The legendary Stephen Hawking was on March 14th in heaven. He died of aging at the age of 76, suffering from a long-standing illness of amyotrophic lateral sclerosis (ALS), which had been paralyzed for decades.
Today, let's talk about this famous and inspiring British scientist, best known for his work explaining the origins of the universe and black holes.

Who was Stephen Hawking and what did he know about?
Born on January 8, 1942, Stephen Hawking was a famous British physicist who made important contributions to a variety of fields including cosmology, quantum gravity and general relativity.
Dr. Hawking is the author of several popular science books, including a brief history of 'Time', and has studied groundbreaking theorems on singularity within the framework of general relativity. He also made theoretical predictions about black holes emitting radiation.
He had a thorough understanding of the universe and knew clearly his goal of answering questions such as why the question was, why it existed, and why.
You do not have to read the famous Steven Hawking theory if you have the curiosity of being attracted to science and finding facts about the universe. But before we dig deep into his life and his discoveries and achievements, let me look at his life in general.
Stephen Hawking's IQ, Learning and Interest
Stephen Hawking's IQ was not hidden in the world. British scientists, professors and authors were bright but not outstanding students.
He always focused on learning outside school. This is well known in the example of using recycled parts to make computers that solve basic mathematical equations with friends.
He wanted to study mathematics, but unfortunately Oxford did not offer a degree in that specialization. Because of this, he chose physics and got accurate cosmology.
After graduating from Oxford, he went to Cambridge University to do more research on cosmology.
If the normal IQ level range is 85 to 115, Stephen Hawking's IQ is 160. But when he was asked the same question in an interview with the New York Times in 2004, his answer was, "I do not know. The pride about their IQ is loser."
His IQ does not need proof when his work and discovery speaks about the same thing. Let's look at them.
What is Stephen Hawking's important discovery?
- He explained that with the Oxford mathematician Roger Penrose, the Big Bang (if there had been) must have originated from a singular point, an infinitely small point.
- He studied that it emitted energy called Hawking radiation. And they tend to lose mass gradually in this process. The reason is the quantum effect that occurs in the area called the event horizon near the edge of the black hole.
- In one of Stephen Hawking's theories we can see his prediction of the existence of a mini-black hole during the Big Bang. This small black hole was so hot that it could not have been shed until it disappeared. This small black hole is believed to have been killed by a powerful explosion.
- He also investigated whether the light or particles entering the black hole in the case of evaporation had been destroyed. He initially believed that his discovery had disappeared from space, but the American physicist Leonard Susskind disagreed and this idea was called paradox of information. In 2004, Hawking was approved for information retention.
- He worked with the physicist James Hartle to describe the history of the universe through the expression of mathematics. Quantum theory, however, represents an ambiguous difference between space and time. So the need to ask what happened before the Big Bang was no longer required.
In summary, the Stephen Hawking theory has led to the following important findings:
He performed path clues to the uniqueness and applied it to the entire universe, and also said that gravity produces singularities.
- 1971 ~ 72 Black Hall Mechanic Law
Along with Brandon Carter and James Bardeen, he discovered the law of black hole mechanics.
- The first rule, also known as the Hawking area theorem, says that the entire surface area of a black hole will never be reduced.
- The second rule explains that the black hole was hot. This is a contradiction in classical physics that black holes do not emit heat.
- The third is the 'no hair' theorem of a black hole. This indicates that the black hole can be characterized by three numbers, mass, charge and angular momentum.
- The black hole emits radiation until it is depleted and eventually evaporates. This is also referred to as Hawking radiation.
- The universe inflation theory of 1982
Hawking was one of the earliest researchers to calculate quantum fluctuations, a small change in the distribution of matter. This has shown that inflation can cause galaxies to spread in space.
- 1983 Space Wave Model
One of Stephen Hawking's theories says that the concept of the beginning of the universe is meaningless because there was no time before the big bang explosion. He believed that the universe had no original boundaries in time and space.
- History of & # 39; Time & # 39; published in 1988
You can find topics such as big bang, black hole, light cone, etc which are covered in his book. The book was a success and was featured on the British Sunday Times bestseller list.
- Top-down theory on cosmology in 2006
This theory says that the universe consists of a superposition of many initial conditions rather than a unique initial state.
In addition, he has written many informative books such as The Universe in a Nutshell (2001) and God made the Integers: a mathematical breakthrough that changed history (2005).
His achievements will always be recognized by the world, but another interesting aspect that surprised the world is his survival story. The intractable disease he can diagnose actually takes two to three years to kill.
Stephen Hawking has won the odds of ALS for more than half a century.
Stephen Hawking was diagnosed with ALS, an untreatable neurological disorder. The disease leads to gradual deterioration as well as death of neurons that regulate spontaneous muscle movements such as breathing, walking, speaking and chewing.
The average life expectancy after an ALS diagnosis is about 3 years, but 20% live 5 years after diagnosis, 10% survive at 10 years, and 20% survivors may vary from person to person.
Lifespan is dependent on motor neurons (respiratory muscles) that move the diaphragm. This causes death due to respiratory failure.
The other is swallowing the muscles that lead to malnutrition and dehydration. Therefore, if the patient is not suffering from these two symptoms, he or she is more likely to live longer than expected.
For Stephen Hawking, I was surprised to see him survive for a long time. He was certainly an exception.
He finally breathed his last on March 14, 2018, but his contribution to the world will make him live forever. From Stephen Hawking's IQ theory to theory, he created a place where he could not replace himself in the world. His departure was not only a frustration for the scientific community, but a frustration for scientists related to physics and cosmology.
