Mysterious Chamber Discovered in Egyptian Pyramid

A mysterious chamber in an  Egyptian pyramid has been recently discovered by scientists. A special technique shows a  large void hidden in the Great Pyramid of Giza  near Cairo

The ScansPyramid project, led by the University of Cairo and the Egyptian government,  uses advanced technology to find out more about ancient structures. Scientists from Egypt, France and Japan installed special detectors which could detect small particles called muons. These are a type of cosmic rain which constantly falls down on the earth. Three separate teams have conducted the research and have found the same cavity in the pyramid.

The newly found chamber in the Egyptian pyramid is 30 metres long and about the size of the Grand Gallery which is a known passageway that leads to the King’s Chamber. However, nothing else is known about the new room. It is also impossible to reach the space as there is no passage that leads to it. Experts also warn against having great expectations about new discovery inside the cavity.  It is possible that the void does not have any meaning at all and was just left there for construction reasons.

The Great Pyramid, also known as the Pyramid of Khufu, was built at around 2650 BC. after the death of the pharaoh. It is the largest of the three remaining pyramids at Giza, which belong to the wonders of the ancient world.

Google Maps Navigates Through Solar System

In addition to finding any place on Earth,  Google Maps now lets you navigate through space too.  It has recently added two dwarf planets, Pluto and Ceres, as well as some of the moons of Venus, Saturn and Jupiter  to its service.

Users can now explore the surface of Titan, Saturn’s largest moon . You can see lakes and rivers of methane beneath its clouds . About half a million images  come from the Cassini mission ,which  explored Saturn and its moons for  15 years before it burned up in the planet’s atmosphere.

Other highlights include close-ups of Saturn’s sixth-largest moon Enceladus , where water was discovered beneath the surface. Jupiter’s moons Europa and Ganymede are also included in Google Map’s new version. A total of 16 planets and moons can now be explored by users.

Exploring space  works like any place on Earth would.  Just choose a planet or moon and zoom around. Google Map offers the most important physical features of each celestial body as well as corresponding names.

Google Maps started out as a service that let users navigate land . In the past, years the world’s oceans have been added to the map service and in 2014 Google added images of our moon and Mars. Since 2017 users can take a tour of the International Space Station. Most of the material comes from various explorations carried out by NASA and the European Space Agency (ESA).

Sidewalk Toronto – City of the Future in Canada

Sidewalk Labs, a Google company, has announced  plans to build a futuristic city in Toronto, Canada. The new urban area, called Sidewalk Toronto, aims at turning the waterfront of Lake Ontario into a playground for city development and a testing site  for new technologies.

The project wants to make cities cheaper, healthier and even more exciting to live in .  The new city will offer its residents ultra-fast WiFi connections, lanes for self-driving cars and sustainable energy sources.  Thousands of sensors will report pollution and noise levels, as well as monitor traffic and levels of carbon monoxide.

Planners of Sidewalk Toronto want to find new solutions for  overpopulation, waste management , traffic , pollution and other urban problems. Several companies have said that they will make their services  available to the new city. 

Planners estimate that the project will cost around 1 billion dollars. However, it will also offer tens of thousands of people a place to live, work  and have fun. Eventually, similar projects may spread to other parts of the world, helping to build smarter and greener  cities.

Google has also announced that it plans to move its Canadian headquarters to Sidewalk Toronto.

Estonia – A Digital Society

Estonia is a small Baltic state with a population of 1.3 million. Despite its size it is one of the most technologically advanced countries in the world and has been creating a digital society since the collapse of the Soviet Union in 1991.

In Estonia, citizens are allowed to do most things online.  Every inhabitant has a unique ID card that they use for a number of purposes.They can file tax returns, get medical prescriptions  and manage their health records online. They can pay for a parking ticket via mobile phone and don’t have to go to a registration office when a child is born. Parents can check their children’s grades  and communicate with teachers. For many years Estonians have been able to vote online.

In 2014 the small Baltic country started a new digital initiative. It allows non-citizens to become digital residents for 100 euros. The government wants to bring qualified people to the country because the working population is steadily decreasing. The country desperately needs new programmers, web developers and media experts. Up to now 20 000 people from other countries have applied for digital citizenship.

Many countries, among them Finland and Japan are trying to copy Estonia’s digital society. However, authorities point out that the country’s smallness is an advantage. Such a system may not work very well in larger countries with millions of people.

Ocean Wind Farms Could Give Energy To Everybody

Winds and storms in the Atlantic are so strong that wind-powered turbines in the Atlantic Ocean could provide the whole world with clean energy. Energy experts now claim that ocean wind farms  can produce three to five times more energy than wind turbines on land. Over water wind speeds are up to 70% higher.

Winds on land create friction because of mountains and buildings. They slow down as they move inwards . In addition, turbines are built closer together, which takes some of the wind speed away .

Winds are especially strong across the northern Atlantic Ocean because of differences in water temperature. When the warm Gulf Stream moves up the North American coast it mixes with cold water in the northern Atlantic. This leads to higher storm activity and more winds, especially during the winter months.

Norway’s energy company Statoil has been operating floating wind turbines in the shallow North Sea for over a decade. These are connected via cable to the ocean floor.  In order to make them work  in the deep sea , however, they must be attached to vertical poles that have massive weights in the water.

One of the biggest problems that face ocean wind farms is transporting energy from the deep sea to land. Energy companies , like Statoil, are looking for high-wind areas that are closer to shore.

While wind farms on land are becoming more  and more common, production costs of running them are becoming lower. In the near future wind energy is expected to become one of the cheapest alternative energy sources .

Europe is the number one wind energy producer at the moment. Every year, about 12 gigawatts of energy are produced by wind power, whereas in America green energy from wind is still in its infancy. If  produced more effectively, the solution to the world’s energy problems may lie in ocean wind farms.

60 Years Ago – Sputnik First Satellite in Space

60 years ago , on October 4th, 1957, the Soviet Union  launched the first man-made satellite into space. Sputnik showed that the Soviets were willing to overtake American technology.  The launch was also the beginning of a new episode in the Cold War – the Space Race.

Sputnik looked like a big basketball and weighed 84 kilograms. Two radio transmitters  and four antennae were attached to it. The satellite sent out a beeping signal and could be seen on Earth with the naked eye.

The Soviet satellite orbited the Earth over 1,400 times in a period of three months before it burned up in the atmosphereA month later Sputnik 2 was launched, this time with the first animal on board, a dog named Laika.

Sergei Korolev was the father of the Soviet space program. He oversaw the creation of a booster rocket that sent Sputnik into orbit. Korolev was also responsible for bringing  German engineers to the Soviet Union after World War II.

While Sputnik took the rest of the world by surprise, the Soviet Union told their people about the historic launch only a few days later.

In January 1958 the Americans were able to launch their first satellite into orbit. Explorer I  remained in orbit until 1970 and was the  first satellite to detect the Van Allen radiation belt.  Later that year Congress passed a law that created NASA , the American space agency.
