,Galois’s Great Theorem,We prove the converse of Theorem 74: Solvability of the Galois group of .(.) ∈.[.], where . is a field of characteristic 0, implies .(.) is solvable by radicals. We begin with some lemmas; the first one has a quaint name signifying its use as a device to get around the possible absence of roots of unity in the ground field.

Plants as Bioindicators of Air Pollutantsscribe symmetry. The Greek roots of the word . mean, roughly, measuring at the same time. In ordinary parlance, there are at least two meanings of the word, both involving an arrangement of parts somehow balanced with respect to the whole and to each other. One of these meanings attributes an aesthe

Historical Development of Air Transport,ll be relevant whether or not . contains such roots of unity. Note that R, for example, contains the square roots of unity, namely, 1 and — 1, but it contains no higher roots of unity (other than 1) because they are all complex.

Plants as Bioindicators of Air Pollutantstic quality to the arrangement, implying that symmetry is harmonious and well-proportioned. This usage is common in many discussions of art, and one sees it in some mathematics books as well (e.g., Weyl’s .). Here, however, we focus on arrangements without considering, for example, whether a square is more pleasing to the eye than a rectangle.
