Humans are not superior, dolphins are smarter!

People are not the smartest creatures on Earth, scientists say, and that some species of animals, in their own way, are more intelligent - for example dolphins.

Killer whales have a complex language to communicate , and dolphins give each other the names that are based on the sound signal. This means that dolphins are finding themselves and others, say the scientists .
For thousands of years, various experts , from religious leaders to scientists , saying that people are "special and the brightest " , but science shows that some animals have the cognitive skills that more  superior human beings .
Researchers from the University of Adelaide once confirmed this thesis , a intelligence research and the evolution of primate brain supports the hypothesis that people are not the smartest creatures on Earth .
Scientists remind us that Aristotle , one of the greatest thinkers , argued that humans are superior to other animals because of their reasoning skills . But the reasoning is only one form of intelligence . The fact is that people do not understand the animals and they do not understand people , but that does not mean that their intelligence at different levels , but only that - a different kind.
People have a cumulative culture , which allows them to perform many of the actions that other animals can not do . However , this does not mean that the individuals of the human race superior to other beings.
" Monkeys are built in such a way that they do not need a house , people have evolved in an environment where you do not have to hand catch fish , but the Bears have , and they do it better than men ," the researchers said.

It would only take 29 dominoes to knock over the Empire State Building

Physics can be terrifying and awesome at the same time. A single, tiny domino, only five millimeters high and a single millimeter thick could knock down a building as big as the Empire State building in just 29 steps.

Dominoes can knock over another domino up to one and a half times it's size. If you started with that small domino, about the size of a fingernail, it would only take 29 dominoes, each one one and a half times larger than the previous, to get to the size of New York's crown jewel building—and it would crumble.

Gravitational energy is stored in each domino when they are stood up, which requires just the slightest push to get the energy to spill to the side and release that energy that goes straight into the next domino it hits. With every domino the energy continues to amplify, gaining the power to knock down just about anything in it's way once it gets big enough.

The idea of massive amounts of energy getting exponentially bigger can be a terrifying thought on a grand scale.

Star slightly younger than the Universe

Australian astronomers, during the project mapping parts of the southern sky, discovered Star SM0313, whose age is estimated at about 13.6 billion years, only a few hundred million years younger than the age of the Universe.


One of the very important information about the objects in the universe that spectroscopy reveals is their age. Australian astronomers , during the project mapping parts of the southern sky discovered Star SM0313 , located less than 2 kiloparseka of the solar system ( the diameter of our galaxy , the Milky Way is about 30 kiloparseka ) . After precision spectroscopic observations 6.5 meter Magellan telescope in Chile , and the stars age is estimated at about 13.6 billion years. Only a few hundred million years younger than the age of the Universe .
Indicator of great age, and the stars is that its range is such that points to the almost complete absence of elements heavier than hydrogen and helium . For example, the proportion of iron in the composition of these stars is ten million times smaller than the fraction of iron in the composition of the Sun . This points to the fact that , at the time when these stars formed in the universe was much less heavy elements than today . How heavy elements are formed in the evolution of stars and are dispersed throughout the universe in supernova explosions , this is an indicator of the extreme age of the stars SM0313.

The process of determining the chemical composition of the stars on the basis of the spectrum and its age on the basis of chemical composition is the result of an extremely successful and detailed theoretical analysis which started greats such as astrophysics S.Čandrasekar , Eddington , E. Salpeter and others. However , believe it or not , this star is not made ​​of intact gas . The share of heavy metals is higher than that which arose in the big bang , so currently we think that these stars formed from material which, upon reaching the stage of a supernova , threw the first stars , known as Population III . Population III stars were made ​​up entirely of hydrogen, helium and lithium, elements that were created in the Big Bang . They , however , have not yet been directly detected .
Evolution of stars, from lighter elements are formed heavier , which are processes in the final stages of the evolution of the stars were scattered into the surrounding interstellar medium . From it are gradually emerged a new star that were richer and richer in heavy elements . Sun , Earth and life as we know it here would not be able to occur without this process of " cosmic recycling . "
Direct detection of population III stars will be one of the main tasks of the James Webb Space Telescope ( JWST ) . Understanding the process of evolution of the first stars is extremely important for the theory of the formation and evolution of galaxies , as well as for better understanding of cosmological processes , such as zoning .

Discovered "oldest" piece of our planet

Small zircon crystal found in Australia is officially the oldest piece of our planet, after scientists using two methods found that it is 4.4 billion years old.

In a paper published in the journal " Nature Geoscience " , a team of researchers said that their findings suggest that the Earth's crust formed relatively quickly after forming the planet .
" The early Earth was not so cruel place as previously thought ," said team leader John Velly , a professor at the University of Wisconsin .
British "Guardian " specifies that our planet formed 4.5 billion years ago , and that this finding means that the crust got pretty quickly - " only " 100 million years later . Age crystals means that the crust occurred only 160 million years after the formation of our solar system .
The discovery supports the theory of " cold sores Earth " where temperatures were low enough that there are oceans and possibly life in them , earlier than previously thought .
" We very interested in the issue when the country became a place suitable for life ? When cool enough to make life could emerge. Age of crystals suggests that our planet might be able to support life at the micro level before 4.3 billion years ," says Velly .
He points out that there is no evidence that life actually existed then , but that there is no evidence to indicate that definitely did not exist.
" There is no reason to say that before 4.3 billion years life could not exist ," he adds .
Officially the oldest fossil that scientists have found a star is about 3.4 billion years ago.
Zircon that could change the view of the history of our planet was found on a sheep farm in the area of ​​Jack Hils in Australia and it is very small . Dimension is about 200x400 microns , twice larger in diameter than a human hair .
" Zircons know they are big and very nice , but those with whom we work are small and not too attractive, except for geologists . When you hold it in your palm , you can see very well , you might be able to encounter a means of quality loupes " says Velly .

Eating Chocolate Can Improve Math Skills

Bad at maths? Gorge on chocolates before you attempt your next examination. A study from a few years back revealed that eating chocolate could improve the brain’s ability to do maths as well as boost your energy level. Researchers carried out the study in 2009 and found that flavanols, compounds found in chocolate and part of a group of chemicals called polyphenols, actually work by increasing the flow of blood into the brain.

According to the study’s lead author David Kennedy of Northumbria University, the findings suggest that students who binge on chocolate when revising for examination might gain a real benefit from doing so and chocolate could be beneficial for mentally challenging tasks also. ‘For things that are difficult to do, mentally demanding things that may crop up in your work it could help,’ Prof Kennedy was quoted as saying.

In the study, 30 volunteers were asked to count backwards in groups of three from a random number between 800 and 999 generated by a computer. The findings showed that they could do the calculations more quickly and accurately after they were given a hot cocoa drink containing 500 mg flavanols. However, the same was not true when the group was asked to count backwards in groups of seven, which the researchers described as a more complex task, requiring a slightly different part of the brain.

 

Computers will in 15 years be smarter than us

Ray Kurtzvail, an expert in artificial intelligence at the company'' Google'', predicts that by the 2029  computers will be smarter than humans. Entrepreneur and futurist, predicted that in the next 15 years, computers will become more intelligent and will be able to understand what you're talking about, learn from experience, joke, tell stories, and even flirt.

Kurtzvail ( 66 ), which is considered one of the world's leading experts in artificial intelligence , and the technologists has popularized his idea of ​​" singularity " - the moment in the future when humans and machines become one.
'' Google '' hired him end of 2012. to work on future projects of the company - a search engine that is used artificial intelligence and knows us better than we know ourselves .
In an interview with the Observer New Review, Kurtzvail says his company has not given any explicit instructions , except that he was ordered to find a way to " teach " Google to understand natural language .
" My project is to start a search for understanding of the language ," he says .
" When you write an article , you do not create an interesting collection of words . You have something to say and ' Google ' should be intelligently organized and processed information from around the world . The message in your article is the information , but that computers do not understand . Therefore , we want them to read everything there is on the internet and each page of each book , so that they could participate in an intelligent dialogue with customers and answer their questions, " he explained.
Kurtzvail predictions are only part of the earlier announcement that Google makes the largest laboratory in the world of artificial intelligence . The company has acquired several companies engaged in " teaching " machines and production of robots , including '' Boston Dynamics '' .
Kurtzvail is known for his inventions that changed the world - the first desktop scanner , the first computer program that is able to recognize the first syllable fonts and speech synthesizer .
It was in 1990. predicted that the computer would beat the world chess champion to in 1998. ( In 1997. IBM 's Deep Blue beat Garry Kasparov ) and the world wide web to be hit and at a time when the network used by a few scientists.

On Titan the atmosphere is so thick and the gravity so low that humans could fly through it by flapping “wings” attached to their arms

Titan is one of the moons on Planet Saturn. It is said that here, the atmosphere is so thick and the gravity so low that you could fly through it like a bird does on Earth by flapping wings attached to your arms. This statement can be found in the book Entering Space: Creating a Spacefaring Civilization by Robert Zubrin.

Of course, the atmosphere on Titan would not be conducive for your health, so a spacesuit could come in handy. The Voyager has been able to make some observations that prove the atmosphere on Titan is denser than Earth’s, and this has been put at about 1.19 times as immense as Earth’s overall.

The lower gravity on Titan implies that the atmosphere extends way much more than Earth’s. This was even proven by the Cassini spacecraft that flying at a distance of 975 km, had to make adjustments to maintain a steady orbit against atmospheric drag.
