A desk, some pads, a pencil, and a large basket - to hold all of my mistakes.
-
The special theory of relativity owes its origins to Maxwell's equations of the electromagnetic field.
-
The Jewish scriptures admirably illustrate the development from the religion of fear to moral religion, a development continued in the New Testament. The religions of all civilized peoples, especially the peoples of the Orient, are primarily moral religions.
-
The desire for guidance, love, and support prompts men to form the social or moral conception of God. This is the God of Providence, who protects, disposes, rewards, and punishes; the God who, according to the limits of the believer's outlook, loves and cherishes the life of the tribe or of the human race, or even of life itself; the comforter in sorrow and unsatisfied longing; he who preserves the souls of the dead. This is the social or moral conception of God.

It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing - a somewhat unfamiliar conception for the average mind. Furthermore, the equation E = mc², in which energy is put equal to mass, multiplied by the square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa.
-
Each ray of light moves in the coordinate system 'at rest' with the definite, constant velocity V independent of whether this ray of light is emitted by a body at rest or a body in motion.
-
Scientific research is based on the idea that everything that takes place is determined by laws of Nature, and therefore this holds for the action of people. For this reason, a research scientist will hardly be inclined to believe that events could be influenced by a prayer, i.e. by a wish addressed to a Supernatural Being.
-
That's my mathematician who examines problems which I put before him and checks their validity. You see, I am not myself a good mathematician.
-
On the other hand, the concept owes its meaning and its justification exclusively to the totality of the sense impressions which we associate with it.
-
The chicken did not cross the road. The road passed beneath the chicken.
-
I could say analogously that tolerance is the affable appreciation of qualities, views, and actions of other individuals which are foreign to one`s own habits, beliefs, and tastes. Thus being tolerant does not mean being indifferent towards the actions and feelings of others. Understanding and empathy must also be present.
-
I have become an obstinate heretic in the eyes of my colleagues. Momentary success carries more power of conviction than reflections upon principles.
-
Unless Americans come to realize that they are not stronger in the world because they have the bomb but weaker because of their vulnerability to atomic attack, they are not likely to conduct their policy at Lake Success the United Nations or in their relations with Russia in a spirit that furthers the arrival at an understanding.
-
I do not believe in free will. Schopenhauer's words: 'Man can do what he wants, but he cannot will what he wills,' accompany me in all situations throughout my life and reconcile me with the actions of others, even if they are rather painful to me. This awareness of the lack of free will keeps me from taking myself and my fellow men too seriously as acting and deciding individuals, and from losing my temper.
-
The field is the sole influence of the particle.
-
The opinion prevailed among advanced minds that it was time that belief should be replaced increasingly by knowledge; belief that did not itself rest on knowledge was superstition, and as such had to be opposed.
-
I cannot conceive of a personal God who would directly influence the actions of individuals, or would directly sit in judgment on creatures of his own creation.
-
Matter is spirit reduced to point of visibility.
-
There is a duty in refusing to cooperate in any undertaking that violates the Constitutional rights of the individual. This holds in particular for all inquisitions that are concerned with the private life and the political affiliations of the citizens.
-
Watch the stars, and from them learn.
-
Physics is an attempt conceptually to grasp reality as something that is considered to be independent of its being observed. In this sense one speaks of physical reality.
-
Epistemology without contact with science becomes an empty scheme. Science without epistemology is-insofar as it is thinkable at all-primitive and muddled.
-
Play is the highest from of research.
-
But the creative principle resides in mathematics. In a certain sense, therefore, I hold true that pure thought can grasp reality, as the ancients dreamed.
