Opinia (wypadkowa) dla P. = -2
Frank Szmulowicz, Ph. D. Apr 20, 2014:
I agree that torsion and rotation are not the same.
Frank Szmulowicz, Ph. D. Apr 20, 2014:
In solid mechanics, torsion is the twisting of an object due to an applied torque. It is expressed in newton metres (N·m) or foot-pound force (ft·lbf). In sections perpendicular to the torque axis, the resultant shear stress in this section is perpendicular to the radius.

In the elementary differential geometry of curves in three dimensions, the torsion of a curve measures how sharply it is twisting out of the plane of curvature.

The context does NOT CONCERN molecules, molecular bonds, cardiac motion, diffraction methods, main clutch of a transmission, simulated annealing, etc.

rotation

The text speaks about basic COORDINATE TRANSFORMATIONS which are translation, rotation, and scaling.

skręcenie can be translated as rotation as well as twist and torsion, but here the context suggests rotation. For example,
rotation of plane of polarization of light = skręcenie płaszczyzny polaryzacji światła

Dziękuję Jacku. http://www.kartki.pl/pl/showCard/wesolych-swiat-wielkanocnyc...
disagree Polangmar : Skręcenie to nie to samo co obrót - gdyby autorowi chodziło o obrót, użyłby po prostu tego słowa.

Skręcenie is often translated as ROTATION (see rotation of plane of polarization of light = skręcenie płaszczyzny polaryzacji światła), Torsion is something that a rigid body undergoes in mechanics. The translation must go with the topic.

Polish term (edited): skręcenie

torsion

Bez "parametrów" (w tekście nie ma terminu "skręcenie parametrów", bo to nie parametry są skręcane).

Peer comment(s):

disagree Frank Szmulowicz, Ph. D. : Torsion is a complex geometrical concept in very specialized contexts. Torsion or twist is a complex geometrical transformation that does not fit the context, which speaks of such simple coordinate transformations as shift and scale change//WRONG CONTEXT.

Zgadza się: tu mamy właśnie specjalistyczny kontekst, w którym użyto tego złożonego geometrycznego pojęcia - a tu potwierdzenia, że "torsion" i "rotation" to nie to samo: http://tinyurl.com/mdy6amo I nie poprawiamy oryginału gdy jest prawidłowy.
