Ida Noddack, born 25 Feb 1896, was a German chemist who, working with her future husband Walter Noddack, co-discovered (1925) element 75, rhenium. They found trace amounts in the mineral columbite. Some years later, she commented on the possibility of fission upon hearing the reports of Fermi's 1934 observations of the neutron bombardment of uranium. From what was the element rhenium named? | |

Glenn T. Seaborg (1912-1999) was an American nuclear chemist. During 1940-58, Seaborg and his colleagues at the University of California, Berkeley, produced nine of the transuranic elements (plutonium to nobelium) by bombarding uranium and other elements with nuclei in a cyclotron. He coined a name for the elements in this series. What name did Seaborg give this series of elements? | |
Louis Carl Heinrich Friedrich Paschen (1865-1947) was a German physicist who was an outstanding experimental spectroscopist. He matched the newly discovered terrrestrial helium with corresponding lines in the solar spectrum. His name is associated with a series of spectral lines of hydrogen. In which range of the electromagnetic spectrum is the Paschen Series found? | |

| On 25 Feb of a certain year, Thomas Davenport patented the first practical electrical motor as "an application of magnetism and electro-magnetism to propelling machinery." The rotating electromagnets have cores of soft iron, wound with copper wire insulated with layers of silk. The wires from the coil run parallel down the shaft to touch copper contacts on the base. These wires make contact with different plates at each half-turn. In which decade was this patent issued? |
On 25 Feb 1616, because of his assertion that the earth moves around the sun, a scientist was ordered by Cardinal Bellarmine "to give up altogether the false doctrine... and if you should refuse... you should be imprisoned." Given such a choice, the scientist made a renouncement, but he knew that would not change the real facts of the Earth's motion. Who was this scientist? |
