1869ref. 42029London Taylor & Francis 1869 Large 4to. Without wrappers. Extracted from "Philosophical Transactions of the Royal Society of London." Vol. 158. Maxwell's paper: pp. 643-657. Clean and fine wide margins. First appearance of this major paper on electromagnetic dynamics in which Maxwell improves the groundbreaking equations he had set forth in his famous paper of 1865 the "A dynamical Theory of Electro-Magnetic Fields". In the paper offered here he for the first time proposed to base the electromagnetic theory of light solely on 2 equations. The paper is one of Maxwell's 5 most importent contributions to electromagnetism."Formulas for the forces between moving charged bodies may indeed de derived from Maxwell's equations but the action is not along the line joining them and can be reconciled with a dynamical principle only by taking into account the exchange of momentum with the field. Maxwell remarked that the equations might be condensed but "to eliminate a quantity which expresses a useful idea would be rather a loss than a gain in this stage of our enquiry." he had in fact simplified the equations in his fifth major paper the short but importent "Note on the Electromagnetic Theory of Light." 1868 writing them in an integral form without the function A based on four postulates derived from electrical experiments. This may be called the electrical formulation of the theory in contrast with the original dynamical formulation." C.W.F. Everitt in DSB. unknown

In Valley of Shadows and Dreams they dig deep into the harsh truths of farm workers' daily experience revealing a deep sense of anger and betrayal toward the destructive legacies of politics bureaucracy and control. The Lights show us once-viable farmland transformed into neighborhoods full of empty tract homes that no workers can afford. We are confonted head-on with the devastating results of foreclosure. We stand in the Community Center food line in Mendota we slip magically onto a midnight dance floor with migrant workers in Tulare and we sail out across the San Joaquin River on a rope swing. These photos and stories capture scenes of hardworking people fighting to preserve their livelihoods and traditions. With an introduction by Thomas Steinbeck and impassioned essays by Melanie Light about the importance of recognizing and rectifying the cycle of employers oppressing workers Valley of Shadows and Dreams uncovers the realities of life in this troubled but vital region that are often hidden and difficult to capture. . 2012. 1597141720 .

With the Index and Privilege of Clemente VII. The dating is false; several editions of Machiavelli carry nominally earlier dates following their proscription by the Pope in the 1550s. General James St. Clair-Erskine, 2nd Earl of Rosslyn (1762-1837) was educated at Edinburgh High School and Eton, and commissioned in 21st Light Dragoons (one of the several early manifestations of the regiment; disbanded 1783) after which he pursued a distinguished military and political career. He succeeded his uncle to the Earldom in 1805, and was in the following year a member of the Mission to Lisbon which resulted in Wellington's Peninsular Campaign. He was appointed General in 1814, Lord Privy Seal (1829-30) and Lord President of the Council under Peel (1934-5). The Geneva 'testina' editions take their name from the 'little head' of the author carried on titles. Brunet, III, 1274; Gamba 623 (recording several variant printings).

Printed on various paper stocks with overlaid Japanese text throughout. Creasing and wear to corners of wraps; soiling and fading to rear cover; 3.5" closed tear from base of one leaf; the usual toning to textblock. Good to very good. A photobook telling the story of Argentine revolutionary Che Guevara 1928-1967 as compiled under the pseudonym Buenos no Hi The Light of Buenos by members of Japan's legendary avant-garde photography collective Provoke. Published in the immediate aftermath of the third issue of Provoke magazine the book's bold layout combines appropriated images with texts by and about Guevara. Provoke members Koji Taki and Takuma Nakahira were the work's principle compilers although Daido Moriyama was also reportedly involved in curating the photographs. A scarce and striking publication exemplary both of the gritty blown-out style Provoke has come to be revered for and of the revolutionary spirit that motivated their work.

Scarce first edition of Lorenz' landmark paper which contains his important studies on the electromagnetic theory of light in which he - less than two years after but independently of Maxwell - found that LIGHT MIGHT BE INTERPRETED AS ELECTROMAGNETIC WAVES and that his equations lead to the CORRECT VALUE FOR THE VELOCITY OF LIGHT. "The procedure which Lorenz followed was that of which Riemann had suggested in 1858 namely to modify the accepted formula of electrodynamics by introducing terms which though too small to be appreciable in ordinary laboratory experiments would be capable of accounting for the propagation of electrical effects through space with a finite velocity.The Lorenz- equations are however the fundamental equations of Maxwell's theory; and therefore the theory of L. Lorenz is practically equivalent to that of Maxwell so far as concerns the propagation of electromagnetic disturbances through free aether.he suggested that ALL LUMINOUS VIBRATIONS MIGHT BE CONSTITUTED BY ELECTRIC CURRENTS and hence that there was 'no longer any reason for maintaining the hypothesis of an aether since we can admit that space contains sufficient ponderable matter to enable the disturbance to be propagated" Edmund Whittaker in "A History of the Theories of Aether and Electricity I" p. 267-70. unknown
1934ref. 000530Borden Hants Hampshire England. Good. 1934. Original Wraps. On offer is a handwritten notebook-style instruction manual as titled on the cover "Fencing Lessons Foil - Sabre - Epee". The inside front cover has a pastedown fully identifying the writer: "Serjeant T. Wells of the 1st BATTALION OXFORDSHIRE & BUCKINGHAMSHIRE LIGHT INFANTRY. 19th Sept. to 13th Dec. 1934. Instructors Gartzen and Harkinson". An Index of the 67 page book shows that besides the lessons in the three sword types there are chapters on the Army Fencing Union Pitches and Arenas and Bayonet Team Competitions. We are led to believe that this book is also a manual for the Instructor trainee as most pages have three columns headed: Pupil Master Remarks. The remarks appear to be helpful hints for the Instructor in dealing with the pupil. There are a number of hand drawn illustrations including charts tables graphs and such plus there are quite a few little. 1.5" x 1" photographs which were cut from elsewhere and glued in as part of the lesson. In addition to the identification on the cover and inside front cover the back cover has Sjt. Wells handwritten address being we believe Bordon Hants Hampshire.

TINY NICK ON SPINE CVR It tells of a talking raven's mysterious visit to a distraught lover tracing the man's slow descent into madness. The lover often identified as being a student is lamenting the loss of his love Lenore. The raven sitting on a bust of Pallas the goddess of wisdom seems to further instigate his distress with its constant repetition of the word "Nevermore". The poem makes use of a number of folk and classical references. Poe claimed to have written the poem very logically and methodically.

Some scattered brownspots. First appearance of Fresnel's landmark papers on the phenomena of diffraction presenting Fresnel's first priinted paper on the subject. These two papers won the Academy's prize for 1818 and were later expanded and published as a long memoir in 1826. The first paper offered initiated the attack on the corpuscular theory of light which was completely owerthrown by a series of succesfull papers by Fresnel the next few years. In the second paper Fresnel summed up all his work prior to this date in completed form. The paper is called "extract" but the longer memoir was not published until 1826. The paper is A CLASSIC IN PHYSICS."In broad context Fresnel's work can be viewed as the first successfull assault on the theory of imponderables and a major influence on the development of nineteenth-centurty energetics." DSB V p. 171.Diffraction arises because of the way in which waves propagate; this is described by the Huygens-Fresnel principle. The propagation of a wave can be visualized by considering every point on a wavefront as a point source for a secondary radial wave. The subsequent propagation and addition of all these radial waves form the new wavefront. When waves are added together their sum is determined by the relative phases as well as the amplitudes of the individual waves an effect which is often known as wave interference. The summed amplitude of the waves can have any value between zero and the sum of the individual amplitudes. Hence diffraction patterns usually have a series of maxima and minima.
