“We know that the uncertainty relation implies not only the absence of empty space but also the nature of the minimal content… — Henning Genz Copy Share Image
“We don't really know whether there are black holes that emit observable amounts of Hawking radiation. Nevertheless, there is no way to… — Henning Genz Copy Share Image
“The laws of quantum mechanics don't permit the removal of arbitrary amounts of energy from a system consisting of two mutually attractive… — Henning Genz Copy Share Image
“If they were as we described them, the existence of black holes would contradict the principles of thermodynamics. One of these principles… — Henning Genz Copy Share Image
“We have good reason to believe that space and time begin to merge into quantum mechanical uncertainty at distances this small; they… — Henning Genz Copy Share Image
“The parameter we hold responsible for the ability or inability of a particle to move with a velocity other than that of… — Henning Genz Copy Share Image
“INTO AND OUT OF THE VACUUM To make real particles out of the virtual ones that are part of the vacuum fluctuations,… — Henning Genz Copy Share Image
“This question about the reason we do not observe any quantum mechanical uncertainty in the appearance of flies or stars was never… — Henning Genz Copy Share Image
“As we showed in figure 5, water molecules oscillate about their rest positions in ice. Quantum mechanics says that this remains true… — Henning Genz Copy Share Image
“Positional, or potential energy, is the energy we add to a rock when we lift it from the floor and put it… — Henning Genz Copy Share Image
“The field of the electron is real because it results from the laws of quantum mechanics and appropriate initial conditions. The laws… — Henning Genz Copy Share Image
“Recall our discussion of the pendulum. Its position at a given instant does not fix its subsequent behavior. Suppose a photograph shows the pendulum… — Henning Genz Copy Share Image
“Just as with sound waves, light waves emitted by a moving source show the Doppler effect. What we observe instead of the sound pitch… — Henning Genz Copy Share Image
“The interpretation of apparent long-distance action by means of continuously propagating effects was vigorously asserted by Isaac Newton. In his wake, the interpretation of… — Henning Genz Copy Share Image
“The quantity that physicists call the specific heat of a substance is defined as the amount of energy needed to raise the temperature of… — Henning Genz Copy Share Image
“To gain any intuitive understanding of the breakdown of this ultimate symmetry through vacuum effects at the critical 10^-44 seconds after the Big Bang,… — Henning Genz Copy Share Image
“To illustrate this relation, think of a game of table tennis. As the ball hits the table, it will bounce up and down. When… — Henning Genz Copy Share Image
“Before the particles that we observe today materialized, all matter in the early universe must have gone through this stage of a quark-gluon soup,… — Henning Genz Copy Share Image
“In physics terms, the reason for symmetry breaking is the instability of the symmetric state.” — Henning Genz Copy Share Image
“What really transcends our understanding is the mechanism that permits these oscillations of abstract field quantities to carry energy. We know this is true;… — Henning Genz Copy Share Image
“Chaotic or disordered distributions are symmetrical on the average. An observer cannot conclude anything about his location from looking around him. An example is… — Henning Genz Copy Share Image
“The hotter a substance, the faster and the less ordered its molecular motion, and the larger the momentum with which molecules collide. Above 0… — Henning Genz Copy Share Image
“This elementary process is symbolically illustrated in figure 59c: A photon becomes an electron-positron pair; inversely, an electron and a positron can combine into… — Henning Genz Copy Share Image
