The Michigan English Test (MET) is a multilevel, modular English language examination, which measures English language proficiency in personal, public, occupational and educational contexts. [1] It is developed by CaMLA , a not-for-profit collaboration between the University of Michigan and the University of Cambridge and has been in use since ...
Probability theory or probability calculus is the branch of mathematics concerned with probability.Although there are several different probability interpretations, probability theory treats the concept in a rigorous mathematical manner by expressing it through a set of axioms.
[1]: 410–417 The total number of X and E is known as the steric number. For example in a molecule AX 3 E 2 , the atom A has a steric number of 5. When the substituent (X) atoms are not all the same, the geometry is still approximately valid, but the bond angles may be slightly different from the ones where all the outside atoms are the same.
Test anxiety is a combination of physiological over-arousal, tension and somatic symptoms, along with worry, dread, fear of failure, and catastrophizing, that occur before or during test situations. [1] It is a psychological condition in which people experience extreme stress, anxiety, and discomfort during and/or before taking a test.
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. [1] [2] Modern science is typically divided into two or three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the social sciences (e.g., economics, psychology, and sociology), which ...
In theoretical physics, Nordström's theory of gravitation was a predecessor of general relativity.Strictly speaking, there were actually two distinct theories proposed by the Finnish theoretical physicist Gunnar Nordström, in 1912 and 1913 respectively.
August Weismann's idea, set out in his 1892 book Das Keimplasma: eine Theorie der Vererbung (The Germ Plasm: a Theory of Inheritance), [32] was that the hereditary material, which he called the germ plasm, and the rest of the body (the soma) had a one-way relationship: the germ-plasm formed the body, but the body did not influence the germ ...
The expected utility hypothesis is a foundational assumption in mathematical economics concerning decision making under uncertainty.It postulates that rational agents maximize utility, meaning the subjective desirability of their actions.
