"Dr John Powell, a Visiting Professor of Materials Science at the University of Nottingham said:  The sounds of music are not the same as noises. Your ears are there to make sure you stay alive: they're a warning system, designed to analyse sounds for danger. But we can quickly recognise that a musical instrument is unlikely to be lethal. When you hear music, your ear drum moves in and out in a regular, repeated way, many times a second. We recognise that it's not dangerous, so we can focus on the harmonies and tunes – and enjoy them." Moreover, we don't enjoy bad music, we enjoy the music that has a repetitive rhythm in it, as we listen to it we wait for that rhythm to arrive again, and just as it does we have feelings of accomplishment. Depending upon our culture and habits we like different types of music. It's also manifestation of human urge of pleasure, that sometimes we find in paintings, art, and religion. A soothing or good music gives us feelin

The days have long passed when humans used to protect their borders from other intruders and hunters. This was done to preserve the limited supply of food available and to let animals living in that area breed and multiply in numbers. Then we became more advanced and learned to grow food, started doing animal farming and gradually opened up our borders for others. But still borders were not opened for everyone. There were restrictions. Only those with skills to help us grow our food better were allowed and then those who already had equal or more amount of food and farmed animals in their own territories, the later group was welcomed because they could help us in the times of need. This behavior is still governing our minds. If we look at visa policies of countries, no nation gives visa free entry to the people of the country which is poorer than themselves. Now a days either you have to be exceptionally skilled or a person from an equally or more developed nation to be able to travel

Rain fascinates women more than men. Because historically it hints them that there'll be more food to eat and feed her family as men used to hunt but females used to pick fruits n edible roots, they did so for millions of years and now this instinct has got imprinted on them. Rain gives them sense of independence and it's similar when a modern female gets salary from her job. Females also call rain romantic because females realize that they can now have more babies whom they can feed in coming years, as now they have food security. In African savanna a single rain usually supports plants for more than a year. European females doesn't enjoy rain as much as Asian or African females do. Modern analysis of DNA of modern humans have revealed that Europeans have 3 to 4% of Neanderthal DNA which is completely absent in Asians and Africans, of course in those who didn't interbred with European ever in the past. Unlike Homosapien females, Neanderthal females were hunters like th

When The Arab Muslims invented Algebra they called the unknown factor in an equation as "الشیئ" meaning "a thing". When Spanish translated the Algebra to their language they didn't have the word to represent the sound for "ش" hence they borrowed the Greek alternative for it called "kai" written as "ϗ". Later when Algebra was translated to English they took the unknown factor  "ϗ" as "x". And that's how we got the unknown "x".
