By the non-zero winding rule, the ray is intersected in a clockwise direction twice, each contributing -1 to the winding score: because the total, -2, is not zero, P is concluded to be 'inside' the curve. In two-dimensional computer graphics, the non-zero winding rule is a means of determining whether a given point falls
This equal area rule can also be derived by making use of the Helmholtz free energy. [24] In any event the Maxwell construction derives from the Gibbs condition of material equilibrium. However, even though g f = g g {\displaystyle g_{f}=g_{\text{g}}} is more fundamental it is more abstract than the equal area rule, which is understood ...
Feynman diagrams are graphs that represent the interaction of particles rather than the physical position of the particle during a scattering process. They are not the same as spacetime diagrams and bubble chamber images even though they all describe particle scattering. Unlike a bubble chamber picture, only the sum of all relevant Feynman ...
The last rule takes into account the effect of dividing by ~ []. The Minkowski-space Feynman rules are similar, except that each vertex is represented by − i λ {\displaystyle -i\lambda } , while each internal line is represented by a factor i /( q 2 - m 2 + i ε ), where the ε term represents the small Wick rotation needed to make the ...
Bubble diagrams, which result in the RPA when summed up. Solid lines stand for interacting or non-interacting Green's functions , dashed lines for two-particle interactions. The random phase approximation ( RPA ) is an approximation method in condensed matter physics and nuclear physics .
Alcubierre interpreted his "warp bubble" in terms of a contraction of space ahead of the bubble and an expansion behind, but this interpretation could be misleading, [18] since the contraction and expansion actually refer to the relative motion of nearby members of the family of ADM observers.

A bubble chart is a type of chart that displays three dimensions of data. Each entity with its triplet ( v 1 , v 2 , v 3 ) of associated data is plotted as a disk that expresses two of the v i values through the disk's xy location and the third through its size.
