In the United States, the formally recognized traditional Doctor of Science is an academic research doctoral degree awarded by research universities. The academic research Sc.D. (or D.Sc.) is considered by both the United States Department of Education and the National Science Foundation to be equivalent to the more commonly awarded Ph.D.
The first North American Sc.D. was inaugurated by Harvard University in 1872, when graduate studies first began at Harvard, and where the Ph.D. and Sc.D. degrees were introduced in the same year. The Doctor of Science research degree is earned with the formal dissertation defense and approval of a committee on the basis of original research and publications, and it is awarded predominantly in doctoral-level science programs, such as engineering, medical and health sciences, and health economics.
Although rarer than the Doctor of Philosophy, the Doctor of Science research degree has been awarded by institutions such as Columbia University, Harvard University, Johns Hopkins University, Massachusetts Institute of Technology, Robert Morris University and Tulane University.
A few university doctoral research programs offer both the Sc.D. and Ph.D. degrees in the same academic field, such as Johns Hopkins University and Massachusetts Institute of Technology, with identical requirements for obtaining either. Currently, research programs that offer the formal research Sc.D. but not the Ph.D. degree for a given field include several doctoral programs at Harvard University, Boston University, Capitol College, and Dakota State University.
There are programs where the Sc.D. and Ph.D. have different degree requirements, though the two degrees are officially considered equivalent. The Engineering school at Washington University in St. Louis, for example, requires four graduate courses in the D.Sc. program not required for the Ph.D. degree, while the Ph.D requires teaching assistance services. The Johns Hopkins University also offers both Ph.D. and Sc.D. in certain programs, with only minor differences in university administration of the degrees. In some institutions, the Sc.D. has been converted to the Ph.D. For instance, the doctoral degree in biostatistics at Harvard recently converted from Sc.D. to Ph.D., even though the doctoral degree structure and requirements have remained identical.

Famous quotes related to united states:
“... when we shall have our amendment to the Constitution of the United States, everyone will think it was always so, just exactly as many young people believe that all the privileges, all the freedom, all the enjoyments which woman now possesses were always hers. They have no idea of how every single inch of ground that she stands upon to-day has been gained by the hard work of some little handful of women of the past.”
—Susan B. Anthony (1820–1906)
“The United States is a republic, and a republic is a state in which the people are the boss. That means us. And if the big shots in Washington don’t do like we vote, we don’t vote for them, by golly, no more.”
—Willis Goldbeck (1900–1979)
“In the United States all business not transacted over the telephone is accomplished in conjunction with alcohol or food, often under conditions of advanced intoxication. This is a fact of the utmost importance for the visitor of limited funds ... for it means that the most expensive restaurants are, with rare exceptions, the worst.”
—John Kenneth Galbraith (b. 1908)
“An alliance is like a chain. It is not made stronger by adding weak links to it. A great power like the United States gains no advantage and it loses prestige by offering, indeed peddling, its alliances to all and sundry. An alliance should be hard diplomatic currency, valuable and hard to get, and not inflationary paper from the mimeograph machine in the State Department.”
—Walter Lippmann (1889–1974)
“Nova Scotia, New Brunswick, and Canada are the horns, the head, the neck, the shins, and the hoof of the ox, and the United States are the ribs, the sirloin, the kidneys, and the rest of the body.”
—William Cobbett (1762–1835)
