Historian Barry Adam notes, " Every social movement must choose at some point what to retain and what to reject out of its past.

From a pro-independence supporter's point of view, the movement for Taiwan independence began under Qing rule in the 1680s which led to a well known saying those days, " Every three years an uprising, every five years a rebellion ".

Every number is thought of as a decimal fraction with the initial decimal point omitted, which determines the filing order.

Every non-empty intersection of a 3-sphere with a three-dimensional hyperplane is a 2-sphere ( unless the hyperplane is tangent to the 3-sphere, in which case the intersection is a single point ).

Every point that is expressed in ellipsoidal coordinates can be expressed as an ( Cartesian ) coordinate.

Maxwell Fyfe brought up Raeder's order of 15 October 1939, which read: " Measures which are considered necessary from a military point of view will have to be carried out, even if they are not covered by existing international law ... Every protest from neutral powers will have to be turned down ... The more ruthlessly economic warfare is waged ... the sooner the war will come to an end ".

Every material has a critical angle, at which point light is reflected back internally.

Every point constructible using straightedge and compass may be constructed using compass alone.

( As one later wrote of finally being forced to make an anti-American statement: " I had learned what we all learned over there: Every man has his breaking point.

Every time he throws a point above ten ( or passes ten -- whence the name of the game ), the banker must double the player's stakes and the stakes of all those who have risked their money on the same chance.

Every year at breakup, families moved up into the hills from the point.

Every plane that could fly was sent into the air.

Every hyperbola is congruent to the origin-centered East-West opening hyperbola sharing its same eccentricity ε ( its shape, or degree of " spread "), and is also congruent to the origin-centered North-South opening hyperbola with identical eccentricity ε — that is, it can be rotated so that it opens in the desired direction and can be translated ( rigidly moved in the plane ) so that it is centered at the origin.

Every atom across this plane has an individual set of emission cones .</ p > < p > Drawing the billions of overlapping cones is impossible, so this is a simplified diagram showing the extents of all the emission cones combined.

Every vibrating object tends to maintain its plane of vibration if its support is rotated, a result of Newton's first law.

Every immersed curve in the plane admits two possible orientations.

Every outerplanar graph can be represented as an intersection graph of axis-aligned rectangles in the plane, so outerplanar graphs have boxicity at most two.

Every improper rotation of three-dimensional Euclidean space is rotation followed by a reflection in a plane through the origin.

Every smooth surface S has a unique affine plane tangent to it at each point.

* Every triangle group T is a discrete subgroup of the isometry group of the sphere ( when T is finite ), the Euclidean plane ( when T has a Z + Z subgroup of finite index ), or the hyperbolic plane.

Every minimal projective ruled surface other than the projective plane is the projective bundle of a 2-dimensional vector bundle over some curve.

Every plane travelling to and from Europe or North America must talk to either or both of these air traffic controls ( ATC ).

Every planar graph has a flat and linkless embedding: simply embed the graph into a plane and embed the plane into space.

Every detail of these patterns acts as a consistent portal to a different kingdom inside the plane, which itself comprises many separate realms.

Every algebraic plane curve has a degree, which can be defined, in case of an algebraically closed field, as number of intersections of the curve with a generic line.

Every detail of these patterns acts as a consistent portal to a different kingdom inside the plane, which itself comprises many separate realms.

Every set of points in the plane, and the lines connecting them, may be abstracted as the elements and flats of a rank-3 oriented matroid.

Every second-order linear ODE on the extended complex plane with at most four regular singular points, such as the Lamé equation or the hypergeometric differential equation, can be transformed into this equation by a change of variable.

Every plane B that is completely orthogonalTwo flat subspaces S < sub > 1 </ sub > and S < sub > 2 </ sub > of dimensions M and N of a Euclidean space S of at least M + N dimensions are called completely orthogonal if every line in S1 is orthogonal to every line in S2.

Every planar graph has an algebraic dual, which is in general not unique ( any dual defined by a plane embedding will do ).
