2021-10-07 18:03:37 WHY does black absorb more heat than other colors?

According to the physical laws, the color of any object is a spectrum of reflected light. Any object absorbs all waves, but reflects only those of a certain wavelength.

Only black reflects nothing. It represents the absence of light. Thus, all the light and thermal energy that enters it, remains inside of it. Открыть/Комментировать

The thing is that a domestic cat's claws are curved on the inside. That enables it to climb up the trunk of a tree deftly. But the claws cannot support the animal as it descends.

Scientists haven't given an absolute answer to this question yet. But we do know that the reaction to rhythmic music is innate. Even young children, never seen a dance, trying to move to the rhythm.

According to the hypothesis of the Austrian musicologist Richard Wallaschek, music itself was born as a means of coordinating rhythmic movements, especially the movements of a group of people.

Also, there is evidence that music and coordinated movements stimulate the pleasure centers in the brain. Открыть/Комментировать

2021-10-01 20:51:43 WHY does warm milk act as a sleeping pill?

One glass of milk (250 ml) closes the body's need for tryptophan by 50%. The body converts tryptophan (an amino acid) into serotonin, which helps control mood and sleep.

Besides, milk serves as an excellent source of calcium, which regulates the production of melatonin.

If you can't fall asleep, drink a glass of milk with a teaspoon of honey. It's a great way to shorten your falling asleep time and improve the quality of your sleep. Открыть/Комментировать
