Einstein s theory of relativity

Another design for particle accelerators is based on a circular arrangement. A cyclotron is similar to a linear accelerator wound into a spiral. A series of electromagnets causes the particles to move in a circle as they are accelerated by the electric field. According to Einstein s theory of relativity, an object s mass increases as it accelerates. In particle accelerators this is a problem because as the mass increases, the particle slows down and becomes out of sync with the changing electric field. A synchrotron is a cyclotron in which the electric field increases to compensate for the change in... [Pg.253]

In 2001, Christian Bok published Eunoia, which includes five chapters, each one of which is a prose poem using words with only one of the five vowels. Eunoia is also the shortest word in the English language to use all five vowels. More recently, Brian Raiter wrote a paper titled Albert Einstein s Theory of Relativity in Words of Four Letters or Less —an explanation of Albert Einstein s Theory of Relativity using words no more than four letters long, with paragraphs like ... [Pg.64]

This attempt to incorporate the spin of the electron, by using a halfintegral quantum number in a theory which seems to require integral values appears very artificial. It does nevertheless agree with the experimental observations. In 1928, Dirac developed a theory of the electron wavefunction which incorporated the principles of Einstein s theory of relativity. Very remarkably, the spin appears as a natural prediction of that theory, although the mathematical details are much too complicated to discuss here. [Pg.77]

At least within the constraints of Einstein s theory of relativity and the speed of light. [Pg.167]

Another principle that we use with impunity in chemistry is conservation of mass. Since Lavoisier, mass balance has been assumed in considerations of chemical transformations, even though Einstein s theory of relativity assures us that it is only an approximation. The point is that in chemistry and other fields that consider only relatively low-energy phenomena, conservation of mass is a very good approximation indeed ... [Pg.15]

It is important to recognize that scientific practice is not always this systematic. Discoveries have been made that are serendipitous and others have not started with the observation of data. Einstein s theory of relativity started with an intellectual and enquiring mind. [Pg.1]

Einstein s theory of relativity deals mainly with large scale phenomena but some of the results which follow from it are of fundamental importance for the theory of electrons and other particles. We shall therefore consider this theory briefly here. [Pg.83]

Einstein s theories of relativity were created during the early years of the twentieth century. The desire to confirm the many predictions of relativity has been one motivation in the search for ever more accurate clocks. The hydrogen maser clock is a part of that tradition. [Pg.186]

The answers to these questions can be found in the work of Albert Einstein. As we discussed in Section 12.2, Einstein s theory of relativity showed that energy should be considered a form of matter. His famous equation,... [Pg.994]

Our work has certainly had a strong societal impact, but this may in fact have delayed the Nobel Prize. Some may have thought that our research was too relevant, too applied. However, what is applied to some is fundamental to others. There are still people who doubt the validity of our claims in spite of all the hard evidence, but remember how many years it took Einstein s theory of relativity to get universally accepted. I am, of course, not comparing myself with Einstein. [Pg.464]

Michelson interferometer—An instrument designed to divide a beam of visible light into two beams which travel along different paths until they recombine for observation of the interference fringes that are produced. Interferometers are used to make precision measurements of distances. Special relativity—The part of Einstein s theory of relativity that deals only with nonaccelerating (inertial) reference frames. [Pg.331]

Theory A theory is an explanation that has been supported by many, many experiments. You may have heard of Einstein s theory of relativity or the atomic theory. A theory states a broad principle of nature that has been supported over time. All theories are still subject to new experimental data and can be modified. Also, theories often lead to new conclusions. [Pg.13]

Mother already had taught me that beyond surface differences, everything is [connected]. It seemed natural for the atom to be part of this connection. At school, when I was introduced to Einstein s theory of relativity—that energy and matter are one—I accepted the concept easily. [Pg.28]

In the context of Einstein s theory of relativity, we must ask whether Maxwell s expression of the electromagnetic theory is the most general representation consistent with the symmetry requirements of relativity. The answer is negative because the symmetry of Maxwell s equations based on reducible representations of the group of relativity theory. Then there must be additional physical predictions that remain hidden that would not be revealed until the most general 0irreducible) expression of the electromagnetic field theory is used. [Pg.685]

Let us now sum up the generalization of electromagnetic field theory thus far. The starting point is that the symmetry group that underlies Einstein s theory of relativity is a Lie group—a group of continuous, analytic transformations that preserve the covariance of all the laws of nature. This is the rule that all laws of nature remain in one-to-one correspondence in all continuously connected... [Pg.691]

After three years in the Pittsburgh area, Trumpler moved to the Lick Observatory, affiliated with the University of California. One of his most important assignments at the Lick was a test of Einstein s theory of relativity, conducted in the fall of 1922. By detecting the deflection of light around the limb (circumference) of the Sun, Trumpler was able to provide the first experimental proof for Einstein s theory. [Pg.31]

But what of scientific revolutions that we have come to expect Many thinkers at the end of the nineteenth century, and even shortly before Einstein s theory of relativity, and the rise of quantum theory on which modem electronics, IT, and computational medicinal chemistry depend, were predicting the end of scientific surprises. But it is in the nature of surprises that they are not to be expected. The world of biology may still hold many fundamental surprises, and still unveils one to us every so often. It was only recently that a new world of RNA control emerged in molecular biology, catching many by surprise (remember the basic biology—DNA makes RNA makes proteins). [Pg.131]

E = me2, perhaps the most famous equation of the last century, which most people believe has to do with Einstein s theory of relativity, but in actuality has nothing to do with it. This equation is founded on the basis that matter and energy are really different forms of the same thing and states that that the amount of energy (E) that could be produced is equal to the mass (m) of an atom times the speed of light (c) squared. [Pg.1]

So far we have discussed nonrelativistic ab initio methods they ignore those consequences of Einstein s theory of relativity that are relevant to chemistry (section 4.2.3). These consequences arise in the special (rather than the general) theory, from the dependence of mass on velocity [4. This dependence causes the masses of the inner electrons of heavy atoms to be significantly greater than the electron rest mass since the Hamiltonian operator in the Schrodinger equation contains the electron mass (Eqs (5.36) and (5.37)), this change of mass should be taken into account. Relativistic effects in... [Pg.229]

These observations can be accounted for (though often far from simply) if Einstein s theory of relativity is combined with quantum mechanics, in which case they are attributed to relativistic ejfects. We focus here on chemical generalizations. [Pg.298]
