A brief history of internet from then till now

Today world is a globalized world. The use of Facebook, YouTube, and Google has really made our life very delightful but to take all the advantage of this thing we should first require an internet. Internet is a very broad way that connects all the PC computers, laptops, mobiles and other electronic gadgets. If we flashback to the past then we can observe a great history for the born of internet. In the past days the internet were not as much speed as it is being today.
          It was back in the year 1960 when first internet was used to connect the computer with only one computer of that time. It was not as known to everyone. At that time computers used to be very much huge and bulk size. ARPANET was the medium that used to connect with other computers. It stands for advanced research project agency. At the beginning it was used during the cold war to known the condition of the military soldiers and to give command. Robert.E Kahn and Vint cerf are said to be the inventor of internet. At the late of the 1960s four of the computers were able to connect with each other. In the same way the person were not able to communicate with each other. In the same time two computers of USA were managed to communicate. The computer from one state typed login but the computer from the Stanford received only the two words of the word login i.e L and O. In the year 1972 first time e-mail was introduced that changed the history of communication forever. In the same way it was in the year 1974 when first time the word internet was used. Besides this thing it was during the early 80s when local area network came into existence and connected the local area computer with each other. Officially at the late 80s internet was widely opened and became famous. Internet service provider expanded and gave the services of internet. In the early 90s world wide web www came into existence leading to the browsers like mosaic and netscape navivator. More than 90% of the internet user used netscape navigator as a browser. Finally different internet providers came into existence and served for the internet. PCI net and UU net were the internet service provider and finally it became very much famous among the people of the era. In the year 1997 Google was launched that acts as a search engine. By that time the computer was available on much compact and portable sized than it used to be in the past time.
Slowly and gradually the speed of internet was increased by different technologies. At first where the internet was carried on only by the LAN telephone network has been now advanced to fibre less medium. In the same way the concept of LIFI has been introduced.
        This is a brief history of the origin of the internet.

Why does earth spin on its axis, scientific explanation

We all know about rotation and revolution. Rotation causes day and night whereas revolution causes climate change. All the things in the universe rotates in their axis. We may not know the actual reason behind why do earth rotates. The revolution occurs due to the centripetal force tangent to the surface of the object. It revolves around the axis in the fixed path and by this simple moment climate change occurs.
       The main science behind the rotation of the earth is all our solar system has been formed by the masses of the clouds and if we observe it by sitting on the belt of our galaxy then we can see that whole of this particles and elements bombards with each other and due to this the earth spins on its axis. On the other hand some of the researchers also states that earth and all other planets are the product of the bigbang that occurs before billions of years ago. After bigbang all the planets began to spin very faster according to the theory of angular momentum conservation and conservation of energy. In simple definition they states that after bigbang they continue to move due to law of inertia. At the very beginning of the formation of earth it used to rotate very fast but slowly and gradually the gravity of the moon has dropped it down to the present spin level. The moon trues to stop the earth from moving but as it is very far from the earth it cannot do so. Unlikely it can surely will drop the spin level after billions of year.
   All the particles and molecules in the universe has different velocities and they move in different directions so the average velocities between them will become different. As a result they give rise to the angular momentum. The gravity between the particles will make the particles to condense and become contracted. When the particles are contracted there spin becomes faster. We can simply take an example of an ice skater whose spin will be double and treble when their arms are contracted towards they body but when their hands are out stretched then the spin will be slow. This moment of balancing of the spin is known as gyroscopic stabilization. Since the concept of the universe expansion appears to be real we can easily guess the slow spinning of the planets due to the contraction of galaxy obviously.
    This is the scientific explanation for the rotation or spinning of the earth around its axis.

Kundalini awakening: steps, symptoms

The word Kundalini has been derived from the Sanskrit word which has the meaning the power also regard as goddess durga. It is the cosmic energy that is present inside our body. It is regarded as a coiled serpent which is present at the base of the spine. It is remained in the passive form in the body. It can be invoke by various ways. Mainly to invoke it there is active way and another is passive way. Active way is the way in which the person invoke his kundalini by the active physical process i.e by different asans, by breathing control yoga, by mantra chanting and other various ways as the person has different limitations and the methods to invoke it is unlimited so it can be invoke by any ways.
For Kundalini awakening by yoga, it has been classified as three main types as kriya yoga, kundalini yoga and sahaja yoga. Before invoking kundalini we should know what it means.
         Awakening the kundalini means awakening the highest form of spiritual power inside us. When the energy from the muldhara is move up to the back of the spine and forwarding that energy to the top of the head and finally culminating that energy to the third eye. From this the whole kundalini awakes.
          For the invoke of this kundalini the practiser should follow one method to perform it. It may be either mantra chanting, yoga, deep meditation or any other. Practiser should strictly follow this practise everyday on the regular time basis. It should not be left even for one days. If break is taken then it may be difficult to invoke it. It should be practised on the guidance of master(guru). Daily practicing of it invokes kundalini energy. When the kundalini invokes different people have different sensations and feelings. The symptoms of kundalini awakening are:
1. It gives a sensation of electric current passing through all over the body. A positive vibe can be experienced.
2. In some persons the back pain has been observed.
3. Most common is the intense internal sound can be experienced that no one can hear.
4. The sudden change in the emotion of the person. Arising of different emotions.
5. In the later phase there may be the symptoms of mental problems, emotional problems and others.
         Hence this above are the things that are the symptoms and the process to invoke kundalini energy. This is the highest form of the spirituality by which a person invokes all his internal energy and self realize himself. The awakening time varies from person to person some may get it in 15 days, some may get it in 1 month some may get it in a year or so. By practising this kriya the person can get different or positive vibe.
       Although it has a good side but it may trouble if there may occur any defect or error during the practices. It doesn't go smoothly if it is not practiced under guidance and bring some health and mental problems which is known as kundalini syndrome medically.

Genetic engineering for eradication of malaria

       The most common and fatal disease that we suffer is the malaria. It is a very dangerous disease that can take the lives of the people. Malaria alone can take the thousands and millions of lives every year. It is a very dangerous disease. Actually this disease is caused by a special type of anopheles mosquito. This mosquito possess the plasmodium parasite which is present only on the special type of the female anopheles mosquito. When the infected person is bitten by the mosquito then the parasite is then transferred into the body of the person. This parasite attack to the liver of the person. It weakens the body system by taking all the RBC from the blood. It destroys all the RBC s of the body as a result the body antibodies are activated but they cant do anything because this parasite cover themselves by the membrane to protect from the antibodies. Due to this reason the person then suffers from the different body disorders like fever, cold and others. On the other hand the body immunity system continuously degrades as a result the person becomes weak and sick. He cannot do anything actively. If this parasite reaches to the brain then at that situation, the person finally goes to the coma. From there there is very little chance to come out and live a good life.
         Malaria is a very dangerous disease. This should be control. With the hope of this thing today our genetic engineering is very much advance and forward. By the help of genetic engineering we can easily manipulate and analyse the genes and can change them according to our desire. For this eradication process we have a technology called as the CRISPR technology. In this technology the artificial mosquitoes are prepared in the lab by changing the genomes of the mosquitoes. Their genome are made in such a way that they are plasmodium free. They do not allow the parasite to survive on their body so they can be termed as a malaria free. When they are crossed with the natural mosquitoes around our surroundings then in that case, half of the mosquitoes are malaria free while other half of the mosquitoes may be affected by the malaria. There is both the possibilities of but by the help of special genetic engineering we can easily develop the malaria free mosquitoes. Since the special genetic engineering is very advanced its risk has been said that the HIV, AIDS may be suffered from or by the mosquito vector. Since all the plasmodium parasites are the living microorganisms and a part of this nature. This may affect on our ecosystem.
        Hence this is the advanced technology helps in the eradication of the malaria from the world.

Science behind tratak meditation(focus)

         The word tratak has been derived from the Sanskrit word which means to see anything or to focus on a particular object or thing without a blink. There are different types of trataks. Some of the trataks are sun tratak. Specially this tratak is done to cure eye problems and normal vision. We need to focus on the rising sun a some minutes in the tratak and should wash our eye. Another tratak is the mirror trataks which is focusing on a mirror for a long period of time. It means for 5-8 minutes. On this tratak we need to focus on our right eye or we can also focus on the third eye chakra. We can get the siddhi or the accomplishment of this work or siddhi after 21 days or it depends on how you focus. Another tratak is the dot tratak or bindu tratak. This is the basic tratak that every one should know and understand before acquiring other trataks. From this tratak we can develop our concentration. If we focus on anything deeply and play that thing on our mind, then soon our view upon that thing will be changed. We may think in a different way. This are the primary thing of all the trataks sadhana. Another type of tratak is the candle tratak. For in a dark room a candle is lit up. This candle is then placed before the us and we need to pay our full attention upon that. All this tratak is done for only 21 days if we paid our full attention. This type of the tratak is also done before doing hypnosis. If someone is eagerly interested in doing the hypnosis then first of all he should learn this.
           After knowing about trataks, we should know about the science behind tratak. Our body produces electro magnetic field when we are charged up. It means when we focus on a particular thing or the object then all our body produces some kind of energy thus the energy produced by our body works under the control of mind. A person having 100% control over his mind can do anything and everything. He has a great and a good mind and a higher level of energy. This is the thing that some of the yogis and meditators levitate and perform the unexpected and unique things that we cant perform. Our body works like a magnet when we have a full or high potential. From this we can get a desired success and we can achieve our ambition easily. All we need to do is to activate our mind and body. Whole universe lies within us.
        Now after this lets talk about the benefits of this tratak sadhana. From this we can develop our concentration, attraction power, high level of confidence and also both our mind and body will be active and healthy. On behalf of this things tratak also helps us to develop a quick solution and to find the solution to any problems.
         Tratak is the useful tool for the focus to the people specially the students. We should perform it and should take a great benefits from it.

Why do selfie picture shows mirror image

The phenomenon of the light rays showing right appearance on left and left appearance on right is known as lateral inversion. Usually when we stand in front of a mirror then it shows lateral inversion. We cannot read the letters from our clothes. Also this is the reason that the word ambulance is written in the mirror reading form which when reflect from the mirror gives a correct word ambulance. In this topic we will discuss why do it occur and why do selfie pictures are laterally inversion.
       Today selfie has become a modern trend of taking the pictures in different postures. When taking selfie we might have observed that all the objects that are actually on left appeared all at right and vice versa. This doesn't occur while taking the pictures from the front camera. What might be the reason for this? Well the selfie camera act like a mirror. We might also have used it to look spots or any things like the mirror. It also shows the picture by the reflection and by same phenomena as mirror does so when we capture the picture the image it shows the mirror produce image due to which our brain gets confused on it and cannot detect how the appearance change. Due to the face symmetry also we may not feel the drastic change. We should consider the ray diagram for the reflection of light in the plane mirror. It also depends upon our psychology. For example when we look the mirror and wave our right hand then from our view the mirror side is also right but if another person stands side to the mirror and observe the image then from his view it is in the left side. The same thing happens when capturing the image from the selfie camera. It is like the same case as mirror as previously mentioned.
        Hence in this way the pictures from selfie acts as a mirror image. The phenomenon is called lateral inversion.

From where did god originate

We all know the theory of big bang. This big bang is supposed to be the first point for the origin of this universe. All the galaxies and the universe originate from this big bang. Slowly and slowly various type of mammals, amphibians and aves formed. Though there are different types of organism and their theory of evolution nothing could explain the the origin or the singularity of this evolution. Some of the theory states that the basic elements from the environment have created the living organism but it is not sure. How can the basic elements could be combine to form a living organism without external factors. Scientifically it is prove that there is some external power or energy which have run this universe. Spiritually we call it as god. No one knows if there is a god or not but people strongly believe on it.
         If the god is present then who might have created him. As we know nothing can be come out without a source. If we see in the Hindu mythology then it is not clear from where the god came from. It is strongly believed that before god also there was some of the external energy present. The source is very unknown. The whole thing is a paradox or illusion. We cannot find the singularity in the science. The world and the things around us is just a illusion. Nothing in this world is a reality. We all are made up of particles and each and every particles in this universe is made up of the electrons and due to the movement of this electron, its rotation. If we question it to the spiritual leaders then No one can give a mind set answer because they also don't know the answer. Today science has made a great drastic change a huge findings and the change but has never answered the singularity. If we observe this for a minute then we will find that all this birth, death is nothing except an illusion.
           All this things are a great paradox. The more deep we will go the more vast it is and finally observe that all this things can never be solved.
