Luxor is a city in Upper (southern) Egypt and the capital of Luxor Governorate. The population of Luxor is 127,994 (2020), with an area of approximately 417 square kilometres (161 sq mi). It is among the oldest inhabited cities in the world.
The modern city includes the site of the Ancient Egyptian city of Waset, also known as Nut (Coptic: ⲛⲏ) and to the Greeks as Thebes or Diospolis. Luxor has frequently been characterized as the “world’s greatest open-air museum”, as the ruins of the temple complexes at Karnak and Luxor stand within the modern city. Immediately opposite, across the River Nile, lie the monuments, temples and tombs of the West Bank Necropolis, which includes the Valley of the Kings and Valley of the Queens.
On a mild autumn day in 2016, the Hungarian mathematician Gábor Domokos arrived on the geophysicist Douglas Jerolmack’s doorstep in Philadelphia. Domokos carried with him his suitcases, a bad cold, and a burning secret.
The two men walked across a gravel lot behind the house, where Jerolmack’s wife ran a taco cart. Their feet crunched over crushed limestone. Domokos pointed down.
“How many facets do each of these gravel pieces have?” he said. Then he grinned. “What if I told you that the number was always somewhere around six?” Then he asked a bigger question, one that he hoped would worm its way into his colleague’s brain. What if the world is made of cubes?
At first, Jerolmack objected. Houses can be built out of bricks, but Earth is made of rocks. Obviously, rocks vary. Mica flakes into sheets; crystals crack on sharply defined axes. But from mathematics alone, Domokos argued, any rocks that broke randomly would crack into shapes that have, on average, six faces and eight vertices. Considered together, they would all be shadowy approximations converging on a sort of ideal cube. Domokos had proved it mathematically, he said. Now he needed Jerolmack’s help to show that this is what nature does.
“It was geometry with an exact prediction that was borne out in the natural world, with essentially no physics involved,” said Jerolmack, a professor at the University of Pennsylvania. “How in the hell does nature let this happen?”
I try not to bet on politics; it’s better to gamble on March Madness, the best sporting event in America. But here’s a wager I would make: The two Republican House members from Washington State who voted to impeach former President Donald Trump will not only survive their next election but do even better in 2022 than they did last year.
That’s right: The gutsy stand to remove a mad president will actually help Representatives Jaime Herrera Beutler and Dan Newhouse win re-election, which is how it should be for the rare politician who chooses country over party.
They will win because Washington is one of the few states where voters have designed a method to keep extremists from both parties on the fringe of politics. It’s something the rest of the country could learn from.
In other words, how can we save the Republican Party, now in the midst of a fight over its confused and darkened soul? Take it away from Republican Party activists and give it to the people. We already have a way to make it work.

Denver, officially the City and County of Denver, is the capital and most populous city of the U.S. State of Colorado. Denver is located in the South Platte River Valley on the western edge of the High Plains just east of the Front Range of the Rocky Mountains. With an estimated population of 727,211 in 2019, Denver is the 19th-most populous city in the United States, the fifth-most populous state capital, and the most populous city located in the Mountain states. The metropolitan area surrounding Denver represents a majority of the population and economic activity in the Front Range region, the area where an estimated 85% of Colorado’s population lives. The Denver downtown district is immediately east of the confluence of Cherry Creek and the South Platte River, approximately 12 mi (19 km) east of the foothills of the Rocky Mountains. Denver is named after James W. Denver, a governor of the Kansas Territory. It is nicknamed the Mile High City because its official elevation is exactly one mile (5280 feet or 1609.344 meters) above sea level. The 105th meridian west of Greenwich, the longitudinal reference for the Mountain Time Zone, passes directly through Denver Union Station.

One of the most powerful telescopes in the world is on the brink of collapse.
Arecibo, a giant radio observatory nestled in the lush mountains of Puerto Rico, did some of the dreamiest work in astronomy. But it was forced to stop operations this year after suffering unprecedented damage, and officials now believe that it is beyond repair. Instead of trying to fix it, they’re going to tear it down.
The trouble began in August. A metal support cable weighing thousands of pounds slipped out of its socket and plummeted into the cavernous, 1,000-foot-wide radio dish in the middle of the night. The cable, installed in the 1990s, was considered fairly new for an observatory that began operations in 1963, and the incident confounded Arecibo’s stewards. The cable “definitely should not have failed in the way it did,” Ashley Zauderer, the Arecibo program director at the National Science Foundation,which owns the telescope, said during a press conference today.
Dubai is the most populous city in the United Arab Emirates (UAE) and the capital of the Emirate of Dubai.
Located in the eastern part of the Arabian Peninsula on the coast of the Persian Gulf, Dubai aims to be the business hub of Western Asia. It is also a major global transport hub for passengers and cargo. Oil revenue helped accelerate the development of the city, which was already a major mercantile hub. Dubai’s oil output made up 2.1 percent of the Persian Gulf emirates economy in 2008. A center for regional and international trade since the early 20th century, Dubai’s economy relies on revenues from trade, tourism, aviation, real estate, and financial services. According to government data, the population of Dubai is estimated at around 3,400,800 as of 8 September 2020.
One fascinating quirk of the Universe is that shapes and patterns can be found in hugely different contexts: the Golden Spiral can be seen in the human cochlea and the shape of a spiral galaxy; the fractal geometry of veins echoed in the branching of lightning.
In a bold new pilot study, an astrophysicist and a neurosurgeon have bumped it up a notch, using quantitative analysis to compare two of the most complex systems in nature: the neuronal network in the human brain and the cosmic network of galaxies in the Universe.
It’s actually not that peculiar a comparison. You may have seen an image that occasionally gets shared around, showing a human neuron and a simulated galaxy cluster, side-by-side; the two look startlingly similar.
But there’s a lot more to the human brain – and the Universe – than how it looks.
So astrophysicist Franco Vazza of the University of Bologna in Italy and neurosurgeon Alberto Feletti of the University of Verona in Italy have spent the last few years investigating to determine if the similarities are more than skin-deep.

In the world, human beings are facing various problems. People who are full of greed, anger, and ignorance are seen to be fighting with each other in words and deeds. As the fighting continues, various problems such as civil wars, wars of aggression, and wars of aggression are occurring. As world peace is being destroyed, humans are facing unbearable problems. Innocent children and women are not getting the rights they deserve and deserve. I can't think of one thing every time. What is it? The United Nations. If we look at the responsibilities and duties of the United Nations, I think it is not suitable for solving the problems that are happening in the world today. In fact, the United Nations and the World Security Council, such an organization must rule the world, must be able to give orders, and must have various ways to obey orders. There must be no organization that can influence more than that organization. There should be experts from each country. They can even dominate the superpowers like the US, China, and Britain. Only then will global peace be achieved quickly. Now, if a country with power develops more militarily, economically, or socially than its own country, then powerful countries will jealously seek out enemies and wage war. Or they will attack with fighter jets. In this, innocent people are losing their lives. No one understands the value of a life. You should think about how to achieve global peace by controlling these. If the US continues to be the permanent president of the UN, world peace will never be achieved. If you think carefully, no one sees that they are working for the common good, but for their own benefit, for the benefit of their own country. The permanent president of the UN and the Security Council has rejected this, As a young Rohingya, I have come to realize that only by electing the president and secretary from among the countries in the world through a secret ballot system and governing the world fairly can we achieve global peace. The United Nations and the Security Council are organizations in which any country must govern, give orders, and make them obey their orders. For example, only when a defendant is tried in court can we hold the leaders of the countries in check and control them, can we achieve global peace smoothly. Otherwise, it will not be easy for powerful countries to use various excuses to end this war every year, every year, for the benefit of themselves and their countries. No country's leaders pay any attention to the words of the United Nations and the Security Council. If we look at it in practice, look at the Rohingya issue. Myanmar is a small country. Even that country has been under siege for 8 years. What action can be taken? Why is the UN and the Security Council Powerless? Without such Power, how can the organization bring about global peace? Everyone should think about it. Whether there is a veto or a strong one, all countries in the world can only achieve global peace if they are subject to the UN and the Security Council. Seek peace in the quiet embrace of nature. Peace is an indispensable need of the human race. It is not as if one person can kill another person, and it is as if one country can attack another country, but instead of trying to build peace, we must try to destroy the peace now, and the world is getting hotter and is on the verge of collapse. I especially appeal to all the world experts to urgently try to bring about peace in all parts of the world. Mr, Noor Muhamed Arkhan Rohingya Youth Myanmar
