Harmony in music has nothing to do with mathematics 02.03.2024

According to new research presented by scientists from the University of Cambridge, Princeton and the Max Planck Institute for Empirical Aesthetics, the traditional connection of music with mathematics may be reconsidered. The tone and tuning of musical instruments have been found to be critical to the perception of harmony, contradicting the Pythagorean theory. As Pythagoras believed, harmony is a mathematically ordered system. Pythagoras came to this conclusion when he discovered that the basic musical intervals - octave, perfect fifth and perfect fourth - arise when the proportions of the lengths of the vibrating strings are 2:1, 3:2 and 4:3. Scientists have identified two key points where Pythagoras' theory, based on mathematical relationships, turned out to be inaccurate. Rather than deeming it important to strive for mathematical perfection in chords, listeners in normal listening conditions prefer slight deviations that add liveliness and appeal to the music. Doctor Peter ... >>

Conveying empathy through social interaction 27.02.2024

Scientists have made a discovery: empathy and compassion can spread through social interaction. That's according to a new study by an international team of scientists who conducted four separate experiments involving more than 50 volunteers to study changes in empathy. Participants' ratings showed that empathy levels, based on both self-reports and brain scans, changed after observing others' reactions. This suggests that caring for others can be contagious in society if enough people demonstrate it. “Depending on whether people were empathetic or not, empathy levels increased or decreased,” explains neuroscientist Griet Hein from the University of Würzburg in Germany. In each of the four experiments, empathy was measured after watching a video of a person being subjected to painful hand stimulation. Participants were then shown videos of other people reacting to the same videos, and again from ... >>

The value of pessimism in risk assessment 26.02.2024

In our time, the cult of optimism is considered the ideal. Phrases like “Why are you so pessimistic about life?” often sound like a reproach, and the term “pessimist” has acquired a negative meaning. However, an experiment conducted at the University of California at Berkeley involving more than 30 participants revealed interesting results: optimism often prevents people from making thoughtful decisions. Optimists often overestimate their capabilities, relying on luck and risking their finances and well-being. Similar findings are confirmed by researchers from the UK, noting that optimists' brains strongly filter information related to risks and mistakes. This area of ​​the brain, which is responsible for assessing risks, is less active in optimists, which leads them to underestimate possible risks and not pay attention to negative consequences. Unlike optimists, pessimists carefully assess risks and often have a backup plan in case of failure. Research has also shown that people perform better on tasks when they take action. ... >>
