The atomic bomb certainly is the most powerful of all weapons, but it is conclusively powerful and effective only in the hands of the nation which controls the sky.
Interpretation
The atomic bomb's effectiveness is dependent on the control of the airspace above.
In this quote, Lyndon B. Johnson emphasizes that while the atomic bomb is a formidable weapon, its true power is realized only when a nation possesses and maintains aerial superiority. This highlights the importance of strategic military advantages beyond just having powerful weaponry.
In practice
In a speech about military strategy, one might reference this quote to illustrate the importance of maintaining dominance in the air.
You do not take a person who, for years, has been hobbled by chains and liberate him, bring him up to the starting line of a race and then say, "you are free to compete with all the others," and still justly believe that you have been completely fair. We seek not just legal equity but human ability, not just equality as a right and a theory but equality as a fact and equality as a result.
Peace is a journey of a thousand miles and it must be taken one step at a time.
We do this in order to slow down aggression. We do this to increase the confidence of the brave people of South Vietnam who have bravely born this brutal battle for so many years with so many casualties. And we do this to convince the leaders of North Vietnam-and all who seek to share their conquest-of a simple fact: We will not be defeated. We will not grow tired. We will not withdraw either openly or under the cloak of a meaningless agreement.
So far are we generally from thinking what we often say of the shortness of life, that at the time when it is necessarily shortest we form projects which we delay to execute, indulge such expectations as nothing but along train of events can gratify, and suffer those passions to gain upon us which are only excusable in the prime of life.
You do not examine legislation in the light of the benefits it will convey if properly administered, but in the light of the wrongs it would do and the harms it would cause if improperly administered.
If government is to serve any purpose it is to do for others what they are unable to do for themselves.
We cannot fathom the marvelous complexity of an organic being; but on the hypothesis here advanced this complexity is much increased. Each living creature must be looked at as a microcosm--a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven.
Science itself is badly in need of integration and unification. The tendency is more and more the other way ... Only the graduate student, poor beast of burden that he is, can be expected to know a little of each. As the number of physicists increases, each specialty becomes more self-sustaining and self-contained. Such Balkanization carries physics, and indeed, every science further away, from natural philosophy, which, intellectually, is the meaning and goal of science.
Equipped with our five senses - along with telescopes and microscopes and mass spectrometers and seismographs and magnetometers and particle accelerators and detectors sensitive to the entire electromagnetic spectrum - we explore the universe around us and call the adventure science.
The black holes of nature are the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time.
Mathematics is the tool specially suited for dealing with abstract concepts of any kind and there is no limit to its power in this field.
Today, all physicists know from studying Einstein and Bohr that sometimes an idea which looks completely paradoxical at first, if analyzed to completion in all detail and in experimental situations, may, in fact, not be paradoxical.
