The Storage capacity of human brain in gigabytes. This video discusses, what is the storage capacity of human brain? Is there a physical limit to the amount of information it can Store? Let me tell you, that the storage capacity of human brain is extremely large. So you don't have to worry about running out of space in your lifetime. There are about 1 billion neurons in the human brain. Each neuron forms about 1000 connections to other neurons, that results in more than a trillion connections. If there were no connections, we might have only a few gigabytes of storage space. Running out of space would be a problem if each neuron could only help store a single memory. But after combining, each neuron can help with many memories at a time. Because of this, the storage capacity of human brain increases exponentially. This storage of brain would be enough to hold nearly 3 million hours of TV shows!!!. In other words, we can say, if our brain worked like a digital video recorder in a television, then to completely use that storage you need to leave the TV running continuously for more than 300 years. That's huge amount of storage space.

Now let's talk about this amount of storage space in terms of gigabytes. It is close to around a million gigabytes which is equal to 2.5 petabytes. it is interesting to note that, certain memories take up more space as they involve more details while some information is not even worth remembering in the first place. Some memories are forgotten and hence they free up space. So you can put as much information as you want in your brain without worrying about its storage capacity, but remember to keep good memories not bad ones.

Here we will know amazing Facts about dreams. Like, why do we dream? What is the purpose of dreams? What goes on inside our brain while dreaming. What is sleep paralysis, Lucid Dreams and why some people have habit of walking during sleep (Night Walking). We will also see here, What researches and Studies are being conducted on dreams. you will get answers to all of these highly interesting questions related to dreams on the basis of Science. Friends, Our brain keeps collecting information related to everything we do throughout the day. Our mind keeps on doing this continuously, knowingly or unknowingly. And all this information is stored in our brain as memory.
Why Do We Dream Video
While sleeping, our unconscious mind keeps scanning all these stored memories so that we can use this information in a better way on the next day. During scanning, the information which the brain considers useful, is kept but it destroys the useless information or keeps it safe in any corner of the brain like a zipped folder in the computer.
But when these all processing are going on in our brain, we see different kinds of images, but our Conscious Mind cannot understand what is going on and keeps trying to make some sense of it according to itself. These random images that our conscious mind can not understand properly appear to us as dreams. So dreams help us to store important memories and get rid of unimportant memories. So Friends now you know why we see dreams and what is their purpose. Do you know, At bedtime, our mind is either in the REM stage or NON REM Stage. REM stands for Rapid Eye Movement and NON REM means Non Rapid Eye Movement. Many types of activities such as sleep walking, sleep paralysis, lucid dreaming etc. occur only in this REM stage. Many people would think that our mind is at rest while sleeping, but it is not so. Actually, when we sleep, our brain becomes even more active!!! When researchers studied the electrical activities of the brain of a sleeping person, they found that the electrical activities of the brain while sleeping were exactly the same as when awake. As you know, the muscles of our body stop moving when we are asleep and our body becomes very calm and motionless. Do you know why this happens? Actually, chemicals like histamine and serotonin stop being formed in our brain during the sleep. That is the reason, why we see different types of experiences like running, flying in the air, jumping etc. in our dreams, but no Movement happens in our body. So now you have understood how the chemicals coming out of the brain control the muscles of the body. After knowing this information, you can now easily understand why sleep walking and sleep paralysis occurs. Actually, when there is some imbalance in these brain chemicals while sleeping, a person may start moving his arms and legs and sometimes may fall down from the bed. But whenever the chemical imbalance is too much, then the person starts walking in his sleep. This is what we call sleep walking. Now we will understand what is sleep paralysis and why it happens?
Friends, has it ever happened to you that you have suddenly woken up from a deep sleep but are not able to move your body at all ? But this happens only for a while and after sometime you have complete control over your body. Friends, this is called sleep paralysis. Actually, this is because, when you wake up suddenly from sound sleep, then you know that you are awake but your mind thinks that you are still sleeping in the REM stage. That's why you are unable to move your body for some time. At this time you are in a condition known as Sleep Paralysis. So friends now you know why we see dreams, and how they are useful for us. Now whenever you see someone walking or shaking hands and feet in sleep, do not be afraid, as you now know that this all is just the imbalancing of brain chemicals. And don't be worried if you have sleep paralysis after waking up from deep sleep, as it's all due to short- term confusion of our brain.

Here you will learn, how many times it is possible to fold a piece of paper and what will happen on folding a Paper 103 times. We will check the fact that says, It is not possible fold a piece of paper in half, more than eight Times. After performing this experiment of folding a paper in half, I will show you with the help of mathematics, what will happen if we fold a piece of paper 103 Times!!! Do you know that if we fold a piece of paper 103 Times then its thickness would be more than the size of the observable universe!!! This is because of the exponential rise of the thickness of the paper, as after every fold thickness of the paper becomes double. Here I have the compared the thickness of the paper with daily life objects and different astronomical bodies after certain folds. I hope you will enjoy the video.

Do you know that, rocks can tell a lot about the history of a planet? Rocks are like Windows into the past of a planet. The Curiosity Rover by NASA has found evidences of water on the red planet - the Mars. Currently the Curiosity Rover is exploring an area within the 'Gale Crater' on the planet Mars. This area of the crater is known as the 'clay bearing unit'. In this crater area, the Curiosity Rover has found a rock that tells, Mars has not been dry as we see it now, it was a whole lot wetter in the past. This Rock has been nicknamed 'Strathdon'. This newly found rock has a unique wavy structures. According to NASA, this wavy personality is believed to be the evidence of flowing water, blowing wind or perhaps a combination of the two.
Water on Mars Found by Curiosity Rover of NASA Video
It has been found that the rock has a thick collection of flaky fragments. These flaky fragments are believed to be formed over a long stretch where clay was deposited and hardened before each new layer accumulated. Valerie Fox, a research scholar in Caltech said- "we are seeing an evolution in the ancient Lake environment, recorded in these rocks". "it wasn't just a static lake. It's helping us move from a simplistic view of Mars going from wet to dry. Instead of a linear process, the history of water was more complicated," Let me tell you, that there are also reports about the existence of giant water reservoirs on the Mars. These reservoirs are found over a kilometer beneath the surface. But the water found is not in the liquid form. It is in the form of ice layers. According to the scientists, the evidences found on the newly discovered rock indicate that the planet Mars had an ancient stream of water flowing over it in the past. Flowing water over a warmer Mars with a thicker atmosphere are sure signs of life on the planet. But according to the researchers, it would be too early to claim this. But there are good chances that the planet Mars would have been suitable for microbial life long ago. So dear friends, I hope you found the discoveries by the NASA's curiosity Rover about the possibility of life on our neighboring planet, the Mars, interesting. Sources and Credits 1
