Energy (journal)
Energy is a peer-reviewed academic journal covering research on energy engineering that was established in 1976. It is published by Elsevier and the editor-in-chief is Henrik Lund (Aalborg University). According to the Journal Citation Reports, the journal has a 2013 impact factor of 4.159, ranking it 13th out of 83 journals in the category "Energy & Fuels" and second out of 55 journals in "Thermodynamics".

Relationship to energy in physics
Energy in this context is not, strictly speaking, the same as the conventional notion of energy in physics and the other sciences. The two concepts are, however, closely related, and it is possible to convert from one to the other:
For example, if x(t) represents the potential (in volts) of an electrical signal propagating across a transmission line, then Z would represent the characteristic impedance (in ohms) of the transmission line. The units of measure for the signal energy would appear as volt2·seconds, which is not dimensionally correct for energy in the sense of the physical sciences. After dividing by Z, however, the dimensions of E would become volt2·seconds per ohm, which is equivalent to joules, the SI unit for energy as defined in the physical sciences.

Seven Year Itch (Collective Soul album)
On September 18, 2001, Collective Soul released their greatest hits compilation Seven Year Itch: Greatest Hits, 1994-2001 (stylized as 7even Year Itch). The compilation includes songs recorded from 1994 to 2001 and included two new tracks; "Next Homecoming" and "Energy". Seven Year Itch received decent reviews and was relatively successful It sold 225,000 copies in the first year after its release and reached number fifty on the Billboard 200; in Canada, it reached number nine on its albums chart and went platinum. All the songs in Seven Year Itch had charted in the US on the Billboard Hot 100, Mainstream Rock Tracks, or the Modern Rock Tracks chart, except for "Energy", which debuted in this compilation.
The compilation has sold over 500,000 copies. It saw a resurgence in sales after Collective Soul began putting out albums on their own independent label, El Music Group, beginning in 2004.
Seven Year Itch was the last album Collective Soul released through Atlantic Records and their last album to feature guitarist Ross Childress, who had been with the band since its 1993/1994 debut.
Taffy (candy)
Taffy, or chews, are a type of candy similar to toffee. Taffy is often sold alongside bubblegum and hard candy. Taffy is made by stretching or pulling a sticky mass of boiled sugar, butter or vegetable oil, flavorings, and coloring until it becomes aerated (meaning that tiny air bubbles are produced, resulting in a light, fluffy and chewy candy). When this process is complete, the taffy is rolled, cut into small pastel-coloured pieces and wrapped in wax paper to keep it soft. It usually has a fruity flavor, but other flavors are common as well, including molasses and the classic unflavored taffy.
Salt water taffy was a noted invention of Atlantic City, New Jersey, and became a common souvenir of many coastal resort towns. Modern commercial taffy is made primarily from corn syrup, glycerin and butter. The pulling process, which makes the candy lighter and chewier, consists of stretching out the mixture, folding it over and stretching it out again. Although it is called "salt water" taffy, it does not include any salt water in its manufacture at all. In the nearby Philadelphia regional dialect, the term "taffy", without "salt water" before it, used to refer to a lollipop or sucker.
Battle off Samar
The Battle off Samar was the centermost action of the Battle of Leyte Gulf, one of the largest naval battles in history, which took place in the Philippine Sea off Samar Island, in the Philippines on October 25, 1944. As the only major action in the larger battle where the Americans were largely unprepared against the opposing forces, it has been cited by historians as one of the greatest military mismatches in naval history.
Adm. William Halsey, Jr. was lured into taking his powerful 3rd Fleet after a decoy fleet, leaving only three escort carrier groups of the 7th Fleet. The escort carriers and destroyer escorts which had been designed to protect slow convoys from submarine attack had been repurposed to attack ground targets, and had few torpedoes as they could normally rely on Halsey's fleet to protect them from any threats from armored warships. A Japanese surface force of battleships and cruisers, battered earlier in the larger battle and thought to have been in retreat, instead turned around unobserved and stumbled upon the northernmost of the three groups, Task Unit 77.4.3 ("Taffy 3"), commanded by Rear Admiral Clifton Sprague. Taffy 3's few destroyers and slower destroyer escorts possessed neither the firepower nor armor to effectively oppose the Japanese force, but nevertheless desperately attacked with 5 in (127 mm)/38 cal guns and torpedoes to cover the retreat of their slow "jeep" carriers. Aircraft from the carriers of Taffy 1, 2, and 3, including FM-2 Wildcats, F6F Hellcats and TBM Avengers, strafed, bombed, torpedoed, rocketed, depth-charged, fired at least one .38 caliber handgun and made numerous "dry" runs at the attacking force when they ran out of ammunition.
