 Who was Stephen Hawking?  Stephen Hawking Disease.

Stephen Hawking is one of the famous scientists of the 21st century whose work on physics was revolutionary in science. He worked on black holes and dispelled the misconception that black holes cannot die. Black holes are actually spinning spheres in space that swallow up everything, even time.

 He told us that when two black holes collide, the area of ​​the newly formed black hole is greater than theirs. Is.

Stephen Hawking was born in 1942 in a family that was well educated and respected. Both his father and mother were educated at Oxford University and were well known in their professions.

 His father was a researcher in the field of biology and also advised Stephen Hawking to pursue medical education, but his inclination was towards physics and mathematics. While his mother was a political activist.

Stephen Hawking Education

During his primary education, Stephen Hawking was an average student. It is said that he was so incompetent in studies that he became the third lowest student in the class. But it did not mean that he was incompetent, it meant that he was not so interested in formal education.

 His interest in science grew when he received a scholarship in natural science. He attended Oxford University where he graduated with a bachelor's degree in physics with good grades. After graduating, Hawking went on to pursue a PhD at the University of Cambridge.

During his PhD at Cambridge, Hawking had some health problems that Hawking could not talk about clearly. He sometimes fell to the ground for no reason. So he was brought to the hospital for evaluation, but lost consciousness when he was told that he had amyotrophic lateral sclerosis (ALS), a disease that would destroy all the nerves in his body. The doctors told him that he would not be able to live for more than two years, but nature had something else in mind. Then the world saw that he lived for the remaining fifty-five years.

Although he survived for such a long time despite such a severe disease, his whole body was paralyzed. He only had an extraordinary mind attached to a scientific wheelchair and with its help he could carry out his dissertation and scientific research. He used to write because this disease had weakened him so much that neither he could move any part of his body nor could he speak, but he used to type on the computer with a slight movement of his lips.

Stephen Hawking is one of those scientists who faced very difficult times during his life, but still made revolutionary discoveries. Here are some of the important are.

Hawking Radiation:

Stephen Hawking was very interested in exploring the universe and understanding its workings. He spent most of his time researching space-time and wrote many research papers on it. He also researched black holes and developed equations that show that black holes also emit some radiation, called Hawking radiation, which reduces the energy of the black holes. Prior to this idea, scientists believed that no matter or radiation could escape the immense attraction of black holes. Due to the emission of Hawking radiation, black holes can shrink and disappear.

A brief history of time:

Stephen Hawking wrote many books in his life, and one of the most famous books he wrote is "A Brief History of Time". This book became so popular that it sold millions of copies within a few years. . Hawking has written this book in such a way that an average person can easily understand it. The book covers many subjects, some of them being the big bang, space and time, forces of nature and black holes.

Despite doctors' predictions, Stephen Hawking lived a full life but with the help of modern science. His ailments worsened over time and he was unable to speak or move his body parts. With such harsh conditions, Hawking still gave lectures and worked on exploring the universe. Stephen Hawking was 76 years old when he died on March 14, 2018 at the age of 76 due to motor neurone disease (ALS).

Motivation:

Moreover, it took Stephen Hawking more than 40 hours to prepare a 45-minute lecture due to the severity of his illness. Stephen Hawking first remarried after divorcing his first wife.

After receiving training from NASA, he traveled to space and experienced zero gravity.
