In fact, the mathematics that describe both systems are formally equivalent.
String nets can support waves which Xiao-Gang Wen says are formally equivalent to photons.
White holes aren't so different to black holes (in fact Hawking argues that they are formally equivalent).
The problem of finding a reaction centre in a protein matrix is formally equivalent to many other problems in computing.
McGuire and co say the problem of Sudoku grid checking is formally equivalent to problems in gene expression analysis and in computer network and software testing.
Although all have been called into some question empirically, the least plausible and least studied is the property that formally equivalent gambles are treated as indifferent in preference.
In rank-dependent cases, which arise from a restricted assumption about formally equivalent gambles, the weights depend on the rank position of the corresponding consequence.
Moreover, we show that this simplified version of the TDDM is formally equivalent to Scalar Expectancy Theory (SET) under stationary behaviours, the most prominent theory of interval timing.
The present study offers a start point for systematic comparisons between vertebrate and invertebrate species in formally equivalent tasks that produce univocal demonstrations of the blocking effect.
The paper also shows, more generally, that the design of a frequency-shaped sliding surface is formally equivalent to a feedback feedforward compensation problem.
The present research investigated the blocking effect in three different species, rats, humans and snails in formally equivalent tasks using a within-subjects design.
