Psychology - Science or Religion?

Psychology has adopted the scientific mode. However, from a strictly scientific point of view, it has not been able to meet the requirements of true science.

\mu \left[
\frac{1}{r^2} \frac{\partial}{\partial r}\left(r^2 \frac{\partial u_r}{\partial r}\right) +
\frac{1}{r^2 \sin(\phi)^2} \frac{\partial^2 u_r}{\partial \theta^2} +
\frac{1}{r^2 \sin(\phi)} \frac{\partial}{\partial \phi}\left(\sin(\phi) \frac{\partial u_r}{\partial \phi}\right) -
2 \frac{u_r + \frac{\partial u_{\phi}}{\partial \phi} + u_{\phi} \cot(\phi)}{r^2} +
\frac{2}{r^2 \sin(\phi)} \frac{\partial u_{\theta}}{\partial \theta}
