Max Born and the probability of locating a particles position
Max Born is best known for his statistical analysis of how subatomic particles behave. His studies of the wave function led to a reassessment of the original quantum theory by replacing the explanation of electrons as particles with a more accurate mathematical and statistical interpretation of the observed behavior of electrons. His work contributed to the understanding of the nature of quantum mechanics. Born Won the Nobel Prize for Physics in 1954. -
