The Nobel Prize in physics will be divided between two Japanese scientists and an American, the second announcement of the Royal Swedish Academy of Sciences.

Yoichiro Nambu, Makoto Kobayashi and Toshihide Maskawa made new discoveries about the basic particles that build the field.

The American of Japanese origin Yoichiro Nambu identified a mechanism called spontaneous symmetry breaking in the field of subatomic physics.

Kobayashi Maskawa managed to predict the existence of at least three families of elementary particles, known as quarks.

According to the Standard Model of particle physics, quarks are the subunits of protons and neutrons, which together form the nucleus of atoms.

The Nobel Prizes - delivered in the areas of chemistry, medicine, literature, economics and peace - are 10 million Swedish crowns (about $ 1.3 million) each. The winners also receive a medal and a diploma.

In 2007, the winners of the Nobel Prize in Physics was the Frenchman Albert Fert and German Peter Gruenberg for work in the discovery of a technology used in the reading of hard disks in computers, allowing the industry to develop technology tools sensitive to read, to get data on hard drives, iPods and other devices.

The Nobel Prize for Medicine this year was also given to the French Francoise Barre-Sinoussi and Luc Montagnior, for having identified the virus responsible for AIDS, and the German Harald zur Hausen, for having discovered the association between HPV virus and cervical cancer.
