The Uncertainty Principleĭuring 19 Werner Heisenberg studied a way to study quantum systems. On the other side, if there is no observer, the electron will cause an interference pattern, meaning the electron would have passed through the two slits at the same time, acting as a wave. If an observer or something is monitoring the path of the electron through the slits it will not create interference, meaning they will only pass through the slits. The experiment consists of a wall with two slits with a screen behind. This experiment shows the dual nature of the electron and suggests that observing the particles may affect their behavior. The double-slit experiment is one of the most famous physics experiments. This density is shown by the Electron Cloud Model. Since its exact position cannot be known, the probability of where the electron can be found within the atom is used, this is called probability density. Position and momentum are complementary properties of the electron. In short, you can see the electron as a particle or as a wave, but not both at the same time. You can’t see an electron as a particle and know its exact position, while you can’t know its precise velocity or momentum when it acts as a wave, at the same time. The natural duality of the electron is demonstrated by the de Brogile relation h being plank’s constant. The Electron on the Uncertainty PrincipleĪn electron is a particle, but it also behaves like a wave. Heisenberg and Pauli collaborated together in quantum mechanics. Pauli recommended that he dedicate himself to studying atomic theory, instead of the theory of relativity, since there was a greater field of study. Werner was the leader researcher on the atomic bomb project during World War II.ĭuring his doctorare years, he met Wolfgang Pauli. From 1924 to 1927 he got a scholarship to work with Niels Bohr at the Copenhagen University. Heisenberg was Max Borns assistant in 1923. He was born on December 5 th, 1901 in Wüzburgo and studied at the Munich University. He is best known for formulating the Uncertainty Principle, which was published in 1927, five years later he was awarded the Nobel Prize in physics for the “The creation of quantum mechanics, the use of which has led, among other things, to the discovery of allotropic forms of hydrogen.”. Werner Karl Heisenberg was a German theoretical physicist, who focused his studies on quantum mechanics. This principle tells us about limits and behaviors inside quantum mechanics. The Uncertainty Principle, formulated by Werner Heisenberg, states that we can’t know the exact position and momentum/velocity of a particle at the same time with perfect accuracy the more we know about the photon or electrons speed, the less we know about its position, and vice versa. After reading the article you’ll fully understand the electron duality and the basis of the principle Topics Covered in Other Articles In this article you will learn about one of the fundamental principles on quantum mechanics, the uncertainty principle.
