Nobel's related knowledge
Nobel is a Swedish chemist, engineer and inventor. He was born in Stockholm, Sweden on 1833. His father, an inventor, invented a new type of glycerol explosive.
Nobel became interested in chemistry and engineering when he was young, and began to engage in research. In the course of research, he discovered a new type of explosive-nitroglycerin, and used it in military and industrial fields. He also invented safety devices such as detonators and safety explosives, which provided a guarantee for the safe production of explosives.
Nobel devoted his life to scientific research and technological innovation, and his inventions and contributions were widely used in various fields. He not only made outstanding contributions in the field of explosives, but also made important achievements in other fields, such as oil exploration, mechanical engineering and medicine.
Nobel is most famous for founding the Nobel Prize, which is an international award to commend individuals or organizations that have made outstanding contributions to mankind. Nobel prizes, including physics, chemistry, medicine, literature and peace, are awarded once a year. Since 190 1 was first issued, it has become one of the most prestigious scientific and cultural awards in the world.
After Nobel's death, his legacy was used to set up the Nobel Prize Fund to support the continuous award. Today, the Nobel Prize has become one of the highest honors in the world, attracting the attention and participation of scientists, writers, politicians and others from all over the world.
