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.

The following Pillow Pals were made during the 1990s:

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

Waves is the seventh album by Norwegian jazz guitarist Terje Rypdal recorded in 1977 and released on the ECM label.

Reception

The Allmusic review by Michael P. Dawson awarded the album 4 stars stating "This contains some of Rypdal's jazziest music".

Waves (Jade Warrior album)

Waves is the fifth studio album by the British progressive/experimental rock band Jade Warrior released in 1975 by Island Records. The album, written, recorded and produced by Jon Field and Tony Duhig with guest musicians (Steve Winwood among them) consisted of one single composition which in the pre-CD days had to be divided into two parts to fit A and B sides.

Style and concept

Jade Warrior's second of the four Island albums was dedicated to "the last whale". It had no recurring theme and was marked by a slightly jazzier feel than its predecessor, carrying a listener "through dawn-lit countryside full of birdsong, downriver to the ocean, and out among the great whales". Describing the band's musical vision at the time as "increasingly exotic", AllMusic found the Island albums "dreamlike, pushing a lighter jazz sound to the forefront", featuring "myriad percussive sounds but drum kits were rarely in evidence". "The band liked to create a soothing, ethereal feel, then shatter it with gongs and unexpectedly raucous electric guitar, usually from guest David Duhig, Tony's brother. The albums featured occasional celebrity guests such as Steve Winwood, but Jade Warrior had a style of its own", critic Casey Elston wrote.
