Supergiants occur in every spectral class from young blue class O supergiants stars to highly evolved red class M supergiants.

Supergiants are among the most massive stars.

I think I have a way so we can carry on without his suspecting us ''.

`` If you can conveniently let me have twenty dollars '', he wrote one friend in 1791 when he was Secretary of the Treasury.

We have staved off a war and, since our behavior has involved all these elements, we can only keep adding to our ritual without daring to abandon any part of it, since we have not the slightest notion which parts are effective.

But now we can keep it out no longer, because we have come into a time when `` it invades our experience at every moment.

indeed, it is maintained that the sexual element in jazz, by freeing the listener of his inhibitions, can have therapeutic value.

All such imitations of negative quality have given rise to a compensatory response in the form of a heroic and highly individualistic humanism: if man can neither know nor love reality as it is, he can at least invent an artistic `` reality '' which is its own world and which can speak to man of purely personal and subjective qualities capable of being known and worthy of being loved.

This is an unsolved problem which probably has never been seriously investigated, although one frequently hears the comment that we have insufficient specialists of the kind who can compete with the Germans or Swiss, for example, in precision machinery and mathematics, or the Finns in geochemistry.

We hear equally fervent concern over the belief that we have not enough generalists who can see the over-all picture and combine our national skills and knowledge for useful purposes.

But, for practical purposes, we have people who can be considered as such.

Men continuously at the head of growing enterprises can acquire experiences of the most varied, complicated and trying type so that at maturation they have developed the competence and willingness to accept the personal responsibility so sorely needed now.

Only recently, and perhaps because a television debate can so effectively dramatize President Kennedy's extraordinary mastery of detail, have the abilities on which the capacity for making distinctions depend begun to be clearly discernible at the level of politics.

This means that the inception of change itself can begin only when the factors conducive to change have already become more powerful than those anchoring the existent form in being.

Without saying or seeming to say that in portraying the Sartoris and the Compson families Faulkner's chief concern is social criticism, we can say nevertheless that through those families he dramatizes his comment on the planter dynasties as they have existed since the decades before the Civil War.

If our sincerity is granted, and it is granted, the discrepancy can only be explained by the fact that we have come to believe hearsay and legend about ourselves in preference to an understanding gained by earnest self-examination.

We feel uncomfortable at being bossed by a corporation or a union or a television set, but until we have some knowledge about these phenomena and what they are doing to us, we can hardly learn to control them.

The men who speculate on these institutions have, for the most part, come to at least one common conclusion: that many of the great enterprises and associations around which our democracy is formed are in themselves autocratic in nature, and possessed of power which can be used to frustrate the citizen who is trying to assert his individuality in the modern world ''.

I still have the dress, and I hope to give it to the Smithsonian Institution as a memento, or, as I more fondly hope, to present it to a museum containing articles showing the daily lives of the Presidents -- if I can get it organized.

Conventional images of Jews have this in common with all perceptions of a configuration in which one feature is held constant: images can be both true and false.

Certainly one of the most important comments that can be made upon the spiritual and cultural life of any period of Western civilization during the past sixteen or seventeen centuries has to do with the way in which its leaders have read and interpreted the Bible.

`` Mr. Lane '', Hearst said, `` if you ever wish anything that I can do, all you will have to do will be to send me a telegram asking, and it will be done ''.

In my experience the assurance of forgiveness comes only when I have confessed to the wronged one and have made as full reparation as I can devise.

As long as his material is Americana, can in some way be ascribed to the masses and appears `` democratic '' to his audience, he remains satisfied.

For conspiracy theorists, the masses are a brainwashed herd, while the conspiracy theorists in the know can congratulate themselves on penetrating the plotters ' deceptions.

Gravity always acts in attraction, drawing two masses together, while the electric field can result in either attraction or repulsion.

Alternatively entropy can be defined from a classical thermodynamics viewpoint, in which the molecular interactions are not considered and instead the system is viewed from perspective of the gross motion of very large masses of molecules and the behavior of individual molecules is averaged and obscured.

He contended that the amount of moisture which the air can retain in solution increases with temperature, and, therefore, that on the mixture of two masses of air of different temperatures a portion of the moisture must be condensed and appear in visible form.

Or rather, such free initiative can only arise and develop by the masses ridding themselves of the ‘ authoritarian prejudices ’ by means of which the state reproduces itself in its primary function of representation and delegation.

" For these socialists, “ The intuition of the masses in action can have more genius in it than the work of the greatest individual genius ”.

Ringworld's Children reveals that there is life in hyperspace around gravity wells and that hyperspace predators eat spaceships which appear in hyperspace close to large masses, thus explaining why a structure as large as the Ringworld can safely engage the hyperdrive in a star's gravity well.

Unlike the booths, the disks do not require an enclosed chamber, and somehow can differentiate between solid masses and air, for example.

The ratio of the masses of oxygen that can react with 100 grams of carbon is 266: 133 ≈ 2: 1, a ratio of small whole numbers.

The molecular mass can be calculated as the sum of the individual isotopic masses ( as found in a table of isotopes ) of all the atoms in any molecule.

Morphogenesis can take place also in a mature organism, in cell culture or inside tumor cell masses.

* a mixture of known mole fraction can be prepared by weighing off the appropriate masses of the constituents

The mole fraction can be calculated from the masses and molar masses of the components:

To this Newtonian approximation, for a system of two point masses or spherical bodies, only influenced by their mutual gravitation ( the two-body problem ), the orbits can be exactly calculated.

The largest clusters can have 10 < sup > 4 </ sup > solar masses, with the massive cluster Westerlund 1 being estimated at 5 × 10 < sup > 4 </ sup > solar masses ; close to that of a globular cluster.

Grieve stated, " I can see the muscle masses in the appropriate places ...

An enormous diversity of musical styles and genres flourished during the Renaissance, and can be heard on commercial recordings in the 21st century, including masses, motets, madrigals, chansons, accompanied songs, instrumental dances, and many others.

Towards the end of the 15th century, polyphonic sacred music ( as exemplified in the masses of Johannes Ockeghem and Jacob Obrecht ) had once again become more complex, in a manner that can perhaps be seen as correlating to the stunning detail in the painting at the time.

Extremely massive stars ( more than approximately 40 solar masses ), which are very luminous and thus have very rapid stellar winds, lose mass so rapidly due to radiation pressure that they tend to strip off their own envelopes before they can expand to become red supergiants, and thus retain extremely high surface temperatures ( and blue-white color ) from their main sequence time onwards.

By heating hydrogen balloons, large masses can be suspended underneath at roughly Earth gravity.

Cold air masses arriving over the mountains in winter can lead to significant snowfalls, such as the Blizzard of 1996 and winter storms of 2009 – 2010.

* Classical mechanics: The laws of classical mechanics can be said to emerge as a limiting case from the rules of quantum mechanics applied to large enough masses.
