We like aggressive music – Strong, sad, full of emotions
We like aggressive music – Strong, sad, full of emotions – We are more willing to choose sad, troubling and full of anger songs. This phenomenon was observed by analysts from Lawrence Technological University. They used an automated system to evaluate the lyrics of the most popular songs listed on the Billboard Hot 100 list from the end of the 1950s until the end of 2016. In total, about 6,000 works were examined. The algorithm assigned each emotional value, and then the average for the whole year.
As Kathleen Napier and Lior Shamir, who analyzed this data, observed, the most optimistic, joyful songs are the oldest ones. From that time on, anger, fear and sadness began to take over to reach the apogee in 2015. Only the middle of the 1970s and the beginning of the 1980s breaks from this trend.
As the researchers emphasize, it does not mean that the music itself has changed
Increasing aggression in the text layer does not mean growing aggression of the creators. This is a sign that the tastes of music consumers have changed
– says Lior Shamir. –
We just want to listen such things.
World richest people – Organization Oxfam report
World richest people – Humanitarian organization Oxfam report, prepared for the Economic Forum in Davos – 01.21.2015. Pointed out that the richest 1% will soon be together more wealth than the rest of the world. Today 80 richest has as much as 3.5 billion poor people living in the world, that is, half of humanity.
Solaris – Not only giants try their hand at new areas
Solaris – Not only giants try their hand at new areas for themselves. Polish Solaris, a manufacturer of buses and trolleybuses, took such a risk a few years ago, when decided to build a tram. For a company from Poznan buses are still the core product, but won tenders for trams growing. It started from Poznan, then appeared the German city–Jena, Braunschweig, Leipzig. At the end of 2015. Solaris trams will ride through Olsztyn, which exactly half a century restores this kind of communication.
Allow understand another person position
Allow understand another person position – In the first half of 2015. We found the mirror neurons so allow us to understand the position of another person that may even lead to a change of temperature of some parts of the body. Researchers at the University of Sussex in the UK, a group of 36 people showed three-minute films in which the actors put their hands in hot water, hot and ice, and the researchers measured the viewers heart rate and body temperature. When the subjects saw the film as a person shivering in the cold, dipping his hands in cold water, they felt chills. But it was not only a subjective impression. This change was detected thermometers. Temperature hand some test decreased by as much as 0.2 °C.
Dragon CRS-7 SpaceX
Dragon CRS-7 SpaceX – After the accident, 28 June 2015. At Cape Canaveral, the spacecraft Dragon CRS-7 company SpaceX. Which carried transport to the International Space Station (ISS). SpaceX issued a statement that it was suspending flights of its Falcon 9 launch vehicle accident caused the explosion of the rocket.
Ig Nobel Prize – Humorous parody
Ig Nobel Prize – Known as Anti Nobel Prize is a humorous parody of the Nobel Prize. It is obtained for extraordinary, unnecessary research or inventions. In 2015. Anti Nobel in the form of pots received the study of pain we feel after being bitten by insects. It turned out that the most vulnerable places are the lips, penis and nostril. In the field of physics Anti Nobel received an international team for the length of urinating in different mammals. According to experts, the size of the animal does not matter, almost all mammals empty their bladder in approx. 21 seconds.
Antarctica Station research expedition
Antarctica Station research expedition – At the end of 2015 went to Antarctica expedition consisting of six scientists from Masaryk University in Brno. The University conducts a research station in Antarctica for over 10 years. Part of the research is done even when the station is completely deserted. Energy from solar panels drives the recording weather equipment. Scientists started 30 different analyzes. They examine primarily climate change, the intensity of UV radiation and the ozone hole. The new expedition brought a prototype of a wind turbine generator created in the Czech Republic. If all goes according to plan, the current can be produced both strong and weak wind. The researchers also brought 200 kg of plaster on the walls, to test their resistance to weather conditions.
Gravity waves – Strongly shocked the scientists
Gravity waves – 14 September 2015 Recorded wave, which strongly shook the scientific community. The resulting “puckering up” space after the collision of two black holes, each having a weight of approx. 30 times greater than the sun. The existence of this phenomenon over 100 years ago predicted by Albert Einstein in the general theory of relativity. His theory was that the gravitational waves produced by massive accelerating objects. At the same time they can not be directly detected, because they are very small. Calculations showed that the change in gravitational issued by two orbiting black holes themselves would extend the line with a length of about a million kilometers distance smaller than the size of an atom.
Astronomers have for decades sought evidence of the existence of gravitational waves not only to confirm the theory of relativity, which began the modern era of research the origin and development of space, but also in order to test the hypothesis of cosmological inflation of the 80s.
