December 12 2013 Radioisotopes are used in the branch of nuclear medicine to convey information on the operation of a person’s organs‚ or to treat specific diseases. Most of the time‚ radioisotopes are used by physicians and other scientists such as chemists‚ to make a quick and precise diagnoses of the patient’s illness. The bones‚ heart‚ and thyroid can easily be viewed or imaged with the use of radioisotopes in medicine. Additionally‚ in some cases radioisotopes can be used to treat diseased

1930’s called atomic beam magnetic resonance. 1949 Using Rabi’s technique‚ NIST (then the National Bureau of Standards) announces the world’s first atomic clock using the ammonia molecule as the source of vibrations. 1952 NIST announces the first atomic clock using cesium atoms as the vibration source. This clock is named NBS-1. 1954 NBS-1 is moved to NIST’s new laboratories in Boulder‚ Colo. 1955 The National Physical Laboratory in England builds the first cesium-beam clock used as a

Microscope Microscopes are instruments that produce a magnified image of a small object. They are used in many scientific and industrial applications. Some common applications for microscopes include manufacturing inspection and high-technology quality control. Specific quality control applications for microscopes include semiconductor processing‚ medical imaging‚ cell research‚ and metallurgical analysis. Microscopes are supplied in one of three common configurations‚ student‚ benchtop‚ and research

17th-century English colonial architecture resembles the late medieval forms that survived in rural England. Houses were built in a range of sizes. Gables‚ overhangs‚ and lack of symmetry reflected the late medieval style of Europe. In Virginia and Maryland‚ brick construction was preferred for the typically story and a half homes with chimneys at both ends and a more nearly symmetrical facade. Aside from fortifications‚ the principal nondomestic structures in the 17th-century colonies were churches
