One of the key concepts in chemistry is that all chemical compounds can be described as groups of atoms bonded together and chemical reactions can be described as the making and breaking of those bonds.

One particularly important consequence of the principle is the elaborate electron shell structure of atoms and the way atoms share electrons, explaining the variety of chemical elements and their chemical combinations.

One mechanism by which high energy neutrons ionize atoms is to strike the nucleus of an atom and knock the atom out of a molecule, leaving one or more electrons behind as the chemical bond is broken.

One of the most important features of chemical synapses is that they are the site of action for the majority of psychoactive drugs.

One possibility is that the chemical peculiarity may be the result of diffusion or mass loss, although stellar models show that this would normally only occur near the end of a star's hydrogen-burning lifespan.

One can determine the chemical amount of a known substance, in moles, by dividing the sample's mass by the substance's molar mass.

One advantage of magnetic or solar sails over ( chemical or ion ) reaction thrusters is that no reaction mass is depleted or carried in the craft.

One design would generate 13 meganewtons of thrust at 66 km / s exhaust velocity ( compared to ~ 4. 5 km / s exhaust velocity for the best chemical rockets of today ).

One of the more bizarre guidance methods instead used a pigeon to steer the missile to its target.

One was an extremely free translation ( or rather a paraphrase ) of The Protreptic of Galen ( Paraphrase de C. GALIEN, sus l ' Exhortation de Menodote aux estudes des bonnes Artz, mesmement Medicine ), and in his so-called Traité des fardemens ( basically a medical cookbook containing, once again, materials borrowed mainly from others ) he included a description of the methods he used to treat the plague – none of which, not even the bloodletting, apparently worked.

One book states that periodic abstinence was recommended " by a few secular thinkers since the mid-nineteenth century ," but the dominant force in the twentieth century popularization of fertility awareness-based methods was the Roman Catholic Church.

One of the most commonly used methods is spontaneous parametric down-conversion to generate a pair of photons entangled in polarisation.

One of the characteristics of artistic research is that it must accept subjectivity as opposed to the classical scientific methods.

One can create a class that does not define any methods other than and does not inherit from any other class.

One major tendency of the 1918 Russian communist left criticised the re-employment of authoritarian capitalist relations and methods of production.

One of Sprague's contributions to the Edison Laboratory at Menlo Park was to expand Edison's mathematical methods.

One of Edison's famous quotations about his attempts to make the light globe suggest that perhaps Tesla was right about Edison's methods of working: " If I find 10, 000 ways something won't work, I haven't failed.

One of the methods of dealing with non-equilibrium systems is to introduce so-called ' internal variables '.

One example of the clash of intellectual culture and Adorno's methods can be found in Paul Lazarsfeld, the American sociologist for whom Adorno worked in the middle 1930s after fleeing Hitler.

One of the newer methods developed for conducting a synchronous remote usability test is by using virtual worlds.
