Quotes & Sayings About The Atomic Theory

We may regard the cell quite apart from its familiar morphological aspects, and contemplate its constitution from the purely chemical standpoint. We are obliged to adopt the view, that the protoplasm is equipped with certain atomic groups, whose function especially consists in fixing to themselves food-stuffs, of importance to the cell-life. Adopting the nomenclature of organic chemistry, these groups may be designated side-chains. We may assume that the protoplasm consists of a special executive centre (Leistungs-centrum) in connection with which are nutritive side-chains... The relationship of the corresponding groups, i.e., those of the food-stuff, and those of the cell, must be specific. They must be adapted to one another, as, e.g., male and female screw (Pasteur), or as lock and key (E. Fischer). — Paul R. Ehrlich

Epicurus ... supposes not only all mixt bodies, but all others to be produced by the various and casual occursions of atoms, moving themselves to and fro by an internal principle in the immense or rather infinite vacuum. — Robert Boyle

The central idea of string theory is quite straightforward. If you examine any piece of matter ever more finely, at first you'll find molecules, atoms, sub-atomic particles. Probe the smaller particles, you'll find something else, a tiny vibrating filament of energy, a little tiny vibrating string. — Brian Greene

Quantum theory thus reveals a basic oneness of the universe. It shows that we cannot decompose the world into independently existing smallest units. As we penetrate into matter, nature does not show us any isolated "building blocks," but rather appears as a complicated web of relations between the various parts of the whole. These relations always include the observer in an essential way. The human observer constitute the final link in the chain of observational processes, and the properties of any atomic object can be understood only in terms of the object's interaction with the observer. — Fritjof Capra

The popular conception of any philosophical doctrine is necessarily imperfect, and very generally unjust. Lucretius is often alluded to as an atheistical writer, who held the silly opinion that the universe was the result of a fortuitous concourse of atoms readers are asked to consider how long letters must be shaken in a bag before a complete annotated edition of Shakespeare could result from the process; and after being reminded how much more complex the universe is than the works of Shakespeare, they are expected to hold Lucretius, with his teachers and his followers, in derision. A nickname which sticks has generally some truth in it, and so has the above view, but it would be unjust to form our judgment of a man from his nickname alone, and we may profitably consider what the real tenets of Lucretius were, especially now that men of science are beginning, after a long pause in the inquiry, once more eagerly to attempt some explanation of the ultimate constitution of matter. — Fleeming Jenkin

The present state of atomic theory is characterized by the fact that we not only believe the existence of atoms to be proved beyond a doubt, but also we even believe that we have an intimate knowledge of the constituents of the individual atoms. — Niels Bohr

The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation. — Paul Dirac

[Chemist Michael] Polanyi found one other necessary requirement for full initiation into science: Belief. If science has become the orthodoxy of the West, individuals are nevertheless still free to take it or leave it, in whole or in part; believers in astrology, Marxism and virgin birth abound. But no one can become a scientist unless he presumes that the scientific doctrine and method are fundamentally sound and that their ultimate premises can be unquestionably accepted. — Richard Rhodes

From the point of view of logic, my report on 'Exclusion principle and quantum mechanics' has no conclusion. I believe that it will only be possible to write the conclusion if a theory will be established which will determine the value of the fine structure constant and will thus explain the atomistic structure of electricity, which is such an essential quality of all atomic sources of electric fields actually occurring in nature. — Wolfgang Pauli

When we blew the first atomic bomb at White Sands near the end of the war, nobody knew what was going to happen. There was a theory that the chain reaction would continue forever. And we would have created a little tiny sun out there in the desert that would burn until the end of the universe. It wasn't a widely held theory, but it was a theory that nobody had a way of disproving. There were people who thought it wouldn't go off at all, that it would simply sit out there and melt and produce a great big dirty cloud of radioactivity. Nobody knew. — Stephen King

Sommerfeld's fine-structure theory was generally considered to be excellently and unambiguously confirmed by experiment. Because the theory rested on the foundation provided by Bohr, the experiments were also taken as strong support for his theory of atomic structure. — Helge Kragh

Father Roger Boscovich is often credited as the father of modern atomic theory. — Thomas E. Woods Jr.

Fine Structure Constant: Fundamental numerical constant of atomic physics and quantum electrodynamics, defined as the square of the charge of the electron divided by the product of Planck's constant and the speed of light. — Steven Weinberg

In the vestibule of the Manchester Town Hall are placed two life-sized marble statues facing each other. One of these is that of John Dalton ... the other that of James Prescott Joule ... Thus the honour is done to Manchester's two greatest sons - to Dalton, the founder of modern Chemistry and of the atomic theory, and the laws of chemical-combining proportions; to Joule, the founder of modern physics and the discoverer of the Law of Conservation of Energy.
One gave to the world the final proof ... that in every kind of chemical change no loss of matter occurs; the other proved that in all the varied modes of physical change, no loss of energy takes place. — Henry Enfield Roscoe

86. [Our aim is] neither to achieve the impossible, even by force, nor to maintain a theory which is in all respects similar either to our discussions on the ways of life or to our clarifications of other questions in physics, such as the thesis that the totality [of things] consists of bodies and intangible nature, and that the elements are atomic, and all such things as are consistent with the phenomena in only one way. This — Epicurus

Both loop quantum gravity and string theory assert that there is an atomic structure to space. In the next two chapters we shall see that loop quantum gravity in fact gives a rather detailed picture of that atomic structure. The picture of the atomic structure one gets from string theory is presently incomplete but, as we shall see in Chapter 11, it is still impossible in string theory to avoid the conclusion that there must be an atomic structure to space and time. In Chapter 13 we shall discover that both pictures of the atomic structure of space can be used to explain the entropy and temperature of black holes. — Lee Smolin

[John] Dalton was a man of regular habits. For fifty-seven years he walked out of Manchester every day; he measured the rainfall, the temperature - a singularly monotonous enterprise in this climate. Of all that mass of data, nothing whatever came. But of the one searching, almost childlike question about the weights that enter the construction of these simple molecules - out of that came modern atomic theory. That is the essence of science: ask an impertinent question, and you are on the way to the pertinent answer. — Jacob Bronowski

Even when they are saturated in the sense of the older theory of valence, the elementary atoms still possess sufficient chemical affinity to bind other seemingly also saturated atoms and groups of atoms, under generation of clearly defined atomic bonds. — Alfred Werner

All integral laws of spectral lines and of atomic theory spring originally from the quantum theory. It is the mysterious organon on which Nature plays her music of the spectra, and according to the rhythm of which she regulates the structure of the atoms and nuclei. — Arnold Sommerfeld

(The string is extremely tiny, at the Planck length of 10 ^-33 cm, a billion billion times smaller than a proton, so all subatomic particles appear pointlike.)

If we were to pluck this string, the vibration would change; the electron might turn into a neutrino. Pluck it again and it might turn into a quark. In fact, if you plucked it hard enough, it could turn into any of the known subatomic particles.

Strings can interact by splitting and rejoining, thus creating the interactions we see among electrons and protons in atoms. In this way, through string theory, we can reproduce all the laws of atomic and nuclear physics. The "melodies" that can be written on strings correspond to the laws of chemistry. The universe can now be viewed as a vast symphony of strings. — Michio Kaku

Of thousands of others, nearer the centre of the explosion, there was no trace. They vanished. The theory in Hiroshima is that the atomic heat was so great that they burned instantly to ashes - except that there were no ashes. — Wilfred Burchett

I am an atheist, but as far as blowing up the world in a nuclear war goes, I tell them not to worry. — Fred Hoyle

Follow the loglo outward, to where the growth is enfolded into the valleys and the canyons, and you find the land of the refugees. They have fled from the true America, the America of atomic bombs, scalpings, hip-hop, chaos theory, cement overshoes, snake handlers, spree killers, space walks, buffalo jumps, drive-bys, cruise missiles; Sherman's March, gridlock, motorcycle gangs, and bungee jumping. They have parallel-parked their bimbo boxes in identical computer-designed Burbclave street patterns and secreted themselves in symmetrical sheetrock shitholes with vinyl floors and ill-fitting woodwork and no sidewalks, vast house farms out in the loglo wilderness, a culture medium for a medium culture. — Neal Stephenson

They have fled from the true America, the America of atomic bombs, scalpings, hip-hop, chaos theory, cement overshoes, snake handlers, spree killers, space walks, buffalo jumps, drive-bys, cruise missiles; Sherman's March, gridlock, motorcycle gangs, and bungee jumping. — Neal Stephenson

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

I am now convinced that we have recently become possessed of experimental evidence of the discrete or grained nature of matter, which the atomic hypothesis sought in vain for hundreds and thousands of years. The isolation and counting of gaseous ions, on the one hand, which have crowned with success the long and brilliant researches of J.J. Thomson, and, on the other, agreement of the Brownian movement with the requirements of the kinetic hypothesis, established by many investigators and most conclusively by J. Perrin, justify the most cautious scientist in now speaking of the experimental proof of the atomic nature of matter, The atomic hypothesis is thus raised to the position of a scientifically well-founded theory, and can claim a place in a text-book intended for use as an introduction to the present state of our knowledge of General Chemistry. — Wilhelm, Ostwald

It is shown that the golden ratio plays a prominent role in the dimensions of all objects which exhibit five-fold symmetry. It is also showed that among the irrational numbers, the golden ratio is the most irrational and, as a result, has unique applications in number theory, search algorithms, the minimization of functions, network theory, the atomic structure of certain materials and the growth of biological organisms. — Richard A. Dunlap

In early 1945 Berg did go to Switzerland, as depicted here a bit earlier, to kill Heisenberg if necessary. Sitting in the front row of Heisenberg's seminar, he determined that the Germans were nowhere near their goal, so he complimented Heisenberg on his speech about field theory and walked him back to his hotel. Moe Berg's report was distributed to Britain's prime minister, Winston Churchill, President Franklin D. Roosevelt, and key figures in the team developing the atomic bomb. Roosevelt responded: "Give my regards to the catcher." Werner — Gregory Benford

In the last four days I have got the (results) given by Tantalum, Chromium, Manganese, Iron , Nickel, Cobalt and Copper ... The chief result is that ... the result for any metal (is) quite easy to guess from the results for the others. This shews that the insides of all the atoms are very much alike, and from these results it will be possible to find out something of what the insides are made up of. — Henry Moseley

I get paid to do what I love. If you understand physics, the foundation of the atomic theory and relativity, you understand how the future is going to unfold. You understand what things are not possible. You understand why things work. I get paid to do what I love the most, and that is to work on the Unified Field Theory and to see the future. — Michio Kaku

There are many levels of consciousness, but atomic consciousness or universal consciousness is the basis of all other levels of consciousness. A tree is very much conscious even though in our point of view they are not conscious. — Debasish Mridha

Berzelius' symbols are horrifying. A young student in chemistry might as soon learn Hebrew as make himself acquainted with them ... They appear to me equally to perplex the adepts in science, to discourage the learner, as well as to cloud the beauty and simplicity of the atomic theory. — John Dalton

If, as I have reason to believe, I have disintegrated the nucleus of the atom, this is of greater significance than the war.
[Apology to the international anti-submarine committee for being absent from several meetings during World War I.] — Ernest Rutherford

The mathematical framework of quantum theory has passed countless successful tests and is now universally accepted as a consistent and accurate description of all atomic phenomena. — Erwin Schrodinger

Realizing its fundamental importance in understanding spectral lines, in atomic physics and in the theory of how light and electrons interact, quantum electrodynamics, Pauli and Heisenberg were determined to derive it from quantum theory rather than introducing it from the start. They believed that if they could find a version of quantum electrodynamics capable of producing the fine structure constant, it would not contain the infinities that marred their theories. — Arthur I. Miller
