Figure 1: Evolution of the thickness of 2D superconductors since 1980. In this Review, we survey the recent developments in the field of 2D superconductivity. We first summarize the history of 2D ...

(In contrast a scalar quantity has magnitude only - eg, the numbers 1, 2, 3, 4...) This arrow represents a vector. The direction is given by the arrow, while the ...

One of the most important topics taught at the start of introductory physics is the idea of vectors. Students really need proficiency with them if they are to use force and momentum. Just about every ...

Vectors are added ‘nose to tail’ as shown below. The addition of the vectors is the line from the starting point to the finishing point. Triangles ABC and XYZ are equilateral. X is the midpoint of AB, ...
