If you thinking to drive in India, BEWARE!!!!!!!!!!

I found the following interesting video hope this interest you.

The Size of The Sun or Earth

It is the fire of life. It can be kind but it can get angry. But it never throws its weight around. It is the sun. And although it is 330,000 more massive than earth and contains 99.8% of the mass in our solar system, it is small in comparison with some other stars.

The sun never cease to amaze us with its theatrics, its lava flares dancing across its surface in a ballet of nuclear fusion, sometimes leaping millions of miles into the air. And although the sun is big, its intense heat and light makes it difficult to capture good images with normal instruments. So NASA scientists use an Helioseismic and Magnetic Imager and an Atmospheric Imaging Assembly detector to view the ultra-violet (UV) and extreme ultra-violet lithography (EUV) wavelengths released by the sun. The resulting images are spectacular.

Earth in comparison to the sun

Earth’s distance from the sun varies between 91.4 million miles – in January – and 94.4 million miles – in July. The average distance of 92,955,887.6 miles (149, 597, 870.7 kilometers) is called 1 astronomical unit (AU), a measurement that is used to report distances to other planets and stars as well. In short, it’s not a weekend drive.

NASA puts the size of earth to the sun in perspective like this: Suppose the radius of Earth were the width of an ordinary paper clip. The radius of the sun would be roughly the height of a desk, and the sun would be about 100 paces from earth.

Earth size in comparison to the sun and other planets:

(Hey, we’re small but we’re beautiful!)

The size of the sun in comparison

Our sun is one of billions in the entire universe. It also is fairly small in comparison with other big stars. In fact, our sun is classified as a G2 dwarf star. Sirius, the brightest star in the night sky, is twice as massive as the sun and 25 times more luminous. And Sirius is dwarfed by Pollux, which is eight times the radius of the sun. And Pollux is dwarfed by Arcturus, which is almost 26 times the size of the sun.

It’s a big, big universe

But there are bigger stars yet. When compared to Antares, our handsome sun is a mere pixel on a map. And Antares is not even the biggest star. That title is thought to belong to a star called VY Canus Majoris. It is about 2,000 times the size of the sun, or more than twice the size of Antares.

Sun in comparison to Antares:

Note that it VY Canus Majoris is the biggest in size but not mass. The currently known most massive star is thought to be WR 102ka – known as Peony Nebula Star – at about 175 times the mass of the sun.

How big is the universe?

The Wilkinson Microwave Anisotropy Probe calculated the age of the known universe at 13.7 billion years old, based on its radius of 13.7 billion light years. And it is growing bigger every day, at a speed of 71 km/s/Mpc. The size of the whole universe is estimated to be 78 billion light years. If you start traveling today at 60 miles per hour (100km/h) you’ll get to the end of your first coffee stop, the end of one light year, in nine trillion years. Then you just keep going for another 77 billion light years. Or you could stay here, look after our beautiful planet… and enjoy the sun.

Qualitative Research and Quantitative Research

Qualitative research

is a type of scientific research. In general terms, scientific research consists
of an investigation that:
• seeks answers to a question
• systematically uses a predefined set of procedures to answer the question
• collects evidence
• produces findings that were not determined in advance
• produces findings that are applicable beyond the immediate boundaries of the study
Qualitative research shares these characteristics. Additionally, it seeks to understand a given
research problem or topic from the perspectives of the local population it involves. Qualitative
research is especially effective in obtaining culturally specific information about the values,
opinions, behaviors, and social contexts of particular populations.

Examples Of Qualitative Research
Complex Data, Meaning, Understanding, Interpretation, Representative perspective sample, Exploratory etc.

Quantitative Research

Quantitative research is the numbers game. It’s about measurement and attaching numbers to a market – for instance market size, market share, penetration, installed base and market growth rates.
Quantitative research can also be used to measure attitudes, satisfaction, commitment and a range of other useful market data and market metrics that can tracked over time and used as part of a wider business planning and business strategy process.

Examples Of Quantitative Research

Numeric data, Measurement, Explanation, Prediction, Representative population sample etc.

Thinking about my area of interest :)

Four Things I know
 This is internet based computing
 There are some companies who are providing cloud computing
 Cloud computer providers deliver common business applications
 Companies who are providing cloud computing (Top 10)

Four Things I don’t know
 Its benefits
 Its problems
 Is this affecting manufacturer of Networking gears
 Is this affecting IT professionals

Four Things I believe
 With the use of this companies may save money, because there is no need to buy costly networking gears.
 Cloud computing providers have full control over the customer’s (Company) data and they can use private data or can exchange useful information with other companies.
 Companies which are using cloud computing will cut IT professional jobs.
 I believe that a person who has minimum knowledge can operate it.

Areas of Interest

Well if we talk about my interest, as I am a IT student so this is my interest, buy I was asked to think at least two topics of my interest. I am thinking that if you want to learn something you will definitely get engage with this and this cannot possible without having interest. There are two topics popped in my mind in which I want to know more.
1. Cloud Computing: – Well at the moment I don’t know much about it. But when a question is asked about the issues with cloud computing and then I thought about this so deeply so this is looking interested for me. As I am doing networking I know that with the help of this there is no need to buy costly equipment and you can save money. …….. There are many questions popping up in my mind like its benefits, risks, who will suffer and many more.

2. As I am from India so I want to compare something, what I am getting here and what was in my native country. As talking about my second interest I want to compare the ISPs services in New Zealand and India.

What are the main security issues associated with ‘cloud computing’?


I think Scientific paradigm would be best for this.

Which ISP in NZ gives the best value for money?


I am thinking about Creative Arts Paradigm.

Why don’t many school students (16-18yrs old) choose to study IT at Polytechnic or University?

Already Choosed Career(They are choosing)
I think Social Science Paradigm is the best way to approach this
