What wouldn't we have if James Maxwell would not have existed?

Answer 1

If James Clerk Maxwell had not existed, we would likely lack a comprehensive understanding of electromagnetism, as his formulation of Maxwell's equations unified electricity, magnetism, and optics into a single theoretical framework. This would have delayed advancements in various fields, including electrical engineering, telecommunications, and modern physics. Technologies such as radio, television, and even modern wireless communication might have evolved much more slowly. Additionally, the development of quantum mechanics could have been hindered, as Maxwell's work laid essential groundwork for later scientific discoveries.
