This force is used in the formal definition of the ampere, which states that it is " the constant current that will produce an attractive force of 2 × 10 < sup >– 7 </ sup > newton per metre of length between two straight, parallel conductors of infinite length and negligible circular cross section placed one metre apart in a vacuum ".

The stalks grow in tight, straight, parallel bunches, and are typically marketed fresh that way, without roots and just a little green leaf remaining.

The = symbol was invented by Robert Recorde ( 1510 – 1558 ), who considered that nothing could be more equal than parallel straight lines with the same length.

# The parallel postulate: " That, if a straight line falling on two straight lines make the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which are the angles less than the two right angles.

# If two straight lines in a plane are crossed by another straight line ( called the transversal ), and the interior angles between the two lines and the transversal lying on one side of the transversal add up to less than two right angles, then on that side of the transversal, the two lines extended will intersect ( also called the parallel postulate ).

Since the vectors are collinear ( parallel, and lie on the same line )-only the magnitudes of the vectors are necessary, hence non-bold letters are used for magnitudes, and because the motion is along a straight line, the problem effectively reduces from three dimensions to one.

South Indian blades are often made broad at the hilt and taper in straight lines to the point, and elaborately ribbed by grooves parallel to the edges.

It corresponds to a tetrahedron where non-intersecting edges are considered " parallel ", or a square where not only opposite sides, but also diagonals are considered " parallel ".

Some of Pickover ’ s later books often discussed " science at the edges ," including such topics as Many-worlds interpretation | parallel universes, quantum immortality, alien life, and elf-like beings seen by some people who use dimethyltryptamine.

The introduction of composite skis, metal edges, releasable clamping bindings, and stiff plastic boots combined to allow parallel turns even on beginner equipment.

; Tangential continuity ( G1 ): requires the end vectors of the curves or surfaces to be parallel, ruling out sharp edges.

* Orthogonal layout methods, which allow the edges of the graph to run horizontally or vertically, parallel to the coordinate axes of the layout.

* Tapered figure skating blades have a design which causes them to be thicker at the front near the toepicks and thinner at the tail of the blade ; therefore, the edges are not parallel.

In this variation of graph minor theory, a graph is always simplified after any edge contraction to eliminate its self-loops and multiple edges .< ref > is inconsistent about whether to allow self-loops and multiple adjacencies: he writes on p. 76 that " parallel edges and loops are allowed " but on p. 77 he states that " a graph is a forest if and only if it does not contain the triangle K < sub > 3 </ sub > as a minor ", true only for simple graphs .</ ref >

) is idealized by assuming that it is so thin that it can be regarded as a curve and that it is so flexible any force of tension exerted by the chain is parallel to the chain.

Because this internal 1571 does not have an unused 8-bit input / output port on any chip, unlike most other Commodore drives, it is not possible to install a parallel cable in this drive, such as that used by SpeedDOS, Dolphin DOS and some other fast third-party Commodore DOS replacements.

If we draw an ellipse twice as long as it is wide, and draw the circle centered at the ellipse's center with diameter equal to the ellipse's longer axis, then on any line parallel to the shorter axis the length within the circle is twice the length within the ellipse.

Vermont historian Samuel Williams called it " an act which for its savage barbarity is probably without parallel in the legislation of any civilized country ".

Taken as a physical description of space, postulate 2 ( extending a line ) asserts that space does not have holes or boundaries ( in other words, space is homogeneous and unbounded ); postulate 4 ( equality of right angles ) says that space is isotropic and figures may be moved to any location while maintaining congruence ; and postulate 5 ( the parallel postulate ) that space is flat ( has no intrinsic curvature ).

* If there is no data dependency between two pure expressions, then their order can be reversed, or they can be performed in parallel and they cannot interfere with one another ( in other terms, the evaluation of any pure expression is thread-safe ).

This scheme attempts to grasp the heterogeneity of components involved in the production of subjectivity, as Guattari understands it, which include both signifying semiotic components as well as " a-signifying semiological dimensions " ( which work " in parallel or independently of " any signifiying function that they may have ).

The Author continued for about three hours in a profound sleep, at least of the external senses, during which time he has the most vivid confidence, that he could not have composed less than from two to three hundred lines ; if that indeed can be called composition in which all the images rose up before him as things, with a parallel production of the correspondent expressions, without any sensation or consciousness of effort.

" He argues this " implies that any conceivable parallel universe theory can be described at Level IV " and " subsumes all other ensembles, therefore brings closure to the hierarchy of multiverses, and there cannot be say a Level V ."

That is a parallel computer with a central pool of memory, and any processor can access any bit of memory in constant time.

then there is a point ( 0, f )— the focus, F — such that any point P on the parabola will be equidistant from both the focus and the linear directrix, L. The linear directrix is a line perpendicular to the axis of symmetry of the parabola ( in this case parallel to the x axis ) and passes through the point ( 0 ,- f ).

Ramism could not exert any influence on the established Catholic schools and universities, which remained loyal to Scholasticism, or on the new Catholic schools and universities founded by members of the religious orders known as the Society of Jesus or the Oratorians, as can be seen in the Jesuit curriculum ( in use right up to the 19th century, across the Christian world ) known as the Ratio Studiorum ( that Claude Pavur, S. J., has recently translated into English, with the Latin text in the parallel column on each page ( St. Louis: Institute of Jesuit Sources, 2005 )).
