Famous quotes by Physicists

"I believe the anthropogenic effect for climate change is still only one of the hypotheses to explain the variability of climate"

Kanya Kusano, Physicist

"I entered the Physics Department in 1950, receiving a Master's degree in 1953 and a Ph.D. in 1956. It is difficult to convey the sense of excitement that pervaded the Department at that time"

Jerome Isaac Friedman, Physicist

"Our family was very fond of the University of Iowa. We thought it was a good place to go"

James Van Allen, Physicist

"Strict conservation of energy in the elementary process had thus been confirmed also by a negative experiment"

Walther Bothe, Physicist

"From a consideration of the immense volume of newly discovered facts in the field of physics, especially atomic physics, in recent years, it might well appear to the layman that the main problems were already solved and that only more detailed work was necessary"

Victor Francis Hess, Physicist

"The material particle nature of primary cosmic radiation has been confirmed, although the processes turned out to be extraordinarily more complicated than we had assumed"

Walther Bothe, Physicist

"The Laboratory for Radioactivity consisted of only two rooms at the time; at a later date, when tests of radioactive substances became more extensive, it expanded into four rooms"

Walther Bothe, Physicist

"On what can we now place our hopes of solving the many riddles which still exist as to the origin and composition of cosmic rays? It must be emphasized here, above all, that to attain really decisive progress, greater funds must be made available"

Victor Francis Hess, Physicist

"It may well be said that the answer to the question: Of what do the cosmic rays in fact consist before they produce their familiar secondary radiation phenomena in the earth's atmosphere? Can only be obtained from numerous measurements in the stratosphere"

Victor Francis Hess, Physicist

"Since that time I have had continuous contact with the persons who were completely unknown to me, except that I knew they would hand whatever information I gave them to the Russian authorities"

Klaus Fuchs, Physicist

"I was ready to accept the philosophy that the Party is right, and that in the coming struggle, you could not permit yourself any doubts, after the Party had made a decision"

Klaus Fuchs, Physicist

"With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change in the structure and change in the spectra of chemical atoms"

Johannes Stark, Physicist

"Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does the individuality of the atoms of different elements consist?"

Johannes Stark, Physicist

"Shortly afterwards my father told me that he might be going into the Eastern Zone of Germany. At that time my own mind was closer to his than it had ever been before, because he also believed that they are at least trying to build a new world"

Klaus Fuchs, Physicist

"Finally, Germany's attack on Russia seemed to confirm that Russia was not shirking and was prepared to carry out a foreign policy with the risk of war with Germany"

Klaus Fuchs, Physicist

"Before I joined the project most of the English people with whom I had made personal contacts were left wing and affected to some degree or other by the same kind of philosophy"

Klaus Fuchs, Physicist

"We can, in fact, first place the beam of rays of moving positive atomic ions in a plane perpendicular to the axis in which we see the spectral lines emitted by them"

Johannes Stark, Physicist

"If the experimental physicist has already done a great deal of work in this field, nevertheless, the theoretical physicist has still hardly begun to evaluate the experimental material which may lead him to conclusions about the structure of the atom"

Johannes Stark, Physicist

"An external electric field, meeting it and passing through it, affects the negative as much as the positive quanta of the atom, and pushes the former to one side, and the latter in the other direction"

Johannes Stark, Physicist

"A beam of luminous hydrogen canal rays has, owing to its velocity, exactly the same direction as that of the electric field in which it may be made to move"

Johannes Stark, Physicist

"The last time when I handed over information was in February or March 1949"

Klaus Fuchs, Physicist

"I was in the underground until I left Germany"

Klaus Fuchs, Physicist

"The discovery of various phenomena has led to a recognition of the fact that the chemical atom is an individual which again is itself made up of several units into a self-contained whole"

Johannes Stark, Physicist

"Rossi was the first to describe another system working with valves in parallel; it has the advantage that it can easily be extended to coincidences between more than two events, and is therefore predominantly used today"

Walther Bothe, Physicist

"During this time I had the singular good fortune of being able to discuss the problem constantly with Einstein. Some experiments done at Einstein's suggestion yielded no decisively new result"

Walther Bothe, Physicist

"I was a student in Germany when Hitler came to power"

Klaus Fuchs, Physicist

"I think, the one thing that most stands out is that my father always did what he believed to be the right thing to do, and he always told us that we had to go our own way, even if he disagreed"

Klaus Fuchs, Physicist

"I had, therefore, no hesitation in giving all the information I had, even though occasionally I tried to concentrate mainly on giving information about the results of my own work"

Klaus Fuchs, Physicist

"We have learnt through experience that when an electrical ray strikes the surface of an atom, an electron, and in some circumstances a second and even a third electron, can be detached"

Johannes Stark, Physicist

"The removal of an electron from the surface of an atom - that is, the ionization of the atom - means a fundamental structural change in its surface layer"

Johannes Stark, Physicist
