Quotes About Uncertainty

Hold on tight, because we are about to take off. "NOW" MEANS NOTHING What is happening "now" in a distant place? Imagine, for example, that your sister has gone to Proxima b, the recently discovered planet that orbits a star at approximately four light-years' distance from us. What is your sister doing now on Proxima b? The only correct answer is that the question makes no sense. It is like asking "What is here, in Beijing?" when we are in Venice.

To accept uncertainty doesn't detract from our sense of mystery.

Genuis hesitates

Lo que nos hace avanzar es la duda y no la certeza.

Quantum uncertainty across the horizon of the black hole generates fluctuations of the horizon geometry. But "fluctuations" imply "probability," and probability implies thermodynamics, and therefore temperature. Concealing from us a part of the universe, a black hole makes its quantum fluctuations detectable in the form of heat.

Infinite', ultimately, is the name that we give to what we do not yet know. Nature appears to be telling us that there is nothing truly infinite.

Therefore the scientific quest for knowledge is not nourished by certainty, it is nourished by a radical lack of certainty. Its way is fluid, capable of continuous evolution, has immense strength and a subtle magic. It is able to overthrow the order of things and reconceive the world time and again.

Kuantum mekani?inde, bir ba?ka cisimle çarp??mad??? sürece hiçbir cismin belirli bir konumu yoktur.

Çok h?zl? hareket eden dalgac?klard?r. Kuantum mekani?inin garip kurallar?na göre yok olup yeniden ortaya ç?karlar, var olan ?eyler hiçbir zaman kararl? bir durumda olmaz; bir etkile?imden di?erine gerçekle?en bir s?çramadan ba?ka bir ?ey de?ildirler.

Se il mondo è un un pullulare di effimeri quanti di spazio e di materia, un immenso gioco a incastri di spazio e particelle elementari, noi cosa siamo? [...] Nel grande quadro della scienza contemporanea ci sono molte cose che non capiamo, e una di quelle che capiamo meno siamo noi stessi

I may not know something with certainty, but I can still assign a lesser or greater degree of probability to something.

It is the limit up to which we can determine physical variables.

information is the measure of the number of possible alternatives for something.

When we seek a sure foundation on which to base decisions about our actions and thoughts, we find that a sure foundation does not exist. We do not even know whether we actually need such a foundation. We continue to make use of vague, uncertain ideas, precisely in those areas that most deeply concern us. What we call "irrational" is the code name for what we don't understand well about ourselves given the limits of our own intelligence.

Democritus himself, who had placed empty space at the basis of his world where atoms course, certainly wasn't crystal clear on the issue: he wrote that empty space is something "between being and non-being":

information is the measure of the number of possible alternatives for something. For example, if I throw a die, it can land on one of six faces.

entropy, as Boltzmann fully understood, is nothing other than the number of microscopic states that our blurred vision of the world fails to distinguish.

Despite certain obscurities,

The theory also gives information on which value of the spectrum will manifest itself in the next interaction, but only in the form of probabilities. We do not know with certainty where the electron will appear, but we can compute the probability that it will appear here or there.

We usually speak of probability when we do not have all the data.

The world of quantum mechanics is not a world of objects: it is a world of events.

Science is the human adventure of accepting uncertainty, exploring ways of thinking about the world, and being ready to overturn any and all certainties we have possessed to this point. This is among the most beautiful of human adventures.

was a planless life, hopeless, and without direction. I was merely living from day to day: yesterday seemed long ago and tomorrow was too far away.

Carlos, sossegue, o amor é isso que você está vendo: hoje beija, amanhã não beija, depois de amanhã é domingo e segunda-feira ninguém sabe o que será.
