Quotes About Time

In his youth Albert Einstein spent a year loafing aimlessly. You don't get anywhere by not 'wasting' time – something, unfortunately, which the parents of teenagers tend frequently to forget. He

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'.

the particles are quanta of quantum fields; light is formed by quanta of a field; space is nothing more than a field, which is also made of quanta; and time emerges from the processes of this same field. In other words, the world is made entirely from quantum fields (

T]he elementary form of the mechanics of the world...does not need to mention 'time.' The world without a time variable is not a complicated one. It's a net of interconnected events, where the variables in play adhere to probabilistic rules that, incredibly, we know for a good part how to write. And it's a clear world, windswept and full of beauty as the crests of mountains; aridly beautiful as the cracked lips of the adolescent you loved.

There is not one single time; there is a vast multitude of them.

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.*

Time has lost its first aspect or layer: its unity. It has a different rhythm in every different place and passes here differently from there.

Anche le parole che ora diciamo il tempo nella sua rapina ha già portato via e nulla torna (I, 11)

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

Even the words that we are speaking now thieving time has stolen away, and nothing can return. (I, 11)

Albert Einstein, yak?n dostu ?talyan Michele Besso öldü?ünde onun k?z karde?ine dokunakl? bir mektu yazm??t?: "Michele bu garip dünyadan benden biraz önce ayr?ld?. Bunun hiçbir anlam? yok. Bizim gibi fizi?e inanan insanlar, geçmi?, ?imdi ve gelecek aras?ndaki ayr?m?n sürüp giden inatç? bir yan?lsamadan ba?ka bir ?ey olmad???n? bilir.

The crucial point here is the difference from what happens with falling bodies: a ball may fall, but it can also come back up, by rebounding, for instance. Heat cannot. This is the only basic law of physics that distinguishes the past from the future.

The nature of time is perhaps the greatest remaining mystery. Curious threads connect it to those other great open mysteries: the nature of mind, the origin of the universe, the fate of black holes, the very functioning of life on Earth. Something essential continues to draw us back to the nature of time.

Why do we remember the past and not the future? Do we exist in time, or does time exist in us? What does it really mean to say that time "passes"? What ties time to our nature as persons, to our subjectivity? What am I listening to when I listen to the passing of time?

It is the presence of abundant traces of the past that produces the familiar sensation that the past is determined.

Uzay - zaman?n kuantum dalgalanmalar?n?n yaratt??? bas?nc?n maddenin a??rl???n? dengeledi?i bir y?ld?z?n ya?am?n?n bu varsay?msal sona erme durumuna "Planck y?ld?z?" ad? verilir.

What happens between one interaction and the next is not mentioned in the theory. It does not exist.

In the elementary equations of the world,13 the arrow of time appears only where there is heat.* The link between time and heat is therefore fundamental: every time a difference is manifested between the past and the future, heat is involved. In every sequence of events that becomes absurd if projected backward, there is something that is heating up.

Dances of love intertwine such graceful girls lit by the moon on these clear nights. (I, 4) THE SLOWING DOWN OF TIME

The proposal is not well received, because people are attached to local time. In 1883, a compromise is reached with the idea of dividing the world into time zones, thereby standardizing time only within each zone. In this way, the discrepancy between twelve on the clock and local midday is limited to a maximum of about thirty minutes. The proposal is gradually accepted by the rest of the world and clocks begin to be synchronized between different cities.

The difference between past and future does not lie in the elementary laws of motion; it does not reside in the deep grammar of nature. It is the natural disordering that leads to gradually less particular, less special situations.
