Why is there a song stuck in my head?

 

earworm stuck songMost people enjoy listening to music and can name off several favorites when asked. But have you ever experienced an earworm? An earworm is when part of a song, usually catchy, gets stuck in a person’s mind and replays over and over.  You may also hear it referred to as a brainworm or stuck song syndrome. But why does it happen? Why is there a song stuck in my head?

Never-ending loop

When we listen to music the auditory cortex portion of the brain is actively involved. The more we listen to a song, the more familiar it becomes to the brain. The auditory cortex becomes good at filling in the rhythm of the song. This means that even when the song is no longer playing, your brain sometimes keeps singing along. why is there a song stuck in my head?You are forced to pay attention to the song and find yourself repeating it over and over. But the more you repeat the song the longer you perpetuate the cycle of involuntary musical imagery (INMI).

Bored Brain

Some researchers believe that having a song stuck in your head could also be a sign of an idling brain. The brain is trying to keep busy and so it latches on to a pattern of repetition. The songs most likely to get stuck have upbeat simple melodies with easy to remember repetitive lyrics. They also tend to be current trending songs or even advertisement jingles. To put it simply, the easier a song is to sing and the more memorable it is, the more likely it is to get stuck in your head.

It is estimated that 98% of people will have experienced an earworm at least once in their life. Interestingly, research shows that both men and women experience earworms at about the same rate although they usually last longer in women. Moreover, most earworms come from songs with lyrics – over 70%. Instrumental music tends not to cause earworms at anywhere near the same rate.

The British Journal of Psychology published a report in 2010 stating earworms usually occur in repeating loops of 15 to 30 seconds. They are also more likely to occur in people who listen to music more regularly or work with music. People who are tired and stressed will also have a higher occurrence rate. In fact, individuals with obsessive-compulsive tendencies report having earworms more often than those who don’t.

How to stop it

Research shows that engaging the brain in a different activity could help stop an earworm. The key is to engage working memory in mildly difficult activities. You can try doing puzzles, anagrams, math problems or even read a novel. Another option, for immediate relief, could be chewing gum.  song stuck in head remedy

The act of chewing gum can potentially stop an earworm by blocking the auditory cortex from repeating itself. The auditory cortex is stopped from producing and projecting auditory, especially musical, images. You could also try listening to the song in its entirety or playing a different song altogether. But some people report this can actually make it worse. So our advice is to try the gum.

 

 

 

 

Why is the ocean blue?

Water normally does not have a color. When we drink a glass of water, take a shower or bath or get caught in the rain, we don’t expect to be drenched in blue. And yet we are also used to the oceans and seas coming in a wide range of blues. Why is there such a difference? Exactly why is the ocean blue?why is the ocean blue

A lot of people might think that the oceans and seas are blue because they are reflecting the blue of the sky. This is not entirely accurate. It is actually sunlight, and the way it is dispersed, that causes the ocean to appear blue to our eyes.

light wavelengths

Light is made up of different colors with varying wavelengths. Red and orange light have longer wavelengths. When red light hits the water it is absorbed more strongly. Blue and violet lights, on the other hand, have shorter wavelengths. Blue is less absorbed by the water and therefore becomes more visible to our eyes as it is filtered out. This causes us to see the oceans and seas as mainly blue.

varying shades

The ocean and seas can take on a variety of shades of blue because of the way light hits and then bounces off other objects in the water, including sediment. For example, greener hues will result if more algae is present. If there has been a big storm, the oceans and seas can look a lot darker in color, even brown. stormy oceanThis is because sand and other sediment, including runoff from river, is stirred up and is closer to the surface.

Greater expanses of water can absorb more light. However, after 656 feet very little light gets through. Once a depth of 3,280 feet is reached no light penetrates. Deep water looks a lot darker because the more water light has to pass through the more it gets absorbed. Water closer to shore is usually lighter in color, even turquoise, because of the way light bounces off the floor of the ocean and other objects.

 

 

 

 

 

Why is there a leap year?

The next leap year is on February 29, 2020. why is there a leap year?Almost every 4 years we experience a leap year where one extra day is added to February, the shortest month of the year. So instead of 28 days in February, we get 29. But why is there a leap year?

Leap years are actually key in ensuring our calendar works properly.

making up for lost time

Most of the world now uses the Gregorian calendar, a solar calendar, which is based on the revolutions of the Earth around the sun. We know how long a year is from tracking the sun’s position and the seasons. The calendar has 365 days. But it actually takes the Earth about 365 days, 5 hours, 48 minutes and 45 second to revolve around the sun once. Without adding an extra day to February almost every 4 years, about 6 hours would be lost every year. That means it would only take 100 years for the calendar to become inaccurate by about 24 days.

Keep in mind that a leap year is not every 4 years. For every 400 years, 3 leap years need to be skipped. This is to make up for slight time discrepancies. So for example, 1700, 1800 and 1900 were not leap years. As you can see, these years are not evenly divisible by 400. In fact, any century year that is not evenly divisible by 400 can be a leap year.

The Gregorian calendar

Leap years first came into use more than 2000 years ago. The Roman general Julius Caesar adopted leap years into the Julian calendar which began in 45 BC. But at that time the only requirement for a year to become a leap year was for it to be divisible by four. This meant too many leap years occurred. This is a problem because of the effect on the seasons as the time adds up. By the 16th century, the vernal equinox had moved up from March 21 to March 11.

The Julian calendar was adjusted in 1528 by Pope Gregory XIII to rectify the time discrepancies.Gregorian Calendar Leap Year According to the Gregorian calendar, a leap year is identified as being evenly divided by 4 and also evenly divided by both 100 and 400. If a year can be evenly divided by 100 but not also evenly by 400, it is not a leap year.

why february?

You might be wondering how February became the default month for a leap year. The reason goes back to Julius Caesar. In the Julian Calendar, February had 30 days, July had 31 days and August only had 29. When Augustus became the new roman emperor he wanted August to have 31 days. To do this he added two extra days to August. One of those days came from February leaving it with 28 and not 29 days.

 

 

 

 

 

Why is Neptune blue?

Neptune is the eighth planet in our Solar System. It is now technically the last planet in our Solar System and the furthest from the sun. Pluto is no longer classed as a planet. Neptune was named for the Roman god of the sea and has a striking deep-blue color. But why is Neptune blue? Why is Neptune blue?

Neptune was only officially discovered in 1846 by mathematical prediction. This is because it is not visible without high-powered telescopes. In 1989 NASA’s Voyager 2 recorded real detailed observations of the planet, including its color. Neptune, along with Uranus, Jupiter and Saturn, is a gas giant planet. It is the densest giant planet.

Neptune is the third biggest planet in our Solar System. It has the fourth largest diameter and is roughly 17 times the mass of the Earth. It is also one of the coldest planets due to its distance from the sun.

chemical makeup

The reason for Neptune’s blue color is due to its atmosphere’s chemical makeup. Neptune’s atmosphere is mainly comprised of liquid ammonia, hydrogen, helium and methane. Methane is concentrated in the upper portion of Neptune’s atmosphere. The heavy methane clouds absorb the light from the sun. The red light wavelengths are absorbed more easily. The blue light wavelengths, which are shorter, are reflected back into space. Therefore we see the blue light and not the red, making Neptune appear a deep blue to us.

If you were to get closer to Neptune you would notice variations in its color. This is because of the way the clouds are formed above the surface. Neptune experiences a lot of storms with winds often surpassing 2.400 km/hour. Indeed, Neptune’s storms are the fastest in the Solar System. This contributes to the shifts in cloud cover.

Neptune vs. uranus

Uranus is also blue in color although more of a blue-green than Neptune’s deep blue. neptune blueThe fact that Uranus and Neptune differ in their shades of blue means that the chromophores found in their respective atmospheres are slightly different. Chromophores are chemicals that influence color. Scientists, however, have not yet determined which additional chromophore is influencing the color of Neptune’s atmosphere.

 

 

Why is gold valuable?

Gold has long been a highly desire and valued commodity. In fact it has been valued for more than 3000 years. Indeed, tradition has firmly linked it to the financial world as a currency and standard for currency. Let’s take a look at some of the reasons for why is gold valuable?

Gold, relatively rare, is somewhat difficult to find. It is also a time-consuming and expensive process to extract it in large amounts. This remains true today and that’s with the use of advanced machines. In the pre-industrial era people had to work with far more primitive means of extraction. The supply of gold is therefore entirely dependent on what is mined.

why is gold valuable?

Gold is also valued for its looks. It is the only metal with such a unique color. It has long been used for decorative ornaments. For example gold jewelry is desirable all over the world. The fact that it resists corrosion well also contributes to its value.

Gold is held by a lot of banks and investors. At the moment, one ounce of gold sells for more than $1000. It has long been a major part of the monetary systems of the world. This is true throughout thousands years of history. And yet gold does not produce earnings or dividends. Let’s look at the key reasons for why is gold valuable.

physical properties

As societies grew and developed, it became necessary to have a standardized form of currency for trade. The more traditional method of bartering goods for services and vice versa was no longer as useful. Over a long period of time gold became the most valued form of currency.

Gold’s physical properties have made it more valued over silver and copper in terms of worth. Although both silver and copper have their value. Silver is very useful for industrial uses. Copper exists in great quantities and has well-known electrical conductivity.

Gold, however, is highly durable. It cannot be destroyed by water because of its anticorrosion properties. Time also has little effect on it. We can see this from antique coins for example. It also only melts at a minimum temperature of 1945.4° F.

Another key physical property of gold is its malleability. Gold can be easily spread without cracking. It is also highly ductile which makes it easier to stretch without breaking. It’s color and shine also add to its appeal. It is arguably the most physically attractive of the 118 elements of the periodic table.gold valuable

For these reasons gold works well as money. Interestingly though the amount of gold found to date would only equate to 2 Olympic-sized swimming pools.

Tradition

Gold has had high purchasing power throughout history. In the time of Christ, one ounce of gold was enough for a Roman citizen to clothe himself in rich finery. Historians have established that in 400 BC, one ounce of gold could buy 350 loaves of bread.

Since 1933, when gold was taken off the gold standard, the value of gold has been on an upward trend. The fact that gold is now freely traded on the stock market has increased its worth and purchasing power.

But perhaps the most important role of gold is its ability to retain its value over time. Gold is ultimately a form of insurance against crisis and inflation.

long-term value

Gold is not required to be backed by banks, governments or brokerage firms. This is not the case when it comes to paper money which can drastically lose its value. This is also true for other paper assets, including stocks and bonds. Direct ownership of gold, however, means a guarantee for its worth. Keep in mind, however, that it’s worth can fluctuate.

form of currency

Gold, if you have it, is easily converted to cash. And its value is consistent. Banks and other financial institutions are unable to inflate the prices for gold. Moreover, it cannot be accurately counterfeited. These are all key financial traits that make gold valuable.

Gold is also easy to move around – it doesn’t take a lot of it to reach high value. If you split gold up, it’s value remains the same. This is not the same for diamonds which will generally decrease in value when split up.

long term investment

People have different opinions about keeping gold as an asset. A lot of financial industry workers would probably suggest investing in stocks. Other people point to history which shows gold has always retained its value. Fluctuations in the worth of gold, however, have happened. For example, in 2001 one ounce of gold was worth $260. It then peaked in September 2011 at almost $2000 for one ounce.

 

 

 

 

Why is protein good for you?

Protein is an essential part of body composition. Every cell in the human body utilizes protein in some way or another. For example, hair and nails are composed mostly of protein. Protein is also used to build and repair muscle tissue. Let’s look more in detail at the answers to the question why is protein good for you.

why is protein good for you?

Protein is a macronutrient. This means that it is important for the body to have fairly large quantities to work with. The same is true for fat and carbohydrates. Vitamins and minerals, on the other hand, are micronutrients. Micronutrients are needed in smaller amounts.

Protein is not stored by the body. This means that getting enough protein from our diets for the body to function properly is very important. Keep in mind, however, that you probably need less of it than you think you do.

Many people believe protein is responsible for building up muscles. This is not entirely true. Exercise and weight lifting exercises develop muscles. Protein, however, is a good source of energy to fuel the working of muscles.

How much protein?

The U.S. Department of Health recommends that male teenagers and adults consume a total of 7 ounces of protein per day. Young children, women and most older people are fine with 5 to 6 ounces of protein per day.

Many people point to the benefits of a high protein and low carbohydrate diet. This kind of diet can aid in weight loss. This is because a high protein, low-carb diet puts the metabolism in a state of ketosis. Normally, the body will use carbohydrates as its primary source of fuel. But when you cut down on carbs and eat more protein the body starts to burn its own fat. As the fat is broken down, ketones, small pieces of carbon, are released into the bloodstream. This can suppress appetite. It also increases the need to urinate, as the body is flushing out excess waste and fluids. This leads to less bloating and an overall reduction in water weight.

You should be careful, however, of very strict eating regimes. High protein low-carb diets may have short-term benefits, like faster weight loss but they can contribute to more long-term health problems. For example, you’ve probably heard of the Atkins diet. A lot of people lost weight on the high protein, low-carb diet where lean meat is the staple food. This is in part because of higher satiety levels. The more protein you eat, the less hungry you tend to feel. However, consuming meat every day can lead to major health issues, including cardiovascular disease. This is because animal products are high in saturated fat.

Not consuming enough fruits and vegetables when on a high protein low-carb diet is also not healthy. It’s important to eat plant products since this is where most of our vitamins and minerals come from.

healthy sources of protein

Eating a lot of processed meats like deli meats, hot dogs and sausages is not the best way to meet your protein needs. Healthier sources of animal protein include fish and chicken without the skin. You can also get great protein from plant foods.beans good protein Beans have the highest amount of protein found in plant foods. Black beans are especially good for you. They are also an excellent source of fiber. Nuts are another great option, though smaller quantities should be eaten because they can be high in fat. Whole grains also provide protein along with quinoa, which we eat like a grain.

not enough protein

If you are not getting enough protein in your diet you will become deficient in amino acids. The body uses protein every day to aid in growth and maintenance. It’s important for our skin and hair, the digestive system, hormonal balances and building immune system antibodies. Without adequate protein from your diet, you can experience lack of energy, fatigue, a sluggish immune system, low muscle mass, unstable blood sugar, moodiness, problems with memory and concentration and difficulties in losing or maintaining weight.
