Why Physics is the king of all sciences or centre of science

1. For a face centred cubic crystal, total number of lattice points contained in a unit cell = (8 x 1/8) + (6 x 1/2) = 4.

2. Packing fraction for a body centred cubic crystal is 0.68. That means matter occupies 68 percent of space in body centred cubic crystal (bcc).

3. For a hexagonal crystal system, a = b ≠ c

Also, α = β = 900

          γ = 1200

It has a one 6-fold rotation axis (characteristic symmetry element).

4. The number of associated lattice for an orthorhombic crystal lattice is 4 (P,C,F,I).

5. The 23 elements of symmetry in cubic crystals are classified into three kinds. They are: (i) Inversion symmetry

        (ii) Rotational symmetry

        (iii) Reflection symmetry

whereas rotational symmetry is also referred to as cylindrical symmetry.
