“The parameter we hold responsible for the ability or inability of a particle to move with a velocity other than that of light is its mass. When the mass is zero, such as that of a real photon, the particle… — 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
“John Maddox, the editor of the British journal Nature, had immediately suggested that the minister should be told that the Higgs boson can be… — Henning Genz Copy Share Image
“At first glance, it may appear odd that the black hole loses mass upon absorbing another mass-that of the electron. Actually, this seeming paradox… — Henning Genz Copy Share Image
“We can now infer that at this initial cooldown of the universe across the critical temperature of 10^15 degrees, a mini planetary system might… — Henning Genz Copy Share Image
