"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."

"The fundamental laws necessary for the mathematical treatment of a large part of physics and the whole of chemistry are thus completely known, and the difficulty lies only in the fact that application of these laws leads to equations that are too complex to be solved."
"There are no insuperable constitutional difficulties."
"I've always had difficulties with female characters."
"It does not do to use it with forms whose origin is intimately bound up with a specific material simply because no technical difficulties stand in the way."
"It seems that the greatest difficulty is to find the end. Don't try to find it, it's there already."
"I sometimes suspect that half our difficulties are imaginary and that if we kept quiet about them they would disappear."
"When 25 percent of the population believe the President should be impeached and 51 percent of the population believe in UFOs, you may or may not need a new President, but you definitely need a new population."
"Sometimes I write notes that I have difficulty singing."
"A man who dreads trials and difficulties cannot become a revolutionary. If he is to become a revolutionary with an indomitable fighting spirit, he must be tempered in the arduous struggle from his youth. As the saying goes, early training means more than late earning."
"Because of the tension and difficulty, I remember trying to do the silliest things when we weren't rolling cameras, anything to lift the spirits. But once on set, it was important to have full concentration."

"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."
"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."
"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."
"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?"
"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."
"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."
"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."
"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."
