In 1865, James Clerk Maxwell formulated the theory of electromagnetism, a groundbreaking achievement that unified the previously separate fields of electricity and magnetism. This theory laid the foundation for modern physics and engineering, influencing technologies such as radio, television, and electric power generation. Maxwell's equations, which describe how electric and magnetic fields interact, are considered one of the cornerstones of classical physics.

Maxwell's work on electromagnetism not only influenced the scientific community but also resonated with poets like Tennyson and Whitman, who explored themes of unity and complexity in nature. This interplay between science and poetry fostered a deeper appreciation for the interconnectedness of all forces, both seen and unseen.
