1. Simple Repitition Method
The classical method, very popular as in committing poems to memory by reading them over and over.
2. Full Concentration Method
Concentrate on the topic content while learning. Do not allow your mind to wander. Focus on names and numbers. Try deliberately to remember. Your approach should not be casual. Review soon after you learn, lest memory should fade away.
3. Visual Encoding Method
Translate information into visual formats like pictures, charts, diagrams, tables and graph.
4. Logical Organisation
Matter that is logically organised is retained better than the disjointed floating bits of information. Infuse meaning into what ever you learn. No “Nonsense Syllables”.
5. Mnemonics Method
Few good people try this method to learn some complicated series. There is no harm in using memory crutches like it, after grasping the spirit of the lesson. VIBGYOR is the most famous mnemonic that helps up to list the seven rainbow colors in their appropriate order. Once, I had remembered the name of the planets in the order of their distances from the sum by the acrostics “My very enlightened mother just served us noodles-in plates”, as it tells me the names of nine planets ( off course now they are eight, but I learned it earlier than the removal of pluto), in the order: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
6. Mock Teaching Method
If you find a particular portion of a chapter difficult to digest, imagine that you are teaching to a student sitting before you. Explain virtually the content of the lessen. The idea will get hammered into your mind.
7. Rhyming Method
Scholars say that verses are better than prose. Change any definition into verse and try to rhym them. Remember, I discuss just verses, and not poetry.
8. Chunking Method
Very popular method. You can divide a big list into a number of bits or chunks. For example, to remember a mobile number of ten digits, people usually split it to three or more chunks.
This involves the principal of association. First make a list of ten or twenty convenient pegs or key words that you can easily recall in the right sequence. For example, in alphabetical order, ant, butterfly, cat, dog, elephant, fox, and so on (Living beings are arranged). Cartoons also help in pegging.
This is the best method for that student, who want to learn very complicated topics. When you blog about any topic, you use all the nine methods listed above in your post. I got blogging, superior method to other nine.
- What is an easy way to remember the planets (wiki.answers.com)
“I have grown, looking at sky and stars.” Many people can say this, including me. We loved to watch stars in night. We enjoyed the Sunrise and Sunsets. And offcourse, millions of people loves NASA’s Astronomy Pic Of the Day and they like to add APOD as their wallpapers. There are many more beautiful phenomena in the universe, like Solar Eclipse, Eagle Nebula, Aurora etc. We feel safe, cheer and enjoy our life. However, it does not mean that a smaller strike of any tragedy cannot happen even as you are reading this blog. For a horrible example, who was knowing about the latest Tsunami in Japan, before the date it occured?
The theory of gravity is not enough developed that you can exactly state the motion of a planet or star or any other material in the space. Some bodies, like dwarf planets, sattelites, meteoroids, have random motions. The most fearful motion is of meteoroids, the rock like structures. Usually these are found in between Mars and Jupiter as a belt. But when a meteoroid leaves the belt, the gravitational attraction of the earth, nearest planet to mars, can pull that into it. When a meteoroid enters the atmosphere, friction causes it to heat up and glow. Then we call it a shooting star or a meteor. Small meteors burn up completely as they pass through the atmosphere. Larger ones end up on earth as meteoroid. Impact craters are formed when a large meteoroid or comet crashes into a planet. One such massive natural hazard happened in past, which destroyed all the Dinosaurs.
When the photo was shown on CNN, [See Image1] hundreds of calls came in from people reporting — they could see a face in the cloud. When the color of the photo was adjusted, a large human form seemed to appear within the cloud. [See Image2]

What is the ‘Need’ of this Clean Technology?
Why Not? There is a desperate need to meet the challenges caused by climate change and environmental degradation. In the past, it was the entrepreneurial spirit that contributed most to the innovations with far reaching benefits. Besides, scientists from outside the industry innovated technologies like steam power, the railways, telegraph, radios and telephone, petroleum, the automobile, computer, internet etc. etc. Yet the role of entrepreneurial innovation in addressing environmental problems has recieved relatively little attention. In this context, presently, the clean technologies have emerged.
Why is this Techology Clean?
Clean Technologies are technologies that use energy, water, raw materials and other inputs more efficiently and productively, create less waste or toxicity, deliver equal or superior performance, and improve customer profitability, through cost reduction and/or increased revenues. Such technologies are found in a broad range of industries, including energy, water, manufacturing, advanced materials and transportation.
Why We Should Use It?
With the decrease of available energy sources; like, petroleum, coal etc., demand for energy worldwide going through the roof and after poor effects of global warming, manufactures realise that alternatives are serious business.
Convergence of environmental, technological, economic and social factors will produce more resource-efficient technologies that will be less reliant on obsolete, polluting technologies.
Clean technology is an intrinsic part of a sustainable economy. Over the past few years, the importance of developing clean technologies has grown significantly and has driven the growth of what are now multi-billion dollar markets. Globally wind energy market was valued at $5 billion in the begining of 21st century, are expected to grow to $550 billion by next year, while solar energy is expected to note from $3.5 billion to $28 billion by the same timeperiod.
The measure share of the climate change in the outlook towards clean technologies has been due to the increasing realisation that this is not merely a social responsibility requirement, but also yield amazing profits.
The result of this awareness is steadily evolving into a sustainable new economy, which is based on premises of clean energy, transportation, water and materials that embody the emerging principles of industrial ecology, resource productivity and natural capitalism. Industrial houses, corporates, as well as goverments are now investing in research and developement on environment-friendly technologies.
There is a need in developing countries to have easy access to the technologies and cheaply. For any major change, changing political understanding on such issues, government support and prospects for business involvement is critical. For the advance of clean technologies require adequate and reliable R&D budgets, better incentive systems to promote and support clean-tech purchases by businesses and competitive price for consumers. A robust economy is as much required for encouraging clean tech investments. And That’s All.
What does “The Solar System” mean?
The Solar System means the system of the Sun. All bodies under the gravitational influence of our local star, the Sun, together with the Sun, form the Solar System.
Bodies? What kind of bodies?
•The largest bodies, orbiting the Sun, including Earth are called planets.
•Often smaller cool bodies called satellites or moons, orbit a planet.
•Bodies smaller than than the planets that orbit the sun are classed as
asteroids if they are rocky or metallic, comets if they are mostly ice and dust, and meteoroids if they are very small. Most comets release gases as they near the heat of sun, producing a luminous cloud called coma & often a long tail. A meteoroid that burns in Earth’s atmosphere is a meteor, while one that reaches Earth without burning completely becomes a meteorite.
• After the exclusion of Pluto from the planet category, a new category is formed: Dwarf Planet.
Elements of Solar System:
Stars: (1) The Sun
Planets: (8) Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
Dwarf Planets: (4) Pluto, Charon, Eris, Ceres- along with the numerous satellites that travels around most of planets.
In this article, I shall discuss about the Sun only. Further bodies will be discussed in Part IV & V. While, next Part i.e. PART III, will bring you into the interior of Sun. I suggest you again to read Part I of this Series.
SnapShots & facts about the Sun:
• Sun is one of more than 100 billion stars in the giant spiral galaxy called the Milky Way.
• Sun is the center of the solar system. Its mass is about 740 times as much as that of all the planets combined.
• It continuously gives off energy in several forms- visible light; invisible infrared, ultra-violet, X-rays and γ -rays, cosmic rays, radio waves and plasma.
•The Sun generally move in almost circular orbits around the galactic center at an average speed of about 250 km per second.
•It takes 250 million years to complete one revolution round the center. This period is called a Cosmic Year.
•It’s energy is generated by nuclear fusion in its interior. It is calculated that the Sun consumes about 4million tonnes of hydrogen every second. At this rate, it is expected to burn out its stock of hydrogen in about 5billion years and turn into a red giant.
