Quotes About Physics

Since everything warmer than absolute zero radiates heat, detecting infrared at a distance means, in principle, detecting everything.

going through a wormhole or (as we shall see) by going around a cosmic string.

The former pair offered physics and logic; the latter offered primarily politics and fear plus a

But because the particle shower moves so fast relative to us and our detectors on Earth's surface, the muons experience the passage of time more slowly than we do.

Al principio, era la física. La

One thing quarks do have going for them: all their names are simple—something chemists, biologists, and especially geologists seem incapable of achieving when naming their own stuff.

after the laws of physics, everything else is opinion.

El físico teórico estadounidense del siglo XX John Archibald Wheeler lo expresó de mejor forma, resumiendo el concepto de Einstein como: "La materia le dice al espacio cómo curvarse; el espacio la dice a la materia cómo moverse".4

Ordered it with whipped cream, of course. When it arrived at the table, I saw no trace of the stuff. After I told the waiter that my cocoa had no whipped cream, he asserted I couldn't see it because it sank to the bottom. But whipped cream has low density, and floats on all liquids that humans consume. So I offered the waiter two possible explanations: either somebody forgot to add the whipped cream to my hot cocoa or the universal laws of physics were different in his restaurant.

matter and all the energy of the known universe was contained in a volume less than one-trillionth the size of the period that ends this sentence.

The largest black hole that could have evaporated since the big bang would have to have been smaller than an atomic nucleus.

la materia le dice al espacio cómo curvarse, y el espacio le dice a la materia cómo moverse.

Frozen water is less dense than liquid water…and ice floats. In the winter, the top surface [of a lake] gets cold. The top water will freeze, and not drop, thereby insulating the liquid water below, protecting the fishes through the winter months. It's a remarkable feature of water.

consider a spherical cow.

En otras palabras, después de las leyes de la física, lo demás es una opinión.

typical human adults constantly experience nearly 20 tons of force on their bodies, just from Earth's atmosphere!

A Congreve clock?' Captain Petersen was puzzled. 'It's a clock that keeps time by a steel ball running on a zig-zag track down an inclined plane,' Keith told him. 'Only it doesn't keep very good time. It takes thirty seconds for the ball to run down one way — then the plane tilts and it runs back again. It's quite fascinating to watch.

People think when you're moving in Zero-G, it's like moving in jelly. But it's not. You're completely free to move however fast as you want.

You can take the entire world of physics with all of its macrocosm and microcosm, its quantum mechanics and nuclear physics and reduce it to one word: energy. It's all energy. Scientists say that if you can't measure it, weight it, or see it, it doesn't exist. Well, no one has ever seen energy. We can see its effects, but not it.

Neutrinos come from the core of our Sun and from the core of every star in our galaxy close enough for its neutrinos to have reached us.

Either one attributes one's presence here to the laws of biology and physics, or one attributes it to a divine design.

Between them, the sciences of textual criticism, archaeology, physics, and molecular biology have shown religious myths to be false and man-made and have also succeeded in evolving better and more enlightened explanations.

In science, 'fact' can only mean 'confirmed to such a degree that it would be perverse to withhold provisional assent.' I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.*6

Lense–Thirring effect, aka: frame-dragging).
