The most convincing proof of the conversion of heat into living force [vis viva] has been derived from my experiments with the electro-magnetic engine, a machine composed of magnets and bars of iron set in motion by an electrical battery. I have prov...
A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines. With consistency a great soul has simply nothing to do. He may as well concern himself with his shadow on the wall. Speak what you think ...
My dear nephew was only in his sixth year when I came to be detached from the family circle. But this did not hinder and I from remaining the most affectionate friends, and many a half or whole holiday he was allowed to spend with me, was dedicated t...
Science is the search for the truth--it is not a game in which one tries to beat his opponent, to do harm to others. We need to have the spirit of science in international affairs, to make the conduct of international affairs the effort to find the r...
Physics is the ultimate intellectual adventure, the quest to understand the deepest mysteries of our Universe. Physics doesn’t take something fascinating and make it boring. Rather, it helps us see more clearly, adding to the beauty and wonder of t...
It is a curious thought that the earliest description of the steam-engine in antiquity describes its use for the magic opening of the temple doors, when the priests lit the fires on the altars, to deceive the populace into ascribing to a deity what w...
6.4311 Der Tod ist kein Ereignis des Lebens. Den Tod erlebt man nicht. Wenn man unter Ewigkeit nicht unendliche Zeitdauer, sondern Unzeitlichkeit versteht, dann lebt der ewig, der in der Gegenwart lebt. Unser Leben ist ebenso endlos, wie unser Gesich...
It can even be thought that radium could become very dangerous in criminal hands, and here the question can be raised whether mankind benefits from knowing the secrets of Nature, whether it is ready to profit from it or whether this knowledge will no...
There are those whose views about religion are not very different from my own, but who nevertheless feel that we should try to damp down the conflict, that we should compromise it. … I respect their views and I understand their motives, and I don't...
During the time that gave me an education in the field of immunology, I discovered that he and I were thinking about the serologic problem in very different ways. He would ask, What do these experiments force us to believe about the nature of the wor...
I think a strong claim can be made that the process of scientific discovery may be regarded as a form of art. This is best seen in the theoretical aspects of Physical Science. The mathematical theorist builds up on certain assumptions and according t...
The reason 's physics was so hard for ordinary people to grasp was that he did not use equations. The usual theoretical physics was done since the time of was to begin by writing down some equations and then to work hard calculating solutions of the ...
By the time of the arrival of Islam in the early seventeenth century CE, what we now call the Middle East was divided between the Persian and Byzantine empires. But with the spread of this new religion from Arabia, a powerful empire emerged, and with...
Don't keep forever on the public road,going only where others have gone, and following one after the other like a flock of sheep. Leave the beaten track occasionally and dive into the woods. 'Every time you do so you will be certain to find something...
In the history of science, ever since the famous trial of Galileo, it has repeatedly been claimed that scientific truth cannot be reconciled with the religious interpretation of the world. Although I an now convinced that scientific truth is unassail...
The attitude which the man in the street unconsciously adopts towards science is capricious and varied. At one moment he scorns the scientist for a highbrow, at another anathematizes him for blasphemously undermining his religion; but at the mention ...
Sherman Reilly Duffy of the pre-World War I CHICAGO DAILY JOURNAL once told a cub reporter, 'Socially, a journalist fits in somewhere between a whore and a bartender. But spiritually he stands beside Galileo. He knows the world is round.' Well, socia...
Scientists still do not appear to understand sufficiently that all earth sciences must contribute evidence toward unveiling the state of our planet in earlier times, and that the truth of the matter can only be reached by combing all this evidence. ....
Frederick Douglass told in his Narrative how his condition as a slave became worse when his master underwent a religious conversion that allowed him to justify slavery as the punishment of the children of Ham. Mark Twain described his mother as a gen...
Before an experiment can be performed, it must be planned—the question to nature must be formulated before being posed. Before the result of a measurement can be used, it must be interpreted—nature's answer must be understood properly. These two ...
I think that the event which, more than anything else, led me to the search for ways of making more powerful radio telescopes, was the recognition, in 1952, that the intense source in the constellation of Cygnus was a distant galaxy—1000 million li...
