Balloon

A balloon is a flexible bag that can be inflated with a gas, such as helium, hydrogen, nitrous oxide, oxygen, or air. Modern day balloons are made from materials such as rubber, latex, polychloroprene, or a nylon fabric, and can come in many colors. Some early balloons were made of dried animal bladders, such as the pig bladder. Some balloons are used for decorative purposes, while others are used for practical purposes such as meteorology, medical treatment, military defense, or transportation. A balloon's properties, including its low density and low cost, have led to a wide range of applications.

The rubber balloon was invented by Michael Faraday in 1824, during experiments with various gases.

Applications

Decoration or entertainment

Party balloons are mostly made of a natural latex tapped from rubber trees, and can be filled with air, helium, water, or any other suitable liquid or gas. The rubber's elasticity makes the volume adjustable. As shown in the photo to the right, they can come in different colors like the rainbow such as red, orange, yellow, green, blue, purple, etc.

List of Beavis and Butt-head episodes

The following is an episode list for the MTV animated television series Beavis and Butt-Head. The series has its roots in 1992 when Mike Judge created two animated shorts, "Frog Baseball" and "Peace, Love and Understanding", which were later aired on Liquid Television of the Mike Judge Collection DVDs (see related page for a detailed listing).

Series overview

Episodes

Shorts (1992)

Both shorts originally aired as part of Liquid Television and did not include music videos.

Season 1 (1993)

Mike Judge himself is highly critical of the animation and quality of these episodes, in particular the first two – "Blood Drive"/"Give Blood" and "Door to Door" – which he described as "awful, I don't know why anybody liked it... I was burying my head in the sand."

Season 2 (1993)

Season 3 (1993-94)

Season 4 (1994)

Season 5 (1994–95)

Season 6 (1995–96)

Season 7 (1997)

Starting this season, the show switched to a 7-minute short act, with most of the shorts running approximately 5 minutes with one music video at the end.

Balloon (game)

Balloon, balloon-ball or wind-ball was a game similar to the modern game of volleyball in which a leather ball would be batted by the fist or forearm to prevent it from touching the ground. The game was played in ancient Rome where it was known as follis — the Latin word for a leather bag. Such a ball made of leather was quite heavy and so protection might be used such as a leather gauntlet or wooden bracer. When rubber became available from the New World, the game was played using lighter balls of inflated rubber and so younger boys could play too.

Cage (graph theory)

In the mathematical area of graph theory, a cage is a regular graph that has as few vertices as possible for its girth.

Formally, an (r,g)-graph is defined to be a graph in which each vertex has exactly r neighbors, and in which the shortest cycle has length exactly g. It is known that an (r,g)-graph exists for any combination of r ≥ 2 and g ≥ 3. An (r,g)-cage is an (r,g)-graph with the fewest possible number of vertices, among all (r,g)-graphs.

If a Moore graph exists with degree r and girth g, it must be a cage. Moreover, the bounds on the sizes of Moore graphs generalize to cages: any cage with odd girth g must have at least

vertices, and any cage with even girth g must have at least

vertices. Any (r,g)-graph with exactly this many vertices is by definition a Moore graph and therefore automatically a cage.

There may exist multiple cages for a given combination of r and g. For instance there are three nonisomorphic (3,10)-cages, each with 70 vertices : the Balaban 10-cage, the Harries graph and the Harries–Wong graph. But there is only one (3,11)-cage : the Balaban 11-cage (with 112 vertices).

Cage (enclosure)

A cage is an enclosure made of mesh, bars or wires, used to confine, contain or protect something or someone. A cage can serve many purposes, including keeping an animal in captivity, capturing, and being used for display of an animal at a zoo.

Humans

In history, prisoners were sometimes kept in a cage. They would sometimes be chained up inside into uncomfortable positions to intensify suffering.

History

Cages have been usually been used to capture or trapping a certain life form. For this reason, they've been known as a hunting accessory, often used for poaching animals or simply seizing them.

In captivity

Cages are often used now as a source to confine animals. These provide as a habitat to the animal, and since they've advanced so greatly, they are now specially designed to fit that species of animal. Captive breeds of birds, rodents, reptiles, and even larger animals have also been known to be confined in a cage as a domesticated animal (also known as a pet). Captivity is a common purpose of the cage.
