Uncertainty principal, Werner Heisenberg (1901-1976)

Mar 21, 1927

The Uncertainty principal says that the position and the velocity of an object cannot both be measured exactly at the same time even in theory. The very concepts of exact positions and exact velocity together, in fact, have no meaning of nature. What this tells us is that there is a limit to what we can know about quantum particles, the most we can hope for is to calculate where things are and how they will act. Heisenberg found a problem in the way that the basic physical properties could be

Theory of ferromagnetism, Werner Heisenberg (1901-1976)

1928

Starting around the year 600 BC magnetism has been a subject that has interested philosophers and physicist with how to figure out how it works and what creates that magnetism. Fast forward to the 1920 and the beginning of quantum mechanics did we start to understand the physical aspect of the spin properties of an electron. Heisenberg would solve the mystery of ferromagnetism using the concept of spin plus exclusion formulated by Wolfgang Pauli. which states "That two electrons with the same

Scattering matrix,Werner Heisenberg (1901-1976)

1943

Scattering matrix or S matrix was introduced in a series of papers in 1943 and 1944. Those papers were on the observable quantities in the theory of elementary particles. These papers were wrote Just a few years after the introduction of quantum mechanics. In believing that the quantum field theory of elementary particles requires a major change at higher energies, because of the possible existence of a universal length. When Heisenberg first wrote these papers, he viewed the matrix as a

Elementary particle, Werner Heisenberg (1901-1976)

Dec 23, 1955

In December of 1955 Werner Heisenberg would write an article about the theory of the elementary particles. He would state "It is obvious that at the present state of our knowledge it would be hopeless to try and find the correct theory of the elementary particles." and during that time they only had good picture of what they are. He did expect that idea though experiments to change over the next 5 to 10 years. What did they know at that time about elementary particles? There were a great
