Only a week before the application deadline, I came across Hamilton and it just seemed like the perfect fit for me; I fell in love with Hamilton's emphasis on writing and speaking, the freedom that the open curriculum offered, and Hamilton's Outdoor Leadership Center. Hamiltonian (4), and N(t) = h 0(t)j 0(t)iis the norm of the wave function, while ˚(x) and (x) are the regular LL elds, de ned in terms of the b q operators [31,39]. It also took the voyager spacecraft to the far reaches of the solar system. There is an alternative representation of static technological opportunities that is more congenial to dynamic analysis, that is, the representation of the technology by its Hamiltonian function. 9.9 Stock Pollutants: Local Dynamics in the Neighborhood of the Steady State222 9.10 Dynamics in the Neighborhood of a Steady State: General Remarks227 9.11 Stock Pollutants: Comparative Statics and Dynamics .
