The simple physical act of joining two machines has, of course, a counterpart in the equations, shown more simply in the canonical than in the group equations. One could, of course, simply write down equations in all the variables and then simply let some parameter a have one value when the parts are joined and another when they are separated. This method, however, gives no insight into the real events in ' joining ' two systems. A better method is to equate para- meters in one system to variables in the other. When this is 229 q
