Snap or SNAP may refer to:
In physics, jounce or snap is the fourth derivative of the position vector with respect to time, with the first, second, and third derivatives being velocity, acceleration, and jerk, respectively; hence, the jounce is the rate of change of the jerk with respect to time. Jounce is defined by any of the following equivalent expressions:
The following equations are used for constant jounce:
where
The notation (used in ) is not to be confused with the displacement vector commonly denoted similarly. Currently, there are no well-accepted designations for the derivatives of jounce. The fourth, fifth and sixth derivatives of position as a function of time are "sometimes somewhat facetiously" referred to as snap, crackle and pop respectively. Because higher-order derivatives are not commonly useful, there has been no consensus among physicists on the proper names for derivatives above jounce.
The dimensions of jounce are distance per (time to the power of 4). In SI units, this is "metres per quartic second", "metres per second per second per second per second", m/s4, m · s−4, or 100 Gal per second squared in CGS units. This pattern continues for higher order derivatives, with the 5th being m/s5.
Pillow Pals were a line of plush toys made by Ty, Inc. during the 1990s. The toys were given their name because they were soft like a pillow, and were made with children in mind. Though many of them resembled certain Beanie Babies, those that did not share names with their Beanie Baby counterparts. Such Pillow Pals saw a decline in popularity in the late 1990s with the introduction of Beanie Buddies, which were also larger versions of various Beanie Babies. In January 1999, all Pillow Pals were redesigned, and their colors were changed. This line did not sell well, and was discontinued by Ty around the end of the year. Today, PillowPals LLC takes children's drawings and replicates them into 3D pillows.
At the time of the final retirement, Ty donated its remaining stock of pillow pals to the Ronald McDonald House to be distributed to sick children.
The following Pillow Pals were made during the 1990s:
After the 1999 redesign, the following Pillow Pals were made:
The word scope may refer to many different devices or viewing instruments, constructed for many different purposes. Uses of scope or scopes may refer to:
Scope is a brand of mouthwash made by Procter & Gamble. It was introduced in 1966, and for many years has been positioned in the marketplace as the purportedly better-tasting alternative to Listerine, the longtime dominant mouthwash product.
Originally available only in mint flavor, Scope is still currently available in original mint (green), but also in a peppermint (blue) & new Scope White. The Citrus Splash flavor was discontinued due to insufficient demand to meet the slightly higher cost of production. There is a new Scope Outlast and a new logo; the old logo on the scope mouthwash is still on sale in available stores. Scope also manufactures "Dual-Blast" mouthwash, which is claimed to remove odors such as garlic and onion from the mouth and throat.
On March 26, 2013 Scope introduced a viral video campaign for a bacon flavored mouthwash. It was intended as an April Fools' Day joke.
The active ingredients of Scope Outlast are cetylpyridinium chloride, domiphen bromide, and denatured alcohol.
In computer programming, the scope of a name binding – an association of a name to an entity, such as a variable – is the part of a computer program where the binding is valid: where the name can be used to refer to the entity. In other parts of the program the name may refer to a different entity (it may have a different binding), or to nothing at all (it may be unbound). The scope of a binding is also known as the visibility of an entity, particularly in older or more technical literature – this is from the perspective of the referenced entity, not the referencing name. A scope is a part of a program that is or can be the scope for a set of bindings – a precise definition is tricky (see below), but in casual use and in practice largely corresponds to a block, a function, or a file, depending on language and type of entity. The term "scope" is also used to refer to the set of all entities that are visible or names that are valid within a portion of the program or at a given point in a program, which is more correctly referred to as context or environment.
