The following sections list exceptions to the basic form; many are not exceptions to the augmented forms. Words that break both the "I before E" part and the "except after C" part of the rule include cheiromancies, cleidomancies, eigenfrequencies, obeisancies and oneiromancies, as well as Pleistocene from the geologic time scale.
Proving the validity of a rule of thumb. "The exception that proves the rule" is often used to describe a case (the exception) which serves to highlight or confirm (prove) a rule to which the exception itself is apparently contrary. Fowler describes two versions of this use, one being the "loose rhetorical sense" and the other "serious nonsense ...
Although a useful rule of thumb, there are exceptions to the LIATE rule. A common alternative is to consider the rules in the "ILATE" order instead. Also, in some cases, polynomial terms need to be split in non-trivial ways. For example, to integrate , one would set
Lipinski's rule of five. Lipinski's rule of five, also known as Pfizer's rule of five or simply the rule of five (RO5), is a rule of thumb to evaluate druglikeness or determine if a chemical compound with a certain pharmacological or biological activity has chemical properties and physical properties that would likely make it an orally active ...
Rule of thumb. In English, the phrase rule of thumb refers to an approximate method for doing something, based on practical experience rather than theory. [1][2][3] This usage of the phrase can be traced back to the 17th century and has been associated with various trades where quantities were measured by comparison to the width or length of a ...
Octet rule. The bonding in carbon dioxide (CO 2): all atoms are surrounded by 8 electrons, fulfilling the octet rule. The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a ...
In this form, it continues to be an important rule of thumb, with only a few known exceptions, [10] including David Sulzer and Stephen Rayport's finding that dopamine neurons also release glutamate as a neurotransmitter, but at separate release sites. [11]
In probability theory, the central limit theorem (CLT) states that, under appropriate conditions, the distribution of a normalized version of the sample mean converges to a standard normal distribution. This holds even if the original variables themselves are not normally distributed. There are several versions of the CLT, each applying in the ...
