Charles River Dam
The Charles River Dam is a flood control structure on the Charles River in Boston, Massachusetts, located just downstream of the Leonard P. Zakim Bunker Hill Memorial Bridge, near Lovejoy Wharf, on the former location of the Warren Bridge. History The Charles River Dam was built by the U.S. Army Corps of Engineers. The structure also includes the "Colonel Richard Gridley Locks", named for General George Washington's first army engineer. Built and operational in 1978, the three locks can be crossed by pedestrians as well as bicyclists. It is part of the popular Boston Harborwalk. The dam contains three individual locks, with one wider than the other two to accommodate the occasional passing of a larger vessel. The structure also includes a fish passage. Six diesel-powered, 2700 horsepower turbo-charged engines drive six pumps with a combined capacity of about per minute or 8140 cubic feet per second (CFS). The dam controls the surface level of the river basin as well its tribut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dams In Massachusetts
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MA Route 99
Route 99 is a north–south state highway in metropolitan Boston, leading from the Boston neighborhood of Charlestown through the northern suburbs of Everett, Malden, and Melrose, and terminating in Saugus at U.S. Route 1 (US 1). Route description Route 99 begins where North Washington Street becomes New Rutherford Avenue on the north side of the Charlestown Bridge. This occurs at the intersection with Chelsea Street, situated above the northbound tunnel of U.S. Route 1. Route 99 travels as a limited access highway through Charlestown along New Rutherford Avenue, intersecting with ramps for U.S. Route 1 and passing under the Gilmore Bridge that connects Charlestown to Cambridge. New Rutherford Avenue becomes Rutherford Avenue and the route continues along it, until the route splits off into an underpass below Sullivan Square, where it turns northeastward. The route emerges to join Alford Street and crosses the Alford Street Bridge over the Mystic River. After pass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charlestown Bridge
The Charlestown Bridge, officially named the North Washington Street Bridge, is located in Boston and spans the Charles River. As the river's easternmost crossing, the bridge connects the neighborhoods of Charlestown and the North End. Completed in 1900 and given its current official name in 1910, the bridge carries a portion of the Freedom Trail linking to the USS Constitution and Bunker Hill. To the north of the bridge, Route 99 begins and the street becomes New Rutherford Avenue. Replacement of the bridge started in fall 2018 and is expected to be completed in 2023. History The first government-sanctioned ferry crossing of the Charles was chartered at this location in the 1630s. It was operated by various individuals until it was given to Harvard College "in perpetuity" in 1640, to support the college financially. In 1640, the Massachusetts General Court granted Harvard College the revenue from the Boston-Charlestown ferry to help support the institution. The Harvard C ...

US 1
U.S. Route 1 or U.S. Highway 1 (US 1) is a major north–south United States Numbered Highway that serves the East Coast of the United States. It runs from Key West, Florida, north to Fort Kent, Maine, at the Canadian border, making it the longest north–south road in the United States. US 1 is generally paralleled by Interstate 95 (I-95), though US 1 is significantly farther west (inland) between Jacksonville, Florida, and Petersburg, Virginia, while I-95 is closer to the coastline. In contrast, US 1 in Maine is much closer to the coast than I-95, which runs farther inland than US 1. The route connects most of the major cities of the East Coast—including Miami, Jacksonville, Raleigh, Richmond, Washington, D.C., Baltimore, Philadelphia, New York City, and Boston passing from the Southeastern United States to New England. While US 1 is generally the easternmost of the main north–south U.S. Highways, parts of several others occupy corridors closer to the o ...

Charlestown High Bridge
The Charlestown High Bridge (referred to as the John F. Fitzgerald Bridge on old AAA Tourbook maps) spanned the Charles River in Boston, Massachusetts and was part of I-93/ US 1 at the north end of the Central Artery. This double-decked truss bridge, built in 1954, was to originally carry I-95 through Boston from southwest to northeast in tandem with the Tobin Bridge, built in 1950. The I-95 project and several other highway projects in and around Boston, including both the highly controversial Inner Belt ( I-695) and the Southwest Corridor, completing the right-of-way intended to bring I-95 into Boston from Providence, Rhode Island, were cancelled due to heavy public opposition in the early 1970s. I-93 was allowed to be completed from the Yankee Division Highway ( Route 128) to the foot of the Charlestown High Bridge in 1969, and the I-93 designation was extended onto the bridge and the Central Artery in the early 1970s. Originally intended to carry 75,000 vehicles p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul Matisse
Paul Matisse (born 1933) is an artist and inventor known for his public art installations, many of which are interactive and produce sound. Matisse also invented the Kalliroscope. Early life and education Paul Matisse is the son of New York gallery owner Pierre Matisse, (the youngest son of painter Henri Matisse), and Alexina Sattler. His mother later divorced Pierre and married artist Marcel Duchamp, becoming Alexina "Teeny" Duchamp. Thus Paul is both grandson of Henri Matisse, and the stepson of Marcel Duchamp. In 1954, Matisse graduated from Harvard University, where he joined a long line of esteemed alumni who had lived in Eliot House while at Harvard. Matisse studied at Harvard's Graduate School of Design, and worked briefly with Buckminster Fuller. Artistic career Matisse worked in product development for Arthur D. Little. In 1962 he set off on his own, inventing (1966), patenting (1968), and ultimately manufacturing Kalliroscopes, which can display the complex an ...

Sea Water
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately of sea salt, dissolved salts (predominantly sodium () and chloride () ions). The average density at the surface is 1.025 kg/L. Seawater is density, denser than both fresh water and pure water (density 1.0 kg/L at ) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it Freezing, freezes at about . The coldest seawater still in the liquid state ever recorded was found in 2010, in a stream under an Antarctic glacier: the measured temperature was . Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the diffe ...
