Overview
Modern physics, spanning from the late 19th century to the present, has revolutionized our understanding of the universe, introducing concepts such as relativity, quantum mechanics, and particle physics. The theory of relativity, developed by Albert Einstein in 1905 and 1915, transformed our comprehension of space and time. Quantum mechanics, formulated by Max Planck, Niels Bohr, and Erwin Schrödinger in the early 20th century, revealed the probabilistic nature of physical phenomena at the atomic and subatomic level. The discovery of particles like the Higgs boson in 2012 and the ongoing research in cosmology have further expanded our knowledge. However, modern physics also faces challenges and controversies, such as the interpretation of quantum mechanics and the search for a unified theory. As research continues, with scientists like Stephen Hawking and Neil deGrasse Tyson contributing to the field, the future of modern physics holds much promise for unraveling the universe's secrets, with potential breakthroughs in areas like quantum computing and gravitational wave astronomy.
