Proton mass equals that of a hydrogen atom. Proton is 1840 times heavier than an electron. Proton has a charge of +1.602 × 10-19 coulombs. Proton is a positively charged subatomic entity
Born in 1879 in Germany to Jewish parents. Showed early interest in science and mathematics from age five. Graduated from ETH Zürich in 1900 with physics degree. Worked at Swiss Patent Office from 1903
Quantum mechanics describes matter and light behavior on atomic and subatomic scales. It explains particle-wave interactions and electromagnetic radiation properties. Despite practical success, fundamental problems remain unresolved. Measurement in quantum systems is generally impossible without disturbance
Quantum mechanics studies matter and light behavior at atomic and subatomic scales. It describes properties of particles and their interactions with electromagnetic radiation. Atomic behavior differs from everyday observations but is fundamental to physics
Quantum mechanics studies matter and light behavior at atomic and subatomic scales. It describes properties of particles and their interactions with electromagnetic radiation. Atomic behavior differs from everyday observations but doesn't contradict physics
Born in Vienna on April 25th, 1900, same year as Planck's quantum theory. Studied under Arnold Sommerfeld, who influenced his atomic model research. Published papers on relativity theory from early years
