through the water over great distances.
seismic waves traveling through the planet, sound waves traveling through seawater, and ocean waves eroding beaches. Waves transfer energy and the size of a wave and the distance it travels depends on the amount of energy that it carries.

Wonderful Sea shore
Thecoast, also known as thecoastlineorseashore, is defined as the area where land meets the sea or ocean, or as a line that forms the boundary between the land and theoceanor alake. Coasts are important zones in natural ecosystems, often home to a wide range of biodiversity, and important zones such as wetlands which are important for bird populations ormangrovesorseagrasswhich providenursery habitatfor fish or other aquatic species. Some coasts fronts on the open ocean and are calledpelagiccoastwhile other coasts are more sheltered coast in agulforbay. Ashore, on the other hand, may refer to parts of land adjoining any large body of water, including oceans (seashore) and lakes (lake shore).

AMERICAN HISTORY and NATIVE AMERICANS
It is not definitively known how or when Native Americans firstsettled the Americasand the present-day United States. The prevailing theory proposes that people fromEurasiafollowedgameacrossBeringia, aland bridgethat connectedSiberiato present-dayAlaskaduring theIce Age, and then spread southward throughout the Americas. This migration may have begun as early as 30,000 years agoand continued through to about 10,000 years ago, when the land bridge became submerged by the rising sea level caused by the melting glaciers. These early inhabitants, calledPaleo-Indians, soon diversified into hundreds of culturally distinct nations and tribes.
Thispre-Columbian eraincorporates allperiodsin thehistory of the Americasbefore the appearance of European influences on the American continents, spanning from theoriginal settlementin theUpper Paleolithicperiod toEuropean colonizationduring theearly modern period. While the term technically refers to the era beforeChristopher Columbus' voyage in 1492, in practice the term usually includes the history ofAmerican indigenous culturesuntil they were conquered or significantly influenced by Europeans, even if this happened decades or centuries after Columbus's initial landing.

AMERICAN HISTORY & NATIVE AMERICANS
Thehistory of the United Statesstarted with the arrival of Native Americans in North America around 15,000 BC.Numerous indigenous culturesformed, and many disappeared in the 1500s. The arrival ofChristopher Columbusin 1492 started theEuropean colonization of the Americas. Most colonies were formed after 1600, and the early records and writings ofJohn Winthropmake the United States the first nation whose most distant origins are fully recorded.

Salah Al-Din Al-Ayoubi Castle in Cairo, Egypt
Salah Al-Din Al-Ayoubi Castle in Cairo, Egypt
Citadel of Cairois a medievalIslamic-era fortification inCairo,Egypt, built bySalah ad-Din(Saladin) and further developed by subsequent Egyptian rulers. It was the seat of government in Egypt and the residence of its rulers for nearly 700 years from the 13th to the 19th centuries. Its location on a promontory of theMokattam hillsnear the center of Cairo commands a strategic position overlooking the city and dominating its skyline. At the time of its construction, it was among the most impressive and ambitious military fortification projects of its time. It is now a preserved historic site, including mosques and museums.

Fhe Fetus, when the wonderful life begin
Fhe Fetus, when the wonderful life begin.
In humans, the fetal stage starts nine weeks after fertilization. At the start of the fetal stage, the fetus is typically about 30 millimetres (1.2in) in length fromcrown-rump, and weighs about 8grams. The head makes up nearly half of the size of the fetus. Breathing-like movements of the fetus are necessary for the stimulation oflung development, rather than for obtaining oxygen.The heart, hands, feet, brain and other organs are present, but are only at the beginning of development and have minimal operation.The genitalia of the fetus starts to form and placenta becomes fully functional during week 9.
At this point in development, uncontrolled movements and twitches occur as muscles, the brain, and pathways begin to develop.

The Magic of Fire
The control of fire by early humans was a turning point in the technological evolution of human beings .
Fire provided a source of warmth and lighting , protection from predators (especially at night), a way to create more advanced hunting tools, and a method for cooking food. These cultural advances allowed human geographic dispersal, cultural innovations, and changes to diet and behavior. Additionally, creating fire allowed human activity to continue into the dark and colder hours of the evening.

Landscape over the River
Landscape design focuses on both the integrated master landscape planning of a property and the specific garden design of landscape elements and plants within it. The practical, aesthetic , horticultural , and environmental sustainability are also components of landscape design, which is often divided into hardscape design and softscape design. Landscape designers often collaborate with related disciplines such as architecture, civil engineering ,
surveying , landscape contracting , and artisan specialties.

The Speedy Clouds
In meteorology, a cloud is an aerosol consisting of a visible mass of minute liquid droplets , frozen crystals , or other particles suspended in the
atmosphere of a planetary body or similar space.
Water or various other chemicals may compose the droplets and crystals. On Earth , clouds are formed as a result of saturation of the air when it is cooled to its dew point , or when it gains sufficient moisture (usually in the form of water vapor ) from an adjacent source to raise the dew point to the ambient temperature

The other side of the Moon
The far side of the Moon is the lunar hemisphere that always faces away from Earth , as opposed to the opposite near side . Compared to the near side, the far side's terrain is rugged, with a multitude of impact craters and relatively few flat and dark lunar maria ("seas"). It has one of the largest craters in the Solar System , the South Pole–Aitken basin . The hemisphere is sometimes called the "dark side of the Moon ", where "dark" means "unknown" instead of "lacking sunlight" – both sides of the Moon experience two weeks of sunlight while the opposite side experiences two weeks of night.

The Bridge over the River
The Bridge over the River.
Bridge , structure that spans horizontally between supports, whose function is to carry vertical loads. The prototypical bridge is quite simple—two supports holding up a beam—yet the engineering problems that must be overcome even in this simple form are inherent in every bridge: the supports must be strong enough to hold the structure up, and the span between supports must be strong enough to carry the loads. Spans are generally made as short as possible; long spans are justified where good foundations are limited—for example, over estuaries with deep water.

The long vehicle
Did you know your car’s front tires carry about 60% of the vehicle’s weight? In addition, they are also more likely to feel hard turns. Regularly rotating your tires evens out the tread wear acquired by daily driving, thus lengthening the life of the tires.

seismic waves traveling through the planet, sound waves traveling through seawater, and ocean waves eroding beaches. Waves transfer energy and the size of a wave and the distance it travels depends on the amount of energy that it carries.
This studies the most familiar waves, those on the ocean’s surface. Ocean waves originate from wind blowing – steady winds or high storm winds – over the water. Sometimes these winds are far from where the ocean waves are seen.

The Citadel
Acitadelis the core fortified area of a town or city. It may be acastle,fortress, or fortified center. The term is a diminutive of "city" and thus means "little city", so called because it is a smaller part of the city of which it is the defensive core.Ancient Spartahad a citadel, as did many otherGreekcities and towns.
In afortificationwithbastions, the citadel is the strongest part of the system, sometimes well inside the outer walls and bastions, but often forming part of the outer wall for the sake of economy. It is positioned to be the last line of defense, should the enemy breach the other components of the fortification system. The functions of the police and the army, as well as the armybarrackswere developed in the citadel.

Nature and Chick Life.
Chicks life is very important.
France is to ban the controversial practice of shredding live male chicks by the end of 2021.
Billions of male chicks are culled around the world by industrial farmers as they areconsidered redundantby both egg and poultry producers.
Egg producers use cockerels only for insemination while poultry producers favor hens for meat, as they grow faster.

City cars movements 🚗 🚘 🚔 🏎 🚓 🚕 🚗
Car parking is of central importance to congestion on roads and the urban planning process of optimizing road networks, pricing parking lots and planning land use. The efficient placement, sizing and grid connection of charging stations for electric cars makes it even more important to know the spatio-temporal distribution of car parking densities on the scale of entire cities. Here, we generate car parking density maps using travel time measurements only. We formulate a Hidden Markov Model that contains non-linear functional relationships between the changing average travel times among the zones of a city and both the traffic activity and flow direction probabilities of cars. We then sample the traffic flow for 1,000 cars per city zone for each city from these probability distributions and normalize the resulting spatial parking distribution of cars in each time step.

Wonderful landscape
Geometric roadway design can be broken into three main parts: alignment, profile, and cross-section. Combined, they provide a three-dimensional layout for a roadway.
The profile of a road consists of road slopes, called grades, connected byparabolicvertical curves. Vertical curves are used to provide a gradual change from one road slope to another, so that vehicles may smoothly navigate grade changes as they travel.
Sag vertical curves are those that have a tangent slope at the end of the curve that is higher than that of the beginning of the curve. When driving on a road, a sag curve would appear as a valley, with the vehicle first going downhill before reaching the bottom of the curve and continuing uphill or level.
Crest vertical curves are those that have a tangent slope at the end of the curve that is lower than that of the beginning of the curve. When driving on a crest curve, the road appears as a hill, with the vehicle first going uphill before reaching the top of the curve and continuing downhill.
Thealignmentis the route of the road, defined as a series of horizontal tangents and curves.
Theprofileis the vertical aspect of the road, including crest and sag curves, and the straight grade lines connecting them.
Thecross sectionshows the position and number of vehicle and bicycle lanes and sidewalks, along with their cross slope orbanking. Cross sections also show drainage features, pavement structure and other items outside the category of geometric design.

Wonderful Roads design
Thegeometric design of roadsis the branch ofhighway engineeringconcerned with the positioning of the physical elements of the roadway according to standards and constraints. The basic objectives in geometric design are to optimize efficiency and safety while minimizing cost and environmental damage. Geometric design also affects an emerging fifth objective called "livability," which is defined as designing roads to foster broader community goals, including providing access to employment, schools, businesses and residences, accommodate a range of travel modes such as walking, bicycling, transit, and automobiles, and minimizing fuel use, emissions and environmental damage.

The Big mistake President Donald Trump.
What is happening now in the United States can be understood by everyone who has a mind. It is a destruction of the constitution and all laws in the United States. It is the encouragement of some groups against others. It is not a call to freedom or the rejection of persecution, but it falls as the trouble makers and the encouragement of unrest.
Supporters of President Donald Trump have breached the US Capitol as lawmakers attempted to count the Electoral College votes certifying President-elect Joe Biden's win, and an armed standoff is taking place outside the House of Representatives.
Shortly after 1 p.m. ET hundreds of pro-Trump protesters pushed through barriers set up along the perimeter of the Capitol, where they tussled with officers in full riot gear, some calling the officers "traitors" for doing their jobs. About 90 minutes later, police said demonstrators got into the building and the doors to the House and Senate were being locked. Shortly after, the House floor was evacuated by police.
An armed standoff was taking place at the House front door as of 3 p.m. ET, and police officers had their guns drawn at someone who is trying to breach it. A Trump supporter was also pictured standing at the Senate dais.
Vice President Mike Pence was also evacuated from Capitol, where he was to perform his role in the counting of electoral votes.
Video from inside the Capitol showed Trump supporters marching through Statuary Hall. The US Capitol Police is asking for additional law enforcement for assistance, including federal authorities, per a source familiar.
The source says there are several suspicious devices outside the Capitol building.
The Capitol police officer in the House chamber told lawmakers that they may need to duck under their chairs and informed lawmakers that protesters were in the building's Rotunda.
While the White House refused to comment on the protests, Trump said on Twitter, "Please support our Capitol Police and Law Enforcement. They are truly on the side of our Country. Stay peaceful!"
The protesters have breached exterior security barriers, and video footage shows protesters gathering and some clashing with police near the Capitol building. CNN's team on the ground saw a number of protestors trying to go up the side of the Capitol building. Several loud flash bangs have been heard.
Protesters could be seen pushing against metal fences and police using the fences to push protesters back, while other officers reached over the top to club people trying to cross their lines.
Flash bangs could be heard near the steps of the Capitol as smoke filled the air. In some instances officers could be seen deploying pepper spray. Tear gas has been deployed, but it's not clear whether by protesters or police, and people wiped tears from their eyes while coughing.
Washington Mayor Muriel Bowser just announced a citywide curfew from 6 p.m. ET on Wednesday until 6 a.m. ET Thursday.
Federal and local law enforcement are responding to reports of possible pipe bombs in multiple locations in Washington DC, according to a federal law enforcement official. It's unclear if the devices are real or a hoax, but they're being treated as real.
