This is different from the natural satellites, or moons, that orbit planets, dwarf planets and even asteroids. Artificial satellites are used to study the Earth, other planets, to help us communicate, and even to observe the distant Universe. The first artificial satellite was the Soviet Sputnik 1 mission, launched in
Much of the progress that mankind has made in different fields right from the stone age to the modern age is due to the progress made in the field of science. Not only material progress but also the mental outlook of man has been influenced by it.
Agriculture, business, transport, communication and medicine to name a few are all highly indebted to the wonders science has produced.
Electricity is one of the greatest wonders of modern science. It is a source of energy. It can run any type of machinery. With the help of electricity, we can light our rooms run buses and trains, and lift water for irrigation.
The discovery and development of a large number of powerful energy sources coal, petroleum, natural gas, electricity, etc. Science has given man the means of travelling cars, trains, ships, etc. Man has even travelled to the moon.
Faster means of transport can be utilized for sending food grains to victims of famine or epidemics across the globe, for transporting armed men for fighting in distant places.
Science has benefited agriculture too. The food production levels and quality have improved. Soil analysis, hybrid verities of crops, fertilizers, pesticides, advanced tools and machinery, improved irrigation methods, etc.
Today we have metrological satellites in outer space sending data and pictures to earth stations helping agriculture scientists find and analyses soil patterns. They also help them trace the progress of rains winds and even locusts that endanger crops. Satellites can even forewarn about natural calamities like hurricanes which cause mass destruction.
Man with the help of science, has been able to increase longevity, arrest the gradual decay of human body and control the spread of lethal diseases by making extraordinary life prolonging drugs and medicines.

Diseases like tuberculosis and many kinds of cancer which were considered fatal a few decades ago are no longer incurable. One of the biggest achievements of science is in the field of entertainment.
Leisure management industry, with television shows, music concerts and films, is emerging as emerging as the largest and the most important industry in the twenty first century satellite television has made it possible for millions of people to watch sporting and entertainment events taking place in different parts of the world simultaneously.
Information technology and computer have revolutionized our lifestyle. Automation in banks and railways stations has provided relief to the public and staff alike. Ticketing and reservation have become more efficient and convenient. In medical diagnosis, computers are used to locate and investigate accurately and reservation have become more efficient convenient.
In medical diagnosis, computers are used to locate and investigate accurately and precisely any abnormalities or diseases. The internet has some very useful applications in our day to day life.
Mobile phones are the outcome of information technology. But at the same time it cannot be denied that the boon in many cases has turned out to be the bane. There are innumerable examples which prove that science a blessing has been turned into a curse. Sir Alfred Nobel experience with dynamite to clear huge mountains to turn it into productive lands.
But modern man uses it to kill his fellow human beings and destroy nature. It is a fact that much of the national income of a developing country is spent on acquiring latest weapons, bombs and missiles.
Apart from atomic weapons man has also started stockpiling biological and chemical weapons. These weapons are equally dangerous.
Biotechnology is a great boon for fighting disease. But along with medicines lethal biological weapons have also been developed. Germs are deliberately released into the air to spread diseases. Anthrax envelopes are used for spreading terrorism. The negative effects of the excessive use of fertilizers and pesticides, used to increase yield are now evident.
Soil salinity has increases. Traces of DDT are found in plants.A natural satellite is any celestial body in space that orbits around a larger body.
Moons are called natural satellites because they orbit planets. A satellite is anything that orbits around a larger object.
A natural satellite is any celestial body in space that orbits around a larger body. Jun 30, · The “crazy busy” existence so many of us complain about is almost entirely self-imposed. Saturn, for example, has at least 53 natural satellites, and between and , it also had an artificial one — the Cassini spacecraft, which explored the ringed planet and its moons.
Since the conclusion is false, the reasoning is bad, or the premisses are not all true. But the reasoning is a dilemma; either, then, the disjunctive principle that it is either true or not is false, or the reasoning under one or the other branch is bad, or the reasoning is altogether valid.
Misc thoughts, memories, proto-essays, musings, etc. And on that dread day, the Ineffable One will summon the artificers and makers of graven images, and He will command them to give life to their creations, and failing, they and their creations will be dedicated to the flames.
