Resonance Zones in Action Space

Resonance Zones in Action Space

The classical and quantum mechanics of isolated, nonlinear resonances in integrable systems with N 2 degrees of freedom is discussed in terms of geometry in the space of action variables. Energy surfaces and frequencies are calculated and graphically presented for invariant tori inside and outside the resonance zone. The quantum mechanical eigenvalues, computed in the semiclassical WKB approxim...

The classical and quantum mechanics of isolated, nonlinear resonances in integrable systems with N ≥ 2 degrees of freedom is discussed in terms of geometry in the space of action variables. Energy surfaces and frequencies are calculated and graphically presented for invariant tori inside and outside the resonance zone.

Pupils, the forgotten partners in education action zones

Education action zones (EAZs) involving local partnerships are one of the government’s policies set up to help raise standards in pupils’ performance and behaviour in areas of economic and social disadvantage. This article explores the nature of these partnerships and the fact that pupils are excluded. It reviews literature on student voice and describes interviews with 139 Year 8 pupils in two...
