Quotes About Physics

At our meeting, I suggested to Steven and Lynda two guidelines for the science of Interstellar: 1. Nothing in the film will violate firmly established laws of physics, or our firmly established knowledge of the universe. 2. Speculations (often wild) about ill-understood physical laws and the universe will spring from real science, from ideas that at least some "respectable" scientists regard as possible.

No matter how hard we may try, we can only travel forward. The relativistic laws guarantee it.

tres números, su masa, su momento angular y su carga eléctrica. El

We humans are confined to our brane.

La violación es solamente una peculiaridad minúscula en las leyes de la física, una que presumiblemente soportan las leyes con gusto.

If we begin with the ill-understood laws of quantum gravity and then discard the fluctuations, we must obtain Einstein's well-understood relativistic laws of physics. The fluctuations we discard are, for example, a froth of fluctuating, exquisitely tiny wormholes ("quantum foam" that pervades all of space; Figure 26.3 and Chapter 14).

so matter as we know it gets stretched and squeezed out of existence.

política cuántica», que describe cómo el mundo clásico de la física postnewtoniana (lineal, predecible y, hasta cierto punto, incluso determinista) había dado paso al mundo cuántico: altamente interconectado e incierto, increíblemente complejo y también cambiante en función de la posición del observador.

The models of modern physics are concerned, therefore, both with con- tinuous and discrete values. It would seem appropriate to consider a hybrid system. It will be extremely difficult to find a technical model of a hybrid computer which behaves according to the laws of quantum physics.

The author has greatly enjoyed being able to discuss this subject with a few mathematicians and physicists. The greatest handicap to cooperation is certainly the difference in terms between the individual, specialized fields of knowledge. We hope that this chasm will be bridged in time and that through cybernetics, a true bridge between physics and the automaton theory can be built.

The First Law simply states that the change in total energy equals the work performed on, plus the heat supplied to, the system (measured in suitable units).

Now up to the end of the eighteenth century, notably in the work of chemists, heat was treated as a substance, named caloric by the great French chemist Antoine Laurent Lavoisier (1743–1794), who made the first attempt to introduce the methods and concepts of physics laid down by Galileo and Newton into chemistry.

heat "always shows a tendency to equalize temperature differences and therefore to pass from hotter to colder bodies" [15]. A

It is entropy, not energy, that keeps stones on the ground and the world turning.

Temporality is profoundly linked to blurring. The blurring is due to the fact that we are ignorant of the microscopic details of the world. The time of physics is, ultimately, the expression of our ignorance of the world. Time is ignorance.

If things fall, it is due to this slowing down of time. Where time passes uniformly, in interplanetary space, things do not fall. They float, without falling. Here on the surface of our planet, on the other hand, the movement of things inclines naturally toward where time passes more slowly, as when we run down the beach into the sea and the resistance of the water on our legs makes us fall headfirst into the waves. Things fall downward because, down there, time is slowed by the Earth.

A university student attending lectures on general relativity i the morning and others on quantum mechanics in the afternoon might be forgiven for thinking that his professors are fools, or have neglected to communicate with each other for at least a century.

The heat of black holes is like the Rosetta stone of physics, written in a combination of three languages- quantum, gravitational, and thermodynamic- still awaiting decipherment in order to reveal the true nature of time.

Those who defend this way of thinking about reality—eternalism—frequently cite Einstein, who in a famous letter writes: For people like us who believe in physics the distinction between past, present and future is only a stubbornly persistent illusion.

Space is created by the interaction of individual quanta of gravity.

if nothing else around it changes, heat cannot pass from a cold body to a hot one......This is the only basic law of physics that distinguishes the past from the future.

Electrons, quarks, photons, and gluons are the components of everything that sways in the space around us. They are the "elementary particles" studied in particle physics.

People like us, who believe in physics, know that the distinction made between past, present and future is nothing more than a persistent, stubborn illusion." Illusion

Time, as Aristotle suggested, is the measure of change;
