"In the absence of a magnetic field the period of all these oscillations is the same. But as soon as the electron is exposed to the effect of a magnetic field, its motion changes."

"Freedom in general may be defined as the absence of obstacles to the realization of desires."

"God's absence in the carnage is due to one single rather unnerving fact; that at some time past He honored our request that He leave. And if we are not brutally honest with ourselves regarding that choice, it is we ourselves who have set the stage for the next tragedy."

"The system adopted in the Latin American instrument proves that, although no state can obligate another to join such a zone, neither can one prevent others wishing to do so from adhering to a regime of total absence of nuclear weapons within their own territories."

"In Heaven all the interesting people are missing."

"Barbarism is the absence of standards to which appeal can be made."

"My dear, the duty that devolved wholly on you in my absence of guiding and expanding the minds of our dear children is a laborious one and a responsible one."

"Moreover, photography has made it possible to fix these images and now provides us with a permanent record of each observed spectrum, which can be measured out at any time."

"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."

"Had we really succeeded therefore in altering the period of vibration, which Maxwell, as I have just noted, held to be impossible? Or was there some disturbing circumstances from one or more factors which distorted the result?"

"I should point out, however, that at first some difficulty was experienced in observing the phenomena predicted by the theory, owing to the extreme smallness of the variations in the period of oscillation."

"It was not simply out of a spirit of contradiction that I exposed a light source to magnetic forces. The idea came to me during an investigation of the effect discovered by Kerr on light reflected by magnetic mirrors."

"Nature gives us all, including Prof. Lorentz, surprises. It was very quickly found that there are many exceptions to the rule of splitting of the lines only into triplets."

"I count myself fortunate to be able to contribute to this work; and the great interest which the Royal Swedish Academy of Sciences has shown in my work and the recognition that it has paid to my past successes, convince me that I am not on the wrong track."

"Now if this electron is displaced from its equilibrium position, a force that is directly proportional to the displacement restores it like a pendulum to its position of rest."

"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."
