7. The Nobel Prize in Physics was established in June 19 according to Nobel's will and belongs to one of the Nobel Prizes. The Nobel Prize was founded with part of the legacy of alfred bernhard nobel, a famous Swedish chemist and inventor of nitroglycerin explosives. The Nobel Prize includes gold medals, certificates and bonus checks. In his will, he proposed to use part of his legacy ($9.2 million) as a fund, and divide the interest into five kinds of prizes: physics, chemistry, physiology or medicine, literature and peace (later added the' economic' prize), and award them to scholars who have made great contributions to mankind in these fields all over the world.
