Quotes About Science

The answer is that each element corresponds to one solution of the main equation of quantum mechanics. The whole of chemistry emerges from a single equation.

I think that quantum mechanics has revealed three aspects of the nature of things: granularity, indeterminacy, and the relational structure of the world.

Looking at the sun going down, the eye of Copernicus had seen the world turning. Looking at a glass of still water, the eyes of Boltzmann saw atoms and molecules frenziedly moving

This clarified, here is the point: it is possible to think of quantum physics as a theory of information (in the sense outlined) that systems have about one another.

Without clues, we search in the wrong directions. Without evidence, a theory is not reliable.

This is also true from a methodological point of view: a scientist orients his own research on the basis of epistemological ideas. He might be more or less aware of them. Very often to be aware of your own assumptions is far better than to be guided by methodological prejudices of which you are unaware.

I think that the obscurity of the theory is not the fault of quantum mechanics but is rather due to the limited capacity of our imagination. When we try to "see" the quantum world, we are rather like moles used to living underground, to whom someone is trying to describe the Himalayas. Or like the men imprisoned at the back of Plato's cave.

Any description of a system is therefore always a description of the information a system has about another system, that is to say, the correlation between the two systems. The

Only where there is heat is there a distinction between past and future.

This reads: "Delta S is always greater than or equal to zero," and we call this "the second principle of thermodynamics

La confusione fra queste due diverse attività umane, inventare racconti e seguire tracce per trovare qualcosa, è l'origine dell'incomprensione e della diffidenza per la scienza di una parte della cultura contemporanea.

In the big picture of contemporary science, there are many things that we do not understand, and one of the things that we understand least about is ourselves.

Planets circle around the sun, and things fall, because space around them is curved.

To the very last, the desire to debate, to understand more. To the very last, doubt. This permanent doubt, the deep source of science.

Our culture is foolish to keep science and poetry separated: they are two tools to open our eyes to the complexity and beauty of the world.

The Einstein who makes more errors than anyone else is precisely the same Einstein who succeeds in understanding more about nature than anyone else.

El pensamiento científico se nutre de la capacidad de ver las cosas de manera distinta de cómo las veíamos antes

Thus, it is possible to measure time by simply counting the oscillations of a pendulum. It seems such an obvious idea, but it took Galileo to find it; it had not occurred to anyone before him. So it goes, with science.

Perhaps poetry is another of science's deepest roots: the capacity to see beyond the visible.

Whenever you consider a phenomenon certifying the passage of time , it is through the production of heat that it does so. There is no preferred direction of time without heat.

The apparent determinism of the macroscopic world is due only to the fact that the microscopic randomness cancels out on average, leaving only fluctuations too minute for us to perceive in everyday life.

This means not giving credence to those who say they are in possession of the truth. For this reason, science and religion frequently find themselves on a collision course. Not because science pretends to know ultimate answers, but precisely for the opposite reason: because the scientific spirit distrusts whoever claims to be the one having ultimate answers or privileged access to Truth.

Einstein's equation shows that space cannot stand still; it must be expanding. In 1930 the expansion of the universe was actually observed.

If Planck is the father of the theory, Einstein is the parent who nurtured it.
