What role do physicists play in the advancement of human civilisation?
If it weren’t for physicists, the world as we know it, would be a very different place. I cannot imagine what life is like for the uncontacted North Sentinelese tribe which has none of our modern technology. If all modes of transportation and communication ceased to exist for a minimum of 30 days, how would your life be? Would the human race survive? It is these types of questions that drive physicists to constantly develop new technologies. Most of the cutting-edge technology used in the 20th century was developed by physicists collaborating with professionals from various disciplines. For example, in 1938, Lise Meitner and Otto Frisch discovered nuclear fission, which was used to build nuclear bombs and is used today in nuclear power plants to produce electricity for our homes and businesses.
A degree in physics equips one with analytical and problem-solving skills, which are in high demand. These skills also offer a background for understanding an increasingly technological society. Physics degree-holders wind up in a wide range of jobs, many outside of academia. Physics grads often work in the private sector and sometimes at government laboratories. “Financial institutions are always on the lookout for physics majors since they have the perfect blend of strong math skills and the training in how to apply math to modelling real-life problems,” says Jed Macosko.
Look at the evolution of computers: the first computer had a processing speed of 1 MHz, but through understanding quantum physics, the fastest computer to date, can process data at 100 million times faster than the classical computer.
Physics is the study of nature itself. The more we understand nature, the more we can advance as a civilisation.
