Quotes About Reality

Or does it mean, as it seems to me, that we must accept the idea that reality is only interaction?

Dolay?s?yla olas?l?k, cisimlerin de?i?imiyle ilgili de?ildir. Ba?ka cisimlerle etkile?tiklerinde, cisimlerin özellik alt s?n?flar?n?n de?erlerinin de?i?imiyle ilgilidir.

The present is like the flatness of Earth: an illusion. We

For Plato, forms exist by themselves, in an ethereal ideal world of forms, a world of "ideas." The idea of a horse exists prior to and independently of any actual horse. For Plato, a real horse is nothing but a pale reflection of the idea of a horse. The atoms that make up the horse count for little: what counts is the "horseness," the abstract form.

This is the flow of time familiar from our experience. It is inside there that it nestles. Inside of us. The utterly crucial presence of traces of the past in our neurons. Proust could not be more explicit on this matter. Writing in the first book, "Reality is formed only by memory" and memory in its turn is a collection of traces-an indirect product of the disordering of the world.

Our moral values, our emotions, our lives are no less real for being part of nature, for being shared with the animal world, or for being determined by the evolution which our species has undergone over millions of years. Rather, they are more valuable as a result of this: they are real

The difference between past and future, between cause and effect, between memory and hope, between regret and intention . . . in the elementary laws that describe the mechanisms of the world, there is no such difference.

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.

Remember that a key result of quantum mechanics is precisely the fact that information is finite. The number of alternative results that we can obtain measuring a physical system* is infinite in classical mechanics; but thanks to quantum theory, we have understood that, in reality, it is finite. Quantum mechanics can be understood as the discovery that information in nature is always finite.

What role do we have as human beings who perceive, make decisions, laugh, and cry, in this great fresco of the world as depicted by contemporary physics?

Carlo Rovelli

We are stories, contained within the twenty complicated centimeters behind our eyes, lines drawn by traces left by the (re)mingling together of things in the world, and oriented toward the direction of increasing entropy, in a rather particular corner of this inmense, chaotic universe.

A handful of elementary ingredients that act like bricks in a gigantic Lego set, and with which the entire material reality surrounding us is constructed. The nature of these particles, and the way they move, is described by quantum mechanics.

A novel image of the world is taking shape: a world without space and without time. The space where the world "inhabits" and the time "along which" things evolve might soon disappear from our fundamental description of the physical world, in the same manner in which notions such as "the centre of the universe" have disappeared in the past.

Our moral values, our emotions, our loves are no less real for being part of nature, for being shared with the animal world, or for being determined by the evolution which our species has undergone over millions of years. Rather, they are more valuable as a result of this: they are real. They are the complex reality of which we are made. Our reality is tears and laughter, gratitude and altruism, loyalty and betrayal, the past which haunts us and serenity.

Time is an effect of our overlooking the physical microstates of things. Time is information we don't have. Time is our ignorance.

Why do we remember the past and not the future?

If the present has no meaning, then what "exists" in the universe? Is not what "exists" precisely what is here "in the present"?

we are nothing but images of images. Reality, including our selves, is nothing but a thin and fragile veil, beyond which . . . there is nothing.

Hollandal? felsefeci Baruch Spinoza'n?n 17. yüzy?lda müthi? bir sa?duyuyla anlad??? gibi, bu ikisi ayn? ?eydir. "Ben" ve "beynimdeki nöronlar" diye iki ayr? ?ey yoktur. Bu ikisi ayn?d?r. Bir birey, karma??k ama s?k? s?k?ya bütünle?ik bir süreçtir.

The "quantum leaps" from one orbit to another constitute their way of being real: an electron is a combination of leaps from one interaction to another.

Despite certain obscurities,

Newton asserts explicitly in his book that we can't ever measure the true time t, but if we assume that it exists, we can set up an efficient framework to describe nature.

It must not be claimed that anyone can sense time by itself apart from the movement of things. LUCRETIUS, De rerum natura1
