It is not the possession of truth, but the success which attends the seeking after it, that enriches the seeker and brings happiness to him. – Max Planck
We have no right to assume that any physical laws exist, or if they have existed up until now, that they will continue to exist in a similar manner in the future. – Max Planck
A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it. – Max Planck
