### Heisenberg Equation

In the solution manual, the formula deltax= 1/2(h bar/m*deltav) is used. The book solution manual states that h bar is 1.054*10^-34J. My question is how is this derived and is this a constant?

1/2 h bar is the same as h/4pi. If you do the calculations, you'll get that they both equal 5.25x10-35.

No, h bar is not a constant it is just shorthand for pi/2.
