Geochronology
Geochronology is the science of Chronological dating, determining the age of rock (geology), rocks, fossils, and sediments using signatures inherent in the rocks themselves. Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools such as paleomagnetism and stable isotope ratios. By combining multiple geochronological (and biostratigraphic) indicators the precision of the recovered age can be improved. Geochronology is different in application from biostratigraphy, which is the science of assigning sedimentary rocks to a known geological period via describing, cataloging and comparing fossil floral and faunal assemblages. Biostratigraphy does not ''directly'' provide an absolute age determination of a rock, but merely places it within an ''interval'' of time at which that fossil assemblage is known to have coexisted. Both disciplines work together hand in hand, however, to the point where they share the same syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bachelor Of Science
A Bachelor of Science (BS, BSc, B.S., B.Sc., SB, or ScB; from the Latin ') is a bachelor's degree that is awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Shaler, who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through the influence of Louis Agassiz, who had much to do in shaping the plans of this School." Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follo ...

Conjoined Twins
Conjoined twins, popularly referred to as Siamese twins, are twins joined '' in utero''. It is a very rare phenomenon, estimated to occur in anywhere between one in 50,000 births to one in 200,000 births, with a somewhat higher incidence in southwest Asia and Africa. Approximately half are stillborn, and an additional one-third die within 24 hours. Most live births are female, with a ratio of 3:1. Two possible explanations of the cause of conjoined twins have been proposed. The one that is generally accepted is ''fission'', in which the fertilized egg splits partially. The other explanation, no longer believed to be accurate, is ''fusion'', in which the fertilized egg completely separates, but stem cells (that search for similar cells) find similar stem cells on the other twin and fuse the twins together. Conjoined twins and some monozygotic, but not conjoined, twins share a single common chorion, placenta, and amniotic sac '' in utero''. Chang and Eng Bunker (1811–1874) we ...

Chang And Eng Bunker
Chang Bunker (จัน บังเกอร์) and Eng Bunker (อิน บังเกอร์) (May 11, 1811 – January 17, 1874) were Siamese (Thai)-American conjoined twins, conjoined twin brothers whose fame propelled the expression "Siamese twins" to become synonymous for conjoined twins in general. They were widely exhibited as curiosities and were "two of the nineteenth century's most studied human beings". The brothers were born in Rattanakosin Kingdom (1782–1932), Siam (now known as Thailand) to a family of Thai Chinese, Chinese descent and were brought to the United States in 1829. They became known to American and European audiences in "freak shows". Newspapers and the public were initially sympathetic to them, and within three years they left the control of their managers, who they thought were cheating them, and toured on their own. In early exhibitions, they were exoticized and displayed their athleticism; they later held conversations in English in a more ...
