"Understanding is much better than Learning"

Try to get the explanations of these questions while going through the readings:

​

1. Comment

   1. H20 is a mineral.

   2. Mineral formed by organism.
       

2. Explanation of the Science behind the Fluorescence and Phosphorescence both theoretically and mathematically.
    

3. Discussion on the reason behind the Chatoyancy and Asterism. Study of some specimens showing these properties.
    

4. Imagination and drawings of the cleavage planes direction in Octahedral (4 plane) and Dodecahedral (6 plane) crystals.
    

5. Measurement of specific Gravities of some samples.
    

6. Reason behind having some Minerals which show Piezoelectricity and Pyro-electricity?
    

7. Differences between structure of Olivine series and Spinel structure as both has AB2O4.
    

8. Detailed insights of concept of radius ratio.
    

9. Understanding of the significance of Lattice concept in Crystallography?
    

10. Story behind the “Steno’s law of the Constancy of Interfacial angle”.
     

11. Understanding of the relation between Isometric Cube Crystal and its Isometric forms (Octahedron, Tetrahedron, Hex-octahedron etc.)
     

12. Major Scientific reason behind having only 6 crystal system or 32 space groups?

    There is no mention of ‘3/m’ in space group chart?
     

13. 322 is not a possible space group?
     

14. Hexagonal Bravais-Miller index is (h k i l). The sum of first three digit is always zero?
     

15. Understanding of the concept of General and Special form that is needed to define a mineral.
