Radioactivity can be used as a clock to measure time in the universe. Datations were made for fossils, art masterpieces and also for the earth, the solar system and universe. X-rays diffraction proved to be a powerful tool for studying crystals and molecules, in particular protein, and in enabled to demonstrate the DNA double helix.
Hence X-rays and radioactivity originated a revolution in physics and science and in the vision of nature. The imperceptible and yet so powerful rays demonstrated the deficiencies of our senses. Mathematical entities and instrumentation must complement our sensations.
The huge increment in our knowledge is accompanied by a divorce between the scientist and the layman who now often has great difficulties understanding new concepts not only in physics but also in biology. Abstract W. Detectives touted the use of Roentgen devices in following unfaithful spouses, and lead underwear was manufactured to foil attempts at peeking with "X-ray glasses.
As frivolous as such reactions may seem, the medical community quickly recognized the importance of Roentgen's discovery. Soon attempts were made to insert metal rods or inject radio-opaque substances to give clear pictures of organs and vessels, with mixed results. The first angiography, moving-picture X-rays, and military radiology, were performed in early In addition to the diagnostic powers of X-rays, some experimentalists began applying the rays to treating disease.
Since the early 19th century, electrotherapy had proved popular for the temporary relief of real and imagined pains. The same apparatus could generate X-rays. In January , only a few days after the announcement of Roentgen's work, a Chicago electrotherapist named Emil Grubbe irradiated a woman with a recurrent cancer of the breast, and by the end of the year, several researchers had noted the palliative effects of the rays on cancers.
Others found remarkable results in the treatment of surface lesions and skin problems while others investigated the possible bacterial action of the rays. X-rays even found cosmetic uses in depilatory clinics set up in the US and France.
Roentgen was awarded the first Nobel Prize in physics in for his discovery. When asked what his thoughts were at the moment of discovery, he replied, true to form, "I didn't think, I investigated. He rejected a title that would have given him entry into the German nobility, and donated his Nobel Prize money to his university. While he accepted the honorary degree of doctor of medicine offered to him by his own university, he never took out any patents on X-rays, to ensure that the world could freely benefit from his work.
For the first time in 40 years, the Republican Party wins control of both the U. House of Representatives and the Senate in midterm congressional elections.
