What is dropbox its working with benefits

Are you fed of storing your important documents and files in memory cards, pendrive or any other additional storage materials. If so then today I will be showing you guys about a very useful and reliable source of storing files and documents and also helps to share it with our friends circles, families and relatives. Now lets directly discuss about that service.
      Dropbox is a good and reliable service that helps in the storage of files and folders and share it with the relatives and friends. The storage is also available as in the form of cloud storage. The dropbox service is provided by American dropbox, inc. It was first time founded by Drew Houston and Alas ferdowsi who were the  former student of MIT. It was launched in the year 2007. Since then it has been providing its hosting service around the world. At first it was launched on a small service slowly and gradually it became bigger and began to expand.
       Basically it works on the principle as first it creates a folder in the synthesized dropbox hosting site and then it connects that server for the folder to all the computers who sign up to their hosting site. In the basic package the users can store up to 2 GB of data and in the premium basis they are given up to 1 tera byte of storage. It offers its service in all operating systems including windows, android, Mac, iOS and many others. According to a census of 2016 it has more than 500 million users who are using this service. Due to the open facility and some debugs it has faced many errors during the initial stage in addition of security preaching and leakage of the privacy. By now all the problem has been fixed and it is now it is one of the important hosting services in the world.
       It is very easy to use its services simply one have to go to its official website and sign up with the email id and name. After then a folder is need to be create and in that folder all the basic things are need to be uploaded and finally a basic or premium package is need to be selected according to our choice and we can easily upload and download any files by simply log in. It is one of the most valuated start up company in all over USA with an estimated valuation of 10 billion dollar.
        Hence this are the benefits and the working principles of the dropbox.

Ferro liquid clock and the working behind it

Ferro liquid watch better known to be ferrolic watch is a boon of science and technology. It is a scientific clock available in the different forms and it is at its top of a beautiful creation of art by the design of science. A thin layer of ferro liquid is placed behind a glass panel and behind that liquid are the numerous magnets that make the liquid to take digital numbers form. It looks very advanced but the principle of it is very simple. Before entering this lets first discuss about the ferro fluid.
          This ferro fluid was first time introduced by Steve papell who was then NASA researcher. This is the fluid of the rocket fuel and he first time noticed that the fluid was easily drawn out in the presence of magnetic field. Since then it get this name of ferro fluid. This ferro fluid is made up of very tiny ferro magnetic and ferric magnetic substances that are of the nano scale and that are present in the water as the freely suspended residue. It is a very big clumps available in the first but after that different filtration is undergone to make it a very small nano size particle. All the intermolecular force of attraction between the molecules of the magnet to attract opposite charge cannot overcome vander wall force of attraction as a result they need another magnetic field for the free moment of the molecules.
     In other sense the ferro liquid used in the clock us always perpetual since it is operated by the magnetic field to the ferro liquid. On behalf of this thing today this clock is gaining more and more popularity by the time. Since it is a good fusion of science and art thus it is very attractive and eye-catching. This clock needs no any other source of energy to move but simply a magnetic field. It can be damaged if it is brought near to a high magnetic field source.
      Due to this high popularity and a unique concept the price of this watch is slight high. It is available in $8500 around the USA, Russia, and many other countries. The clock tick tock of the digital number changes its form in each seconds. It has very less disadvantages due to this it is gaining popularity very much. The liquid is expensive due to this reason the clock is also expensive. This is the working of the ferrolic clock and the special liquid behind its construction.

Why alien megastructure star is dimming

It was in the year 2015 summer, when the researchers found most fluctuation of light from the apart stars. It is about 1400 light years to where this incident is supposed to happen. Many of the researchers have thought of it as a alien made megastructure in front of the parent star. This blocks too much light as a reason only 25% of the light is observed on the earth. It is observed by the Kepler telescope. Before 2015 it was not a topic of major issue but after its observation this megastructure is supposed to have been made by the aliens. The parent star name is KIC 8462852, whose light is being blocked by the megastructure. On behalf of all this things its concept first came from the view that there might happen some mega or large event that captured all the energy of the stars giving rise to the megastructure. However since the star is nit emitting the infrared radiation so cant be said as a perfect star.
        According to the different theory the parent star is being surrounded by lots of the huge solar panel so as to absorb a huge amount of light and finally converting that energy to the usable form for the betterment of civilization. This structures are constructed in a perfect geometrical manner and this is known to be alien megastructure as it is supposed to be  constructed by alien. The researchers are not able to detect what is the actual thing behind the dimming of the star but have shown a graph in which the dimming rate is very high. Since this star is very far from the earth we need thousands of years to go to that place and research.
      However more details about this star is not available so we cannot count the actual reason behind this discovery. Whatever be the reason but now it suggests that we might not be the one of the living around this universe.

Kepler telescope and k2 mission of NASA

Our universe is so large that we cannot imagine about it. In this huge universe there are infinite heavenly bodies that we cannot imagine. Also according to the researchers and scientists, they claimed to have communicate aliens or have received the SOS signal from them. Though they say but none knows till today. It is one of the most controversial subject but most of the researchers believed that there are the presence of some extra- terrestrial livings in other planets. With this hope of finding other planets and the presence of living organisms in the other planet. NASA on the year 7th march 2009 launched the Kepler telescope and it is launched far distances from the earth. It is launched at the special place to observe the 5 phases of the earth. It helps in the detection of planets that it observes when the planet revolves around the bigger heavenly planet like the earth does it to the sun.
       This mission of NASA to discover to discover far unknown distances and their special mission to research it for the future settlement of the human species is known as k2 mission of NASA. On behalf of all this thing it has discovered many of the planets that is similar to earth as well as which are hot as compared to the sun, some are very big as compared to the earth. It is launched at the heliocentric orbit of the earth space. The Kepler telescope is name after the famous astronomer Johannes Kepler.
     The latterly discovered planet was Kepler-22b. This planet was much more similar to the earth and now the researchers are searching for the possibility of life in this planet  but for this more research is required. It is about 600 light years away from us. It completes its one turn revolution around its orbit in about 300 days. It is said that the planet has water and some of the aquatics life may be present in that place. After this planet was discovered Kepler also found another planet which they name as KOI-2626 which ground is similar to the earth. This planet too has a source of water but it has too high temperature. The another planet Kepler 62f, this planet help us one of the most famous planet. This planet has all things that are possible for the survival. This planet is said to have the existence of aliens. This planet is under observation and is hope that this planet may be source for the future survival of the humans and livings of the earth.

Kuiper belt: Objects and some facts

It was back in the past year when Pluto was discarded from the solar system. The reason was that the researchers and astronomers found many of the same looking objects around it. It was very difficult to include billions of them into the solar system and was easy to discard Pluto from it. The icy objects beyond the Neptune planet was previously coined as Pluto but the whole belt of that objects are now collectively called as Kuiper object. The whole of this object forms a belt and thus known as kuiper belt. This belt are known to be the orbit of Neptune.
Since this term and the concept was first given by the dutch astronomer Gerard kuiper thus is then named after him. It is extended somewhat like 45 degree across the sky. The kuiper belt objects are mostly composed of volatile substances and gases. Some of this gases include methane, ammonia and water. It is regarded as the basis series for the three dwarf planets they are Pluto, makemake, haumea.
        On behalf of this thing it was first proved due to the visitation of far comets to the solar system but though it was not confirmed because our universe is infinite and they may come from any part of the universe. This was find out finally in the year 1992 when researchers observed a slow moving object that is heading further far away and thus it was concluded to be Kuiper belt. However all the theory of Kuiper didn't go well right about it. The scientist told many of the theories about the kuiper they have predicted that there are more than one hundred thousand objects on the belt of kuiper and all of them are of very heavy size but our bad fortune, we are only able to find out nearly one thousand kuiper objects by far. In the same manner another thing that the scientist predicted was this objects wouldn't last long and they got succeed in it. They just fuse and collide with each other giving a huge bulk of dust and by this collision they would have no more existence in the future. It is located at the 30-40 amu from the earth and sun.
        It contains many comets and contains previous icy objects which were formed at the time of the solar system so could be used to study about the estimated age of the solar system and that of the planets.

Unknown man in the dream- science behind it

We all dream on our sleep. Its natural and we see so many different things on our dream. Actually we dream the things that are actually suppressing onto our deep mind. According to a renown psychiatrist we dream the things which we cant express on our real life. It may be due to our social taboos, fear and many other both external and internal things. On behalf of talking this things what if a same person appears on about 2000 people dreams most of the time.
        This event happened in the year 2006 when a psychiatrist's friend visited him and told him that a man of middle age was been shown him everyday. At first he didn't matter a lot but when his friend continuously began to see that man in his dream than it became an issue. By the help of his friend psychiatrist drew a picture of that man that both of them had never seen in their real lives. They forgot to take out the picture from the desk. After some time another patient came and he was shocked to see that picture of that man and told him that he had previously seen that man into his dream. This incident became more and more famous and finally the psychiatrist sent that picture to all his psychiatrist friends. By that time more than 2000 people were there who claimed to have seen that man in their dream. Some of them shared that, that man helped them out whereas some of them told that that man had punished or assault them. This was the serious issue by that time finally this was transferred to the higher level of the state. From there this picture of the man got viral in the internet.
          The science behind the picture of the man is that the man is all the mixture of our emotions. This is the theory of the collective emotion representation. Also according to another theory it states that the man shows different face patterns when different face patterns were fused. This symbolizes that our mind is all of the emotions. In the same way some of the theory also suggests that the person belongs to a secret group of the website and from there he is controlling the mind of the person. Today millions of the person have stated that they have seen that man in the dream. In real life none knows if the person really exists or if its only in the dream.
       This is the science behind the man in the dream.

Ebola symptoms detail explain 2017

Ebola also known by its scientific name EVOV is a very serious disease. This disease was first discovered in the year 1976 in the Sudan region and Congo region according to the census by WHO. This disease was latterly discovered or took its form in the year 2014 from west Africa then by took a serious form in most of the american and African countries. It is a very dangerous disease and about 950 people have lost their lives from this disease. This disease is caused by a virus from the family filoviridae and that have caused many severe disease but this disease is too serious. About 90% of the people under treatment has been died by the effect of the virus. In the very first beginning this disease was found in a person from the west Africa. It is said that this disease is transferred by the animals to the humans and non primitive animals like monkey, gorilla, chimpanzee. The first person has this disease due to attack of bat. Then it is transfer from one person to another person in a very fast and short period of time.
      This disease is simply transferred by the mucus or body fluid of the infected person if one has some injuries, broken skin or mucous membrane then it is transferred to another person through blood stream.  The incubation period of this disease ranges from 2 to 21 days by the time the virus enters into the body of the person. The symptoms of Ebola are as follows:
1.  The major symptom of this disease is the hemorrhagic fever that means the infected person will bleed excessively both inward and outward.
2. The infected person may have some of the discomfort they may feel sick along with sore throat and headache accompanied by muscle pain and fatigueness.
       This symptoms occur when the virus attacks the T- lymphocytes of the person.
      Now after this symptoms lets talk about its preventive measures since it is a viral disease so no medicine has been developed against it. Some of the preventive measures of this disease are as follows.
1. Since this disease is communicable so one should avoid to visiting that outbreak territories.
2. The remains and the funeral ceremonies should not be done of Ebola infected person.
3. Hands should be frequently washed.
4. Eating of raw meat should be avoided. The meat should be properly cooked.
5. We should be aware of wild animals and bats.
           This are of the details about Ebola it's symptoms and its preventive measures.
