The US became a science superpower after World War II due to the efforts of Vannevar Bush, who convinced President Franklin Roosevelt to fund advanced technology research in universities, leading to the development of cutting-edge technologies such as computers, rockets, and radar. In contrast, Britain's focus on military research and development labs, led by Professor Frederick Lindemann, did not lead to the same level of innovation and commercialization. The US government's funding of basic research in universities and the indirect cost reimbursement system played a crucial role in establishing the US as a leader in science and technology. This led to a brain drain, with top researchers flocking to the US, and enabled the country to maintain its position as a science superpower for over 85 years.
