Paraffins

the general term for the ALKANES, saturated ALIPHATIC HYDROCARBONS with the formula C_nH_2n+2. They are quite unreactive hence the name paraffin (from the Latin parum affinis, little allied).

In chemistry, paraffin is the common name for the alkane hydrocarbons with the general formula C_nH_2n+2. Paraffin wax refers to the solids with 20 ≤ n ≤ 40 .

The simplest paraffin molecule is that of methane, CH₄, a gas at room temperature. Heavier members of the series, such as that of octane, C₈H₁₈, and mineral oil appear as liquids at room temperature. The solid forms of paraffin, called paraffin wax, are from the heaviest molecules from C₂₀H₄₂ to C₄₀H₈₂. Paraffin wax was identified by Carl Reichenbach in 1830.

Paraffin, or paraffin hydrocarbon, is also the technical name for an alkane in general, but in most cases it refers specifically to a linear, or normal alkane — whereas branched, or isoalkanes are also called isoparaffins. It is distinct from the fuel known in Ireland, Britain and South Africa as paraffin oil or just paraffin, which is called kerosene in most of the U.S., Canada, Australia and New Zealand.

The name is derived from the Latin parum (= barely) + affinis with the meaning here of "lacking affinity", or "lacking reactivity". This is because alkanes, being non-polar and lacking in functional groups, are very unreactive.

Galaxy

(plural galaxies) specifically, the name given to the band of stars, numbering one hundred thousand million bodies, which includes the Sun, and is alternatively called the Milky Way. The galaxy has a spiral structure and is approximately one hundred thousand LIGHT YEARS across. In general usage it refers to a collection of stars held together by gravitational forces. They form different shapes including spiral, elliptical and irregular galaxies and range from dwarf galaxies with 100 000 stars to massive galaxies such as the giant elliptical M 87 which has three thousand billion stars.

_____________________________________________________________

A galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants, an interstellar medium of gas and dust, and an important but poorly understood component tentatively dubbed dark matter. The name is from the Greek root galaxias [γαλαξίας], meaning "milky," a reference to the Milky Way galaxy. Typical galaxies range from dwarfs with as few as ten million (10⁷) stars up to giants with one trillion (10¹²) stars, all orbiting the galaxy's center of mass. Galaxies can also contain many multiple star systems, star clusters, and various interstellar clouds. The Sun is one of the stars in the Milky Way galaxy; the Solar System includes the Earth and all the other objects that orbit the Sun.

Historically, galaxies have been categorized according to their apparent shape (usually referred to as their visual morphology). A common form is the elliptical galaxy, which has an ellipse-shaped light profile. Spiral galaxies are disk-shaped assemblages with dusty, curving arms. Galaxies with irregular or unusual shapes are known as peculiar galaxies, and typically result from disruption by the gravitational pull of neighboring galaxies. Such interactions between nearby galaxies, which may ultimately result in galaxies merging, may induce episodes of significantly increased star formation, producing what is called a starburst galaxy. Small galaxies that lack a coherent structure could also be referred to as irregular galaxies.

There are probably more than 100 billion (10¹¹) galaxies in the observable universe. Most galaxies are 1,000 to 100,000^[4] parsecs in diameter and are usually separated by distances on the order of millions of parsecs (or megaparsecs). Intergalactic space (the space between galaxies) is filled with a tenuous gas of an average density less than one atom per cubic meter. The majority of galaxies are organized into a hierarchy of associations called clusters, which, in turn, can form larger groups called superclusters. These larger structures are generally arranged into sheets and filaments, which surround immense voids in the universe.

Although it is not yet well understood, dark matter appears to account for around 90% of the mass of most galaxies. Observational data suggests that supermassive black holes may exist at the center of many, if not all, galaxies. They are proposed to be the primary cause of active galactic nuclei found at the core of some galaxies. The Milky Way galaxy appears to harbor at least one such object within its nucleus.

Five Resume Writing Tips

A resume introduces you to an employer. It should:

• State the job you want and include your name, address and telephone number. The resume lists your job or school experience, your education, skills and relevant personal information, such as job-related hobbies.

• Be typed or printed on quality paper. And it must be absolutely perfect. It must be no longer than two pages.

• List those qualifications and experiences that are relevant to the job for which you are applying. If you are applying for a first job, include responsibilities at school or in clubs.

• Be specific about your background without getting too detailed. Be positive.

• Be simple and easy to read. Check with your library or guidance counselor for good formats.
