He uses this as a proof of the existence of atoms:
The central claim is that all but the last element in such sequences are particles: Particles are the following 18 words: Some scholars would also add together; I have opted not to, because together can form a phrase only with the non-spatial Ptrue with; it never intervenes between a verb and a following PP to form a phrasal verb: Particles appear either before or after direct objects: Ptrue never follow their objects: The source P true from and the goal Ptrues to and until can precede one other Ptrue, but only in spatial PPs from by the sink to behind the bar or temporal PPs until after the fiesta.
When these 3 Ptrues are in non-spatial contexts, they cannot be followed by other Ptrues: Particles distinguished by boldface are found in the following three environments: The rules limiting the possible sequences of particles which will be boldfaced are incompletely understood.
The paper will present what can be said currently. The longest sequences seem to be three, for most speakers — here is a rare one of length four Drag it back up in around behind the stove. Many speakers balk even at three. I have no convincing example of five. Paths of length 3 are easy for me, anyway to make up, and are even findable via Google.
Iterative back and continuative on seem to be able to precede any spatial preposition except for: Further, I believe that a sequence of back followed by any other particle, will always be more acceptable that the same two particles in the opposite order.
However, there are macroconstituents called paths, such as the underlined one in 1: All three PP types are spatial, therefore particles can precede each of them, as shown in the parentheses. With enough contextual help, however, certain objects of spatial prepositions can be zeroed, as was observed in Fraser ; on the basis of examples such as 2: It may be possible to exceed in this way the four-particle limited posited in A, which thus should be reformulated as a limit on the number of particles which can precede any single P.
Let us call such a sequence of particles preceding P a local path. There are only rwo sure environments in which to try to construct the longest possible particle paths: Because if a sequence of particles follows a verb and precedes a PP as in Jump back out up in beside the throne.particle through six regions of uniform magnetic field, where the path is either Figure shows 11 paths through a region of uniform magnetic field.
One path is a straight line; the the frequency, and (c) the pitch of the particle’s motion,greatest first.

x t Possible paths which contribute to the action. In this case, the system consists of a single particle.
But –ui is related to –xi through ui= dxi=dt, so. All particle paths which precede a Ptrue seem stronger than ones which are all particles: Walk down out into the room >> *Walk down out.
Come in up to the office >> *Come in up. H. Some sequences of particle + Ptrue allow the (underlined) Ptrue to be deleted: Throw it . The combination of circular motion in the plane perpendicular to the magnetic field, and uniform motion along the direction of the field, gives rise to a spiral trajectory of a charged particle in a magnetic field, where the field forms the axis of the spiral--see Fig.

on a planet of mass m 2 (the probe), where r is the distance between their cen- ters and ˆr is a unit vector pointing away from the Sun (see Figure ). In a uniform electric field, the force on a charged particle is always in the same direction, leading to parabolic trajectories.
In a uniform magnetic field, the force of charged particles is always right angles to the motion, resulting the circular paths (or) helical trajectories.
