Can you visualize the growth and development of useful scientific tool ?

Explanation

Yes, For example, E.O. Lawarance was the first to bulid an operation cyclotron for the study of subatomic particles in the year 1930. This cyclotron had a circumferece of about 13 inches. In contrast, the latest cyclotron developed is a super conducting super collider (SSC), which has a cirucfrence of about 52 miles. The machine has cost about 10 billion dollars and can give particles 100 million times more energy. The researches from SSC have led us to new methods of treating cancer and AIDS , and development of more advanced computers.
