Jounce

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 Pal

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.

List of Pillow Pals

The following Pillow Pals were made during the 1990s:

After the 1999 redesign, the following Pillow Pals were made:

Angel (Angel album)

Angel is the first album by the rock band Angel. "Tower", the keyboard-heavy opening track, was used widely during the late 1970s and early 1980s by album rock radio stations in the USA for various advertising purposes. The track is also on K-SHE radio's Classic List. This album can be seen as representing the band's early progressive roots, with Helluva Band seeing the group starting to move towards an increasingly hard rock-oriented sound. Tracks 6-8 segue to form a 10-minute mini suite.
