For an example of an outright wrong article that I just discovered, see ncatlab.org/nlab/show/theory+of+algebraically+closed+fields. The field C(t) where C is the complex number field and t is an indeterminate is obviously not algebraically complete, but the article's definition implies that it is. It is not a typographical error because it is stated twice in totally different but equivalent ways:
> ACF is the countable collection of sentences in the language ℒ[ring] of rings given by: {field axioms}+{(∃x)(a[n]x^n+…+a[0]=0]}, where the tuples a[0..n] range over all finite tuples of integers.
