Under the Whyte notation for the classification of steam locomotives, represents one of the simplest possible types, that with two axles and four coupled wheels, all of which are driven. The wheels on the earliest four-coupled locomotives were connected by a single gear wheel, but from 1825 the wheels were usually connected with coupling rods to form a single driven set.

In organic chemistry, Zaitsev's rule (or Saytzeff's rule, Saytzev's rule) is an empirical rule for predicting the favored alkene product(s) in elimination reactions. While at the University of Kazan, Russian chemist Alexander Zaitsev studied a variety of different elimination reactions and observed a general trend in the resulting alkenes.

RULE REGARDING ACCEPTANCE BY POST OF OFFERS IN ANGLO-AMERICAN CONTRACT LAW
Mail box rule; Postal acceptance rule; Postal rule; Postage rule; Deposited acceptance rule; Mailbox rule; Postal exception
n. in contract law, making a written offer or acceptance of offer valid if sent in the mail, with postage, within the time in which the offer must be accepted, unless the offer requires acceptance by personal delivery on or before the specified date. The rule may also apply to mailing payments of insurance premiums when due. However, relying on this so-called "rule" can be dangerous, since the party awaiting the acceptance or payment may cancel the offer if there is no response in hand when the time runs out.

Cromwell's rule

Cromwell's rule, named by statistician Dennis Lindley, states that the use of prior probabilities of 1 ("the event will definitely occur") or 0 ("the event will definitely not occur") should be avoided, except when applied to statements that are logically true or false, such as 2+2 equaling 4.

The reference is to Oliver Cromwell, who wrote to the General Assembly of the Church of Scotland on 3 August 1650, shortly before the Battle of Dunbar, including a phrase that has become well known and frequently quoted:

I beseech you, in the bowels of Christ, think it possible that you may be mistaken.

As Lindley puts it, assigning a probability should "leave a little probability for the moon being made of green cheese; it can be as small as 1 in a million, but have it there since otherwise an army of astronauts returning with samples of the said cheese will leave you unmoved." Similarly, in assessing the likelihood that tossing a coin will result in either a head or a tail facing upwards, there is a possibility, albeit remote, that the coin will land on its edge and remain in that position.

If the prior probability assigned to a hypothesis is 0 or 1, then, by Bayes' theorem, the posterior probability (probability of the hypothesis, given the evidence) is forced to be 0 or 1 as well; no evidence, no matter how strong, could have any influence.

A strengthened version of Cromwell's rule, applying also to statements of arithmetic and logic, alters the first rule of probability, or the convexity rule, 0 ≤ Pr(A) ≤ 1, to 0 < Pr(A) < 1.
