Hi, I've been breaking my head on the matrix form of the lorentz transformation between one set of coordinates in one inertial frame (t,x^1,x^2,x^3) and what those coordinates will be in another inertial frame (t',x'^2,x'^2,x'^3).
Now I understand that if have a set of coordinates in one...
Homework Statement
In laser physics a common approximation for the time-energy uncertainty is given by.
\Delta \omega \cdot \tau \geq \approx 2 \pi
The problem is to use the Energy-Time Uncertainty relationship to derive a more exact answer than this.
