Even though the grades technically range from "1" to "5", "1" is not very common and is rarely given for academic reasons—in many cases a "1" is given as a result of failure to show up for an exam or to answer any questions. A "2" grade usually means that the student showed little or no knowledge in a subject.
The reader should identify ideas and formulate questions about the content of the chapter. Question ("Q") Generate questions about the content of the reading. For example, convert headings and sub-headings into questions, and then look for answers in the content of the text. Other more general questions may also be formulated:
Plus and minus signs are often used to further differentiate marks. For example, "2+" corresponds to the U.S. 'B+'. Half-intervals may also be used, such as "2–3", a grade halfway between 2 and 3. At the university level, only grades 1, 2 and 3 are passing; anything worse than 3 is automatically a failing grade.
The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...
The Crick, Brenner et al. experiment (1961) was a scientific experiment performed by Francis Crick, Sydney Brenner, Leslie Barnett and R.J. Watts-Tobin. It was a key experiment in the development of what is now known as molecular biology and led to a publication entitled "The General Nature of the Genetic Code for Proteins" and according to the historian of Science Horace Judson is "regarded ...
The Michelson–Gale–Pearson experiment (1925) is a modified version of the Michelson–Morley experiment and the Sagnac-Interferometer. It measured the Sagnac effect due to Earth's rotation , and thus tests the theories of special relativity and luminiferous ether along the rotating frame of Earth .
[6] [1] The experiment attempts to assess the subject's spatial reasoning. The subject is shown an upright bottle or glass with a water level marked, then shown pictures of the container tilted at different angles without the level marked and asked to mark where the water level would be.
Wheeler's cosmic interferometer uses a distant quasar with two paths to equipment on Earth, one direct and one by gravitational lensing. After [2]. In an attempt to avoid destroying normal ideas of cause and effect, some theoreticians [who?] suggested that information about whether there was or was not a second beam-splitter installed could somehow be transmitted from the end point of the ...
