It seems like you're referring to Nikola Tesla, but it's important to clarify that
Nikola Tesla isn't typically referred to as the "father of physics." While he made groundbreaking contributions to science and engineering—especially in electricity, magnetism, and wireless communication—he's most famous for his work in
electrical engineering rather than the broad field of physics.
The title "father of modern physics" is more often associated with
Albert Einstein, due to his revolutionary theories like the theory of relativity.
However, if you're asking about the "father of physics" in the general sense, many people would consider
Isaac Newton, due to his foundational contributions with his laws of motion and universal gravitation, which laid the groundwork for classical physics.
Tesla, on the other hand, was an inventor and electrical engineer, widely admired for his innovations in alternating current (AC) electrical systems, the Tesla coil, and wireless transmission of energy. His contributions were more technical and engineering-focused, rather than theoretical physics.
