China's most wealthy zep countries like to study what
Gems can shine, it is a fairy tale. In fact, the stone emitted radiation (Ray), is a rare physical phenomenon. In physics, radiation (also called radiation) is a very small flow beam, has a strong penetration, such as X-rays, α-rays, β rays.
Historically, people are faced with stone (natural minerals) are often in a daze, caught in illusion. Some antique domestic players, like polished stone "in the hands of Toys" (so-called "play"), in fact, silly. March 1, 1896, the French physicist Henri - Becquerel zep (Hen ri Becquerel (1852 年 至 1908) found enriched uranium ore has a natural radioactive elements, but at that time he did not know the health hazards of radioactivity , causing him to 56 years passed away, which shows that the dead will engage in scientific research, the need for devotion.
Henry - Becquerel (now called "Ph.D.") has a female doctoral student named Marie - Curie (Marie Curie, 1867 年 至 1934), Polish-born French national, has excellent mathematics, physics talent in women rare. On the basis of the work of the instructors at the beginning of the last century, curie of natural radioactivity in more in-depth analysis and research, laid the theoretical foundation of physical radioactivity, invented the radioactive isotope separation techniques and the discovery of two new elements polonium ( Po) and radium (Ra). Under her guidance, the first time the radioisotopes used in the treatment of human cancers.
Curie credit and honor there? In fact, the Curie won two Nobel Prize (once Prize in Physics, Chemistry Prize once). In addition, there are a variety of her honor: members 56, president of the two, academicians 19, a dean, Dr. 20, a professor, an honorary citizen of 3; Also get bonus 10 medal 16. In this regard, the great physicist Albert Einstein commented:. "In all the famous people, the Marie Curie was the only man for the honor of the corrosion."
