The North America Portal

North America is a continent in the Earth's northern hemisphere and western hemisphere. It is bordered on the north by the Arctic Ocean, on the east by the North Atlantic Ocean, on the southeast by the Caribbean Sea, and on the south and west by the North Pacific Ocean; South America lies to the southeast. It covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 4.8% of the planet's surface or about 16.5% of its land area. As of July 2008, its population was estimated at nearly 529 million people. It is the third-largest continent in area, following Asia and Africa, and the fourth in population after Asia, Africa, and Europe. North America and South America are collectively known as the Americas or simply America.

North and South America are generally accepted as having been named after the Italian explorer Amerigo Vespucci, who explored South America between 1497 and 1502, and was the first European to suggest that the Americas were not the East Indies. Scientists have several theories as to the origins of the early human population of North America. The indigenous peoples of North America themselves have many creation myths, by which they assert that they have been present on the land since its creation. Before contact with Europeans, the natives of North America were divided into many different polities, from small bands of a few families to large empires. They lived in several "culture areas", which roughly correspond to geographic and biological zones and give a good indication of the main lifeway or occupation of the people who lived there.

Flag of Mexico
The Flag of the United Mexican States or Mexico is a vertical tricolor of green, white, and red with the national coat of arms charged in the center of the white stripe. While the meaning of the colors has changed over time, these three colors were adopted by Mexico following independence from Spain during the country's War of Independence. The current flag was adopted in 1968, but the overall design has been used since 1821, when the First National Flag was created. The current law of national symbols, Law on the National Arms, Flag, and Anthem, that governs the use of the national flag has been in place since 1984. France was the inspiration of those who detached Mexico from Spain in 1821, and they devised a new tricolor based on the flag of the liberation army. At that time the Italian tricolor was not in use. The flag now contains the coat of arms, in order to distinguish it from that of Italy. Red, white, and green are the colors of the national liberation army in Mexico. The central emblem is the Aztec pictogram for Tenochtitlan (now Mexico City), the center of their empire. It recalls the legend that inspired the Aztecs to settle on what was originally a lake-island. The form of the coat of arms was most recently revised in 1968. Aztec legend held that they should found their city on the spot where they saw an eagle on a cactus, eating a snake. Ribbon in the national colors at are the bottom of the coat of arms. Throughout history, the flag has changed 4 times, as the design of the coat of arms and the length-width ratios of the flag have been modified.

Log in Petrified Forest National Park

A petrified log in Petrified Forest National Park, located in northeastern Arizona, USA. The pieces of wood found in the park are mostly of the extinct species Araucarioxylon arizonicum. The logs were buried under volcanic ash, which was the source of the silica that helped to permineralize the buried logs, replacing wood with silica, colored with oxides of iron and manganese.

Selected biography

Muntz matchbook
Earl William "Madman" Muntz (January 3, 1914 – June 21, 1987) was an American businessman and engineer who sold and promoted cars and consumer electronics in the United States from the 1930s until his death in 1987. He was a pioneer in television commercials with his oddball "Madman" persona – an alter ego who generated publicity with his unusual costumes, stunts, and outrageous claims. Muntz also pioneered car stereos by creating the Muntz Stereo-Pak, better known as the 4-track cartridge, a predecessor to the 8-track cartridge developed by Lear Industries.

He invented the practice that came to be known as Muntzing, which involved simplifying otherwise complicated electronic devices. Muntz produced and marketed the first black-and-white television receivers to sell for less than $100, and created one of the earliest functional widescreen projection TVs. The Sarasota Herald-Tribune, Detroit News and Los Angeles Times credit him with coining the abbreviation "TV" for television, although the term had earlier been in use in call letters for stations such as WCBS-TV.

Selected quote

A good many of you are probably acquainted with the old proverb, “Speak softly and carry a big stick — you will go far.” If a man continually blusters, if he lacks civility, a big stick will not save him from trouble, and neither will speaking softly avail, if back of the softness there does not lie strength, power.
Theodore Roosevelt Minnesota State Fair, 3 September 1901
