Philip Carteret
Philip Carteret (22 January 1733 – 21 July 1796) was an English officer in the Royal Navy. He sailed as a lieutenant on John Byron's circumnavigation (sailing around) of the world in 1764. He went around the world again as part of the Royal Navy's exploration in 1766.
Carteret joined the Royal Navy in 1747 at the age of 14. He first served on the "Salisbury". He sailed with John Byron from 1751 to 1755. As Lieutenant on "HMS Doplhin", he went with Byron on the round world trip from 1764—1766.
As soon as he had returned from his first trip, Carteret was put in charge of "HMS Swallow" to go on a second circumnavigation with Samuel Wallis who sailed in the "HMS Dolphin". The two ships were separated sailing around Cape Horn, so Carteret continued on alone. He discovered Pitcairn Island on 2 July 1767. He did not land on the island. He also discovered the Carteret Islands, Mururoa, and the Duke of Gloucester Islands. He got back to England in 1769. The "Swallow" was in bad condition and the success of the long trip shows Carteret's courage and skill.
Carteret's health was ruined by his voyage of exploration. He was put on half pay, and in 1773, he wrote the story of the voyage as part of a book about the voyages of Byron, Wallis, Carteret and Cook. The book's editor John Hawkesworth, made changes to the story, so Carteret wrote his own book which was not printed until 1965. In 1779 he took the ship "HMS Endymion" to the West Indies. This was his last trip. He was promoted to Vice-Admiral and he retired to Southhampton in 1794. His personal papers are kept in the National Maritime Museum in Greenwich, England.

Fold mountain
Fold mountains are mountains formed mainly by the effects of folding on layers in the upper part of the Earth's crust. The term is rather out of date, though still fairly common in physical geography literature.
In the time before plate tectonics became well understood, the term was used for mountain belts, such as the Himalayas. These mountain ranges are "not" caused by the folding of the earth's crust. The main mechanism causing a thickening of the crust at these sites of continent-continent collision along boundary is thrust faulting.
Fold mountains are formed when two tectonic plates move together (a convergent plate boundary). Fold mountains are usually formed from sedimentary rocks which accumulated along the margins of continents. When plates and the continents riding on them collide, the accumulated layers of rock may crumple and fold like a tablecloth that is pushed across a table, particularly if there is a mechanically weak basal layer such as salt.

Boris Berezovsky
Boris Abramovich Berezovsky (23 January 1946 – 23 March 2013) was a Russian-British business man, billionaire, and former mathematician. He was best known for the powerful positions he held in the 1990s when Boris Yeltsin was president of Russia.
Berezovsky was deputy secretary of Russia's security council, and a friend of Boris Yeltsin's daughter Tatyana. He had a lot of power over what the newspapers were allowed to print and what the television stations could say. They were not allowed to say anything bad about Yeltsin.
Berezovsky made his fortune importing Mercedes cars into Russia in the 1990s. He made a lot of money from Avtovaz cars and he owned the Sibneft oil company.
When Putin came to power Berezovsky fled to London where he was given political asylum. He said that he was trying to put an end to Putin's power. The Russian authorities accused him of trying to murder several leading critics of Putin's regime, including Alexander Litvinenko and journalist Anna Politkovskaya, in order to make Putin look bad. The Swiss accused him of taking money illegally.
In 1994 someone tried to kill Berezovsky. Several other people may have tried to kill him. He said these people were Russian agents.
Berezovsky died on 23 March 2013 in Sunninghill, Berkshire, England, aged 67. He lived in London, England. On March 25, police said that his death was caused by hanging. There were no signs of a struggle.
On 23 March 2013, Berezovsky was found dead at his home. His body was found by a bodyguard in a locked bathroom, with a ligature around his neck. His death was announced in a post on Facebook by his son-in-law. Alexander Dobrovinsky, a lawyer who represented Berezovsky, wrote that he may have committed suicide. He added that Berezovsky had fallen into debt after losing a protracted lawsuit against Roman Abramovich, and had spent the last few months of his life selling his possessions to cover his court costs. Berezovsky was also said to have recently been depressed and to have isolated himself from friends. He reportedly suffered from depression and was taking antidepressant drugs. A day before his death he told a reporter in London that he had nothing left to live for.
When Berezovsky's death became known, there was speculation by mainstream British news media that Moscow might be somehow involved. The Thames Valley Police classified his death as "unexplained" and launched a formal investigation into the circumstances behind it. Specialists in chemical, biological, radiological and nuclear materials were sent to Berezovsky's home as a "precaution". These specialists later "found nothing of concern".
A post-mortem examination carried out by the Home Office pathologist found the cause of death was consistent with hanging and there was nothing pointing to a violent struggle. However, after an inquest into the death in March 2014 the coroner, Mr Peter Bedford, recorded an open verdict commenting, "I am not saying Mr Berezovsky took his own life, I am not saying Mr Berezovsky was unlawfully killed. What I am saying is that the burden of proof sets such a high standard it is impossible for me to say".
Despite his death in March 2013 Berezovsky's Interpol Red Notice continues to remain active.
