23. Weyl One of the first people to combine general relativity with the laws of electromagnetism http://www-groups.dcs.st-and.ac.uk/~history/Mathematicians/Weyl.html

Hermann Klaus Hugo Weyl Born: 9 Nov 1885 in Elmshorn (near Hamburg), Germany Died: Click the picture above to see eight larger pictures Show birthplace location Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Main index Hermann Weyl Hilbert . After submitting a doctoral dissertation He attempted to incorporate electromagnetism into the geometric formalism of general relativity. Weyl published (1913) which united analysis, geometry and topology . He produced the first guage theory in which the Maxwell electromagnetic field and the gravitational field appear as geometrical properties of space-time. From 1923-38 he evolved the concept of continuous groups using matrix representations . With his application of group theory to quantum mechanics he set up the modern subject. He also made contributions on the uniform distribution of numbers modulo 1 which are fundamental in analytic number theory More recently attempts to incorporate electromagnetism into general relativity have been made by John Wheeler, Kaluza and others. These theories, like Weyl's, lack the connection with quantum phenomena that is so important for interactions other than gravitation.

Electromagnetism is a theory unified by James Maxwell to explain the interrelationship between electricity and magnetism . At the heart of this theory is the notion of an electromagnetic field A stationary electromagnetic field stays bound to its origin. Examples of stationary fields are: the magnetic field around a current carrying wire or the electric field between the plates of a capacitor. A changing electromagnetic field propagates away from its origin in the form of a wave . These waves travel at the speed of light and can have a wide spectrum of frequencies and wavelengths . Examples of the dynamic fields of electromagnetic radiation (in order of increasing frequency): radio waves

29. Michael Faraday (1791-1867) Short biography focuses on the importance of Faraday's experiments with electromagnetism. http://www.iee.org.uk/publish/faraday/faraday1.html

Login or Register Shop Help Search ... Contacts Michael Faraday (Information provided by the IEE Archives department.) Michael Faraday's scientific work laid the foundations of all subsequent electro-technology. From his experiments came devices which led directly to the modern electric motor, generator and transformer. Faraday was also the greatest scientific lecturer of his day, who did much to publicise the great advances of nineteenth-century science and technology through his articles, correspondence and the Friday evening discourses which he established at the Royal Institution. The Royal Institution Christmas lectures for children, begun by Faraday, continue to this day. Michael Faraday was born on 22nd September 1791. At the age of fourteen he was apprenticed to a London bookbinder. Reading many of the books in the shop, Faraday became fascinated by science, and wrote to Sir Humphry Davy at the Royal Institution asking for a job. On 1st March 1813, he was appointed laboratory assistant at the Royal Institution. There Faraday immersed himself in the study of chemistry, becoming a skilled analytical chemist. In 1823 he discovered that chlorine could be liquefied and in 1825 he discovered a new substance known today as benzene. However, his greatest work was with electricity. In 1821, soon after the Danish chemist, Oersted, discovered the phenomenon of electromagnetism, Faraday built two devices to produce what he called electromagnetic rotation: that is a continuous circular motion from the circular magnetic force around a wire. Ten years later, in 1831, he began his great series of experiments in which he discovered electromagnetic induction. These experiments form the basis of modern electromagnetic technology.

Electromagnetism and Charge Mass is one attribute of matter. It is associated with the gravitational force Charge is another attribute of matter. It is associated with the electromagnetic force The theory of electromagnetism was first proposed by James C. Maxwell: Light is an electromagnetic wave. Matter can be electrically charged. A stationary charge has an electric field. A moving charge can produce a magnetic field. Just as gravity accelerates masses, electric and magnetic fields can accelerate charges. When accelerated, charges give off ( emit electromagnetic radiation

32. Essay On The Unified Theory Of The Classical Fields Of Gravitation And Electroma A new attempt to establish a unified theory of the classical fields of gravitation and electromagnetism which complies with the geometric paradigm of the theory of relativity of Albert Einstein. http://www.e-kr.org

Essay on the Unified Theory of the Classical Fields of Gravitation and Electromagnetism After the publication of the general theory of relativity in 1916, Albert Einstein tried to establish a unified theory of the classical fields of gravitation and electromagnetism. Although he published many attempts on the subject until 1955, it is sadly wise to say that he did not succeed. We would like to introduce a new attempt to establish a unified theory of the classical fields of gravitation and electromagnetism which complies with the geometric paradigm of the theory of relativity of Albert Einstein. The theory we shall describe is geometrically unified in the sense that the fields equations, and the Hamiltonian function from which they derive, are formally unified entities (i.e. they are not the sum of several independent parts) which depend only on the metric of the particular spacetime being considered.

Electromagnetism What is Electromagnetism? Electromagnetism describes the relationship between electricity and magnetism. Nearly everyone, at some time or another, has had the opportunity to play with magnets. Most of us are acquainted with bar magnets or those thin magnets that usually end up on refrigerators. These magnets are known as permanent magnets. Although permanent magnets receive a lot of exposure, we use and depend on electromagnets much more in our everyday lives. Electromagnetism is essentially the foundation for all of electrical engineering. We use electromagnets to generate electricity, store memory on our computers, generate pictures on a television screen, diagnose illnesses, and in just about every other aspect of our lives that depends on electricity. Electromagnetism works on the principle that an electric current through a wire generates a magnetic field. This magnetic field is the same force that makes metal objects stick to permanent magnets. In a bar magnet, the magnetic field runs from the north to the south pole. In a wire, the magnetic field forms around the wire. If we wrap that wire around a metal object, we can often magnetize that object. In this way, we can create an electromagnet.

Different movements this can be put into are then used to explain matter and radiation. An atom is composed of rotating energy which also precesses. Rotational energy given off are charge-pairs rotating in the plane of the direction of travel, i.e. end-over-end, and represent light, or photons. Precessional energy given off rotates at right-angles to the direction of travel (counterclockwise?), and represents neutrinos. If one considers a precessional rate of twice the rotation, one arrives at the Galaxy Pattern, which is completed by rings of sixteen members. Completing rings of sixteen members can be matched to the growth of the Periodic Table of the Elements. The Galaxy Pattern is composed of eight pathways, each of which can contain a maximum of two members from the ring: the two members exactly opposite each other and exactly the opposite of the other in movement and position."
