  A lbert E instein's life was divided between politics and equation although he was a  great scientist of the World . His equation E=MC^2 brought a revolution in science . Despite his contribution to science, he was also involved in politics in order to maintain peace in the world .       Albert  Einstein was born on 14 March, 1879 in the town of Ulm in the Germany . Where he was at the age of one year , his parents migrated to Munich and started a small electro-chemical factory . His family was Jewish so he was brought up in the same faith but he was admitted to a Catholic school because there was no convenient Jewish School . He because interested in mathematics as he was influenced by his uncle . When Albert was 15, his father went bankrupt and closed the factory . Therefore, his economic condition became miserable . Then Albert looked for some technical institution that might train him for a scientific career . Eventually , after a second migratio...

  The Internet , one of the modern scientific discoveries , has changed the mode of human life . It is widely used for various purposes . It can simply be defined as a means of connecting a computer to any other computers anywhere in the world via dedicated routers and servers . When two computers are connected over the Internet , they ca n send and receive all kinds of information .          The Internet has provided us with multiple advantages . For instance, it is a huge source of information because we can easily find information above anything we want to know on the Internet . There are numerous websites . Among such websites, Google is widely used by most of the Internet users . Because the Internet can be used as a store of knowledge , it can be used  in teaching- learning program as well . Nowadays, we can find any e-books and journals which have made it economical for the readers to read directly the e-materials rather than the printed ones . ...

            G lobal W arming can be known as the increase in the average temperature of the earth's atmosphere due to different causes . According to scientists , its temperature is gradually increasing mainly because of human activities . Now this essay presents some of its causes , effects , and preventive measures and solutions .             Some of the major causes of global warming include ejection of unwanted gases or greenhouse gases due to human activities and volcanic eruptions . It has been estimated that average global surface temperature is likely to rise a further 1.1 to 6.4℃ during the 21st century as the result  of ejaculation of the gases . On Earth , the major greenhouse gases involve water vapor , carbon dioxide ( CO2 ) , ozone ( O 3 ) and nitrous oxide ( N 2O) . These gases are produced by burning solid wastes , fossil fuels , firewood and modern farming . Similarly , automobiles and factories are o...

Cryptocurrency For Beginners Imagine you're having conversation with your friends now at same point in this conversation someone's going to bring up crypto currencies now crypto currencies is something that everyone  wants to talk about no one really knows how they work so today I'm going to fix that . Crypto currency explained since man ,  world currency has been a very important part of our lives in caveman era they use the barter system now the barter system involves goods and services being exchange among each other so now we have a situation where two person is exchanging five apples and getting oranges in return now barter system fell out of use because it had some glaring flaws now these flaws include having peoples requirement coincide for example say you have five apples and your friend has five oranges now until and unless your friend has a requirement of apple you can't get oranges .               You will not be ready to make an e...

                Information technology has brought an unmatchable revolution in the field of information and communication ; 'Facebook' as its new innovation has appeared as a social network service and website launched in February , 2004 . Nowadays , many people are used to using Facebook and its has become their culture . It has both pros and cons .             Facebook users create profiles with photos , lists of personal interests , contact information , and other personal information ,too . They can communicate with their friends ,both real & virtual , through private or public messages . One of the most popular applications of the Facebook is the photos application where users can upload an unlimited number of photos . Privacy system can be set for individual albums by limiting users . Similarly, another feature of the photos application is the ability to 'tag' users in a photos .        ...

The Early Earth    The early Earth was like a blurred patch of scalding rock and chocking fumes . But the space , in which it was floating , was  cold so the surface of the EARTH also began to cold , So the surface of the Earth also began to cool down . Approximately 3,000 million years ago , the Earth was cool enough for land masses to form . Even so , our planet remained an alien world for the next several hundred million years . Rafts of solid rock drifted in the magma like dark ice floes .   Atmosphere ,Weather and Oceans -) Gases , carbon dioxide , nitrogen , gusted out from the cooling rock and enveloped the planet in a blistering atmosphere devoid of oxygen . As the Earth cooled, the steam began to condense into water , and the water ran down wherever the rocks were lower , which perhaps made the first oceans . These first oceans may have been short-lived . Space rubble  left over from the birth of the planets bombarded Earth continuously .   ...

  Physics Note ( Force ) 1) Clarify the statement , ''acceleration due to gravity of the earth is 9.8m/s^2 '' ? 👉 Acceleration due to gravity of earth is 9.8m/s^2 means that every freely falling object towards the earth  increase its velocity by 9.8m/s in every second i.e., at the rate of 9.8m/s per second . 2)The moon has no atmosphere , why ? 👉 Moon has no atmosphere because it has very small gravity so that it cannot hold the gases and therefore the gases escape into the space (with their escape velocity) . 3)Why is the weight of a body more at the pole than at the equator of the earth ? 👉 We know that the weight of a body (W) = m*g . For the the constant mass (m) of a body , the weight is directly proportional to acceleration due to gravity i.e., W α g. Since the value of "g" is more at the pole of the earth due to having smaller radius than  that of the equator , so, the weight of object is more at poles than at the equator of the earth . 4)A piece of ...

Origin      Like the other planets , the Earth is made up of molecules . These molecules were floating around in space , in a cloud of dust left over by the formation of our Sun . At first , just a few molecules clumped together .Then , the clumps began to crash into each other and stick together to make bigger clumps . Later , there were big crashes as pieces of metal and rock hundreds of miles across smashed into each other . There were huge clusters , one such cluster that formed about 150 million kilometers (93,205,678.8 miles ) from the Sun was planet Earth . The planet formation was largely completed in 10 - 20 million years . Orbit The Sun's gravity caught the Earth , as well as the other planets , and pulled them into an orbit around it . On one hand , the Earth's momentum was always trying to carry it away from the Sun in a straight line . On the other hand , the Sun's gravity kept pulling the Earth toward the Sun . As a result ,through centrifugal force , the Ea...

Biological time line of the Earth  Astronomical and geological evidence indicates that the earth was formed about 4.54 billion years ago . About 14 billion years ago ,there was a massive explosion called ''The Big Bang'', which released radiation ,particles and clouds of atoms . This Bag Bang is believed to have given birth to the Universe . Gravity condensed the atoms into galaxies where  stars appeared These Stars then began creating new types of atoms as they aged and exploded as supernovae . The Sun was formed around 4.5 billion years ago followed by the Earth around the same time.             Did you Know  ?   There is a lot of water in the Earth's atmosphere . In fact, there is enough water to cover the entire surface of the Earth with one inch of water ! Our planet is located  in the perfect place for our  need for water . If it was any closer or farther away from the Sun , all that water would either boil away or freeze...
