BIOGRAPHY : Bill Gates

William Henry "Bill" Gates III (born October 28, 1955) is an American business magnate, investor, author and philanthropist. In 1975, Gates and Paul Allen co-founded Microsoft, which became the world's largest PC software company. During his career at Microsoft, Gates held the positions of chairman, CEO and chief software architect, and was the largest individual shareholder until May 2014. Gates has authored and co-authored several books.

Gates is one of the best-known entrepreneurs of the personal computer revolution. Gates has been criticized for his business tactics, which have been considered anti-competitive, an opinion that has in some cases been upheld by numerous court rulings. Later in his career Gates pursued a number of philanthropic endeavors, donating large amounts of money to various charitable organizations and scientific research programs through the Bill & Melinda Gates Foundation, established in 2000.

Gates stepped down as chief executive officer of Microsoft in January 2000. He remained as chairman and created the position of chief software architect for himself. In June 2006, Gates announced that he would be transitioning from full-time work at Microsoft to part-time work, and full-time work at the Bill & Melinda Gates Foundation. He gradually transferred his duties to Ray Ozzie (chief software architect) and Craig Mundie (chief research and strategy officer). Ozzie later left the company. Gates' last full-time day at Microsoft was June 27, 2008. He stepped down as chairman of Microsoft, in February 2014, taking on a new post as technology adviser to support newly appointed CEO Satya Nadella.

Gates was born in Seattle, Washington on October 28, 1955. He is the son of William H. Gates, Sr. and Mary Maxwell Gates. Gates' ancestral origin includes English, German, and Irish, Scots-Irish. His father was a prominent lawyer, and his mother served on the board of directors for First Interstate BancSystem and the United Way. Gates' maternal grandfather was JW Maxwell, a national bank president. Gates has one elder sister, Kristi (Kristianne), and one younger sister, Libby. He was the fourth of his name in his family, but was known as William Gates III or "Trey" because his father had the "II" suffix. Early on in his life, Gates' parents had a law career in mind for him. When Gates was young, his family regularly attended a church of the Congregational Christian Churches, a Protestant Reformed denomination. The family encouraged competition; one visitor reported that "it didn't matter whether it was hearts or pickleball or swimming to the dock ... there was always a reward for winning and there was always a penalty for losing".

At 13, he enrolled in the Lakeside School, a private preparatory school. When he was in the eighth grade, the Mothers Club at the school used proceeds from Lakeside School's rummage sale to buy a Teletype Model 33 ASR terminal and a block of computer time on a General Electric (GE) computer for the school's students. Gates took an interest in programming the GE system in BASIC, and was excused from math classes to pursue his interest. He wrote his first computer program on this machine: an implementation of tic-tac-toe that allowed users to play games against the computer. Gates was fascinated by the machine and how it would always execute software code perfectly. When he reflected back on that moment, he said, "There was just something neat about the machine." After the Mothers Club donation was exhausted, he and other students sought time on systems including DEC PDP minicomputers. One of these systems was a PDP-10 belonging to Computer Center Corporation (CCC), which banned four Lakeside students – Gates, Paul Allen, Ric Weiland, and Kent Evans – for the summer after it caught them exploiting bugs in the operating system to obtain free computer time.

At the end of the ban, the four students offered to find bugs in CCC's software in exchange for computer time. Rather than use the system via Teletype, Gates went to CCC's offices and studied source code for various programs that ran on the system, including programs in Fortran, Lisp, and machine language. The arrangement with CCC continued until 1970, when the company went out of business. The following year, Information Sciences, Inc. hired the four Lakeside students to write a payroll program in Cobol, providing them computer time and royalties. After his administrators became aware of his programming abilities, Gates wrote the school's computer program to schedule students in classes. He modified the code so that he was placed in classes with "a disproportionate number of interesting girls." He later stated that "it was hard to tear myself away from a machine at which I could so unambiguously demonstrate success." At age 17, Gates formed a venture with Allen, called Traf-O-Data, to make traffic counters based on the Intel 8008 processor. In early 1973, Bill Gates served as a congressional page in the U.S. House of Representatives.

Gates graduated from Lakeside School in 1973, and was a National Merit Scholar. He scored 1590 out of 1600 on the SAT and enrolled at Harvard College in the autumn of 1973, chose pre-law major but took most rigorous mathematics and graduate level computer science courses. While at Harvard, he met Steve Ballmer, who would later succeed Gates as CEO of Microsoft.


Gates studied the work of Andrew Carnegie and John D. Rockefeller, and in 1994, sold some of his Microsoft stock to create the "William H. Gates Foundation." In 2000, Gates and his wife combined three family foundations to create the charitable Bill & Melinda Gates Foundation, which was identified by the Funds for NGOs company in 2013, as the world's wealthiest charitable foundation, with assets reportedly valued at more than $34.6 billion. The Foundation allows benefactors to access information that shows how its money is being spent, unlike other major charitable organizations such as the Wellcome Trust.

The foundation is organized into four program areas: Global Development Division, Global Health Division, United States Division, and Global Policy & Advocacy Division.

Gates has credited the generosity and extensive philanthropy of David Rockefeller as a major influence. Gates and his father met with Rockefeller several times, and their charity work is partly modeled on the Rockefeller family's philanthropic focus, whereby they are interested in tackling the global problems that are ignored by governments and other organizations. As of 2007, Bill and Melinda Gates were the second-most generous philanthropists in America, having given over $28 billion to charity. the couple plan to eventually donate 95 percent of their wealth to charity.

The Bill and Melinda Gates Foundation supports the use of genetically modified organisms in agricultural development. Specifically, the foundation is supporting the International Rice Research Institute in developing Golden Rice, a genetically modified rice variant used to combat Vitamin A deficiency.

Rafflesia Arnoldi

Rafflesia arnoldi is a member of the genus Rafflesia. It is one of the three national flowers in Indonesia, the other two being the white jasmine and moon orchid. It is the largest flower on earth. It has a very strong and horrible odor of decaying flesh, earning it the nickname "corpse flower". Rafflesia arnoldi is an endemic to the rainforrest of Sumatera, but sometimes we can find it in kalimantan.

Rafflesia arnoldi got its name from its founder. They are The British botanist Joseph Arnold, and the statesman Sir Thomas Stamford Bingley Raffles.

The flower of Rafflesia arnoldii grows to a diameter of around one meter (3 ft), but the greatest measurement from a reliable source is 105 centimeters (3.4 ft) for one at Palupah Nature Reserve near Bukittinggi, Sumatra. Rafflesia arnoldi can weight up to 11 kilograms. These flowers emerge from very large, cabbage-like, maroon or magenta buds typically about 30 cm (12 in) wide, but the largest (and the largest flower bud ever recorded) found at Mount Sago, Sumatra in May 1956 was 43cm (17 in) in diameter. It lives as a parasite on several vines of the genus Tetrastigma , which grow only in primary (undisturbed) rainforests. Rafflesia lacks any observable leaves, stems or even roots, yet is still considered a vascular plant. Similar to fungi, individuals grow as thread-like strands of tissue completely embedded within and in intimate contact with surrounding host cells from which nutrients and water are obtained. This plant produces no leaves, stems or roots and does not have chlorophyll. It can only be seen when it is ready to reproduce. Perhaps the only part of Rafflesia that is identifiable as distinctly plant-like are the flowers; although, even these are unusual since they attain massive proportions, have a reddish-brown coloration and stink of rotting flesh. This scent attracts insects such as flies which then pollinate the rare plant. It is not to be confused with the titan arum, Amorphophallus titanum, which is also commonly referred to as the "corpse flower" because of its repulsive odor.

When Rafflesia is ready to reproduce, a tiny bud forms outside the root or stem of its host and develops over a period of a year. The cabbage-like head that develops eventually opens to reveal the flower. The stigma or stamen are attached to a spiked disk inside the flower. A foul smell of rotting meat attracts flies and beetles to pollinate. To pollinate successfully, the flies and/or beetles must visit both the male and female plants, in that order. The fruit produced are round lots filled with smooth flesh including many thousands of hard-coated seeds that are eaten and spread by treeshrews. Elephants also affect the pollination of this flower and this type of pollination is known as Elephophily.

Rafflesia arnoldii is rare and fairly hard to locate. It is especially difficult to locate the flower in forests, as the buds take many months to develop and the flower lasts for just a few days.

Now, Rafflesia arnoldi is critically endangered plant as the number of the flower are decreasing. Many areas where Rafflesia arnoldi grows have become popular tourist attractions. While such tourism has helped locals to conserve the species, the increased human activity has disturbed and reduced flower bud production at many locations.

Wonderful Place

ayers rock in uluru national park, Northern Australia
On the latest english lesson, I make a presentation about a wonderful place in Australia called "Ayers Rock". The Ayers Rock, located in Uluru national park in the Northern Australia. Ayers Rock is a huge form of stone located in the middle of the desert. Ayers rock is about 3.6 km long and 1.9 km wide. if we want to circle it, it will be about 9.4 km.

We can get there by car from Alice Springs city, it will takes five to six ours of driving. If we want to get to the top of the rock we must walk on foot about 850 meters. or, if we want to get the aerial view of the rock, we can use helicopter tour.
