- name capture — (reduction) In beta reduction, when a term containing a free occurrence of a variable v is substituted into another term where v is bound the free v becomes spuriously bound or "captured". E.g. (\ x . \ y . x y) y --> \ y . y y (WRONG) This problem arises because two distinct variables have the same name. The most common solution is to rename the bound variable using alpha conversion: (\ x . \ y' . x y') y --> \ y' . y y' Another solution is to use de Bruijn notation. Note that the argument expression, y, contained a free variable. The whole expression above must therefore be notionally contained within the body of some lambda abstraction which binds y. If we never reduce inside the body of a lambda abstraction (as in reduction to weak head normal form) then name capture cannot occur.
- nanocomputer — (architecture) /nan'oh-k*m-pyoo'tr/ A computer with molecular-sized switching elements. Designs for mechanical nanocomputers which use single-molecule sliding rods for their logic have been proposed. The controller for a nanobot would be a nanocomputer. Some nanocomputers can also be called quantum computers because quantum physics plays a major role in calculations. Richard P. Feynman is still cited today for his work in this area.

- not-a-number — (mathematics) (NaN) An IEEE floating point representation for the result of a numerical operation which cannot return a valid number value. A NaN can result from multiplying an infinity by a zero, or from subtracting one infinity from another [what else?]. NaN is encoded as a special bit pattern [what pattern?] which would otherwise represent a floating-point number. It is used to signal error returns where other mechanisms are not convenient, e.g. a hardware floating-point unit and to allow errors to propagate through a calculation. Similar bit patterns represent positive and negative overflow and underflow and the positive and negative infinities resulting from division by zero.
