What is powerplay in the cricket world cup? |
| Question found in Cricket |
 |
|
Powerplay is a rule in cricket which was introduced in 2006 and it is in regard with the fielding restrictions in One-Day International cricket. It was included in international cricket laws in accordance with some suggestions from Indian cricketer Sunil Gawaskar. After it was implemented in a trial basis during 2006, this law is now finalized and is included as a rule in the 2007 ICC World Cup. In the very early days of Oneday cricket there were no fielding restrictions. Then, around the World Cup in 1996, ICC introduced the 15 over field restriction rule. According to this rule it was obligatory that during the first 15 overs of each innings, only two fielders should be allowed outside the inner circle around the wicket (also called 30 yard circle). It also required two close catching fielders, i.e. fielders positioned 15 yards from the batsmen, to be set during these 15 overs. This rule is now replaced by the power play rule. I am stating the power play rule below: The fielding restrictions for an innings will be for 20 overs. 1. The first 10 overs of an innings is called Power Play One. The fielding restrictions during this period are exactly the same as per the old ODI rules with only two players being allowed to stand outside the 30-yard circle and two fielders required to be placed in close catching position. 2. The remaining 10 overs shall be taken at the discretion of the fielding captain in 2 blocks of 5 at any time in the innings thereafter. The fielding captain shall advise the on-field umpires accordingly. These two blocks are called Power Play Two and Power Play Three. The fielding captain has to decide at which point he wishes to implement this rule. He can only implement it at the beginning of an over, provided he informs the umpire. Only two fielders are allowed outside the 30-yard circle. However there is no mandatory number of close catchers under this power play. If the captain delays to start the second and third power play until 41st over or 46th over the remaining overs are automatically taken as power play. The first match to be played with this rule in effect was between England and Australia on 7 July 2005. |

How long was Liverpool banned and the rest of English clubs after the Heysel riot? |
| Question found in Football In General |
|
|
This incident known as Heysel Stadium Disaster occurred on the 29th May 1985 when Liverpool F C (English) played Juventus F C (Italian) in the European Cup Final held at the Heysel Stadium in Brussels, Belgium. The stadium resembled a war zone after the incident. According to the witnesses the violence had started long before the scheduled kick-off. The stadium was buzzing with songs and skirmishes and an extraordinarily hostile atmosphere between the two sets of fans. The hostility was explained by some Liverpool fans as payback for the final in Rome the previous year, when Liverpool had beaten the home side on penalties. Shortly before kick off the atmosphere turned violent and Liverpool supporters stampeded through a thin line of police towards the rival fans. As the Juventus fans retreated, a wall collapsed under the pressure and fans were crushed and trampled to death in the panic. Police at the scene were unable to contain the violence and riot police were called in to calm the situation. As the full extent of the tragedy unfolded the Red Cross moved in to treat the injured in tents set up at the scene. A priest was also called to give the Last Rites. There were 58,000 fans in the ground and, 39 Juventus football fans were killed, and over 350 were injured. Despite protests from both team managers the game went ahead with Juventus winning 1-0 thanks to a second half penalty. Liverpool fans were found guilty for the incident and as a consequence all English Clubs were banned from European competitions for 5 years, with Liverpool receiving a further 2 year ban. |

How did James Weddell get educated? |
| Question found in Animals & Nature |
|
| Captain James Weddell, a Scottish sealer, had no practical education when he first went to sea. The first few years at sea gave him little opportunity for educating himself, but he made the most of any opportunities that presented themselves. He was fond of reading and on board the Rainbow (a frigate in which he was held as a prisoner, guilty of insubordination and mutiny) managed to improve himself so far that he was rated as a midshipman. As a midshipman he had more time an opportunities for study and reading such that he displayed himself a capable navigator and in December 1810 was appointed master of the Firefly. |

Why is the sky blue? |
| Question found in Animals & Nature |
|
|
The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere. This scattering is called Rayleigh scattering. Almost all of the Transmitted light, be it sunlight or light from light bulbs or fire, is made up of a spectrum of colors. The colors have different wavelengths, frequencies, and energies. The longest wavelengths of light are on the red end of the spectrum and the shortest wavelengths are on the blue/violet end of the spectrum. The colors blend continuously into one another. We can see the different colors of the spectrum by splitting the light with a prism. The spectrum is also visible when you see a rainbow in the sky. The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is a mixture of many types of gases, moisture, solid particles like dust soot etc. Light travels through space in a straight line as long as nothing disturbs it. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule. Then what happens to the light depends on its wave length and the size of the thing it hits. When light hits a dust particle or water droplet being much larger than the wavelength of visible light they reflect light in different directions. The different colors of light are all reflected by the particle in the same way. The reflected light appears white because it still contains all of the same colors. When light hits gas molecules (their wavelength is smaller than visible light), it gets absorbed and released in a different direction. The color that is radiated is the same color that was absorbed. The different colors of light are affected differently. All of the colors can be absorbed. But the higher frequencies (blues) are absorbed more often than the lower frequencies (reds). This process is called Rayleigh scattering, named after Lord John Rayleigh, an English physicist, who first described it in the 1870's. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue. As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white. |

Do geisha's still exist in Japan, in which number, and how are their conditions of life? |
| Question found in Cultures In General |
|
|
Geisha are female Japanese entertainers who are skilled in a wide variety of Japanese art forms. Geisha's are a traditional symbol of Japan and they have the same importance as Samurais in Japanese culture. Geisha are often hired to attend parties and gatherings, traditionally at tea houses (ochaya) Geisha's still exist in Modern day Japan, but the role they play in modern society is minor. This tradition is facing a decline in Japan and the declining interest in the traditional arts along with the expense involved in hiring a Geisha in the sluggish economic scenario is contributing to this decline. Modern geisha still live in traditional geisha houses called okiya in areas called hanamachi or "flower towns". Young women who wish to become geisha now most often begin their training after completing junior high school or even high school or college, with many women beginning their careers in adulthood. Geisha still study traditional instruments like the shamisen, shakuhachi (bamboo flute), and drums, as well as traditional songs, Japanese traditional dance, tea ceremony, literature and poetry. By watching other geisha, and with the assistance of the owner of the geisha house, apprentices also become skilled in the complex traditions surrounding selecting and wearing kimono, and in dealing with clients. Nowadays geisha enter the profession voluntarily, rather than involuntary as children. At the end of the night they go home to their own apartments, so the life is much less rigorous and much more free than it was. In today’s Japan for a westerner it is not easy to come across a real Geisha and those they gain access to are maiko - apprentice geisha's, almost as revered as their masters. Kyoto has some traditional Geisha's but outside Kyoto it is not easy to find one. Today it is supposed that there are a total of about 1000 to 2000 Geisha in Japan. |

What is Aminopterin? |
| Question found in Animals & Nature |
|
|
Aminopterin is a folic acid antagonist used as an antineoplastic (drugs that inhibit and combat the development of tumors) in the 50s and 60s.It is a synthetic derivative of pterin. The immunosuppressive properties exhibited by Aminopterin made it to be used in chemotherapy. It is now replaced by methotrexate in the later 1950s due to unpredictable toxicity. This agent was also used to produce abortion in women in the early 1950s but was also a culprit in the congenital malformations. As our expert mistakenidentity stated it is also used as a rodenticide or a poison against rats but it is not approved for that use in Canada or the United States. |
