Apparently, the motion of Earth slows

Are you think that the day and night throughout the history of life is always the same? If yes, you are wrong. A day and night are determined based on the time required by the Earth in doing one rotation on its axis turns varies.

Scientists know that variations through decades of research with the technique of 'Very-Long Baseline Interferometry (VLBI)'. In essence, scientists measured a day and night at various locations all the time, then compare them.

1.7 milliseconds per 100 years 

The research results of the VLBI, combined with the fossil-based research, revealing that the Earth's rotation slowed. Because slowing rotation of the Earth is the tidal force of the Moon. The Moon itself increasingly moving away from the Earth.

The study by University of Durham physicists, FR Stephenson and colleagues, LV Morrison, revealed that within 100 years, the speed of rotation of the Earth slows down about 1.7 milliseconds. The time duration is very short. As the comparison, for wink alone takes more than that. However, when accumulated in the long term, the difference can be substantial.

Big difference it would make inaccurate forecasts and measurements. For example, when we want to estimate the peak of the eclipse phenomenon at the time of Babylon in 136 BC. With a rotation variation, resulting from calculation errors can reach 48.8 degrees due to the time difference totaled 11.700 seconds.

A day and night just 23 hours

Evidence that the day and night can be great variations revealed by Daniel MacMillan of the Goddard Space Flight Center, National Aeronautics and Space Administration (NASA).

"At the time of the dinosaurs, Earth completed one rotation for 23 hours, and in 1820, Earth's rotation was 24 hours, 86,400 seconds. Since 1820, the mean solar day increased by about 2.5 milliseconds," he said, as explained on the website of NASA in 2012 ago.

RA Nelson and colleagues stated in a paper "Leap Second, Its History and Possible Future" in volume 38, 2001 of the Metrologia journal reveal more surprising facts. According to them, because the tidal force and other causes, in 2,000 years, the Earth has lost of time about 3 hours.

Leap seconds 

In order to maintain standards at the same time remain in line with what is happening with the Earth, Moon, and Sun, scientists then initiated the leap second in 1972. The concept, the addition or subtraction can even one second at certain times so that time remains in sync with the Earth's rotation.

Leap second itself emerged thanks to advances in the measurement of time, especially the second, more precise with cesium atoms. The year of 2015 is one year that would have a leap second. One second will be added on June 30, 2015.

There are a number of people who want to abolish the leap second because it is technologically inconvenient. For example, create a computer system error. However, other groups, said that the leap second will still need to keep precision time.

In addition, if leap seconds are removed, then, in the long term, major changes will occur in the time believed the change of seasons and others. And NASA predicts that if leap seconds are removed, then, in 500 years, the time on Earth will be different 25 minutes with the real time according to the movement of the Earth's rotation and revolution. *** [EKA | FROM VARIOUS SOURCES | ]

The future car technology mimics the workings of the human brain

The most recent innovation of the automotive world is autonomous car. More recently, Audi re-innovating but not participate to make autonomous car, but to design a car that can think and learn like human beings.

As reported by Speedlux on Monday, June 15, 2015, a car that will be created by Audi will work with computerized technology that simulates the human brain.

To develop this huge and ambitious project, Audi will cooperate with Nvidia, a world-class technology company. The California-based company have helped design the auto piloted driving technology.

The autonomous A7, known as 'Jack,' served as a demonstrator for the artificial intelligence algorithms, programmed into the tablet-sized zFAS driver-assistance control that serves as the brain for managing its autonomous systems.

This technology operates through various camera recording images. These images were analyzed by the processor. The processor is capable of studying objects and distinguish these objects.

The whole process involves terabytes of data and must be completed very quickly, relying on an integrated Nvidia Tegra processor rather than sending the information into the cloud.

While according GTSpirit, the system is so advanced because it has the ability like eyes, nose and mouth. This capability is used to detect and differentiate vehicles and other objects on the street.

One of the key elements of this system are in each trip, the system will continue to process the information. Just like humans, the process of adding data to make the car becomes increasingly 'smart'. *** [EKA | FROM VARIOUS SOURCES | LEFTLANENEWS]

Revealed, Venus has active volcanoes

Scientists have long believed that Venus has volcanoes that are still active. Analyzed data collected by the Venus Express spacecraft, scientists now prove that the second closest planet from the Sun it does have volcanoes.

"We have seen a number of events in which the spots on the surface of Venus suddenly heats up and cools down," said Eugene Shalygin of the Max Planck Institute for Solar System Research.

The Venus Express orbiter has found the best evidence yet for volcanic activity on Venus. The researchers based their finding on tell-tale hot spots on Venus' surface. Pictured is an artist's impression. (Picture from: http://dailym.ai/1GukaE0)

There are four spots were detected scientists. Previously, scientists have known that itru spot is a region of volcanoes. However, this is the first time scientists succeeded in proving that the spot could experience significant temperature changes.

"It is the most strongest evidence today about volcanism on Venus," said Shalygin as quoted by the Daily Mail on Friday, June 18th, 2015.

Radiating our from the Venusian volcano Ozza Mons (red, center) are thousands of miles of rift zones (purple). Data from the Venus Express spacecraft suggests there are active lava flows in hotspots along the rifts. (Picture from: http://dailym.ai/1GukaE0)

In the spot called "Object A" which covers only about 1 square kilometer, scientists know that the temperature can reach 830 degrees Celsius, much higher than the usual temperature around 480 degrees Celsius.

Results of this study are consistent with other data from Venus Express showing signs of volcanism on Venus recently.

This Infographic provides key pieces of evidence that can be explained by recent volcanic activity on Venus.  Scientists believe Venus' volcanoes covered the planet in a cataclysmic flood of lava around half a billion years ago - and they believe these volcanoes may still be active today. (Picture from: http://dailym.ai/1GukaE0)

In 2010, a number of mountain infrared image taken by Venus Express indicates that lava once flowed from thousands to millions of years ago. A few years later, there was a surge of sulfur in the atmosphere of Venus that could be a clue that an active central volcano.

"Our study shows that Venus, our nearest neighbor, is still active and changed at this time. This step is important to understand the differences in evolutionary history of Earth and Venus," said Shalygin. *** [EKA | FROM VARIOUS SOURCES | DAILY MAIL]

Nepal earthquake shifted Mt. Everest by 3 centimeters

7.9-magnitude earthquake that rocked Nepal on Saturday, April 25, 2015 not only destroyed the Kathmandu valley and finish more than 8,000 lives. The devastating earthquake also shifted Mount Everest or Qomolangma - the Chinese language - as far as 3 cm to the southwest.

But not until the Nepal quake impact on the world's highest peak, which rises as high as 8,848 meters. Similarly, according to the Agency for Survey, Mapping and Geological Information China.

Chinese media reports, the Beijing government has long put a satellite monitoring system at the top of Everest, since 2005, to monitor the movement of the mountain. A decade later known Everest moves 40 cm to the northeast at a speed of 4 cm per year, and the higher of 0.3 cm per year.

"Mount Everest constantly moving to the northeast. And the earthquake made it bounced slightly in the opposite direction," said Xu Xiwei, deputy head of the Institute of Geology, China Earthquake Administration, Beijing was quoted as saying on the China Daily website. "The scale of these movements are normal and do not affect life there."

However, the earthquake that occurred last April reversing the movement of the mountain - to the point where he was 9 months earlier. When the incident, it triggered landslides in the mountains and surrounding areas, in the border region Nepal and China, claimed the lives of many climbers.

Death in large numbers to force a number of tour providers ascent to the highest mountain in the Himalayas cancel the trip for the rest of the season. Recent data from China shows, the second major earthquake that occurred on April 12, with the power of 7.5 SR did not disturb Everest.

The findings of a team of Chinese experts argue that analysis of a number of experts predict earthquakes, Everest may be shifted up to a few meters in the quake Nepal. But predictions of seismologists confirmed that the height did not change the truth.

Located on the border of China and Nepal, the mountain is also known as Sagarmatha by residents of Kathmandu Valley were in meetings Eurasian and Indian tectonic plates.

"By measuring movements, scientists can learn the principles of how the Earth's energies and carve-scale release of energy released," said Xu.

"These measures help us find the source of tectonic movements and observe when abnormal movements occur." *** [EKA | FROM VARIOUS SOURCES | CHINA DAILY]

The glorious history of Ferrari getting bounced when the manufacturer decided to join the Formula 1 arena. It confirms how great their cars in terms of technology and speed. Well, from the number of Ferrari cars that have been produced to date, it turns out there are only 10 Ferrari supercars were named the best in the history of Ferrari.

Of course the 10 Ferrari cars should be remembered by all automotive lovers, especially Ferrari lovers. And those inauguration of course in terms of design, technology, toughness and the ability to run over the asphalt.

Well, here are the second part of 10 Ferrari coolest cars throughout history.

6. Ferrari F40

The cars manufactured in between 1987-1992 and Ferrari called it the fastest and most powerful car. Imagine this car became the fastest street-legal car to tread on the streets at that time.

8. Ferrari F50

These cool cars were made in the period 1995-1997 which is the result of the development of the F40. Its engine is claimed as the best performing Ferrari's engine. Cars that use a V12 engine that has a capacity of 4,700 cc and can boosted the power up to 513 hp at 8,000 rpm. This car can run up to a maximum speed of 200 mph, thanks to the lightness of its chassis are adopting the Formula 1 technology.
