Quotes About Physics

At the most fundamental level that we currently know of, therefore, there is little that resembles time as we experience it.

But it is not only space that curves: time does too. Einstein predicts that time on Earth passes more quickly at higher altitude, and more slowly at lower altitude.

Kütle çekim alan? uzayda yay?lm?? de?ildi, çekim alan? uzay?n ta kendisiydi.

The difference between past and future exists only when there is heat. The fundamental phenomenon that distinguishes the future from the past is the fact that heat passes from things that are hotter to things that are colder.

Uzay maddenin var olduÄŸu yerde eÄŸrilir.

Ama bükülen yaln?zca uzay de?ildir; zaman da bükülür. Einstein zaman?n yüksekteki bir konumda, dünyaya yak?n, daha alçak bir durumdan daha h?zl? akt???n? öngörür.

Color is the speed at which Faraday's lines vibrate, and this is determined by the vibrations of the electric charges that emit light.

A dolgok csak egymáshoz képest változnak. A világ alapszerkezetében nincs id?. Az id? múlásának érzete csupán közelítés, és csak a mi makroszkopikus mérettartományunkban érvényes.

The difference between past and future exists only when there is heat. The fundamental phenomenon that distinguishes the future from the past is the fact that heat passes from things that are hotter to things that are colder. So,

Carlo Rovelli

Max Planck s?cak bir kutu içinde denge durumunda bulunan elektrik alan?n? hesaplar. Bunun için küçük bir hileye ba?vurur: Alan?n enerjisinin "kuantumlar" yani enerji paketçikleri, topaklar? biçiminde da??ld???n? varsayar.

If we try to put together what we have learned in the twentieth century about the physical world, the clues point toward something profoundly different from our instinctive understanding of matter, space, and time.

Black hole heat is directly connected to loop quantum gravity's fluctuations of the atoms of space.

Einstein ?????n paketlerden, ???k parçac?klar?ndan olu?tu?unu gösterdi. Bunlara bugün "fotonlar" diyoruz.

But in physics there is nothing that corresponds to the notion of the "now.

Times are legion: a different one for every point in space. There is not one single time; there is a vast multitude of them. The time indicated by a particular clock measuring a particular phenomenon is called 'proper time' in physics. Every clock has its proper time. Every phenomenon that occurs has its proper time, its own rhythm.

The probability of finding an electron or any other particle at one point or another can be imagined as a diffuse cloud, denser where the probability of seeing the particle is stronger. Sometimes it is useful to visualize this cloud as if it were a real thing. For instance, the cloud that represents an electron around its nucleus indicates where it is more likely that the electron appears if we look at it. If you have encountered them at school, these are the atomic orbitals.

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

What is the 'present'? We say that only the things of the present exist: the past no longer exists and the future doesn't exist yet. But in physics there is nothing that corresponds to the notion of the 'now'.

In tutti i casi in cui non viene scambiato calore, infatti, oppure quando il calore scambiato è trascurabile, noi vediamo che il futuro si comporta esattamente come il passato.

The time indicated by a particular clock measuring a particular phenomenon is called "proper time" in physics.

This is how time is depicted in Einstein's general theory of relativity. His equations do not have a single "time"; they have innumerable times.

Physics does not describe how things evolve "in time" but how things evolve in their own times, and how "times" evolve relative to each other.*

We often say that causes precede effects and yet, in the elementary grammar of things, there is no distinction between "cause" and "effect.
