Investigation may be likened to the long months of pregnancy, and solving a problem to the day of birth. To investigate a problem is, indeed, to solve it. ↗

The atom bomb is a paper tiger which the United States reactionaries use to scare people. It looks terrible, but in fact it isn't. ↗

The cardinal responsibility of leadership is to identify the dominant contradiction at each point of the historical process and to work out a central line to resolve it. ↗

The differences between friends cannot but reinforce their friendship. ↗

We shall heal our wounds, collect our dead and continue fighting. ↗

According to well-known electrodynamic laws, an electron moving in a magnetic field is acted upon by a force which runs perpendicular to the direction of motion of the electron and to the direction of the magnetic field, and whose magnitude is easily determined. ↗

Now all oscillatory movements of such an electron can be conceived of as being split up into force, and two circular oscillations perpendicular to this direction rotating in opposite directions. ↗

On the basis of Lorentz's theory, if we limit ourselves to a single spectral line, it suffices to assume that each atom (or molecule) contains a single moving electron. ↗

The rotation of the polarization plane is extraordinarily small in all gases, thus also in sodium vapour. ↗

We studied the light source in the direction of the magnetic force, we perforated the poles of the magnet; but even in the direction of the magnetic lines of force we found that our result was confirmed. ↗
