... 30. When the vectors are aligned in the same direction, their maximum value is 9 units. When the vectors oppose each other their minimum value is 1 unit. When the vectors are aligned at some angle to each other, their resultant would have a value between 9 units and 1 unit. ...

Condition estimation and scaling
... To make matters worse, multiplying by the explicit inverse of a matrix is not a backward stable algorithm. Even if we could compute A−1 essentially exactly, only committing rounding errors when storing the entries and when performing matrix-vector multiplication, we would find fl(A−1 b) = (A−1 + F ) ...

Relativistic Mass and Virtual Objects
... It causes that there are possible the creations of virtual electron-positron pairs. Spin of the Einstein-spacetime components is unitary so spins of the electron and positron in a pair are parallel. Since mean mass density of a pair is a little higher than the mean mass density of the Einstein space ...
