If the observer in S sees an object moving along the x axis at velocity w then the observer in the S' system will see the object moving with velocity w' where . This equation can be derived from the space and time transformations above. Notice that if the object is moving at the speed of light in the S ...

Introductory physics courses and some older textbooks on special relativity sometimes define a relativistic mass which increases as the velocity of a body increases. According to the geometric interpretation of special relativity, this is often depreciated and the term 'mass' is reserved to mean 'rest mass' and is thus independent of the inertial frame, i.e., invariant. Using the relativistic mass definition, the mass of an object may vary depending on the observer's inertial frame in the same way that other properties s ...

Mario Rodríguez Cobos, also known as Silo, was born in 1938 and lives in Mendoza, Argentina. As the author of many books, he received an honorary doctorate from the National Academy of Sciences of Russia in October 1993. In 2001, in the Annual Ordinary Meeting of the Assembly of General Coordinators, the highest level of interchange for those involved in the organisational structure, in Madrid, Spain, Silo announced his retirement from the affairs of the Humanist Movement, leaving all further development in the hands of this ...

The history of the Humanist Movement has not been without its conflict with other organisations and individuals. During the 60's as the initial groups were forming with the name "Young Power" many problems existed with the Catholic Church in Argentina. The organisation being clearly anti the military regime in place in Argentina at that time also came under attack from the government with many people arrested and put i ...

The fundamental concept of musical set theory is the (musical) set. A set is a collection of any musical materials or qualities (such as pitch classes or rhythms), ordered or unordered, although most often sets of pitch classes are considered. The elements of a set may be simultaneous or successive events, or both. A set is indicated by being enclosed in brackets: {}, an ordered set is indicated by <>, and an unordered set by (). Thus the set of pitch classes 0, 1, and 2 is {0,1,2}, the ...

New Humanism is based on two basic points: Solidarity – defined as treating other people the way one would like to be treated and, Coherence – defined as thinking, feeling and acting in the same way. The project of the Humanist Movement is to eradicate war, hunger, poverty and economic exploitation across the planet and develop a new system based on the value of human life as the central value, higher than money, power, prestige, etc. This vision of the future is called the Universal Human NationSee also:

Near the end of the 60s, Silo organized a group to study the personal and social crisis occurring in the world. This group, and others like it, organized around his writings, grew and developed into what later became known as the Humanist Movement. The Humanist Movement is often said to have been started on May four, 1969 with the talk "The Healing of Suffering" by Silo at Punta de Vacas, Argentina. Because of the military dictatorship in place at that time this talk was permitted on the condition that it would be held high in th ...

The number of times which a set may be mapped onto itself through different operations is its degree of symmetry. Every set has at least one degree of symmetry, as it maps onto itself under the identity operation T0. Transpositional symmetry is the property of set which maps onto itself for Tn where n does not equal 0. Inversional symmetry is the property of a set which maps into itself under TnI. For any given Tn/TnI type all sets will have the ...

In addition to modifying notions of space and time, special relativity forces one to reconsider the concepts of mass, momentum, and energy, all of which are important constructs in Newtonian mechanics. Special relativity shows, in fact, that these concepts are all different aspects of the same physical quantity in much the same way that it shows space and time to be interrelated. There are a couple of (equivalent) ways to define momentum and energy in SR. One method uses conservation laws. If these laws are to remain valid in SR they ...

SR uses a 'flat' 4-dimensional Minkowski space, which is an example of a space-time. This space, however, is very similar to the standard 3 dimensional Euclidean space, and fortunately by that fact, very easy to work with. The differential of distance(ds) in cartesian 3D space is defined as: where (dx1,dx2,dx3) are the differentials of the three spatial dimensions. In the geometry of special relativity, a fourth dimension, time, is added, with units of c, so that the equati ...

In diagram 2 the interval AB is 'time-like'; i.e., there is a frame of reference in which event A and event B occur at the same location in space, separated only by occurring at different times. If A precedes B in that frame, then A precedes B in all frames. It is hypothetically possible for matter (or information) to travel from A to B, so there can be a causal relationship (with A the cause and B the effect). The interval AC in the diagram is 'space-like'; i.e., there is a frame of reference in which event A and event ...

Special relativity holds that events that are simultaneous in one frame of reference need not be simultaneous in another frame of reference. Simultaneity can be seen by considering the second term of the expanded Lorentz equation for t'. Here as the velocity v varies two events move forwards or backwards in time relative to each other if they are physically separated in space. This can be observed in Diagram 1; some events may be observed moving from the past to the future and back again as accelerati ...

Main article: Consequences of Special Relativity Special relativity leads to different physical predictions than Galilean relativity when relative velocities become comparable to the speed of light. The speed of light is so much larger than anything humans encounter that some of the effects predicted by relativity are initially counter intuitive. The time lapse between two events is not invariant from one observer to another, but is dependent on the relative speeds of the observers' reference frames. (See Lorentz t ...

Multiplying through we get: Examination of the first term of the equation for x' in the Lorentz transformation shows that all positions x in one frame are multiplied by gamma, a number greater than one, to calculate the spatial interval in the second comoving frame.
