Bohr, Niels

Niels Bohr was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory. He proposed that electrons orbit atoms' nuclei in specific, quantized energy levels, which explained how atoms absorb and emit light. Bohr's model helped bridge classical physics and emerging quantum ideas, influencing the development of modern physics. His work also contributed to understanding atomic stability and laid the groundwork for later advances in quantum mechanics.
