The Manhattan Project was a research and development program, led by the United States with participation from the United Kingdom and Canada, that produced the first atomic bomb during World War II. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the US Army Corps of Engineers. The Army component of the project was designated the Manhattan District; "Manhattan" gradually superseded the official codename, "Development of Substitute Materials", for the entire project. Along the way, the Manhattan Project absorbed its earlier British counterpart, Tube Alloys.
The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (roughly equivalent to $25.8 billion as of 2012). Over 90% of the cost was for building factories and producing the fissionable materials, with less than 10% for development and production of the weapons. Research and production took place at more than 30 sites, some secret, across the United States, the United Kingdom and Canada. Two types of atomic bomb were developed during the war. A relatively simple gun-type fission weapon was made using uranium-235, an isotope that makes up only 0.7 percent of natural uranium. Since it is chemically identical to the main isotope, uranium-238, and has almost the same mass, it proved difficult to separate. Three methods were employed for uranium enrichment: electromagnetic, gaseous and thermal. Most of this work was performed at Oak Ridge, Tennessee.
Manhattan (/mænˈhætən/) is the most densely populated and the oldest of the five boroughs of New York City. Located primarily on the island of Manhattan at the mouth of the Hudson River, the boundaries of the borough are identical to those of New York County, an original county of the U.S. state of New York. The borough and county consist of Manhattan Island and several small adjacent islands: Roosevelt Island, Randall's Island, Wards Island, Governors Island, Liberty Island, part of Ellis Island,Mill Rock, and U Thant Island; as well as Marble Hill, a very small area on the mainland bordering the Bronx. The original city of New York began at the southern end of Manhattan, expanded northward, and then between 1874 and 1898, annexed land from surrounding counties.
The New York County is the most densely populated county in the United States, and one of the most densely populated areas in the world, with a 2010 population of 1,585,873 living in a land area of 22.96 square miles (59.5 km2), or 69,464 residents per square mile (26,924/km²), more dense than any individual American city. It is also one of the wealthiest counties in the United States, with a 2005 per capita income above $100,000. Manhattan is the third-largest of New York's five boroughs in population, and its smallest borough in land area.

Imagine a time when it all began
In the dying days of the war
A weapon that would settle the score
Whoever found it first
Would be sure to do their worst
They always had before
Imagine a man where it all began
A scientist pacing the floor
In each nation, always eager to explore
To build the best big stick
To turn the winning trick
But this was something more
The big bang took and shook the world
Shot down the rising sun
The end was begun and it hit everyone
When the chain reaction was done
The big shots tried to hold it back
Fools tried to wish it away
The hopeful depend on a world without end
Whatever the hopeless may say
Imagine a place where it all began
Gathered from across the land
To work in the secrecy of the desert sand
All of the brightest boys
To play with the biggest toys
More than they bargained for
The big bang took and shook the world
Shot down the rising sun
The hopeful depend on a world without end
Whatever the hopeless may say
Imagine a man when it all began
The pilot of "Enola gay"
Flying out of the shockwave on that August day
All the powers that be
And the course of history
Would be changed forevermore
The big bang took and shook the world
Shot down the rising sun
The end was begun and it hit everyone
When the chain reaction was done
The big shots tried to hold it back
Fools tried to wish it away
The hopeful depend on a world without end
Whatever the hopeless may say
The big bang took and shook the world
Shot down the rising sun
The hopeful depend on a world without end
