Respective characteristics and styles of the achievements attained by the master physicians: Dirac and Heisenberg, have been discussed in the history of the top three physic achievements in 19 th century: thermodynamics, electromagnetics and statistic dynamics.

In the times so called golden years of physics, Heisenberg, Jordan, Pauli, Dirac, and schroedinger played outstanding parts, but Born, Bohr, and Sommerfeld, men of riper age, made major contributions to quantum mechanics, yet they must be regarded as the foremost teachers of that pe.

Thermal entanglement in the two-qubit Heisenberg model;

It is seen that the model reduces to the Heisenberg model for isolate magnetical material and that it has the united mathmatical treatment with var.

Critical temperatures of anisotropic Heisenberg model are calculated by variational-cumulant expansion.

By using the method of Heisenberg picture,this paper makes an analytical research on the probability of onedimensional harmonic oscillator perturbated with weak electric field within △t time in all its states,and obtains the exact results.

Werner Heisenberg is one of the creative scientists in the twentieth century.
