Due or meaning no!

I love you

a is always acceleration? This bit throws me off, because how would one have a value for acceleration before finding the dispersion relation? (question partains more to the last video) Thank you btw, this series is incredible!!!

“a” in this video is referring to the distance between adjacent sites in the 1d lattice.
