Niels Bohr (Niels Henrick Abel Bohr)

Niels Bohr was a Danish physicist who made groundbreaking contributions to understanding atomic structure and quantum theory. He proposed that electrons orbit the nucleus of an atom in specific, quantized energy levels, much like rungs on a ladder. When electrons jump between these levels, they absorb or emit precise amounts of energy in the form of light. Bohr’s model helped explain atomic spectra and laid the foundation for modern quantum mechanics, influencing how scientists understand matter at its most fundamental level. His work was crucial in advancing both physics and our understanding of the universe.
