(genetics) an organized international scientific endeavour to determine the complete structure of human genetic material (DNA), identify all the genes, and to understand their function

The quotient of a Hilbert space by an equivalence relation which considers a pair of vectors equivalent iff they differ only by a factor which is a complex number.

A form of cylindric equal-area map projection.

plural of projective Hilbert space

plural of complex projective line

(analytic geometry, projective geometry) A complex line (especially, the set of complex numbers regarded as such) endowed with a point at infinity (thus becoming a projective line); (more formally) the set of equivalence classes of ordered pairs (α, β) of complex numbers, not both zero, with respect to the equivalence relation "(α, β) ≡ (λα, λβ) for all nonzero complex λ".

(geometry) A three-dimensional vector space over the field of real numbers in which one-dimensional linear subspaces are considered as “points” and two-dimensional linear subspaces are considered as “lines”. Equivalently, a sphere in which pairs of antipodal points are considered as “points” and great circles are considered as “lines”.

A project that is culmination of an academic course or major. This is typically done at the end of said course or major.

plural of first angle projection

(uncountable) A method of technical drawing where the front view of the object is placed in the third quadrant, the side view is to the right, and the top view is above it. (More common in North America.)
