What was Modern about Modern Physics? – Page 6

Similarly, in order to understand the key concepts of modern physics, one must abandon what they already knew or relied on to spaceunderstand nature. For example, to develop and understand the general theory of relativity, one must approach the role of space-time differently. One must forget that space-time is a stationary factor in the background that does not cause any effect. Rather, one must view space-time as having the potential to be transformed by neighbouring objects with gravitational force. “… In collaboration with Grossmann, Einstein developed a tensor theory of gravitation in which space-time was no longer seen as an inert background of physical events, but it was itself subject to changes due to the presence of gravitating bodies… ” Einstein, with Grossmann who helped formulate the mathematical equations, developed the general theory of relativity, however, he was forced to view space-time from an unconventional angel. Without the changes in traditional views, it is not possible to understand in depth the concepts explained by the general theory of relativity. When Einstein published his refined version of the general theory of relativity, very few physicists were able to understand it because of its complexity and new mathematical formulations.

Twentieth century physics, appropriately crowned modern physics, has a distinct approach to describe the natural world, which follows in the footsteps of modernity. Modern physics resonates with the modernism evident in the twentieth century society. Areas of research, such as quantum mechanics and relativity, were one of the most radical and controversial offspring of modern physics, which laid the foundation on which present day physics is established.
