Bull was born in Northbay, ranking ninth among 10 brothers and sisters. At the age of 3, his mother died, and his father, a lawyer, ran away from home. He was raised by his aunt and uncle. The misfortune of childhood made Bull sensitive. Lonely and irritable, but an excellent student at school. At the age of 22, he obtained a doctorate from the University of Toronto with honors, becoming the youngest doctor in the history of the university. Soon, he became famous for his outstanding talent in artillery technology and creation. 1953, a Canadian science magazine called him a "young rocket expert". 1961June was hired as a professor of engineering by McGill University in Montreal. 1964, the bull, who just turned 36, was the director of the Institute of Universe of the University.

"Super efficient harp system"

During his work in the Institute of Cosmology, he designed an "ultra-efficient harp system" with a length of 40 meters and a caliber of 1000 mm, which can shoot 2000 kilograms of warheads into low-earth orbit. This achievement made him famous. 1965, a middle-aged German woman quietly came to Montreal to visit Professor Bull. The woman's father was an engineer and participated in the "Paris Cannon Project" during the First World War. She obviously came with the manuscript of Rosenberg's "Paris Cannon". Rosenberg described the technical details of the cannon in the manuscript. Bull is an experienced ballistic expert. With this information, he copied the complete cannon on the drawing board.

Improve the "Paris cannon"

With her help, Bohr finally uncovered the "technical maze" hidden for nearly half a century and came up with a way to improve the "Paris cannon". Since then, he has formed an indissoluble bond with the super cannon. On the basis of summarizing predecessors' experience, after years of painstaking research, Boolean realized that modern artillery design was facing a revolution. He is eager to show his skills. Perhaps his popularity helped him, and the US Army's R&D department and the Canadian Department of Defense successively found him and proposed cooperation projects. With the strong support of the US and Canadian military, Bull set up a testing ground in Barbados in the Caribbean and started a secret mission codenamed "High-altitude Flight Research Program" (HARP).

Set up your own research laboratory.

In addition, with the help of the American and Canadian governments, Bohr even set up his own research laboratory in Quebec, which is hard to reach. Quebec is close to the border between Canada and the United States, which is convenient for Boers to communicate with the US military. Boolean believes that according to the principle of action and reaction, if the projectile of the giant gun is a rocket with thrust, its range will be greatly extended. So, in a relatively short period of time, he welded two cannons of the US Navy together to create a giant gun with a length of 36 meters and a caliber of 424 mm.

Barbados cannon

In the subsequent test shot, the gun successfully threw a 90 kg shell into space at a height of 180 km. This giant gun is also called "Barbados" gun because of its proving ground. It is said that this kind of artillery can also fire shells weighing 100 kilograms to 4000 kilometers away. The rocket extended-range warhead with a weight of 2 14kg was launched to a place 2570km away. Lighter aircraft carriers can be sent to a vertical height of more than 250 kilometers. Among the existing practical cannons in the world, the record maintained by this "Barbados" gun has not been broken so far. This work laid the foundation for the design of Bohr's later "super cannon".
