History of Titanic


 




Titanic was a British passenger liner that sank in the North Atlantic Ocean in the early morning of 15 April 1912 after colliding with an iceberg during her maiden voyage from Southampton, UK to New York City, US. The sinking of Titanic caused the deaths of more than 1,500 people in one of the deadliest peacetime maritime disasters in modern history. The RMS Titanic, the largest ship afloat at the time it entered service, was the second of three Olympic class ocean liners operated by the White Star Line, and was built by the Harland and Wolff shipyard in Belfast with Thomas Andrews as her naval architect. Andrews was among those lost in the sinking. On her maiden voyage, she carried 2,224 passengers and crew.

The Making of Titanic
The Royal Mail Steamer Titanic was the product of intense competition among rival shipping lines in the first half of the 20th century. In particular, the White Star Line found itself in a battle for steamship primacy with Cunard, a venerable British firm with two standout ships that ranked among the most sophisticated and luxurious of their time. Cunard’s Mauretania began service in 1907 and immediately set a speed record for the fastest transatlantic crossing that it held for 22 years. Cunard’s other masterpiece, Lusitania, launched the same year and was lauded for its spectacular interiors. It met its tragic end–and entered the annals of world history–on May 7, 1915, when a torpedo fired by a German U-boat sunk the ship, killing nearly 1,200 of the 1,959 people on board and precipitating the United States’ entry into World War I.


According to some hypotheses, Titanic was doomed from the start by the design so many lauded as state-of-the-art. The Olympic-class ships featured a double bottom and 15 watertight bulkheads equipped with electric watertight doors which could be operated individually or simultaneously by a switch on the bridge. It was these watertight bulkheads that inspired Shipbuilder magazine, in a special issue devoted to the Olympic liners, to deem them “practically unsinkable.” But the watertight compartment design contained a flaw that may have been a critical factor in Titanic’s sinking: While the individual bulkheads were indeed watertight, water could spill from one compartment into another. Several of Titanic’s Cunard-owned contemporaries, by contrast, already boasted innovative safety features devised to avoid this very situation. Had White Star taken a cue from its competitor, it might have saved Titanic from disaster.

That encounter took place roughly four days out, at about 11:30 p.m. on April 14. Titanic was equipped with a Marconi wireless, and there had been sporadic reports of ice from other ships, but she was sailing on calm seas under a moonless, clear sky. A lookout saw the iceberg dead ahead coming out of a slight haze, rang the warning bell and telephoned the bridge. The engines were quickly reversed and the ship was turned sharply, and instead of making direct impact the berg seemed to graze along the side of the ship, sprinkling ice fragments on the forward deck. Sensing no collision, the lookouts were relieved. They had no idea that the iceberg’s jagged underwater spur had slashed a 300-foot gash well below the ship’s waterline, and that Titanic was doomed. By the time the captain toured the damaged area with Harland and Wolff’s Thomas Andrews, five compartments were already filling with seawater, and the bow of the ship was alarmingly down. Andrews did a quick calculation and estimated that Titanic might remain afloat for an hour and a half, perhaps slightly more. At that point the captain, who had already instructed his wireless operator to call for help, ordered the lifeboats to be loaded.

CELL O MANIA

 
 
 
 
 
 
 
  1. Stay connected anytime and anywhere: The most basic benefit of a cell phone for which most of us use it is that we can stay connected with our loved ones in any part of the world and anytime. Gone are the days when we used to stand in queues to make an STD or ISD calls. You can talk to your loved ones staying even seven seas far with cell phones.
  2. SMS: When initially SMS was invented, the makers were not actually sure whether it will work. I mean when people can straightaway make a call and talk, then why would anybody like to take the pain of typing a message! But to their surprise SMSs are today the most widely used service across the world. There are many situations in which a person can’t attend a call, so all you have to do is simply send an SMS and without talking your message is delivered.
  3. Your way out in emergencies: Imagine you are stuck in a traffic jam, getting late for a meeting or your car has broken down in middle of nowhere. Cell phones are of great use in time of such emergencies. You can contact help with the use of cell phone easily.
  4. Navigation in your hand: cell phones are constantly being upgraded with new technology and the recent phones are equipped with navigation and GPRS systems. You can never get lost if you have a cell phone with navigation system. Imagine, it gives you the details of every nook and corner of your destination.
  5. Mini PC: cell phones are nowadays almost equivalent to mini computers.
  6. The latest ones are equipped with windows and internet facilities. So you don’t need to wait for the newspaper! You can simply access the internet on your cell phone and get to know about the latest news, your e-mails, movie shows and a lot more!
  7. Enhance your business: cell phones are a great help even at your business. With cell phones, you can constantly stay in touch with your employees and get to know about crucial information of your business.
  8. Help in legal matters: a lot of criminals are these days being held because of their cell phones! The police can track a criminal via tracking the place where his mobile phone is using GPS. Also checking a cell phone’s call records give vital information to the defense forces about the criminals.
  9. Wholesome entertainment: with a cell phone in your hand, you don’t need a TV or PC to get entertained. It is all in your cell phone. You can play games, listen to music, and click pictures and even record videos in your cell phone.
  10. Transfer of data: these days cell phones are equipped with infrared and bluetooth technologies which allow you to transfer data like mails, pictures, music and even videos just in span of seconds.
  11. Prestige and fashion statement: cell phones have become a matter of prestige and fashion statement, especially among the youth. If you have a latest handset then you can definitely impress others!
 
The disadvanteges of mobile phones are:it can damage your ear, its quite expensive, sometimes the reception is poor in some areas, you cant talk underground and in planes, people use bluetooth and the camera in bad ways, people use the phone while they are driving and this can couse problems. There are some disadvantages of owning a cell phone. As mentioned earlier in this unit, cell phones are those in which information is sent to one or more receiver by means of a modulated electromagnetic wave. Electromagnetic radiation can occur as a result of electromagnetic waves. The wavelength of electromagnetic wave determines its properties X-rays, infrared microwaves, radio waves and light waves . The frequency of an electromagnetic wave is the number of cycle that occurs in one second.
There are concerns about cell phones like many other electronic devices. First, the cell phone physically has non-repairable internal parts that can corrode. For example if a cell phone gets wet, you may damage internal parts. Also, extreme heat in a car can damage the battery or the cell-phone electronics and extreme cold may cause a momentary loss of the screen display. Second, analog cell phones may have problems of cloning. Cloning means someone has stolen its ID numbers and makes long distance calls on the owner's account. Third, another disadvantage of cell phones is that it does not have the ability to provide the callers location like a land line telephone. If you do not know where you are, you can not be found, if in trouble, on a cell phone. The tower can be located, but the caller can not because cells use base stations and towers to hand off calls as the user moves from one location to another. Fourth, like all electromagnetic waves, radio waves contain vibrating, electric and magnetic fields. In free space, these electric and magnetic fields are constrained to be perpendicular to each other, and to the direction of propagation. The waves can also be polarized. For example, if the electric field vibrates only in the vertical direction, the wave is vertically polarized. This polarization will not change as the wave travels through free space. In urban areas, radio waves are usually scattered by buildings and other large objects. This type of scattering effectively creates extra polarization states in all three spatial directions at a receiving antenna.

E-MAN

E-Man is a fictional comic book superhero created by writer Nicola Cuti and artist Joe Staton for Charlton Comics in 1973. Though the character's original series was short-lived, the lightly humorous hero has become a cult-classic sporadically revived by various independent comics publishers.E-Man is a sentient packet of energy thrown off by a nova. Traveling the galaxy he learned about life, how to duplicate the appearance of life, and good and evil. Reaching Earth, he met exotic dancer/grad student Katrinka Colchnzski (who attended Xanadu University), also known as Nova Kane (novocaine), and formed himself into a superhero dubbed E-Man, with a civilian identity dubbed "Alec Tronn" (electron).Nova would later be caught in a nuclear explosion and gain the same powers as E-Man and become his partner; later still, she would lose her powers and become a normal human being again, only to regain her powers sometime afterward. During their early adventures they picked up a pet koala named Teddy Q, whose intelligence grew to the point where he had a job waiting tables in a cafe.His emblem was the famous mass-energy equivalence formula "E=MC2" (postulated by Albert Einstein), and E-Man's 
powers included firing energy blasts from his hands, changing his appearance, and transforming part or all of his body into anything he could envision (e.g., turning his feet into jet engines so he could fly).

EID-UL-ADHA


 




Eid -al- Adha is an Islamic festival to commemorate the willingness of Ibrahim (also known as Abraham) to follow Allah's (God's) command to sacrifice his son Ishmael. Muslims around the world observe this event. During the celebration of Eid al-Adha, Muslims commemorate and remember Abraham's trials, by themselves slaughtering an animal such as a sheep, camel, or goat. The meat from the sacrifice of Eid al-Adha is mostly given away to others. One-third is eaten by immediate family and relatives, one-third is given away to friends, and one-third is donated to the poor.
 



On this Eid- al-Adha I got henna on my hands . Waking up early is a usual aspect of Eid. Well after the  goat was slaughtered, we headed of outside to  a long drive. After arriving home we attended to some guests. We watched   some movies with our cousins  . But the most amazing part of Eid was when we received eidi.  Hope the next Eid will be as memorable as this one.

Dignity Day


            What is meant by Dignity Day ?


Global Dignity Day is an initiative to educate and inspire young people and help them to understand their self-worth and goals. It was established in 2008 and continues to grow in popularity.
On Global Dignity Day, speakers go into schools and tell pupils about their own lives and experiences with dignity and all that that entails: self-respect, ambition, hard work, a feeling of accomplishment.
Global Dignity Day thus serves as a benchmark for children to measure their success and as a reminder of what they find truly important in life.


                                                                                                                                           
Beacon house celebrates the honors of dignity day every year by arranging school trips to different orphan houses, assemblies and  presenting the staff with gifts,cards and flowers.Educational plays and posters are presented by the students in the honors of dignity day.
