     After this lecture you will be able to:
 
-    - formulate equations of motion for electrons or phonons in 1D, for systems with multiple degrees of freedom per unit cell.
+    - formulate equations of motion for electrons or phonons in 1D, with multiple degrees of freedom per unit cell.
     - solve these equations to arrive at the dispersion relation.
     - derive the group velocity, effective mass, and density of states.
     - explain what happens with the band structure when the periodicity of the lattice is increased or reduced.
