4. Quantum Spin Dynamics and the MRI

There are no short cuts to science and development. The quantum nature of matter is learnt through the basics of the quantum mechanics (QM). Quantum science education unfortunately at present does not form part of the curriculum at secondary level of education. It is the situation all over the world. Learning QM is no more difficult than learning the Newtonian Mechanics (NM). In NM we are dealing with large rigid bodies; the dynamics is macroscopic in nature and the object’s position, velocity, acceleration etc. can be accurately determined. Further in NM the large objects e.g. planets do not react chemically. The only interaction they have is through the gravitational forces and is very weak. It has little affect on the human life visually to any degree of significance known. Planets in our solar system interact through gravitational forces among each other and with the sun in space and time and keep their dynamics of motion in equilibrium. The forces which make them move and remain in balance are well understood. The motion of the moon under the influence of gravitational forces around earth does however control to some extent the tidal effects and probably the climate on earth as well.
