Antium

1. A type of metal used to build ships, airplanes, ect.
2. What Dorthy said in Wizard of Oz.Obviously she was trying to build something

1. Whoa, that's made out of antium...
Yup.
2 Antium?! Antium?! Oh, where are you antium?!

antimacatter 

A square of aluminum foil placed upon a surface to deter cats from walking on it.

After I saw John sitting on the closed lid of the record player I put a piece of aluminum foil on top of it to act as an antimacatter.

antimacassar 

An antimacasser is a small mat--usually crocheted or tatted but maybe embroidered on silk, linen, cotton or wool of woven cloth--which was used in Victorian and Edwardian times to protect the top back and sometimes arms of upholstered chairs and sofas from men's hair oil. Macassar oil was a common hair oil made from palm or coconut oil and usually scented with Ylang-ylang. The name is taken from the port of Makassar in Indonesia from which the product was imported.

The old lady's room was crowed with heavy mahogany furniture, deeply carved, upholstered with dusty, crimson plush with intricate crochet antimacassar mats draping the backs of the chairs, still emitting the faint, stale sent of the hair oil of by-gone generations of gentlemen.

Antimatter 

Antimatter is literally matter which is the inverse or opposite of matter; particles which have charges opposite of regular matter.

Antimatter was first predicted by P.A.M. Dirac in his theory of quantum mechanics in 1928. Antiparticles were found soon after by Carl Anderson. Since then, research centers such as CERN and Fermilab produce antimatter particles on a daily basis. CERN uses a Proton Synchrotron machine to accelerate protons and then they inject them into the Antiproton Decelerator - a gigantic circular machine with a diameter of 18 km. Here the protons are smashed into a copper or iridium block of metal. The abrupt stop from such an incredible speed (about the speed of light) results in an enormous amount of energy released into a small volume, resulting in extreme temperatures greater than 10,000,000,000,000 Celsius. This enormous amount of heat and energy results in the spontaneous creation of matter-antimatter particles.

When antimatter comes in contact with regular matter - earth, air, whatever - it annihilates immediately in a 100% efficient reaction. A popular misconception is that this antimatter-matter reaction will someday allow antimatter for use as a source of fuel, or power source. Unfortunately, this is an impossible reality. Since antimatter is not found anywhere on Earth naturally (obviously), it must be created. With the equation E=mc2, it is IMPOSSIBLE to have a net gain of matter: the energy required running the accelerators would ALWAYS be more than the energy antimatter produced.

It's true that a quarter gram of antimatter has as much power as the nuclear bomb dropped on Hiroshima. This raises concern as to whether it could eventually be yielded as a terrorist device. Fortunately, it is IMPOSSIBLE to collect and store antimatter at this great of a density, and even if it were possible, with the current technology it would take billions and billions of years to yield that much. In fact, if CERN were to have kept all of the antimatter it ever produced; it would be enough to power a light bulb for about three seconds. Anyways, even with these things aside, it's completely impractical considering how much time, money, and energy is required to create antimatter.

antimacassar 

An antimacassar is a small cloth placed over the backs or arms of chairs, or sofas. Historically, the Edwardian male penchant for oiling one's coiffure continued into Victorian times; necessitating the invention of washable decorative fabric blotters. They are still used in luxury rail lines and immaculate Japanese taxis.

The name is derived from the Indian unguent for the hair commonly used in the early 19th century, macassar oil— the poet Byron called it, "thine incomparable oil, Macassar."
They first came to have elaborate patterns, often in matching sets for the various items of parlour furniture; they were either made at home using a variety of techniques such as crochet or tatting, or purchased from drapers.

The original antimacassar was often made of white crochet-work, stiffened and uncomfortable, but in the third quarter of the 19th century it became simpler and was made of soft coloured stuffs, usually worked with a simple pattern in tinted wools or silk.
