There is an even greater range of possibilities when it comes to composing melodies than writing sentences. That's because musical parameters aren't confined to the notes of whichever scale you're using — there's their rhythmic articulation, precise tuning, loudness, and timbre.
Mathematically speaking, it is possible that at one point we will run out of melodies to write and perform. The human ears are only capable of picking up a limited number of tones. Meaning, there is technically a limit to the number of different combinations you can place these sounds in to create songs.
Since all these combinations will sound very good, or even tuneful, the number shrinks further. We can imagine that the combination of few notes could give birth to some very mediocre noise. And so, a limit is imposed by the necessity of music sounding good or expressing emotion. The human ears just feel comfortable with those specific patterns and schemes.
We are so bound to those patterns that we can't be bothered to discover something different. In other words, we are just happy enough with the combinations of melodies, chord progressions, and meters we have explored so far. And we, as a society, tend to stick to those rules and patterns that define our taste, our history, and our culture.
Babies experience feelings like joy, sadness, anger, interest, and excitement. When we respond in ways that are sensitive to what the baby is telling us, he learns that his feelings matter, which builds his trust in us. We also nurture his curiosity which enhances his desire to keep on learning. Babies already notice differences in our facial expressions and tone of voice and figure out whether a new person or situation is safe. They pick up on and react to how we are feeling, such as — sad, angry or happy.
The baby can detect danger and needs us to make him feel safe. Danger can come in many forms for young children, from angry faces and reactions, rough handling, big changes in their daily routine, or being overloaded by too much stimulation.
They can also experience stress when they feel unsafe or frightening. Toxic stress — which is much more serious than short-lived, everyday stress is harmful to your baby's developing brain.
It would be a logical assumption that babies do dream, but it's hard to imagine the landscape of the baby's dream world since he doesn't have language or clear concepts of people and things.
Once the soil reaches about 64 F at a depth of 12-18 inches, the emergence of the cicadas is triggered. Male cicadas emerge first, followed by females a few days later. Once they leave the ground, they will shed their shells and develop wings, allowing them to fly around and locate fresh hardwood trees and shrubs.
The cicadas will then mate and that's when the singing begins. At the end of their life cycle, female cicadas will lay eggs inside tree branches. Newly hatched cicadas will then chew through the branch tips, causing them to fall off, carrying the young insects back down to the soil where they will spend the next 17 years.
There are about 3,000 cicada species on Earth, but only seven are periodical as they come out every 13 or 17 years. Some of the theories involve they choose a long time to appear to optimally avoid predators. Another one is that by using prime numbers, the periodical cicadas minimize overlap with other periodical cicadas, thus avoiding genetic hybridization and competition for resources.
Brood X, which has been underground in the Eastern U.S. since 2004, up until 2021. They will remain for four to six weeks, and then they'll die off, leaving behind the next generation. Brood X will next emerge in 2038.
The first reason is to make sure that the trunk is closed and no one is about to jump out of the trunk. The action also started as a way for officers to spook drivers before reaching their windows. The surprise of hearing a knock on their taillight might disrupt the process of hiding illegal drugs or weapons, increasing their likelihood of getting caught.
The second reason is touching the rear of the vehicle puts the officer's fingerprints on that car, showing that he or she was there with it. In case the driver decided to flee the scene, or if something happened to that officer, it ties both the vehicle and the officer together.
Before cameras were installed on the dashboards of most police cars, tapping the taillight was an inconspicuous way for officers to leave behind evidence of the encounter and help track down a missing member of the force even without video proof of a crime. Now, it's standard for all cops to have dash or body cams recording live video which has eliminated the original reason tail tapping was ever implemented.
Most eye floaters are caused by age-related changes that occur as the jelly-like substance called vitreous humor that helps to maintain the eye's round shape, becomes more liquid. Floaters are normally merely proteins of the vitreous gel that have clumped together. These stringy clusters of proteins block light and therefore cast a shadow on the retina.
Sometimes, small hemorrhages in the eye can cause floaters as red blood cells enter the vitreous. This can occur if the gel pulls on blood vessels located in the retina. Bleeding and inflammation in the eye, from retinal tears or blood vessel problems, tend to cause floaters in general. They can also be small specks of protein and other material that were trapped in our eyes as it was forming before birth.
Floaters can also be a sign of a more serious eye condition called retinal detachment. In this condition, the shrinking and pulling away of the vitreous causes the retina to detach. If we suddenly have more floaters than normal or are experiencing bursts of light across our field of vision called flashes, we should reach out to our eye care provider immediately.
