Famous Physics Quotes & Sayings

As a boy I had liked both drawing and physics, and I always abhorred the role of being a spectator. In 1908, when I was 15, I designed, built and flew a toy model airplane which won the then-famous James Gordon Bennett Cup. By 16 I had discovered that design could be fun and profitable, and this lesson has never been lost on me. — Raymond Loewy

Albert Einstein, who discovered that a tiny amount of mass is equal to a huge amount of energy, which explains why, as Einstein himself so eloquently put it in a famous 1939 speech to the Physics Department at Princeton, 'You have to exercise for a week to work off the thigh fat from a single Snickers.' — Dave Barry

God plays dice with the universe," is Ford's answer to Einstein's famous question. "But they're loaded dice. And the main objective of physics now is to find out by what rules were they loaded and how can we use them for our own ends. — James Gleick

As Sommerfeld said in his famous text "Spectral Lines and Atomic Constitution," on which a generation of physicists learned the subject, "In the fine structure constant e is the representative of the electron theory, h the appropriate representative of the quantum theory, c comes from relativity and characterizes it in contrast to classical theory. — Emilio Segre

The strength of the familiar electromagnetic force between two electrons, for example, is expressed in physics in terms of a constant known as the fine structure constant. The value of this constant, almost exactly 1/137, has puzzled many generations of physicists. A joke made about the famous English physicist Paul Dirac (1902-1984), one of the founders of quantum mechanics, says that upon arrival to heaven he was allowed to ask God one question. His question was: "Why 1/137? — Mario Livio

As the twentieth century began, science equaled a materialistic worldview. As the twenty-first century began, the worldview of science, at least of physics and astronomy, may have traded place with that of religion. Consider Einstein's famous equation E = mc2. Nothing of matter dies but continues on in another form, elsewhere. The church divines and theologians for two thousand years have devised arguments and "proofs" of immortality but nothing equal to this. — Huston Smith

Lederman is also a charismatic personality, famous among his colleagues for his humor and storytelling ability. One of his favorite anecdotes relates the time when, as a graduate student, he arranged to bump into Albert Einstein while walking the grounds at the Institute for Advanced Study at Princeton. The great man listened patiently as the eager youngster explained the particle-physics research he was doing at Columbia, and then said with a smile, That is not interesting. — Sean Carroll

Eugene Wigner wrote a famous essay on the unreasonable effectiveness of mathematics in natural sciences. He meant physics, of course. There is only one thing which is more unreasonable than the unreasonable effectiveness of mathematics in physics, and this is the unreasonable ineffectiveness of mathematics in biology. — Israel Gelfand

But some numbers, called dimensionless numbers, have the same numerical value no matter what units of measurement are chosen. Probably the most famous of these is the "fine-structure constant," ... Physicists love this number not just because it is dimensionless, but also because it is a combination of three fundamental constants of nature. — John Archibald Wheeler

One of the various theories proposed to explain the negative result of the famous Michelson-Morley experiment with light waves (conceived to measure the absolute space), was based on the ballistic hypothesis, i.e. on postulating that the speed of light predicted by Maxwell's equations was not given as relative to the medium but as relative to the transmitter (firearm). Had that been the case, the experiment negative results would have not caused such perplexity and frustration (as we shall see in forthcoming sections). — Felix Alba-Juez

The strength of the electromagnetic interaction, for example, is fixed by a number called the "fine-structure constant," a famous quantity in physics that is numerically close to 1/137. — Sean Carroll
