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.
CME – Coronal mass ejection – Eruptions on the Sun
CME – Coronal mass ejection – Every second the Sun emits around two million tons of particulate matter – or at least that’s usually the case. In the atmosphere, however, sometimes there are enormous eruptions from the corona (Coronal Mass Eruptions, CME). These types of hurricanes are among the most spectacular phenomena in our part universe . In the process, the Sun loses much more weight than usual. The speed of winds reaches even 10 million / h. CME is a cloud of gas built of electrically charged particles (physicists call it plasma gas). Plasma hurricanes can reach Earth and call the so-called geomagnetic storms that affect electronic devices, causing short circuits and equipment damage.
It is impossible to predict how dangerous it can be for satellites. The Internet and computer-controlled objects, such as nuclear power plants. The last really strong solar storm took place in the telegraph age, i.e. long before the appearance of PCs. Although astronomers are constantly observing the behavior of the Sun, they can anticipate it only slightly ahead of time. This means that in the future we will have at least 24 hours to disable all sensitive systems (even those in nuclear power plants) and secure computers. But geomagnetic storms are not the only problem facing us by the most important star …
Deja vu – This phenomenon denoting intense feeling that lived now the situation has already happened once. Deja visie (visited), deja vecu (longer lived), deja senti (already felt) – is another term for the feeling that the current situation has ever occurred. The experience is short, abrupt, with an aura of mystery. In the majority of cases occur in healthy individuals, at different intervals depending on the population. In ancient times such feelings associated with meta–psychosis – wandering souls. The current term began to use in 1873, when the first time used the words “deja vecu“, and three years later Emile Boirac used this phrase in the article “Correspondance“.
Space probe Deep Impact – NASA space probe
Space probe Deep Impact – NASA space probe named Deep Impact during the flight within 700 km of comet Hartley 2, was attacked pieces of ice about the size of a basketball. The researchers had never observed such a phenomenon. The reason for this situation was likely to influence the evaporation of solid carbon dioxide.
Spouses similarity – Assortative mating
Spouses similarity – Assortative mating – Evolutionary biologists and psychologists have called this phenomenon assortative mating.
“The choice of the man who is to us in a similar way, makes sense from an evolutionary point of view. Namely the physical resemblance is key to genetic similarity. This increases the likelihood that our genes are reliably transferred to the next generation “
– explains prof. Philippe Rushton, a psychologist at the University of Western Ontario – his work has shown that we choose mainly those features that have a higher heritability. To which include, for example, an increase in the circumference of the wrist, but not waist circumference.
Parasomnia – This is a phenomenon that accompanies sleep. Do not concern the length and quality of sleep. These are eg. Nightmares, night terror, sleep walking or wake up with confusion. An interesting type of parasomnia is a team of “exploding head” – in falling asleep there is a feeling that something exploded in or next to his head. It is very difficult to sleep after such an experience, but the doctors did not see any health risks stemming from this disorder.
Midnight sun – The phenomenon midnight sun, or the sun north, there is the polar north pole in summer (May to July). The sun is above the horizon for 186 days and beyond for only 179. The difference stems from the fact that the day we believe the situation where the horizon is even the smallest piece of the solar disk.
Right-handedness causes – Starts in the womb
Right-handedness causes – About 90% of people are right-handed and no one knows why. There are cultural aspects of this phenomenon. But it really all starts in the womb – 9 out of 10 embryos just sucks right thumb.
Near Death Experience
Near Death Experience – The experience of this type is referred to as NDE, or near-death experience (Near Death Experience). He invented them the most famous researcher of this phenomenon Raymond Moody. He based his research composed a list of common feelings of people who “returned from the dead.” Most of them experienced a feeling of “out of body“. They didn’t feel pain, were happy and calm.
