Masters of the Universe Stephen William Hawking

           Masters of the Universe Stephen William Hawking 

Stephen William Hawking, who sits in a special wheel chair and solves distant puzzles by sitting on an unseen special wheelchair in the world of moon stars, is no longer among us.  Born on the exact 300th death anniversary (8 January) of Galileo in 1942 and Albert Einstein's birth date on 14 March at the age of 76, Hocking is now seen as just his work and such a celebrity  It will be remembered who despite all the helplessness of his mind actively discovered such things which gave him the status of super genius celebrity.  Stephen the great physicist, the great physicist and British scientist Stephen Hawking, had proved that Jeetuji could do a lot on the strength of his will, even if his body does not support him.  The result of this was that he faced many challenges in his life, including the ice bucket challenge, in which the ice-filled bucket made science progress on his body.

The need for contact with aliens and settling on another planet, Stephen Hawking feared that by the end of the year 2100, the human species would face difficulties on Earth that would make it impossible to live on this planet.  In such a situation, it would be good to go to the nearest planet to settle human settlements.  Changes in their opinion at home indicate that in the coming years, the life of Barsa Kasath Isan is going to be difficult here.

.  Hawking believed that after the next 50 years, the temperature of the Earth would increase so much that it would become difficult to live here.  By the year 2100, it will be difficult to save agriculture.  Water will start disappearing from our Earth.  Not only this, nuclear war or meteorite splashes can also adversely affect the life of the Earth, with weather changes in the future.  In such a situation, to maintain human life, one has to walk on alternate paths.  For this, human settlements on a nearby planet or satellite


For which Hawking came in 1974 with the theory of Hawking Black Holes:

 It was later known as Hawking Radiation.  Hawking spoke about the leaked energy of black holes.  Professor Hawking brought the Theory of Cosmology for the first time.  It is also called the Union of Relativity and Quantum Mechanics.  In 1988, his book A Brief History of Time on the mysteries of the universe was published.  It sold more than 10 million copies.  The Grand Design, Universe in a Nutshell, My Brief History, and The Theory of Everything are his other important books.


From illness to life, Stephen Hawking's parents were also counted among the British people.  Her mother, Ijabel Hawking, was of Scottish descent, and she studied at Oxford in the year 1930, when girls' reading and writing were not considered good there either.  His father, Frank Hawking, was a medical researcher.  The Hawking family, who lived in North London, moved from London to Oxford during the Second World War in 1942 so that Stephen Hawking was not born into a problem.  It was in Oxford itself that her sister Mary was born in 1943 and Philippa in 1947.  The Hawking family moved a few years later to live in St.Relven, at which time Stephen was eight years old.  Although, as a child, Stephen was more interested in opening home clocks and radios and assembling them back than studying, he often failed in that too.  Although these things made it difficult for him to consider a class as a student, due to these antics, classmates and teachers in the class started calling him Einstein.  At the age of sixteen, he made such a computer with the tools (parts) recycled with friends.

A computer was also created that solved mathematical equations.  From here, his life started changing direction.  Father Frank wanted to send Stephen to Oxford University, but was unable to do so due to financial constraints.  In such a situation, Stephen sat in the university examination for scholarship and got the full number in physics and secured his seat in university through scholarship.  There too, Stephen made physics (physics) the basic subject of his studies, although his father wanted Stephen to study in medical.  In Physics too, he moved away from sheepishly and chose cosmology, which was less popular then.  But before his studies at the university reached a stage, Stephen started showing signs of a rare disease.  In the first year of college, he had a problem with vertigo and stuttering.  On Stephen's 21st birthday, it was clear that he had amyotrophic lateral sclerosis (ALS), a rare form of the disease affecting motor neurons.  After two weeks of tests, doctors told them that due to this disease, they will probably be able to live for two to five years more.  Stephen's illness. For five years, Stephen had told about the early days of the disease, that one night in the hospital, he dreamed that he was being murdered.  Because of this dream, he realized that he had a lot to do in his life.  Three years later, after taking an Honors degree in Science from Oxford, Stephen moved to Cambridge University, where new discoveries were being made in the direction of space science.

Life with the support of the machine, although this round was quite difficult for Hawking :

  In the beginning, he could eat by himself, get up from bed.  Could sit, but with time, his condition started deteriorating, and it became clear that he would now have to spend his entire life in a wheelchair.  Their problem 1985. It was pouring.  He did not hesitate to go to the high sky to experience weightlessness.  Challenge choice Stephen, at the age of 65, when he arrived at the Kennedy Space Center in Florida, USA, in 2007, gave him a chance to swim for nearly two hours in a gravity-free (weightless) environment over the Atlantic in a special Boeing 727.  In this way, his dream of swimming in space was fulfilled.  Pictures of him floating around without a wheelchair were seen around the world, and he took inspiration from them. 
Hawking had also enrolled himself in the Pioneer Space Tourism Project for a tour of space, but regretted that his dream could not be fulfilled.
Just after taking the name of Stephen Hawking, the face of such a person, who is helpless in his body, appears before his eyes.  He can neither speak nor move.  To protect oneself during a crisis, one has to work very hard to see the front properly.  But when we talk about Hawking, all these weaknesses become like strengths.  Some people used to joke about Hawking that if a rare disease did not catch him, he might not be able to concentrate his mind so much, or his mind would be so absorbed, and thus he would not be able to give his invaluable contribution to science.  But it is so clear that he changed his helplessness in quality, and such that he was considered the greatest and most famous scientist after Istine.  The disease is said to have inspired him, and he began to solve mathematical questions geometrically and graphically in his brain, not on the blackboard, not one, not two, but not three.  By dimension.  This was the reason that Stephen Hawking, who conducted his successful experiments on Astro-Physics, especially the universe understandable to the common man, came to be called the Master of the Universe.

 Such as in radio broadcasting, Doordarshan, mobile phones, and drug treatment, Electromagnetic radiation plays a crucial role in our daily lives, providing both significant advantages and potential drawbacks. Research and innovation heavily rely on this form of energy. However, it is essential to be aware that excessive and uncontrolled use can have harmful consequences. 

Electromagnetic radiation is generated and emitted by charged particles, traveling through space as waves. Radio frequency (RF), specifically, refers to oscillation speeds between 30 kHz and 300 kHz. Antennas are employed to capture radio signals, allowing the reception of multiple signals simultaneously. To tune into a specific frequency, a radio tuner is necessary, often utilizing a resonator to maintain oscillations within the desired frequency range.

The electric current oscillating at radio frequencies possesses unique properties that can ionize certain materials. This specific frequency is instrumental in achieving high-frequency capabilities. The term “radio frequency TANSSA” pertains to periodic radiation associated with this phenomenon.

The relationship between radio and frequencies is fundamental to various broadcasting techniques. In developed nations, the radio spectrum is regulated by the government or allocated to specific entities for use in telecommunications and broadcasting, such as mobile networks and television stations like Doordarshan. 

When electromagnetic radiation exceeds 300 GHz, it creates interference in the Earth's atmosphere, becoming undetectable until it falls within the infrared or light frequency ranges.

Radio frequency energy comes from various sources that power our everyday electrical and electronic devices, including mobile phones, microwave ovens, electric shavers, and communication towers. This energy consists of invisible electromagnetic radiation (EMR) and is categorized into low-level, medium-level, and high-level frequencies.

Low-level frequencies start below 3 Hz and can go up to 300-3000 GHz, with wavelengths ranging from 1mm to 100mm. These frequencies are utilized in both natural and artificial electromagnetic waves, serving applications such as navigation and long-wave transmission.

Medium frequencies range from 50.0 to 3000 KHz, covering distances up to 100m, and are primarily used in radio broadcasting. High frequencies, spanning from 3 MHz to 30-3000 GHz, have wavelengths in air from 1mm to 100ฮผm, and find applications in microwave ovens, wireless technology, and advanced radar satellites.

Electromagnetic power plays a significant role in our communications, particularly since the last century. Applications include radio broadcasting, television (Doordarshan), mobile phone technology, and even medical treatments, like surgeries that can be performed without blood transfusions. Microwave ovens have become essential in our kitchens, while remote controls and FM radio are popular examples of how high-frequency electromagnetic waves are used in daily life.

Although the advancements in technology have positively impacted our lives, they also come with harmful effects. The use of radio frequencies transmitted by remote controls and other devices can adversely affect humans, vegetation, and animals. Mobile phone towers, often situated in various locations, emit radiation that is altering human health and behavior. Research has definitively linked radio frequency exposure to various types of cancer. Notably, studies indicate that children, particularly those in early adolescence, are more susceptible to the effects of radio frequencies compared to adults. 

The radiation from mobile phones can affect the developing brains of children, as their heads are smaller and more vulnerable. This can lead to changes in brain composition and may interfere with developing brain waves, increasing the risk of genetic issues. Additionally, children's skulls are not as strong as those of adults, making them more susceptible to the potential dangers of radiation exposure..

The excessive use of mobile phones is believed to have harmful effects on fetuses. Alarmingly, the population of small sparrows is declining, which some attribute to radio frequency radiation. These once-vibrant birds that would chirp throughout the day are now facing issues related to fertility, raising concerns about their potential extinction if this trend continues. 

Similarly, small insects like bees are also suffering from the consequences of radio frequency exposure. Their fertility has been compromised, and they exhibit disorientation, impairing their natural behaviors and routines. 

Furthermore, it's worrying that many young children are using mobile phones without restraint. Health experts caution against this practice, particularly for children under the age of sixteen, urging a reduction in exposure to radio frequency radiation. It's important to recognize that cellular towers are major sources of this radiation, which poses significant health risks.

Nowadays, many young children are using mobile phones without much caution, but health professionals have cautioned that children under sixteen should avoid cell phone use to protect themselves from the effects of radio frequency radiation. Cellular towers emit radiation that can be extremely harmful. Recent studies indicate that radio frequency radiation can disrupt normal biological cell functions. The World Health Organization has even raised concerns about the potential cancer risks associated with this type of radiation. Additionally, exposure to radio radiation may contribute to birth defects, depression, Alzheimer's disease, memory issues, and fatigue.

Some electrical engineers, doctors, and environmental experts have conducted independent studies that indicate certain spots on the upper surface of green coconuts are affected by radio frequency radiation, while healthy coconuts show no such signs. Similarly, medicinal plants appear to be losing their beneficial properties. Additionally, areas with cell phone towers are experiencing an increase in unusual lightning activity, and some vegetables, like tomatoes, are developing disorders. This raises concerns that cell phones and towers impact our lives negatively.

In today's world, many essential functions, including medical diagnostics and communication systems, rely on radio frequency radiation. For instance, Doordarshan requires radio for operation, and aircraft cannot function without radar. Nonetheless, it's important to acknowledge the potential side effects associated with these modern technologies. We should use them responsibly rather than indiscriminately.

In developed countries, steps are being taken to mitigate these issues, such as banning mobile use for individuals under sixteen and issuing warnings in the USA, Europe, and Australia to reduce usage. However, similar measures are lacking in regions like India, Pakistan, Bangladesh, and Africa. Without proper control, we risk the extinction of certain species, which will subsequently impact human life. Therefore, we must embrace modern facilities with caution to ensure our health and longevity.
