Boston Harbor

Boston Harbor is a natural harbor and estuary of Massachusetts Bay, and is located adjacent to the city of Boston, Massachusetts. It is home to the Port of Boston, a major shipping facility in the northeastern United States.

History

Since its discovery by John Smith in 1614, Boston Harbor has been an important port in American history. It was the site of the Boston Tea Party as well as almost continuous backfilling of the harbor until the 19th century. By 1660 almost all imports came to the greater Boston area and the New England coast through the waters of Boston Harbor. A rapid influx of people transformed Boston into a booming city. The health of the harbor quickly decreased as the population of Boston increased. As early as the late 19th century Boston citizens were advised not to swim in any portion of the Harbor. In the 1800s two of the first steam sewage stations were built (one in East Boston and one later on Deer Island). With these mandates the harbor was seeing small improvements, but raw sewage was still continuously pumped into the harbor. In 1919 the Metropolitan District Commission was created to oversee and regulate the quality of harbor water. However, not much improvement was seen and general public awareness of the poor quality of water was very low. In 1972 the Clean Water Act was passed in order to help promote increased national water quality.

Bermuda Triangle

Coordinates: 25°N 71°W / 25°N 71°W / 25; -71

The Bermuda Triangle, also known as the Devil's Triangle, is a loosely defined region in the western part of the North Atlantic Ocean, where a number of aircraft and ships are said to have disappeared under mysterious circumstances. According to the US Navy, the triangle does not exist, and the name is not recognized by the US Board on Geographic Names.Popular culture has attributed various disappearances to the paranormal or activity by extraterrestrial beings. Documented evidence indicates that a significant percentage of the incidents were spurious, inaccurately reported, or embellished by later authors. In a 2013 study, the World Wide Fund for Nature identified the world’s 10 most dangerous waters for shipping, but the Bermuda Triangle was not among them.

Triangle area

The first written boundaries date from an article by Vincent Gaddis in a 1964 issue of the pulp magazine Argosy, where the triangle's three vertices are in Miami, Florida peninsula; in San Juan, Puerto Rico; and in the mid-Atlantic island of Bermuda. But subsequent writers did not follow this definition. Some writers give different boundaries and vertices to the triangle, with the total area varying from 1,300,000 to 3,900,000 km² (500,000 to 1,510,000 sq mi). Consequently, the determination of which accidents have occurred inside the triangle depends on which writer reports them. The United States Board on Geographic Names does not recognize this name, and it is not delimited in any map drawn by US government agencies.

Big Bang

The Big Bang theory is the prevailing cosmological model for the universe from the earliest known periods through its subsequent large-scale evolution. The model accounts for the fact that the universe expanded from a very high density and high temperature state, and offers a comprehensive explanation for a broad range of phenomena, including the abundance of light elements, the cosmic microwave background, large scale structure and Hubble's Law. If the known laws of physics are extrapolated beyond where they are valid, there is a singularity. Modern measurements place this moment at approximately 13.8 billion years ago, which is thus considered the age of the universe. After the initial expansion, the universe cooled sufficiently to allow the formation of subatomic particles, and later simple atoms. Giant clouds of these primordial elements later coalesced through gravity to form stars and galaxies.

Boston

Boston (pronounced ⁱ/ˈbɒstən/) is the capital and largest city of the Commonwealth of Massachusetts in the United States. Boston also served as the historic county seat of Suffolk County until Massachusetts disbanded county government in 1999. The city proper covers 48 square miles (124 km²) with an estimated population of 655,884 in 2014, making it the largest city in New England and the 24th largest city in the United States. The city is the economic and cultural anchor of a substantially larger metropolitan area called Greater Boston, home to 4.7 million people and the tenth-largest metropolitan statistical area in the country. Greater Boston as a commuting region is home to 8.1 million people, making it the sixth-largest combined statistical area in the United States.

One of the oldest cities in the United States, Boston was founded on the Shawmut Peninsula in 1630 by Puritan settlers from England. It was the scene of several key events of the American Revolution, such as the Boston Massacre, the Boston Tea Party, the Battle of Bunker Hill, and the Siege of Boston. Upon American independence from Great Britain, the city continued to be an important port and manufacturing hub, as well as a center for education and culture. Through land reclamation and municipal annexation, Boston has expanded beyond the original peninsula. Its rich history attracts many tourists, with Faneuil Hall alone drawing over 20 million visitors per year. Boston's many firsts include the United States' first public school, Boston Latin School (1635), and first subway system (1897).
