I need some help with a list.I urge all those from the left and the right to participate.
- Thread starter PatPatriot
- Start date
concorde
aircraft carriers
Global positioning system.
nuclear stuff - all of it.
The Pyramids.
Rome.
The Great Wall of China.
Skylab.
The Apollo etc program.
The SR71 program.
Public health programs - eg The Water system
Public transport - eg The freeway system
The channel tunnel.
The Hoover Dam.
Only big government has the deep pockets to bankroll certain stuff, (using private labour).

Oh, the first electronic (valves in those days) computer.
Colossus
Further codebreaking success enabled Bletchley Park to exploit Lorenz, a highly sophisticated cipher used personally by Hitler and his High Command. But many of the messages still took several weeks to decipher - a computing machine was needed. The result was Colossus, the world's first programmable electronic computer, designed by Max Newman.
Colossus was the size of a living room and weighed about one tonne. Its 2,400 valves replicated the pattern of an encrypted Lorenz message as electrical signals. This breakthrough in computing remained a secret for many years, to the extent that two Americans took the credit for inventing the computer in 1945. But the creation of Colossus proved to be a key contributor to the success on D-Day.
Influence
Colossus was a highly secret device, and had therefore not much influence on the development of later computers. Nearly all documentation and machinery was classified immediately after the war, and destroyed in 1960s. It is said that Winston Churchill specifically ordered the destruction of the Colossus machines into 'pieces no bigger than a man's hand' and that Tommy Flowers personally burned the blueprints in a furnace at Dollis Hill. Information about Colossus reemerged in the 1970s. Due to this secrecy, Colossus was not able to be included in the history of computing for many years.
