Biography of Antoine Henry Becquerel (1852-1908)
Antoine Henri Becquerel was born in 1852 to an educated family in France.
Antoine Henri Becquerel, a French physicist, is one of the discoverers of the phenomenon of radioactivity.
His father and grandfather, like him, studied physics and became professors in the same field.
Antoine Henri Becquerel studied at the Paris Polytechnic from 1872 to 1874 and at the School of Stairs and Roads from 1874 to 1877. From 1878 he worked as an associate professor at the Polytechnic and at the Ministry of Roads and Bridges as a senior engineer.
In 1884, Becquerel proved the infrared bands in the spectrum of sunlight. He became a member of the Academy of Sciences in 1889 and in 1891 became a professor of applied physics at the Natural History Museum in Paris.
It was in that year that he began work on the phenomenon of phosphorescence in hot The phenomenon of radioactivity minerals. The discovery of X-rays or Roentgen by Wilhelm Konrad Roentgen in 1895 drew Beckrel’s attention to the phenomenon of fluorescence.
Phosphorescence and fluorescence are phenomena in which certain substances store energy after being exposed to visible or invisible light or other factors such as shock or heat, and then emit it as a spectrum of visible waves.
The difference between these two phenomena is in the time between receiving and radiation, or in other words, in the durability of radiation. If the excitation time is less than one second, we call the phenomenon fluorescence, and if it is more than that, we call it phosphorescence.
In one of his studies, Becquerel, who worked on the phenomenon of fluorescence, placed some uranium-containing material on black paper beneath a sensitive photographic screen and exposed it to sunlight.
Becquerel believed that sunlight could not pass through black paper, but if X-rays were present in the fluorescence produced by the material, it could affect the photographic screen. After stopping his work, he placed photographic plates containing some uranium in his desk drawer. A few days later, when he decided to display the photos, he noticed that the screen was blackened by a very strong ray. Further research by Beckler in this area led to the discovery of radioactive elements.
Becquerel informed the Academy of Sciences of his discovery on February 24 of that year.
He was awarded the Nobel Prize in Physics for his discovery of this spontaneous radiation, called radioactivity by Marie Curie, along with Pierre and Marie Curie of France.
Becquerel was awarded the Nobel Prize in Physics in 1903 for his discovery of spontaneous radiation and other services, along with Marie and Pierre Curie. The unit for measuring radioactivity is named after him.
Antoine Henri Becquerel died on August 25, 1908, in Le Croisic, on the shores of the Bay of Biscay.
Meet the Nobel laureates who changed the world
Planet Earth is full of billions of people who are all working, thinking, playing and finding the right path out of all the confusing paths; Despite this turmoil, some people have not lost their focus and are discovering very new ways of dealing with life, the universe, and the concept of existence, and some of these people are Nobel Prize winners.
Nobel Prizes are not prizes awarded to anyone under any circumstances. Founded in 1895 by Swedish inventor and human rights activist Alfred Nobel, the award recognizes and recognizes advances in science and culture, literature, peace, economics, chemistry, physics and medicine.
The winners will receive a gold medal, a diploma and a cash prize, which has increased to more than $ 1 million in recent Nobel ceremonies. All of these awards should go to individuals except the Nobel Peace Prize, which can also be awarded to organizations. Prizes are sometimes awarded to several people, but by law these people should not exceed three.
Since 1901, when the first Nobel Prize was awarded, 549 Nobel Prizes have been awarded The phenomenon of radioactivity to 853 individuals or organizations, with more than one Nobel Prize. The Nobel Prize is awarded annually, but the prize will not be awarded to anyone who has not done so during the year in which he or she is eligible to receive the prize.
The Nobel Prizes are very valuable, but even more valuable are the works that led to the Nobel Prize. Nobel laureates are thinkers who have dedicated their lives to revealing the secrets of human life, they have helped to promote human collective intelligence, and a number of them have transformed human life through their studies:
This Franco-Polish scientist was a selfless and silent woman who was at the same time a brilliant scientist whose studies not only changed the way scientists viewed the world, but for many years she was known as a different cultural symbol.
Cory was born in 1867 and spent most of his career studying the principles and rules of radioactivity. In 1903, he and his wife Pierre and Henry Beckworth received the Nobel Prize in Physics for their study of physics. Marie Curie also won the Nobel Prize in Chemistry in 1911 for her discovery of radium and polonium, becoming one of the few people to have received the Nobel Prize in two different disciplines.
During World War I, he used his knowledge of radiation to build portable X-ray machines for battlefields. He often took control of the machine and trained other women to help doctors find bullets in the injured.
From a physical point of view, Einstein helped to reconsider the world and the whole universe. Einstein earned a degree in chemistry and mathematics after graduation, and when he could not find a job, he went to work in the Swiss Patent Office. It was there that, in times of idleness, his busy mind posed great questions in theoretical physics. He discovered mass-energy equality and proposed the theory of relativity.
In 1921, he was awarded the Nobel Prize in Physics for his discovery of the photoelectric effect, a phenomenon in which the electrons of a substance explode under the influence of light. According to him, light was made of particles, and this discovery led to the invention of photoelectric cells and eventually to television, cinema, and many great discoveries. Perhaps the most important part of his research was the part that developed human understanding of quantum theory.
International Committee of the Red Cross
In a world torn apart by war, the Red Cross played a key role in healing the wounds of many. The The phenomenon of radioactivity organization was awarded the Nobel Peace Prize in 1917, 1944 and 1963 for its humanitarian services. The Red Cross was founded in 1863 in Geneva, Switzerland, to help the wounded and sick during the war, regardless of ethnicity or nationality. The committee is not only helping the military, it is also trying to help civilians who have been involved in the war.
During World Wars, the Red Cross monitored compliance with the Geneva Convention and documented any violations of the Convention. Volunteers also visited prisoners in war camps to ensure that they were treated humanely, while also paving the way for the exchange of prisoners.
The Red Cross also played an important role in maintaining verbal The phenomenon of radioactivity communication between soldiers and their families during wars, and generally proved that the good side of humanity could be maintained through bullets and bombings.
