March 27, 1845 - Birth of Wilhem Conrad Röntgen, discoverer of X-rays

Wilhem Conrad Röntgen (a veces escrito Roentgen) recibió, en 1901, el primer Premio Nobel de Física por el descubrimiento de los rayos X (también denominados rayos Röntgen), que realizó el 8 de noviembre de 1895. Fue consciente de este descubrimiento cuando radiografió, de manera accidental, la mano de su mujer en la que se veían los huesos y el anillo.Read more

Antoine Henri Becquerel

Antoine Henri Becquerel was a French physicist who discovered natural radioactivity and was awarded the 1903 Nobel Prize in Physics, shared with Pierre Curie and Marie Curie. He found that beta radiation is composed of electrons and that radium could be used to destroy tumors, the origin of radiotherapy.Read more

Marie and Pierre Curie

Marie and Pierre Curie jointly initiated the study of radioactivity in 1896, the main fruit of which was the discovery of the existence of two new elements in 1898: radium (atomic number 88 in the periodic table), highly radioactive, and polonium (atomic number 84), named in memory of Marie's homeland.

Ernest Rutherford, considered one of the fathers of atomic physics

Ernest Rutherford is considered one of the fathers of this discipline. He also investigated the detection of electromagnetic radiation and the ionization of the air produced by X-rays. He studied the radioactive emissions discovered by H. Becquerel, and managed to classify them into alpha, beta and gamma rays.Read more

Albert Einstein Biography

Albert Einstein was a world-renowned theoretical physicist whose work on the theory of relativity and the concept of mass-energy equivalence revolutionized scientific thought. He also made important contributions to the development of quantum mechanics and statistical mechanics. Einstein was awarded the Nobel Prize in Physics in 1921.Read more

September 29, 1901 – Birth of Enrico Fermi, the Nobel laureate who achieved the first nuclear chain reaction

Enrico Fermi was an Italian physicist known for the development of the first nuclear reactor and his contributions to the development of quantum theory, nuclear and particle physics, and statistical mechanics. In 1938, he received the Nobel Prize in Physics for his work on induced radioactivity and is considered one of the most outstanding scientists of the 20th century.Read more

Irène and Frèderic Joliot Curie: Radioactivity à la carte

A couple of French physicists who won the Nobel Prize in Chemistry in 1935 for their method of obtaining radioactive isotopes of elements that are not originally radioactive, such as nitrogen, phosphorus and aluminum. This discovery revealed the possibility of using artificially produced radioactive elements in the monitoring of chemical changes occurring in physiological processes.Read more

Frederick Soddy, Nobel Prize for his contribution to the knowledge of radioactive substances and radioactivity

Frederick Soddy received the Nobel Prize in Chemistry in 1921 for his contributions to the knowledge of radioactive substances. He demonstrated that radioactive elements can have more than one atomic weight, despite having identical chemical properties; this led to the concept of isotopes. He also showed that non-radioactive chemical elements can have multiple isotopes and that an atom can move down two places in its atomic weight by emitting alpha rays and up one by emitting beta rays. These investigations led to the discovery of the radioactive element called protactinium.Read more
