`` For Christ's sake, don't waste your powder on one of 'em ''!!

For several weeks we eyed one another almost like sparring partners, and then one day Uncle was slightly indisposed and stayed home ; ;

For one thing, this is not a subject often discussed or analyzed.

For one thing, there is a natural belt of rock across the river bed ; ;

For one thing, the world that Beckett sees is already shattered.

For the occasion on which everyone already knows everyone else and the host wishes them to meet one or a few honored newcomers, then the `` open house '' system is advantageous because the honored guests are fixed connective points and the drifting guests make and break connections at the door.

For this change is not a change from one positive position to another, but a change from order and truth to disorder and negation.

For paradigmatic history `` breaks '' rather than unfolds precisely when the movement is from order to disorder, and not from one order to a new order.

For innocence, of all the graces of the spirit, is I believe the one most to be prayed for.

For what we propose, however, a psychoanalyst is not necessary, even though one aim is to enable the reader to get beneath his own defenses -- his defenses of himself to himself.

For a freshman Congressman to read political Lessons to graybeard Democrats was poor policy for one who needed to make friends.

For this reason, then, poetry tends to weaken the power of control, the reason, because it tempts one to indulge his passions, and even the best of men, he maintains, may be corrupted by this subtle influence.

For one thing, Aristotle mentions that plays may corrupt the audience.

For by now the original cause of the quarrel, Philip's seizure of Gascony, was only one strand in the spider web of French interests that overlay all western Europe and that had been so well and closely spun that the lightest movement could set it trembling from one end to the other.

In his recent book, Hurray For Anything ( 1957 ), one of the most important short poems -- and it is the title poem for one of the long jazz arrangements -- is written for recital with jazz.

For the sad truth is that while one might write well without having read Bartleby The Scrivener, one is more likely, to write well if one has `` read it, and much else.

For one thing, there wasn't going to be any ceremony at all this year.

For a few brief minutes they had all been part of one little drama.

For that is the one an increasingly large number of prominent Americans are now proposing.

For discouragement, or the temptation to abandon our efforts, `` would show that one placed excessive trust in purely human means without thinking of the omnipotence of God, the irresistible efficacy of prayer, the action of Christ or the power of the Divine Spirit ''.

For more details of this early work, see Alpha particle # History of discovery and use.

For the case of an object that is small compared with the radial distance to its axis of rotation, such as a tin can swinging from a long string or a planet orbiting in a circle around the Sun, the angular momentum can be expressed as its linear momentum,, crossed by its position from the origin, r. Thus, the angular momentum L of a particle with respect to some point of origin is

For example, it also predicts the variation of the particle density in a gravitational field with height, if.

For example, the probability that an alpha particle striking a beryllium target will produce a neutron can be expressed as the equivalent cross section of beryllium for this type of reaction.

For example, if we suppose at t = 0 the extension is a unit distance ( x = 1 ), and the particle is not moving ( dx / dt = 0 ).

For mathematical purposes, elementary particles are normally treated as point particles, although some particle theories such as string theory posit a physical dimension.

The red dot overtakes two green dots when moving from the left to the right of the figure. New waves seem to emerge at the back of a wave group, grow in amplitude until they are at the center of the group, and vanish at the wave group front. For surface gravity waves, the water particle velocities are much smaller than the phase velocity, in most cases.

For a free non-relativistic particle it follows that

For non-interacting particles, i. e. particles which do not interact mutually and move independently, the potential of the system is the sum of the separate potential energy for each particle, that is

For instance, if a particle is in a state | ψ ⟩, the probability of finding it in a region of volume d < sup > 3 </ sup > x surrounding some position x is

For a single particle, this quantity is the rest mass ; for a system of bound or unbound particles, this quantity is the invariant mass.

For example, in a collision of two particles a reference frame can be chosen where one particle begins at rest.

For example, one can talk about motion of a wave or a quantum particle ( or any other field ) where the configuration consists of probabilities of occupying specific positions.

For example, mā ( high level pitch ) means " mom ", má ( rising pitch ) means " hemp ", mǎ ( falling then rising ) means " horse ", mà ( falling ) means " scold ", and ma ( neutral tone ) is an interrogative particle.

For example, a single photon may be refracted by a lens or exhibit wave interference with itself, but also act as a particle giving a definite result when its position is measured.

The red dot overtakes two green dots when moving from the left to the right of the figure. New waves seem to emerge at the back of a wave group, grow in amplitude until they are at the center of the group, and vanish at the wave group front. For surface gravity waves, the water particle velocities are much smaller than the phase velocity, in most cases.

For example, the free particle in the previous example will usually have a wavefunction that is a wave packet centered around some mean position x < sub > 0 </ sub > ( neither an eigenstate of position nor of momentum ).

For example, a single electron in an unexcited atom is pictured classically as a particle moving in a circular trajectory around the atomic nucleus, whereas in quantum mechanics it is described by a static, spherically symmetric wavefunction surrounding the nucleus ( Fig.

For example, consider a free particle.

For instance, the fundamental observables associated with the motion of a single quantum mechanical particle are the position and momentum operators and.

For example, the 3-particle state with one particle in state and two in state is

For the case of light alpha particles scattering off heavy nuclei, as in the experiment performed by Rutherford, the reduced mass is essentially the mass of the alpha particle and the nucleus off of which it scatters is essentially stationary in the lab frame.

For head on collisions between alpha particles and the nucleus, all the kinetic energy of the alpha particle is turned into potential energy and the particle is at rest.
