History of Ashes





The words on the original Ashes cup reads as follows :


When Ivo goes back with the urn, the urn;
Studds, Steel, Read and Tylecote return, return;
The welkin will ring loud,
The great crowd will feel proud,
Seeing Barlow and Bates with the urn, the urn;
And the rest coming home with the urn.



The beginning :

English people loved cricket. They found a rival in their own people down under - now called as Australians and started playing friendly matches.

That was the start of International test cricket as well. The year was 1877. But somewhere in between, English people missed the idea that if these cricket matches kept on going, someday they might lose as well.

That's what happened at the Oval on 29th August 1882 - the 9th test match between the two countries. Although it was just a 4 balls per over 2 day match, England team fell short by 7 runs and being the only test of the series - Australia not only won the match but the series as well.

"In affectionate remembrance of English cricket which died at The Oval, 29th August, 1882. Deeply lamented by a large circle of sorrowing friends and acquaintances. The body will be cremated and the Ashes taken to Australia." - wrote a London journalist, Reginald Shirley Brooks in a mock obituary (which means death notice). It was published by Sporting Times next day.

From that day onwards, these two countries play a test match series every 2 years. Whoever wins the series, wins the Ashes. If series is draw, Ashes remains with previous winner. 

Ashes Series


It's basically an urn (a vase of varying size and shape, usually having a footed base or pedestal) and can be seen in the cricket museum at Lord's. A red and a gold velvet bag - which were made specially for that urn and the scorecard of that 1882 test match reside along with it.

It's not known what that Ashes urn contains. Some say it has the ashes of the "bail" used in the 3rd test match when English team traveled to Australia to regain ashes after that Oval test loss. Some say it's burned ball... make your own guess..


Victory after follow-on 


Out of 1815 test matches as I write this, only three have seen teams coming back and winning after being forced to follow-on. Twice has been done by English team in Ashes series - at Sydney in 1894 and then at Leeds in 1981...

The 3rd and last miracle happened for Indian team at 
Kolkatta. Surprisingly, Australian team were always at receiving end.


Highest Totals 

Highest innings score by Australia in Ashes series is 729 for 6 declared at Lords in 1930, while their second best test innings total against England is 701 at Oval.

For England, Sir Leonard Hutton's 364 helped them reach 903 for 7 declared (the 2nd highest Innings score by any country) at the Oval, and the test victory by an innings and 578 runs - the biggest test win margin for any country against anyone. 



Lowest totalls 

Australians were bowled out for only 36 in 1902 whereas English team were polished by Turner and Ferris for 45 in a Sydney test in 1887.
The other two lowest innings scores in Ashes series is 42 & 44 by Australia and 52 & 53 for England.

War of Currents





      


 Nickola Tesla: The Genius who lit the world. Have you heard of Nickola Tesla? Surprisingly, many people still do not realize the impact his work has made on American society, and the whole world. You might be wondering, "What is the War of Currents and what does it have to do with Nickola Tesla?" Well picture this...

   Two mentalities come to a clash. One relies on the systematic proofs of trial and error. The other uses mathematical principles and theory to derive results. No booms or bangs of detonating cannons, or explosions of military camps are heard. Only the tension of conflicting beliefs, paired with the piercing buzz of electircal currents penotrating the air. The casualties? A few commoners in a freak electrical accident and some household pets. Not quite like an ordinary war? That's because it isn't. It is The War of Currents, led by the two genuises Thomas Edison and Nickola Tesla.

           In 1887, the sparks that ignited The War of Currents arose. It was a time when elctricity was lighting homes and streets all over America's cities. The energy was provided by Thomas Edison's direct current, usually referred to as DC. Edison's breakthrough was a turning point for life in America. At that point, electricity could be transmitted from its source to a light bulb ten feet away. Even more useful, power from one building would be shot down a wire to a neighboring building, sharing energy and the new luxury of light. The DC system, however, was far from perfect. DC moves only in one direction and has a constant voltage. This is a straight forward method for creating power, but the voltage tended to heat and often melt the copper wires through which it ran. This made DC transmission for distances over a mile dangerous, and sometimes impossible. Also, DC power cannot be changed by a transformer because of its unvarying voltage. Edison's solution was to merely create more wires to accomodate the needs of the city. This unfortunately caused New York to look more like a spider web rather than an industrialized city. In addition to the unattractive appearance DC imposed, hazardous effects arose as well. In the Great Blizzard of March 11-14, 1888, a total of four hundred people died. Many of those deaths were caused by an excess of collapsing DC wires that electrocuted those below. Clearly something had to be changed...          











Nickola Tesla was a man born in eastern Europe, in what is now called Croatia near the border of Bosnia. His revolutionary way of thinking presented somewhat of an opposition to Edison's DC system. Tesla invisioned a form of power called alternating current, also known as AC. He knew the faults of DC, and brainstormed a way to eliminate those problems, with an electric current of his own. AC's voltage, unlike DC, is not constant. While DC's voltage can be presented as a linear function with a constant value, AC voltage can be displayed as a sine wave. This is not as straight forward as Edison's system because one might think power is reduced when the voltage is in the negative phase of the sine wave. However, power does not rely solely on voltage; power = voltage x current. The current of AC also resembles a sine wave, being negative and positive at the same time the voltage is. So when the two negative values are multiplied, the power is still positive. Therefore, the same amount of power can be attained from the AC system, without keeping a constant high voltage that caused endless wire damage in the DC system. The most important advantage of the AC system is its ability to be modified by a transformer. With the AC system, the same line used to power a lamp can also used to power a motor. No more melting or excessive wires, no more distance restrcitions, no more DC. Tesla had outdone Edison, not by improving the DC system, but by creating a whole new electrical wonder of his own.
           
            And so the war began. It was said that Edison, well aware of his system becoming obsolete, would not accept AC because it wasn't his idea. He then launched an anti-AC campaign, describing DC as "a river flowing peacefully to the sea, while alternating current was like a torrent rushing violently over a precipice." With the help of Harold Brown, Edison would continue the battle for sales, and recognition. Brown assisted Edison's propaganda by electrocuting dogs and horses to demonstrate the "dangers" of the AC system. These string of electrocutions actually led the the development of the electric chair.
       


Tesla's only efforts in this battle were demonstrations of his efficient AC motors and transformable power. At the Chicago World's Fair in 1893, J.P. Morgan (General Electric Company) offered to power the first all-electric fair. GE was a company backing DC, and they asked for one million dollars to light the fair. This task would require massive amounts of copper wire, some for the motors, and others for the lights. Different wires had to be used because of DC's unchanging voltage. George Westinghouse was by this time, a believer and supporter of Tesla's AC system. He offered to light the fair for half the price. This was a practical offer because AC wouldn't require all the wire DC needed. So a point was won for AC and Tesla when Westinghouse was granted the contract for powering the fair.          

         GE's retaliation was to ban the use of Edison's lamps for Westinghouse. This was a small obstacle for Tesla and Westinghouse, as they once again paralyzed the public in awe at the Columbian Exposition later that same year. They were chosen over Edison's DC system to power the fairgrounds and win the appreciation of spectators and energy users of the country. It didn't take many more displays of superiority for AC to be renowned as the more efficient power source. Soon after, 80% of all electric devices in the U.S. were for alternating current. Finally, the AC system was recognized as the invention that would light the future.

with ur parents or ur teachers abt ur fears and 
doubts.


create a schedule- organise ur time and prepare 4
the exam.


Do ur exam revisions alone or with ur friends.


test ur knowledge with friends.


Meet friends and try askin questions to each other.




How to beat fear?


Learn to face the exam.Dispute ur fear of failure.





Attempt a mental representation of the actual conditions
tat cause u stress(imagine in detail the actual conditions
tat make u feel stressed).When u do this exercise, u will 
notice tat the more u imagine and visualize the exams,
the more familiar u think they are.When u can deal with
ur fears in ur imagination,u can deal with them in reality
as well.


Will an inappropriate study environment cause stress?


Create a pleasant study environment without strong 
lightening and noise.




Make sure tat the room has enough fresh air,
Close windows and down the rolls;




Turn off the T.V, radio and cell phone.If there
is still noise tat could distract u,use ear plugs


Find comfortable places to study
