When the Special Theory of Relativity began to germinate in me, I was visited by all sorts of nervous conflicts... I used… — Albert Einstein Copy Share Image
We can invent as many theories we like, and any one of them can be made to fit the facts. But that… — Albert Einstein Copy Share Image
No matter how we may single out a complex from nature...its theoretical treatment will never prove to be ultimately conclusive... I believe… — Albert Einstein Copy Share Image
It must be conceded that a theory has an important advantage if its basic concepts and fundamental hypotheses are 'close to experience,'… — Albert Einstein Copy Share Image
The relativity principle in connection with the basic Maxwellian equations demands that the mass should be a direct measure of the energy… — Albert Einstein Copy Share Image
[Max Planck] was one of the finest people I have ever known... but he really didn't understand physics, [because] during the eclipse… — Albert Einstein Copy Share Image
It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing -… — Albert Einstein Copy Share Image

As soon as science has emerged from its initial stages, theoretical advances are no longer achieved merely by a process of arrangement.… — Albert Einstein Copy Share Image
A theory is the more impressive the greater the simplicity of its premises is, the more different kinds of things it relates,… — Albert Einstein Copy Share Image
Creating a new theory is not like destroying an old barn and erecting a skyscraper in its place. It is rather like… — Albert Einstein Copy Share Image
“Then there occurred to me the 'glucklichste Gedanke meines Lebens,' the happiest thought of my life, in the following form. The gravitational… — Albert Einstein Copy Share Image
One scientific epoch ended and another began with James Clerk Maxwell. — Albert Einstein Copy Share Image
In theory, theory and practice are the same. In practice, they are not. — Albert Einstein Copy Share Image
Mysticism is in fact the only criticism people cannot level against my theory. — Albert Einstein Copy Share Image

Common sense is nothing more than a deposit of prejudices laid down in the mind before you reach eighteen. — Albert Einstein Copy Share
The most fundamental question we can ever ask ourselves is whether or not the universe we live in is friendly or hostile. — Albert Einstein Copy Share
A knowledge of the existence of something we cannot penetrate, of the manifestations of the profoundest reason and the most radiant beauty - it… — Albert Einstein Copy Share
You imagine that I look back on my life's work with calm satisfaction. But from nearby it looks quite different. There is not a… — Albert Einstein Copy Share
The right to search for the truth implies also a duty; one must not conceal any part of what one has recognized to be… — Albert Einstein Copy Share
Everything that is really great and inspiring is created by the individual who can labor in freedom. — Albert Einstein Copy Share
