Dark Flow

Astronomers have a problem, galaxies are not moving in the sky the way they should. There is a mysterious object known as the "great attractor" which is termed a "gravity anomaly" as it is the origin of a large amount of gravitational force. Unfortunately, this gravitational anomaly is hiding behind the Milky Way, so we cannot really observe it too well as our own galaxy obscures it. Dark Flow is a related concept, only much larger than the great attractor. There is some mysterious force, at the edge of the visible universe, that is sending entire galaxies hurtling along at nearly 3.2 million kilometers per hour. The great attractor has a known influence of at least fifty thousand Milky Ways, but the Dark Flow anomaly is greater. Dark Flow is gravitational influence from outside the observable universe.

Hip Hop Dance and Rap Music

The origin of hip-hop can be traced back as far as the ancient tribes in Africa. Rap has been compared with the chants, drumbeats and foot-stomping African tribes performed before wars, the births of babies, and the deaths of kings and elders. Historians have reached further back than the accepted origins of hip-hop. It was born as we know it today in the Bronx, cradled and nurtured by the youth in the low-income areas of New York City.

Hip-hop dance refers to social or choreographed dance styles primarily danced to hip-hop music or that have evolved as part of hip-hop culture. This includes a wide range of styles notably breaking, locking, and popping which were developed in the 1970s by Black and Latino Americans. What separates hip-hop dance from other forms of dance is that it is often freestyle (improvisational) in nature and hip-hop dancers frequently engage in battles—formal or informal freestyle dance competitions.

Cryogenic Engine

A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel or oxidizer, that is, its fuel or oxidizer are gasses liquefied and stored at very low temperatures.Notably, these engines were one of the main factors of the ultimate success in reaching the Moon by Saturn V rocket.

During World War II, when the powerful rocket engines were first considered by the German, American and Soviet engineers independently, all discovered that rocket engines need high mass flow rate of both oxidizer and fuel to generate a sufficient thrust. At that time oxygen and low molecular weight hydrocarbons were used as oxidizer and fuel pair. At room temperature and pressure, both are in gaseous state. Hypothetically, if propellants had been stored as pressurized gases, the size and mass of fuel tanks themselves would severely decrease rocket efficiency. Therefore, to get the required mass flow rate, the only option was to cool the propellants down to cryogenic temperatures (below −150 °C, −238 °F), converting them to liquid form. Hence, all cryogenic rocket engines are also, by definition, either liquid-propellant rocket engines or hybrid rocket engines.

Big Bang Experiment

A new era began for the scientific community on Tuesday 30 March`10 as the much delayed 'Big Bang' experiment kicked off successfully after a delay of 18-months. The protons have been successfully collided inside the Large Hadron Collider (LHC) in Geneva and the experiment has been declared successful.The collider, which occupies a 17-mile (27km) circular tunnel 100m beneath the French-Swiss border, accelerated two counter-rotating beams of protons to an unprecedented energy of 3.5tn electron volts (TeV).The experiment was first initiated on Sep 10, 2008. Just nine days later on Sep 19, 2008 the experiment hit a massive road block as freezing helium gas leaked out. This led to the experiment being delayed for over a year.

Satyaki Bhattacharya, a Delhi university professor who has been involved with the experiment, said in New Delhi, that the scientists were on a hunt to detect the elusive Higgs boson which is considered as a missing link in the Standard Model of particle physics.

Some Facts About Large Hadron Collider

● Although built to study the smallest known building blocks of all things – particles – the Large Hadron Collider is the largest and most complex machine ever made. It contains 9,300 magnets and has a circumference of 27km (17 miles)

● At full power, trillions of protons race around the LHC accelerator ring 11,245 times a second, travelling at 99.99 per cent of the speed of light. It is capable of engineering 600m collisions every second


● To avoid colliding with gas molecules inside the accelerator, the beams of particles travel in an ultra-high vacuum – a cavity as empty as interplanetary space

● The cooling system circulates super-fluid helium around the LHC’s accelerator ring and keeps the machine at minus 271.3 degrees Celsius

● When two beams of protons collide, they generate temperatures more than 100,000 times hotter than the heart of the sun, concentrated within a miniscule space

● To collect data of up to 600m proton collisions per second, physicists and scientists have built electronic trigger systems to measure the passage time of a particle to a few billionths of a second

● The data recorded by the LHC’s big experiments will fill about 100,000 dual-layer DVDs every year. Tens of thousands of computers have been harnessed in a network called The Grid that will hold the information

● Thousands of scientists around the world will collaborate on analysing the data over the next 15 years (the estimated lifetime of the LHC)

Sikar

Sikar is my home town. Sikar is a historical city and at present district headquarter. Sikar presents a good many facts for the tourists. The word Sikar has a meaning of "a dew drop" (oas ki ek boondh). It is escorted all around by the highwalls comprising of seven gates. The primitive name of Sikar was ‘Beer Bhan Ka Bass’. Sikar was the kingdom of royal Shekhawat rajas. Today also many royal Shekhawat family reside in Sikar. One of the great shekhawat is Mr Bhairon Singh Shekhawat, former Vice President of India is also belong to (Khachriyawas) Sikar. Three most prominent business homes of the country viz. the Bajajs, the Birlas and the Goenkas also belong to the district.
Sikar is a very fascinating and charming place for the tourist. The fresco Painting on the ancient havelies, temples and forts captivate the tourist from abroad.

Khatushyamji is located 65 Km. away from SIKAR & 80 Km. from Jaipur via Reengus.
This little village is famous for Shyamji Temple built with white marbles.








Harshnath Temple is 14 km. away from SIKAR is an ancient site famous for the ruins old Shiva Temple (10th Century) located on the high hills of Aravali. The architectural display of the old temple is breath taking .

Nazca Lines

The Nazca Lines are a series of ancient geoglyphs located in the Nazca Desert of Peru. The high desert of Peru holds one of the most mystifying monuments of the known world—the massive-scale geoglyphs known as the Nazca Lines. Ranging from geometric patterns to “drawings” of different animals and stylized human-like forms. Could these geoglyphs be effigies of ancient animal gods or patterns of constellations? Are they roads, star pointers, maybe even a gigantic map? If the people who lived here 2,000 years ago had only a simple technology, how did they manage to construct such precise figures? Did they have a plan? If so, who ordained it? It all seems so otherworldly. To comprehend the Nasca lines, created by the removal of desert rock to reveal the pale pink sand beneath, visitors have proposed every imaginable explanation - from runways for spaceships to tracks for Olympic athletes, from op art to pop art, to astronomical observatories.

It is believed that the geoglyphs were built by a people called the Nasca- but why and how they created these wonders of the world has defied explanation.

Happiness

One of the article that I was reading makes me feel good. So I am taking some of the important points of it in my blog. As really happiness is among the most important aspect of our life and we tries to find happiness in several events around us.

Happiness As I see it

What makes you happy? Lots of money? No! then good health or Fame, power? Well happiness depends on neither of them. You can be happy without all of them.

It is a mental state. Great ascetics were supremely happy so much so that we have not experienced even a fraction of it.

You can always contradict by saying that how lack of money will make me happy.

Now think, does happiness lies in money or the things it can get us. It is in the comforts that it can give us.

You can be supremely comfortable yet unhappy. See the lives of film-stars . They have a lot of money but are very lonely. Money can buy you many things but not love.

Love and faith give happiness. When you were a child you got unconditional love from your parents. Faith in HIM makes us happy and takes burden off our shoulders.

When you are simple in thoughts and actions you feel light and happy.

What gives you happiness can be a cause of great suffering for the others.

e. g When you eat and enjoy meat some body has to pay it for its life and endure great suffering.

So what is the formula of happiness.

Here are some of the key points that we can keep in mind to remain ever happy.

1. Never hurt others. As you do to others is done to you.

2. Love unconditionally.

3. Try to find happiness in simple things. e.g. beauty of a garden.

4. Keep your ego under check. It is the source of unhappiness.

5. Have faith and live by it.

6. Meditate regularly.

7. Get plenty of exercise.

8. Be loyal to your spouse.

9. Live within your means.

10. Share your happiness with others.

Hope the above steps will keep you happy always.

Well this is my first blog and i hope that in the future i will make a good contribution in blogging.
I am a technical student and being a technical may be my blogs have more discussion about technical things but I will also try to write other things too.
