A triplet is a set of three items, which may be in a specific order, or unordered. It may refer to:
In quantum mechanics, a triplet is a quantum state of a system with a spin of 1, such that there are three allowed values of the spin component: −1, 0 and +1.
Spin, in the context of quantum mechanics, is not a mechanical rotation but a more abstract concept that characterizes a particle's intrinsic angular momentum. It is particularly important for systems at atomic length scales, such as individual atoms, protons, or electrons.
Almost all molecules encountered in daily life exist in a singlet state, but molecular oxygen is an exception. At room temperature, O2 exists in a triplet state, which can only undergo a chemical reaction by making the forbidden transition into a singlet state. This makes it kinetically nonreactive despite being thermodynamically a strong oxidant. Photochemical or thermal activation can bring it into the singlet state, which makes it kinetically as well as thermodynamically a strong oxidant.
In a system with two spin-1/2 particles - for example the proton and electron in the ground state of hydrogen, measured on a given axis, each particle can be either spin up or spin down so the system has four basis states in all
Seal IV is the fourth studio album (and third self-titled album) by Seal. It follows the aborted sessions for Togetherland, which was scrapped because Seal thought it was not up to the standard of his previous work.
In the United Kingdom, the album debuted at number four. In the United States, it debuted at number three in the U.S. Billboard 200, making his highest charting album to date. The album sold over 1 million copies worldwide.
Seal (sometimes referred to as Seal II to avoid confusion with the 1991 album of the same name) is the second self-titled album of singer Seal. The album was released in 1994 on ZTT and Sire Records and features the worldwide smash hit single "Kiss from a Rose".
The image on the cover has since become nearly synonymous with Seal, in that it has appeared on several singles covers and was reused for his greatest hits album.
The United States Navy's Sea, Air and Land Teams, commonly known as the Navy SEALs, are the U.S. Navy's principal special operations force and a part of the Naval Special Warfare Command and United States Special Operations Command. One of the SEALs' primary functions is to conduct small-unit maritime military operations which originate from, and return to a river, ocean, swamp, delta, or coastline. SEALs can negotiate shallow water areas such as the Persian Gulf coastline, where large ships and submarines are limited due to depth. The Navy SEALs are trained to operate in all environments (Sea, Air, and Land) for which they are named. SEALs are also prepared to operate in a variety of climates, such as desert, arctic, and jungle.
All SEALs are male members of the United States Navy. The CIA's highly secretive Special Activities Division (SAD) and more specifically its elite Special Operations Group (SOG) recruits operators from the SEAL Teams. Joint Navy SEALs and CIA operations go back to the MACV-SOG during the Vietnam War. This cooperation still exists today and is seen in the wars in Iraq and Afghanistan.
