But to say that verbs have no use is a very interesting idea not unlike lipograms which try to exclude certain vowels: http://www.google.com/search?q=lipograms Linguistics is becoming a very important sub-major for physicists. I would highly recommend Saussure(compare his diachronic and synchronic analysis to Fourier's transform), Sapir-Whorf's "Linguistic Relativity", and Quine's "Translation Indeterminacy". In addition, here is a very kewl perl module: -------------------------------------------------------- "The Quantum::Superpositions module provides a new scalar data structure: the superposition. In a metaphor drawn from quantum mechanics, superpositions store a collection of values by overlaying them in parallel superimposed states within a single scalar variable. Which allows for cool stuff like: use Quantum::Superpositions; if ($x == any($a, $b, $c) { ... } while ($nextval < all(@thresholds) { ... } $max = any(@value) < all(@values); Under the standard interpretation of quantum mechanics, until they are observed, particles exist only as a discontinuous probability function. Under the Cophenhagen Interpretation, this situation is often visualized by imagining the state of an unobserved particle to be a ghostly overlay of all its possible observable states simultaneously. For example, a particle that might be observed in state A, B, or C may be considered to be in a pseudo-state where it is simultaneously in states A, B, and C. Such a particle is said to be in a superposition of states. Research into applying particle superposition in construction of computer hardware is already well advanced. The aim of such research is to develop reliable quantum memories, in which an individual bit is stored as some measurable property of a quantised particle (a qubit). Because the particle can be physically coerced into a superposition of states, it can store bits that are simultaneously 1 and 0. Specific processes based on the interactions of one or more qubits (such as interference, entanglement, or additional superposition) are then be used to construct quantum logic gates. Such gates can in turn be employed to perform logical operations on qubits, allowing logical and mathematical operations to be executed in parallel. Unfortunately, the math required to design and use quantum algorithms on quantum computers is painfully hard. The Quantum::Superpositions module offers another approach, based on the superposition of entire scalar values (rather than individual qubits). " http://search.cpan.org/search?dist=Quantum-Superpositions -------------------------------------------------------- The demos are very interesting, and the html documentation point's out the interesting non-commutivities in using operators on disjuctive and conjunction superpositions. The use of the module forces a different way of thinking (much as does it's native perl language does). Whereas academically we are largely taught to think in terms of one or more serial (logical/causual) threads like a serial or parallel computer cable. This module requires one to think more like a parallel cable that has little or no insulation between it's leads. |
