Last video, we used the fact that √2 = ζ + ζ⁻¹, for ζ an 8th root of unity, to tell us about the decomposition of rational primes in Z[√2]. In this video, we see that it is also possible to write √q as a sum of roots of unity for all odd primes q: in fact, we write down an explicit element τ whose square is ±q.
