This paper attempts to photons and known according to the axiom of the definition, using simple logic, reasoning about propositions of photons and its movement in space.The light is by the space motion photon component. The space motion photon has the energy and the quality. Photon in space along straight line direction movement speed identically equal in c. A photon moves in space with uniform helical motion, which is a combination of uniform circular motion and uniform linear motion in which the speed of the linear motion and the linear speed of the circular motion are always equal to c. Photon's Planck energy formula E=hv=2π v, is the approximate Planck constant, which is the angular momentum of photons moving along the circumference plane direction mcr, r is the photon along the circumference plane motion radius; v is photon each second completes the circular motion by link speed c the number of times c/2πr, also is the photon frequency. By replacing the mcr and c/2πr with the Planck energy formula, may obtain Einstein mass energy formula E=mc2.The greater its mass and energy, the smaller the radius of its circular motion, the higher its frequency, and the shorter its wavelength. The lower its mass and energy, the greater the radius of its circular motion, the lower its frequency, and the longer its wavelength. The uncertainty principle is essentially caused by our misunderstanding of the motion of light. The existence and motion of light can be determined.

A simple form of spin-surface is investigated and it is shown how, via this surface, spatial mechanisms may readily be synthesized to give twelve-point straight line motion or twelve-point circular motion. The spatial mechanisms are obtained by adding links to plane four-bar linkages.

The special honing machine is used in the precision machine of the monomer hydraulic prop cylinder internal hole surface. The main revolving movement is driven by motor, the reciprocating linear motion is actuated by hydraulic ram. Honing machine consists of three parts, mechanism, the hydraulic system and the electric control system. The work principle and the processing process, the interlock relation between movements and the straight line feed motion velocity modulation method of this machine were discussed in this study. The special honing machine designed for the monomer hydraulic prop cylinder is convenient and easy for person to operate, and has high efficiency. The reciprocating linear motion driven by hydraulic ram is steady when direction is changed. It is convenient to change speed, and has advantageous of enhancement processing surface quality.

Straight Line Mechanism

Small precise robotic devices, working on principle of compact compliant mechanisms, must meet the conditions to high positioning accuracy what mean moving in straight-line too. But, compliant mechanisms are usually produced by equivalent of revolute joints, therefore in design of small robotic devices is necessary apply knowledge from design of one type of specialized mechanisms – straight-line mechanisms. This paper presents some straight-line mechanism and its applications to design of some small precise robotic devices. According to kinematics analysis most known straight-line mechanisms are evaluated for their application in compliant mechanisms. Such devices are transformed to flexure structures. Consequently, these devices are important building blocks to design some linear-motion stages and/or micro-grippers.

The Law

The remarkable developments in Galileo's theory of motion revealed by his letter to Guidobaldo del Monte in 1602 have never been easy to account for in view of the almost complete lack of direct evidence. By examining the nature of the empirical evidence for the new ideas he advanced in 1602 and his earliest writings on motion in De motu, it is argued that the source of this transformation was his Copernican beliefs. There exists evidence that those beliefs led him to start work on his theory of the tides by 1595, and by 1597 to state to Kepler that Copernicanism had allowed him to account for many otherwise inexplicable phenomena. These comments very probably related to his new study of rotary and linear motion, linked to his theory of circular fall, which it is argued was devised at this point, and to an investigation of the pendulum. Such an investigation would account for his new interest in isochronism and his discovery of the link between linear and circular motion and to the two laws of isochronism announced to Guidobaldo in 1602: that of the pendulum and the law of chords.

Two Parameter

A tangent-plane undergoing two-parameter motion envelopes a surface called the tangent-plane envelope. Such surfaces can be considered as the envelope of a two-parameter family of planes or ∞2 family of planes. The properties of the tangent-plane motion are characterized through the properties of the spherical image of the normal to the surface it envelopes. This paper presents a methodology to locate a family of planes that envelope surfaces with similar characteristics.

Difficulty Walking

Neurovestibular symptoms experienced by astronauts in the post-flight period were examined using data from medical debriefs contained in the NASA Longitudinal Study of Astronaut Health database. Ten symptoms were identified (clumsiness, difficulty concentrating, persisting sensation aftereffects, nausea, vomiting, vertigo while walking, vertigo while standing, difficulty walking a straight line, blurred vision, and dry heaves), of which eight were crossed with twelve demographic parameters (mission duration, astronaut gender, age, one-g piloting experience, previous space flight experience, g-suit inflation, g-suit deflation, in-flight space motion sickness, in-flight exercise, post-flight exercise, mission role, fluid loading). Three symptoms were experienced by a majority of subjects, and another two by more than a quarter of the subjects. Intensity of the symptoms was mild, suggesting that they are unlikely to pose a risk to the crew during landing and the post-flight period. Seven of the symptoms and eight of the parameters under study were found to be significantly associated with each other.

Vehicle Mass

In this paper, it is deduced the ordinary differential equation that results in angle variation between the vehicle mass centre rate and the vehicle fore-aft axis. There are presented the wheels turning angles variations dependent on the angle that gives the vehicle orientation on trajectory. There are studied the following cases: the transfer from linear to circular motion, the transfer from circular to linear motion and the movement amidst poles. For each of these motions, there are presented the vehicle orientation angle variations on trajectory for three distinct rates. It is also presented the travelling rate influence on how the vehicle is situated on trajectory.

Force Displacement

A new fully compliant linear-motion mechanism, called the XBob, is presented. The mechanism is based on the pseudo-rigid-body model (PRBM) of a system of Roberts approximate straight-line mechanisms combined in series and parallel. It can be fabricated in a single plane and has a linear force-displacement relationship. Symmetry and compliance compensate for the structural error inherent in the Roberts mechanism, resulting in precise straight-line motion. The device is designed and its motion and force-displacement relations are predicted by the PRBM. The design is validated using finite element analysis and experimental results.
