Who Is Stephen Hawking?

Stephen Hawking (born January 8, 1942) is a British scientist, professor and author who has done groundbreaking work in physics and cosmology, and whose books have helped to make science accessible to everyone. At age 21, while studying cosmology at the University of Cambridge, he was diagnosed with amyotrophic lateral sclerosis (ALS). Part of his life story was depicted in the 2014 film The Theory of Everything.

Stephen Hawking’s Books

Over the years, Stephen Hawking has written or co-written a total of 15 books. A few of the most noteworthy include:

‘The Grand Design’


‘A Briefer History of Time’




'A Brief History of Time'




The Grand Design’




What Disease Does Stephen Hawking Have?


At the age of 21, Stephen Hawking was diagnosed with amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease). In a very simple sense, the nerves that controlled his muscles were shutting down. At the time, doctors gave him two and a half years to live.

Hawking first began to notice problems with his physical health while he was at Oxford—on occasion he would trip and fall, or slur his speech—he didn't look into the problem until 1963, during his first year at Cambridge. For the most part, Hawking had kept these symptoms to himself. But when his father took notice of the condition, he took Hawking to see a doctor. For the next two weeks, the 21-year-old college student made his home at a medical clinic, where he underwent a series of tests.
"They took a muscle sample from my arm, stuck electrodes into me, and injected some radio-opaque fluid into my spine, and watched it going up and down with X-rays, as they tilted the bed," he once said. "After all that, they didn't tell me what I had, except that it was not multiple sclerosis, and that I was an atypical case."
Eventually, however, doctors did diagnose Hawking with the early stages of ALS. It was devastating news for him and his family, but a few events prevented him from becoming completely despondent. The first of these came while Hawking was still in the hospital. There, he shared a room with a boy suffering from leukemia. Relative to what his roommate was going through, Hawking later reflected, his situation seemed more tolerable. Not long after he was released from the hospital, Hawking had a dream that he was going to be executed. He said this dream made him realize that there were still things to do with his life.





In a sense, Hawking's disease helped him become the noted scientist he is today. Before the diagnosis, Hawking hadn't always focused on his studies. "Before my condition was diagnosed, I had been very bored with life," he said. "There had not seemed to be anything worth doing." With the sudden realization that he might not even live long enough to earn his PhD, Hawking poured himself into his work and research. 
As physical control over his body diminished (he'd be forced to use a wheelchair by 1969), the effects of his disease started to slow down. Over time, however, Hawking's ever-expanding career was accompanied by an ever-worsening physical state. By the mid-1970s, the Hawking family had taken in one of Hawking's graduate students to help manage his care and work. He could still feed himself and get out of bed, but virtually everything else required assistance. In addition, his speech had become increasingly slurred, so that only those who knew him well could understand him. In 1985 he lost his voice for good following a tracheotomy. The resulting situation required 24-hour nursing care for the acclaimed physicist.
It also put in peril Hawking's ability to do his work. The predicament caught the attention of a California computer programmer, who had developed a speaking program that could be directed by head or eye movement. The invention allowed Hawking to select words on a computer screen that were then passed through a speech synthesizer. At the time of its introduction, Hawking, who still had use of his fingers, selected his words with a handheld clicker. Today, with virtually all control of his body gone, Hawking directs the program through a cheek muscle attached to a sensor.
Through the program, and the help of assistants, Stephen Hawking has continued to write at a prolific rate. His work has included numerous scientific papers, of course, but also information for the non-scientific community.
Hawking's health, of course, remains a constant concern—a worry that was heightened in 2009 when he failed to appear at a conference in Arizona because of a chest infection. In April, Hawking, who had already announced he was retiring after 30 years from the post of Lucasian Professor of Mathematics at Cambridge, was rushed to the hospital for being what university officials described as "gravely ill." It was later announced that he was expected to make a full recovery.

Stephen Hawking’s Wife and Children

At a New Year's party in 1963, shortly before he had been diagnosed with ALS, Stephen Hawking met a young languages undergraduate named Jane Wilde. They were married in 1965. The couple gave birth to a son, Robert, in 1967, and a daughter, Lucy, in 1970. A third child, Timothy, arrived in 1979. 
In 1990, Hawking left his wife, Jane, for one of his nurses, Elaine Mason. The two were married in 1995. The marriage put a strain on Hawking's relationship with his own children, who claimed Elaine closed off their father from them. In 2003, nurses looking after Hawking reported their suspicions to police that Elaine was physically abusing her husband. Hawking denied the allegations, and the police investigation was called off. In 2006, Hawking and Elaine filed for divorce. 
In the years since, the physicist has apparently grown closer with his family. He's reconciled with Jane, who has remarried. And he’s published five science-themed novels for children with his daughter, Lucy. 

Education and Cambridge University

Early in his academic life, Hawking, while recognized as bright, was not an exceptional student. During his first year at St. Albans School, he was third from the bottom of his class. But Hawking focused on pursuits outside of school; he loved board games, and he and a few close friends created new games of their own. During his teens, Hawking, along with several friends, constructed a computer out of recycled parts for solving rudimentary mathematical equations.
Hawking entered University College at Oxford University at the age of 17. Although he expressed a desire to study mathematics, Oxford didn't offer a degree in that specialty, so Hawking gravitated toward physics and, more specifically, cosmology.
By his own account, Hawking didn't put much time into his studies. He would later calculate that he averaged about an hour a day focusing on school. And yet he didn't really have to do much more than that. In 1962, he graduated with honors in natural science and went on to attend Trinity Hall at Cambridge University for a PhD in cosmology.
In 1968, Hawking became a member of the Institute of Astronomy in Cambridge. The next few years were a fruitful time for Hawking and his research. In 1973, he published his first, highly-technical book, The Large Scale Structure of Space-Time, with G.F.R. Ellis.
In 1979, Hawking found himself back at Cambridge University, where he was named to one of teaching's most renowned posts, dating back to 1663: the Lucasian Professor of Mathematics.

Hawking and Space Travel

In 2007, at the age of 65, Hawking made an important step toward space travel. While visiting the Kennedy Space Center in Florida, he was given the opportunity to experience an environment without gravity. Over the course of two hours over the Atlantic, Hawking, a passenger on a modified Boeing 727, was freed from his wheelchair to experience bursts of weightlessness. Pictures of the freely floating physicist splashed across newspapers around the globe.
"The zero-G part was wonderful, and the high-G part was no problem. I could have gone on and on. Space, here I come!" he said.
Hawking is scheduled to fly to the edge of space as one of Sir Richard Branson's pioneer space tourists. He said in a 2007 statement, "Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers. I think the human race has no future if it doesn't go into space. I therefore want to encourage public interest in space."

TV and Film Appearances

If there is such a thing as a rock-star scientist, Stephen Hawking embodies it. His forays into popular culture have included guest appearances on The SimpsonsStar Trek: The Next Generation, a comedy spoof with comedian Jim Carrey on Late Night with Conan O'Brien, and even a recorded voice-over on the Pink Floyd song "Keep Talking." In 1992, Oscar-winning filmmaker Errol Morris released a documentary about Hawking's life, aptly titled A Brief History of Time. Other TV and movie appearances include:

Hawking was back in the headlines in the summer of 2015. In July, he held a news conference in London to announce the launch of a project called Breakthrough Listen. Funded by Russian entrepreneur Yuri Milner, Breakthrough Listen was created to devote more resources to the discovery of extraterrestrial life.

In October 2017, Cambridge University posted Hawking's 1965 doctoral thesis, "Properties of Expanding Universes," to its website. An overwhelming demand for access promptly crashed the university server, though the document still fielded a staggering 60,000 views before the end of its first day online.

The Hungry Mouse

Description: 9 Contoh Teks Story Telling Dalam Bahasa Inggris Beserta Dengan Arti LengkapA mouse was having a very thought time. She had no food for many days and made strenuous efforts get her food. All her efforts went in vain. She looked everywhere to find her food. As the days pass by, she became very thin.
One day, the mouse found a basket with corns. She also noticed a tiny hole in the basket, which was sufficient enough to move her in. She easily moved inside the hole.
Since she had no foods for many days, she ate a large amount of corn. Without realizing her, she continuously ate more and more corns. She realized very later that she ate a lot more than she actually required. After eating a whole lot of corn, she became very fat!
Satisfied with corns, the fat mouse tried to come out of the basket through the small hole. Unfortunately, the tiny hole could not accommodate the big mouse!!!!
The mouse started screaming ‘Oh god! Let me come out, how can I come out?’
A rat after hearing mouse’s screaming voice from the basket, asked her what happened!
Mouse told the story and asked rat a solution.
Rat told, ‘if you want to come out the basket, wait for sometime or even days to lose your all your fat until you grow thin.’

GIRAFFE

GIRAFFE

Range map of extant Giraffa species.
The giraffes (Giraffa camelopardalis) are an African even-toed ungulate mammal, the tallest living terrestrial animal, and the largest ruminant. They are specific name refers to its camel-like face and patches of color on a light background, which bears a vague resemblance to a leopard's spots. The giraffes are also noted for its extremely long neck and legs and prominent horns. They stand 5–6 m (16–20 ft) tall and have an average weight of 1,200 kg (2,600 lb) for males and 830 kg (1,800 lb) for females. they are classified under the family Giraffidae, along with its closest extant relative, the okapi. There are nine subspecies, which differ in size, coloration, pattern, and range.


Giraffes are the world's tallest mammals, thanks to their towering legs and long necks. A giraffe's legs alone are taller than many humans—about 6 feets. These long legs allow giraffes to run as fast as 35 miles an hour over short distances and cruise comfortably at 10 miles an hour over longer distances.

Giraffes have spots covering their entire bodies, except their underbellies, with each giraffe having a unique pattern of spots. Giraffes have long necks, which they use to browse the leaves of trees. They also have slightly elongated forelegs, about 10% longer than their hind legs. Like nearly all mammals, a giraffe has seven neck vertebrae, which are extremely elongated. These bones produce bud like horns called ossicones.

Typically, these fascinating animals roam the open grasslands in small groups of about half a dozen.
Bulls sometimes battle one another by butting their long necks and heads. Such contests aren't usually dangerous and end when one animal submits and walks away.
Giraffes use their height to good advantage and browse on leaves and buds in treetops that few other animals can reach (acacias are a favorite). Even the giraffe's tongue is long! The 21-inch tongue helps them pluck tasty morsels from branches. Giraffes eat most of the time and, like cows, regurgitate food and chew it as cud. A giraffe eats hundreds of pounds of leaves each week and must travel miles to find enough food.
The giraffe's height also helps it to keep a sharp lookout for predators across the wide expanse of the African savanna.
The giraffe's stature can be a disadvantage as well—it is difficult and dangerous for a giraffe to drink at a waterhole. To do so they must spread their legs and bend down in an awkward position that makes them vulnerable to predators like Africa's big cats. Giraffes only need to drink once every several days; they get most of their water from the luscious plants they eat.
Female giraffes give birth standing up. Their young endure a rather rude welcome into the world by falling more than 5 feet to the ground at birth. These infants can stand in half an hour and run with their mothers an incredible ten hours after birth.
The extinct giraffid Samotherium (middle) in comparison with the okapi (below) and giraffe. The anatomy of Samotheriumappears to have shown a transition to a giraffe-like neck.[13]
Giraffes have high adult survival probability, and an unusually long lifespan compared to other ruminants, up to 25 years in the wild. Because of their size, eyesight and powerful kicks, adult giraffes are usually not subject to predation, aside from lions. Giraffes are the most common prey for the big cats in Kruger National Park. Nile crocodiles can also be a threat to giraffes when they bend down to drink. Calves are much more vulnerable than adults and are additionally preyed on by leopardsspotted hyenas, and wild dogs. A quarter to a half of giraffe calves reaches adulthood. Calf survival varies according to the season of birth, with calves born during the dry season having higher survival rates. The local, seasonal presence of large herds of migratory wildebeests and zebras reduces predation pressure on giraffe calves and increases their survival probability.
Some parasites feed on giraffes. They often host for ticks, especially in the area around the genitals, which has thinner skin than other areas. Tick species that commonly feed on giraffes are those of genera HyalommaAmblyomma and Rhipicephalus. Giraffes may rely on red-billed and yellow-billed oxpeckers to clean them of ticks and alert them to danger. Giraffes host numerous species of internal parasite and are susceptible to various diseases. They were victims of the (now eradicated) viral illness rinderpest.[7] Giraffes can also suffer from a skin disorder, which comes in the form of wrinkles, lesions or raw fissures. It appears to be caused by a nematode and may be further affected by fungal infections. As much as 79% of giraffes show signs of the disease in Ruaha National Park.
Giraffes have beautiful spotted coats. While no two individuals have exactly the same pattern, giraffes from the same area appear similar.

Up until recently, the consensus has been there is only one species of giraffe with multiple subspecies. In 2016, some scientists released a study that claims genetic differences among giraffe populations indicate the existence of four distinct giraffe species.

LEADERSHIP TRAINING IN WEEKENDS
Last week, on 21-23 September (thursday until saturday activities make me lose 2 days these off to holiday), my school, 3 Senior High School Bandung in collaboration with Infantry. Purpuse infantry collaboration with my school to organize student basic leadership training. This activity is compulsory for 10th grade students(for generation 2017-2018). This activity held to improve discipline, responsibility, leadership, teamwork,and citizenship of students. In this activity, we must do everything fast, including eating and bathing.For eating we are given ten minutes and for bathing 5-8 minutes maybe . This activity was held on “Pussenif” (Pusat Kesenjataan Infanteri/ center of infantry weaponry) which located on Supratman Street, Bandung.
            On the first day, We arrived at Pussenif 6:30am. Student who bring handphone and/or watch must collect their cell phone and/or watch to box who have been prepared. After that, we held a flag ceremony beside that activity we are divided groud with absen method. After divided group, we listened mandate from the headmaster of 3 Senior High School Bandung and commander of Pussenif, Rubiono Prawiro in the convention hall. In the afternoon, we placed our bags in the barrack. On the first day, we got a lot of material about citizenship. We listened to the speaker in the convention hall until 10pm.Then many senior student gave us many lesson to more efficient.  In the afternoon, male student who has thick hair, should be cut. We went to bed on about 10:30pm.
            On the second day morning. Sudenly we are woken up by infantry on 02.00 am to make line in front of barracks and we are cheked by infantry to see compliteness of equipmen.If Someone who not complite of the equipment will get the punishment. Fortunitely I didnt get the punish ment because my equipment is complite. Then we prayed Tahajud to gether on 04.00 am we did morning gymnastic on about 5:30 am. On that day, we got a lot of material about line of march from morning to evening. In the evening, we all went to Taman Makam Pahlawan (cemetery garden of national heroes) which located on Cikutra street. We went there on foot. On there, we did “Caraka Malam”, we must enter the cemetery, with 2 or 3 friends with no light or candle. We also pray together after that. We went back to Pussenif on about 1:30am on the next day.

            On the last day, we did some outbound activity that improved stamina, power, and teamwork from morning to afternoon. In one of outbound I got punishment because I did fault in bridge made of ropes. My punishment is down to soil and say to dont do with fault again loudly. After that we watched G30S PKI film. In the afternoon. After that, we held a ceremony. We demonstrated our line up capability. After the ceremony, we got a participation certificate. We also got our cell phones and watches back. We took some photos before we went home. That was a great, impressive, and unforgettable experience I ever experienced. After this training made sudents 3 senior high school become bald.

 UNFORGETTABLE EXPERIENCE
when I was first in junior high school
 
 I want to tell you a story from when I was in 7th grade at junior high school 5 bandung and I was 13. When I got home from school at 5 pm because I have group work. I ride public transport. The public vehicle I ride is an city transport kalapa ledeng track. I go up that leads to kalapa.I got off in asia afrika. I waited for the cicaheum to cibeureum bus at 5:10. After waiting for a while the bus then arrives. 

 On the bus I sat sleeping. I got off at the eagle stop near the supermarket at about 6 o'clock. I stopped by the nephew's home to pray and eat until 6.30. After some time at home nephew I went home to my parents who reside margaasih. I ride city transport ciroyom to margaasih track. I spent time in angkot by listening to music and sleeping.

 When I have reached bumi asri I call my mother "Assalamualaikum mom can you pick up me in bumi asri" to be picked up by motorcycle . My mother replied "I can not pick you up because at home no motor because it is used by your sister". I answer "Ok I will walk to home" Answer "Ok you must be careful" at 7.30.

 At that time there was no motor at home. I am very confused because there is no city transport cimindi margaasih track. There is no City transport cimindi margaasih because it has passed at 6.00. I then walk from bumi asri to the margaasih.

 When I'm walking I suddenly there is someone rider approaching me. He offered me a ride. Then I accepted the offer. I was escorted by the rider to the highway near the house.
 Then I thank you very much. At that time I was very grateful because there are people who want to help me and I will not come home in the afternoon anymore.
