Inspiring Person

Assalamualaikum wr.wb .
Hello ! Nice to meet you again, friends.

Now, I will tell you about my inspiring person.
My inspiring person is Stephen Hawking. Do you know who is Stephen Hawking?
I think, everyone in this world know about him.
So, I will tell you about Stephen Hawking more than that.
This is Stephen Hawking.

So, who is Stephen Hawking?
   Stephen Hawking 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. He was born in Oxford, England on January 8, 1942. His scientific works include a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity and theoretical prediction that black holes emit radiation, often called Hawking radiation. Hawking was the first to set out a theory of cosmology by union of the general theory of relativity and quantum mechanics. He is a vigorous supporter of the many-worlds interpretation of quantum mechanics.
   


He grew up in a highly educated family. Both of his parents had attended Oxford University and his father, Frank, was a medical researcher. his mother was one of the first female students who graduated from the Oxford. Hawking was born when his family as well as the whole nation was going through a financial crunch because of the ongoing World War II. He was the eldest out of the four children. His father became the head of the Division of Parasitology at the National Institute of Medical Research and went to Africa for research - he aspired for him to become a doctor but Hawking showed more interest in astronomy. 


Hawking began his schooling at the Byron House School in Highgate, London. He later blamed its "progressive methods" for his failure to learn to read while at the school.In St Albans, the eight-year-old Hawking attended St Albans High School for Girls for a few months. At that time, younger boys could attend one of the houses.He attended St Albans School but he was never a conventionally brilliant student, rather he was more interested in what happened outside the classroom, and spent his time and energy in inventing new things.Although known at school as "Einstein", Hawking was not initially successful academically. With time, he began to show considerable aptitude for scientific subjects and, inspired by Tahta, decided to read mathematics at university. As it was not possible to read mathematics there at the time, Hawking decided to study physics and chemistry. Despite his headmaster's advice to wait until the next year, Hawking was awarded a scholarship after taking the examinations in March 1959.


Hawking began his university education at University College, Oxford in October 1959 at the age of 17. He developed into a popular, lively and witty college member, interested in classical music and science fiction. Part of the transformation resulted from his decision to join the college boat club. In 1962, he graduated with honors, and went on to attend the University of Cambridge for a Ph.D. in cosmology.


During his first year, Hawking started to show abnormal physical symptoms; he would suddenly trip and fall or his speech slurred. He suppressed these symptoms but when his father noticed them, he was sent for a series of tests.
It was diagnosed that he was in the early stages of Amyotrophic Lateral Sclerosis, which meant that the part of his nervous system that was responsible for muscle control was shutting down—a life threatening condition. 

When Hawking was a graduate student at Cambridge, his relationship with Jane Wilde, a friend of his sister whom he had met shortly before his diagnosis with motor neurone disease, continued to develop. The couple became engaged in October 1964. Hawking later said that the engagement gave him "something to live for" and the two were married on 14 July 1965.  He divorce from Jane in 1995, Hawking married Mason in September. In 2006, Hawking and Mason quietly divorced,[244][245] and Hawking resumed closer relationships with Jane, his children, and his grandchildren. 

From his diagnosis, he can't talk. Stephen Hawking talks through the computer using a speech-generating device (SGD) or a voice output communication aid. This is a special device that either supplements or replaces speech/writing.
You can watch this video, if you want to more know about that machine. 

With this new found realization of the suddenness of death and the fact that according to the doctors he only had another two years to live, Hawking started concentrating fully on his research work.
His research is about the prevailing theories of the creation of the universe: the Big Bang and Steady State theories. His thesis was approved in 1966. Hawking received a research fellowship at Gonville and Caius College he obtained his PhD degree in applied mathematics and theoretical physics, specialising in general relativity and cosmology, in March 1966 and his essay titled "Singularities and the Geometry of Space-Time" shared top honors with one by Penrose to win that year's prestigious Adams Prize.  


About his career that greatly contributes to the world
1966–1975
      In his work, and in collaboration with Penrose, Hawking extended the singularity theorem         concepts first explored in his doctoral thesis. This included not only the existence of singularities but also the theory that the universe might have started as a singularity.In 1970 they published a proof that if the universe obeys the general theory of relativity and fits any of the models of physical cosmology developed by Alexander Friedmann, then it must have begun as a singularity.
        In 1970, Hawking postulated what became known as the second law of black hole dynamics, that the event horizon of a black hole can never get smaller.His essay titled "Black Holes" won the Gravity Research Foundation Award in January 1971. Hawking's first book, The Large Scale Structure of Space-Time, written with George Ellis, was published in 1973. 
    Beginning in 1973, Hawking moved into the study of quantum gravity and quantum mechanics.work showed that according to the uncertainty principle, rotating black holes emit particles. His results, which Hawking presented from 1974, showed that black holes emit radiation, known today as Hawking radiation.

1975-1990
   Hawking returned to Cambridge in 1975 to a more academically senior post, as reader in gravitational physics. He was appointed a professor with a chair in gravitational physics in 1977. Hawking also began a new line of quantum theory research into the origin of the universe. In 1981 at a Vatican conference, he presented work suggesting that there might be no boundary – or beginning or ending – to the universe. 
   He subsequently developed the research in collaboration with Jim Hartle, and in 1983 they published a model, known as the Hartle–Hawking state. In his early work, Hawking spoke of God in a metaphorical sense. In A Brief History of Time he wrote: "If we discover a complete theory, it would be the ultimate triumph of human reason – for then we should know the mind of God." In the same book he suggested that the existence of God was not necessary to explain the origin of the universe. 

1990-2000
     Hawking outside, in his wheelchair, talking to David Gross and Edward Witten Hawking with string theorists David Gross and Edward Witten at the 2001 Strings Conference, TIFR, India. Hawking pursued his work in physics: in 1993 he co-edited a book on Euclidean quantum gravity with Gary Gibbons. 
      Hawking has also maintained his public profile, including bringing science to a wider audience. A popular-level collection of essays, interviews, and talks titled Black Hawes and Baby Universes and Other Essays was published in 1993, and a six-part series of television series Stephen Hawking's Universe and a companion book appeared in 1997. As Hawking insisted , this time the focus was entirely on science. 

2000-present
      Hawking continued his writings for a popular audience. From 2006 on Hawking developed a theory of "top-down cosmology", which says that the universe had not one unique initial state but many different ones, and therefore that it is inappropriate to formulate a theory that predicts the universe's current configuration from one particular initial state. Top-down cosmology posits that the present "selects" the past from a superposition of many possible histories. In doing so, the theory suggests a possible resolution of the fine-tuning question.
   
In the 2005 paper he published on the subject, he argued that the information paradox was explained by examining all the alternative histories of universes, with the information loss in those with black holes being cancelled out by those without such loss. In January 2014 he called the alleged loss of information in black holes his "biggest blunder". 
    In 2007, Hawking and his daughter Lucy published George's Secret Key to the Universe, a children's book designed to explain theoretical physics in an accessible fashion and featuring characters similar to those in the Hawking family. 
       During his career, Hawking has supervised 39 successful PhD students. On 20 July 2015, Hawking helped launch Breakthrough Initiatives, an effort to search for extraterrestrial life. In August 2015, Hawking said that not all information is lost when something enters a black hole and there might be a possibility to retrieve information from a black hole according to his theory. In July 2017, Hawking was awarded an Honorary Doctorate from Imperial College London.


Why he is very special for me?
   
  Stephen Hawking is guy who never give up. Prof. Hawking is suffering from Motor neuron disease. ALS is a condition in which a person body parts get paralyzed with time & a person can survive max  6 – 7 years. But Mr Hawkings with his strong will power is living with this from last 48 years. He has been in a wheelchair for almost 42 years with almost every body part paralyses except his sharp mind can can’t even speak for 28 years. He embodies the importance of taking obstacles in one’s stride.
  This disease & condition actually changed his outlook towards life. He discovered his disease at tender age of 20’s which shattered him for some time, but then he decided not to give up & do his best till he live. Professor Stephen Hawking may be in a wheelchair, and may have to speak through a synthesizer, but he has nonetheless overcome an obstacle doctors never thought he would – to live for 48 years with ALS. Not only has Hawking overcome a monumental obstacle; he has done so exceptionally, becoming a role model.
   Working till now with his full paralysis body thru his brain, eye moment & his Voice Text speech synthesiser & small computer fixed on his wheelchair . He is continually giving his best to the fields of cosmology and quantum gravity, especially black holes, theorem of general relativity, etc. He lives life at its best even in the worst condition he is facing. He wants to enjoy weightless condition so he took the weightless flight in 2007 which was actually a big achievement in his condition.  His wish is to go to space & I wish that his dream will come true.
   
   Why I’m telling you his story? It’s because I somewhere realized maybe most of us are blessed with healthy body & mind conditions still we treat us as disable.  Sometimes we become soo helpless & give-up in front of the challenges we face in our personal, social or professional lives. We break down & give up on small things which are actually just pretty small in front of the Purpose we carry for our life.  I’m sharing this because I want you to think about this man courage, outlook & will power whenever you feel like giving up.
   So be positive, be inspirational & no matter who you are, what you are, how much capable or incapable you think you are; Just get up, wipe your tears, throw your pains & feeling of helplessness and work towards something you really good at. Be the change you want to see. 
Get up! Do something for yourself & humankind. Be an example, an inspiration that gives hope to many!
     Hope you also get motivated by Prof. Stephen Hawking like me.

In the end, I just want to share Prof. Stephen Hawking Quote:




So, See you guys!
