I will explain how Goodwillie calculus allows for explicit computation of unstable homotopy groups from stable homotopy groups, and how it intertwines with the EHP sequence.  While some of what I say is now known to extend to odd primes, I will focus on the homotopy groups localized at the prime 2.
