Supercomputers Are Said To Be Those Computers Which Are At The Forefront Of Computing Power And Some Other Matters At The Present Time Equipped With State
Several microprocessors work together to quickly solve any complex problem. The supercomputer is the fastest, most efficient and has the highest memory capacity among the computers currently available. According to the modern definition,those computers, which can operate with a capacity of 500 megaflops, are called supercomputers. Supercomputers can do a billion calculations in a second. Its speed is measured by mega flop.
The first supercomputer is Illiac 4, which started working in 1975. It was developed by Daniel Slotnik. It alone could handle 64 computers at a time. Its main memory could hold 8 million words and it could perform arithmetic operations in the ways of 8, 32, 64 bytes. Its working capacity was 300 million calculation actions per second, that means it could solve 300 million problems of addition, subtraction, multiplication, division in the time that we could barely count up to 8.

Your Brain Uses 20% Of The Oxygen And Blood In Your Body
Your brain needs a constant supply of oxygen. As little as five minutes without oxygen can cause some brain cells to die, leading to severe brain damage. Also, the harder you think, the more oxygen and fuel your brain will use from your blood up to 50%.
Every minute, 750-1,000 milliliters of blood flows through the brain. This is enough to fill a bottle of wine or liter bottle of soda.

Dreams Are Believed To Be A Combination Of Imagination Physiological Factors And Neurological Factors
The limbic system in the mid-brain deals with emotions in both waking and dreaming and includes the amygdala, which is mostly associated with fear and is especially active during dreams. Dreams are proof that your brain is working even when you are sleeping. The average human has about 4-7 dreams per night.

Is There Such A Thing As Being Left
Well, your brain definitely has a left side and a right side . Each hemisphere controls certain functions and movement on the opposite side of your body.
Beyond that, the left brain is more verbal. Its analytical and orderly. It takes in the small details, and then puts them together to understand the whole picture. The left brain handles reading, writing, and calculations. Some call it the logical side of the brain.
The right brain is more visual and deals in images more than words. It processes information in an intuitive and simultaneous manner. It takes in the big picture, and then looks at the details. Some say its the creative, artsy side of the brain.
Theres a popular theory that people can be divided into left-brained or right-brained personalities based on one side being dominant. Left-brained people are said to be more logical, and right-brained people are said to be more creative.
After a two-year analysis , a team of neuroscientists found no evidence to prove this theory. Brain scans showed that humans dont favor one hemisphere over the other. Its not likely that the network on one side of your brain is substantially stronger than the opposite side.
As with most things relating to the human brain, its complicated. While each hemisphere has its strengths, they dont work in isolation. Both sides contribute something to logical and creative thinking.

Do We Use 100% Of Our Brain
Do you know everyday we use 100% of our brain. Yes, opposed to the famous myth that no one uses 100% of their brain, the reality is that we all use it completely. Every part of our brain is associated with some part of our body, and while we are still alive, we use all the parts. So our brain is used to its full mass. Yes, one thing we can say is that we do not use the full potential of our brain. The human brain has infinite potential.
For instance, there is nothing in the world you cannot understand or learn but some just give up thinking that they cannot do it. The reality is every brain is equally strong to learn and understand. You need to tap into that untouched potential of your brain, give some more time to that work, and VOILA, its done.
Brain capacity is unlimited. The more you use it, the sharper it becomes.
Keep The Brain Active
The more a person uses their brain, the better their mental functions become. For this reason, brain training exercises are a good way to maintain overall brain health.
A recent study conducted over 10 years found that people who used brain training exercises reduced the risk of dementia by 29 percent.
The most effective training focused on increasing the brains speed and ability to process complex information quickly.
There are a number of other popular myths about the brain. These are discussed and dispelled below.

Alcohol And The Brain
Long-term alcoholism can lead to a number of health problems, including brain damage.
It is not, however, as simple as saying that drinking alcohol kills brain cells this is a myth. The reasons for this are complicated.
If a woman drinks too much alcohol while pregnant, it can affect the brain development of the fetus, and even cause fetal alcohol syndrome.
The brains of babies with this condition may be smaller and often contain fewer brain cells. This may lead to difficulties with learning and behavior.

The new Luc Besson movie Lucy, starring Scarlett Johansson, opens tomorrow in theaters countrywide. Its based on the immortal myth that we use only 10 percent of our brains. Johanssons character is implanted with drugs that allow her to access 100 percent of her brain capacity. She subsequently gains the ability to learn Chinese in an instant, beat up bad guys, and throw cars with her mind . Morgan Freeman plays neuroscientist Professor Norman, whos built his career around the 10 percent claim. It is estimated most human beings use only 10 percent of the brains capacity, he says, Imagine if we could access 100 percent.
As it happens, Ive written a book all about brain myths . I thought Id use what I learned to give you a 60-second explainer on the 10 percent myth.
Great Myths of the Brain, by Christian Jarrett, was published in 2014. .
No, the 2011 movie Limitless, starring Bradley Cooper was based on the same idea, except the precise figure was placed at 20 percent. Coopers character takes a pill that lets him access the full 100 percent. Both the 1991 film Defending Your Life and Flight of the Navigator include claims that most of us use a fraction of our brains. The myth is also invoked in the TV series Heroes, to explain why some people have special powers.

Effects Of Technology Advancement On The Brain
Technology has been a boon for our generation however in todays world, technology affects our brain negatively. In many cases, it has been observed that internet/gaming addiction leads to shrinkage of tissue volume in the brain. Apart from this, it leads to anxiety, depression and sometimes to even suicidal thoughts thus disturbing our mental equilibrium. It is even recommended that we should stop relying on machines for basic functions such as calculators or GPS navigators. This way we do not allow our brains to exercise which in turn inhibits in expanding our brains beyond its limits.
How Much Of The Brain Do Humans Actually Use
When talking about human organs it doesnt get much more complex then the brain. The brain is a mechanism humans use to read, write, process information, express emotions, and retaining memories. Theres no question that the brain is an extremely powerful and intricate organ but how much of the brain do we actually use?
Im sure at one point or another everyone has heard the myth that humans only have access and control of up to 10 percent of their brains. Keeping this in mind I always wondered what would happen if a Human gained access to the other 90 percent of their brain. Would they be able to read minds? Could they suddenly have the power of telekinesis, or would their IQ break world records? Unfortunately this myth couldnt more wrong. So whose to blame for this 10 percent myth that got so many average peoples hopes up. William James was an american psychologist who published a book called the The Energies Of Men. In this book he stated without any scientific proof that humans are only tapping into a very small part of the brains mental and physical resources. This claim is what eventually started the 10 percent myth.
Dr. Barry Gordon a professor of neurology at the School of Medicine and professor of cognitive science at the Krieger School of Arts and Sciences had this to say.

Short Term Memory Lasts About 20
This has to do with your brains capacity for holding small amounts of information in the active mind. The brain keeps this information in an available state for easy access, but only does so for about a minute and a half. Most people hold memory for numbers around 7 seconds, and memory for letters around 9 seconds. In addition, the brain can store up to 7 digits in its working memory. That is why the telephone numbers in the United States are 7 digits long. Learn more about Memory Disorders.

How Much Of Our Brain Capacity Do We Use
The human brain consists of about one billion neurons. Yet neurons combine so that each one helps with many memories at a time, exponentially increasing the brains memory storage capacity to something closer to around 2.5 petabytes .
Lets not get too technical about it and boredom strike you!
There are few myths about how much of capacity we use, one among those being that an average human being uses 10 percent of it and even in the movie Lucy Scarlett Johansson was portrayed to be having to use 10 percent of her brain at first.
Recent studies and 65 percent of the Americans let us know that the highly successful people tend to use their brains at 6 percent and Albert Einstein used 11 percent of his brain capacity and became the greatest scientist mankind had ever witnessed.

The Visual Areas Of The Brain Are In The Back
The part of your brain responsible for vision, the occipital lobe, is located in the back. This is why if you get banged in the back of your head, you will see stars. The left side of your brain controls the vision on your right side, and vise versa. Your brain also processes sound on the opposite sides of the head.
Debunking The 10 Percent Myth
Neuroscientists point out a number of reasons why the 10% myth is false:
- Brain imaging scans clearly show that almost all regions of the brain are active during even fairly routine tasks such as talking, walking, and listening to music.
- If the 10% myth were true, people who suffer brain damage as the result of an accident or stroke would probably not notice any real effect. In reality, there isn’t a single area of the brain that can be damaged without resulting in some sort of consequence.
- We would not have evolved such large brains if we were only using a tiny portion of them.
- The brain uses approximately 20% of the body’s energy. It would make little evolutionary sense to have such a large portion of our energy resources utilized by such a tiny amount of the brain.
- Brain mapping research has yet to find any region of the brain that does not serve a function. “Numerous types of brain imaging studies show that no area of the brain is completely silent or inactive,” wrote Dr. Rachel C. Vreeman and Dr. Aaron E. Carroll in a study of medical myths. “Detailed probing of the brain has failed to identify the ‘non-functioning’ 90 percent.”
Unfortunately, the 10% myth remains both popular and persistent. It has been repeated in popular culture in everything from advertisements to television programs to Hollywood blockbusters such as the 2014 film Lucy starring Scarlett Johansson and Morgan Freeman.

They Looked At Mris Just To Be Sure
Unfortunately, just because you truly use more than 10 percent of your brain, does not mean you’re going to begin developing telekinesis.
Scientists have measured how much brainpower people use when doing certain activities. Healthline noted researchers look at brain activity through a magnetic resonance imaging . They ask people inside an MRI to look at photos or do certain exercises, and they study which parts of the brain light up when performing those functions. There’s even an episode of MythBusters where they tested the 10 percent myth. The MythBusters team asked people to accomplish complicated mental tasks word associations, memory drills, calculations and found that people use at least 35 percent of their brains to perform those activities.
What scientists can generally agree on is that we don’t yet fully understand the full brain. Scientific American said researchers continue to study the different parts of the brain to figure out the function of each. Generally, we know about neurons, but what about the glial cells that support neurons? What are their function? Nor do scientists know where consciousness comes from. We know that people use far more than 10 percent of their full brain capacity, but scientists are also still trying to understand more about how the brain works and what its full potential can be. In the meantime sorry. You really can’t make yourself read minds.
Where Does The 10 Percent Myth Come From
Its not clear how this myth began, but there are several possible sources.
In an article published in a 1907 edition of the journal Science, psychologist and author William James argued that humans only use part of their mental resources. However, he did not specify a percentage.
The figure was referenced in Dale Carnegies 1936 book How to Win Friends and Influence People. The myth was described as something the authors college professor used to say.
There is also a belief among scientists that neurons make up around 10 percent of the brains cells. This may have contributed to the 10 percent myth.
The myth has been repeated in articles, TV programs, and films, which helps to explain why it is so widely believed.
Like any other organ, the brain is affected by a persons lifestyle, diet, and the amount that they exercise.
To improve the health and function of the brain, a person can do the following things.

Your Brain Is Mostly Fat
Consisting of minimum 60% fat, your brain is the fattiest organ in your body. This is why healthy fats, such as omega-3s and omega-6s, are vital for brain and overall body health. Healthy fat helps stabilize the cell walls in the brain. It can also reduce inflammation and helps the immune system function properly.
