"With regard to the formal structure of the tradition, we need not beat about the bush. In obvious ways the Islamic heritage lends itself so easily to fundamentalization that it could almost be said to invite it."

"There are several reasons why Muslims make good enemies in the Indian context. One is that Muslims, whether they like it or not, are historically identified with the invaders who did most to destroy Hindu culture. Of course, not all the Muslim elite in India espoused this program assiduously, and many did not pursue it at all or indeed did the opposite. But there was enough rhetoric of destruction, and enough actual destruction, to lend support to a deep sense of Hindu grievance."

"One is that, even before the rise of Islamism, there were indications that leftism did not in general fare as well in the Islamic world as it did in other Third World regions. There was a sense at the time that the presence of Islam displaced the political spectrum to the right. One effect of this was a certain opportunistic reticence on the part of leftists in the Islamic world when it came to the manifestation of antireligious sentiments."

"The situation of the Muslims of China was very different. They were geographically remote from the Muslim heartlands— in contrast to the Muslims of India, whose contacts were so close that to a large extent they transacted their affairs in Persian... The result was the appearance of a Muslim literature in Chinese that pressed the argument that Confucian and Muslim values were fully compatible, if not identical. Thus an inscription purportedly dating from 742, but likely to have been forged by Chinese Muslims in the Ming period, says of Confucius and Muḥammad that “their language differed, yet their principles agreed.”... Nor is Islamic-­Confucian syncretism likely to have cut much ice with the Chinese elite. One prominent Chinese Muslim author was able to persuade some Confucian scholars to write laudatory prefaces for his books, and the title of his heavily Confucianized work on Muslim ritual found a place in an imperial compendium of 1773–­1782. But the work was placed in the company of books that “contained little that was praiseworthy and much that was contemptible,” and an editorial comment, while conceding that the author’s literary style “is actually rather elegant,” maintained that “the clever literary ornamentation does him no good” for the simple reason that “Islam is fundamentally far-­fetched and absurd.”"

"Writing is a learned and practiced craft, not a work of magic or mystery. Indeed, the magic happens when you are practicing the craft. Literary talent may be distributed unevenly, but no one is “born” a writer."

"My hands-down favorite writer is my friend , and that's in large part because much of what I've learned about writing over the last couple of decades has come in the form of gifts from him. Carlo is an apostle of craft, skill, mastery, and work. He writes great prose, to be sure, but he has also taught me about blocking, outlining, editing, structure—all those things I pretended to do, but never actually did. Talking to Carlo, I am always reminded that craft itself produces ideas and insights, unbidden thoughts that transcend the nuts and bolts work. That's why we tell our students that writing is thinking, and that thinking may well be incomplete without writing."

"The culture hero of our business civilization was the self-made man, a man of action, not one of trained intellect."

"While appraising all aspects of the past, including myths, we must at the same time uphold the critical function that is the basis of all scholarship, indeed, of civilization itself. For this we also need to recognize clearly the sources of irrationality in history, in our culture, in ourselves."

"The ivory tower can become a pretty dull place, and rather unproductive, too."

"American respect for business, and the businessman's inadequate appreciation of the intellectual, have by tradition been pretty generally taken for granted. One historian has gone so far as to say that whenever business sits in the driver's seat, as it did in the 1920's and as it does today, the distrust of the intellectual is both epidemic and dominant."

"...There was also a feeling among many clergymen that scholarship somehow threatens religion. Even Jonathan Edwards, himself a profound scholar, took the colleges to task for failing to inculcate piety. The persistence of such a view is seen in the sustained effort of the nineteenth-century academic orators to refute the charge that learning and religion are at necessary odds. No note is more often struck than this in the hundreds of commencement orations and other academic addresses that I have had the somewhat doubtful pleasure of reading."

"The first American republic, created out of revolution in the late 18th century, was in effect destroyed. A new, second republic took its place, given a violent birth in the emancipation of four million slaves and the re-crafting of the U. S. Constitution in the 13th, 14th, and 15th Amendments. Those Amendments—ending legal slavery forever, sanctifying birthright citizenship and establishing “equal protection of the law,” and creating black male suffrage—in effect re-made the United States Constitution. This comprised a second American revolution."

"(everyone should read:) Prophet of Freedom by David W. Blight. Blight’s biography of Frederick Douglass is probably the best biography I have ever read. If you want to understand America, you have to understand Douglass. He is one of the true founding fathers of this country, someone who helped America see what it was, and who helped direct it towards what he believed it could one day be."

"A significant segment of American society hates the President [Barack Obama] and cannot seem to abide a black family living in the White House."

"The death toll, the sheer sense of human loss experienced in the war, North and South, among blacks and whites, left a profound and haunting pall on American society and culture for generations to come. The old, official count of Civil War dead relied upon for a century and a half was approximately 620,000. According to some remarkable new research, as many as 750,000 American soldiers and sailors may have died in the conflict, the majority from disease. Approximately 1.2 million were wounded, including perhaps 30-40,000 northern amputees (there are no equivalent numbers for Southerners) who struggled with life and livelihood well into the late nineteenth century. There is no reasonable count of civilian deaths, nor of the numbers of freed slaves who perished in the struggle for their own emancipation. Research now suggests that a quarter of all freedmen who made it to contraband camps operated by the Union forces died in the process. Based on the military death count alone, per capita, if the Civil War were fought in the United States today with its ten-fold greater population, 7.5 million soldiers would die. For most Americans that is an unthinkable toll, but such was the equivalence for their kinfolk in the 1860s. Whenever Americans have been compelled to face and understand experiences of great loss and suffering—the World Wars, the Great Depression, the attacks of 9/11—they have returned to the Civil War-era for touchstones of understanding."

"...These men and their party had overseen an unprecedented centralization of power in the federal government as a means of fighting and winning the Civil War. It is worth remembering, especially in America’s current political circumstances in the early 21st century, that these men of the first Republican Party vehemently believed in government."

"In at least three passages of the Rigveda mentioning the Sarasvatī, a river corresponding to the present Sarsuti and Ghaggar is meant. For this we have conclusive evidence in the famous hymn, the ‘Praise of the rivers’ (Nadistuti) which, with a precision unfortunately quite exceptional in Vedic texts, enumerates the Sarasvati correctly between the Yamuna (Jumna) in the east and the Sutudri or Sutlej in the west... ‘of old sites on its banks’ would ‘be helpful to the student of early Indian history, still so much obscured by the want of reliable records and the inadequacy of archaeological evidence.’"

"Stein was essentially a geographer and an explorer and is to be admired for his indomitable courage and spirit of adventure in undertaking hazardous journeys through difficult terrain. He discovered a large number of Chalcolithic and related sites in the Great Indian Desert and the entire reach of the Indo-Iranian borderlands, covering Northern and Southern Baluchistan and a good part of Iran. He was a pioneer and a pathfinder and was to Indian protohistoric archaeology what Alexander Cunningham was to Indian historical archaeology."

"The name Martanda, in the form of Mnrtand or Matan, still attaches to the ruins though they have long ago ceaaed to be an object of religious interest. King Kalasa had sought this great fane at the approach of death, and expired at the feet of the sacred image (a.d. 1089). Harsa, his son, respected this temple in the course of the ruthless confiscations to which he subjected the other rich shrines of the country. Subsequently, in Kalhaua's time the great quadrangular courtyard of the temple, with its lofty walls and colonnades, was used as a fortification. The destruction of the sacred image is ascribed to Sikandar Butshikast."

"Blocks measuring up to sixteen feet in length, with a width and thickness equally imposing, were no convenient materials for the builders of Muhammadan Ziarats, Hammams, etc., who have otherwise done so much to efface the remains of ancient structures in Srinagar."

"Close to the foot of the southern extremity of the hill is a rock which has from ancient times received worship as an embodiment of Ganesa... From regard for the pious king the god is said to have then turned his face from west to east so as to behold the new city. ... In fact, if we are to believe Jonariija, the rock-image has changed its position yet a second time. This Chronicler relates that Bhimasvamin from disgust at the iconoclasm of Sikandar Butshikast has finally turned his back on the city."

"‘levels between the sand ridges of the Cholistan which unmistakably represent an ancient winding bed of the Sutlej, that once joined the Hakra between Walar and Binjor’."

"A ‘popular tradition [that] recognizes the place where a ferry service is supposed to have crossed the river to Mathula on the opposite bank, a distance of more than 3 miles’—or 5 km, but of course without a drop of water between the two banks! ‘Still more striking, perhaps,’ he continued, ‘is the name of Pattan-munara, the “Minar of the ferry”, borne by an old site in Bahawalpur territory which is similarly believed to mark a ferrying place across the Hakra, the bed of which is here, if anything, still wider.’"

"On my return to India . . . a survey of any remains of ancient occupations along the dry river-bed of the Ghaggar or Hakra, which passes from the easternmost Panjab through the States of Bikaner and Bahawalpur down to Sind, seemed attractive. Traditional Indian belief recognizes in this well-marked bed the course of the sacred Sarasvatī, once carrying its abundant waters down to the ocean and since antiquity ‘lost’ in desert sands... the Ghaggar was ‘still known as the Sarsuti (the Hindi derivative of Sarasvatī) [which] passes the sacred sites of Kurukshetra near Thanesar, a place of Hindu pilgrimage’... ‘the width of its dry bed within Bikaner territory [that is, downstream of Hanumangarh]; over more than 100 miles [160 km], it is nowhere less than 2 miles [3.2 km] and in places 4 miles [6.4 km] or more’... ‘The large number of these ancient sites contrasts strikingly with the very few small villages still on the same ground.’..."

"‘The identity of the first four rivers here enumerated . . . is subject to no doubt. They correspond to the present Ganges, Jumna, Sarsuti, Sutlej . . . The order in which the first four are mentioned exactly agrees with their geographical sequence from east to west.’"

"Describing the Tirtha of Vijayeshvara, Stein gives this detail: The ancient town which once stood in the position indicated, was evidently succeeded by Vijayeshwara, the present Vijbror. The latter place situated less than two miles above Chakradhara, received its name from the ancient shrine of Shiva Vijayeshwara (Vijyesha, Vijayeshana ), the present Vijbror. This deity is worshipped to the present day at Vijbror. The site has evidently from early times been one of the most famous Tirthas of Kashmir. It is mentioned as such in the Rajaratangini and many old Kashmrian texts....The old Linga of Shiva Vijyeshwara seems to have been destroyed by Sikandar Butshikan."

"“Undergraduates, early in my classes, often think they’re smarter than the people who lived in 400 A.D.,” McCormick says. “Bit by bit, they begin to understand that those people were no more stupid or evil or smart than we are. They were very much like us.” (2011)"

"“Modern leaders, with their careful preparation and with their detailed planning, sometimes lose sight … that there are exogenous jokers, wild cards, out there that are coming out of the blue and are capable of knocking civilization off its wheels.” (2016)"

"“You and I have the extraordinary privilege of living in a time of revolutionary discovery … that extends advances of technology in the life sciences that are transforming the world today to … disciplines that are transforming our understanding of the human past, dissolving the timeworn barriers between history and prehistory, between science and the humanities.” (2014)"

"“In recent years, historians have become increasingly aware of two things. The first is the power of material evidence — including scientific evidence — beyond the written sources we’ve traditionally worked with since the 18th and 19th centuries. The second is that … exogenous factors, such as environment, also play a role in the development of human societies.” (2014)"

"[T]he author, whose work on nuclei is well known, describes a number of investigations carried out with his fog-chamber apparatus. The apparatus having been sufficiently improved, it was used for various experiments, including the growth of persistent nuclei, the production of water nuclei by evaporation, the results obtained when X-rays are allowed to strike the fog-chamber from different distances, the effect due to radium, &c. Other problems dealt with in the book are the distribution of colloidal nuclei and of ions in media other than air-water, the simultaneous variation of the nucleation and the ionization of the atmosphere of Providence, and the variations of the colloidal nucleation of dust-free air in course of time."

"In the decade between 1882 and 1892 contributions to gas thermometry and the measurement of high temperatures are few and unimportant, but work was begun in those years on both sides of the Atlantic which, for the experimental skill and persistence with which the experimental difficulties and limitations were pursued and successively overcome, surpasses any effort which has been made either before or since that time. These were the investigations of Barus at the U.S. Geological Survey in Washington and of [Ludwig] Holborn and his colleagues at the Reichsanstalt in Charlottenburg. Barus (1889) recognized as no observer who preceded him had done, the superlative importance of a uniform temperature distribution about the gas thermometer bulb for purposes of high-temperature measurement, and he took the most extraordinary precautions to maintain it. A temperature of 1000° C or more is not attained without very steep temperature gradients in the region immediately surrounding the zone of highest temperature. It is therefore a problem of great difficulty to introduce a bulb of from 10 to 20 cm. in its largest dimension into this hot zone without leaving some portion of it projecting out into a region 200° or 300° lower in temperature. Burning mixtures of gas and air for heating purposes also contributed to the irregularity and uncertainity of the temperature distribution about the bulb. Barus sought to avoid this by a method of great ingenuity, but also of great technical difficulty. He inclosed his bulb within a rapidly revolving muffle which by its motion protected every portion of the bulb from direct exposure to a particularly hot or a particularly cold portion of the adjacent furnace. This complicated furnace structure and consequently inaccessible position of the bulb made it impossible to introduce into the region about the bulb the substances whose temperature constants were to be measured and compelled him to use thermo-elements which were first calibrated by exposure in the furnace with the bulb and then used independently to measure other desired temperatures. The thermo-element has continued in general use in this intermediary rôle since that time. In the preparation and use of thermo-elements Barus also made much more extensive and elaborate studies than any one who has followed him. ...It is an unfortunate accident that history has failed to record Barus's name along with that of Le Chatelier in the development of the thermo-element for purposes of high-temperature measurement. It hardly admits of question that Barus contributed incomparably more to our knowledge of the thermo-electric properties of the different metals and their use than his distinguished French contemporary, but the 10 per cent iridium alloy which he finally selected proved to be less serviceable than the 10 per cent rhodium alloy developed by Le Chatelier... And so we find the Le Chatelier platin-rhodium thermo-element in use to-day the world over, while the magnificent pioneer work of Barus remains but little known."

"The presiding officer of this [Physics] section was Prof. Carl Barus, who fills the chair of Physics in Brown University. His inaugural address was on "Long Range Temperature and Pressure Variables in Physics." He began by giving a history of the various attempts to provide suitable apparatus for high-temperature measurement. Fusion first played an important part in the manufacture of s, and later those instruments based on specific heat showed an advantage over the fusion instruments. The was referred to as the only fruitful method of absolute pyrometry. The speaker dwelt at length on high-temperature work, the first thorough-going instance of which was by Prinsep in 1829. Then the experiments down to 1887 were considered in detail, and the conclusion reached that the data furnished by the Reichsanstalt will eventually be standard. ...Turning to the applications of pyrometry, he referred to the variation of metallic ebullition with pressure. Results already attained show an effect of pressure regularly more marked as the normal boiling point is higher. Igneous fusion was considered in its relation to pressure and with regard to the solidity of the earth, and the inference was drawn that the interior solidity of the earth, now generally admitted, is due only to superincumbent pressure, withholding fusion. The question of heat conduction was next taken up, and the results deduced by various writers as to the discussed. High pressure measurement was lengthily dealt with. Passing from this subject, the of liquids was considered. ...The paper ended with a reference to isothermals and several kindred subjects."

"A man may be a thoroughgoing soldier enough on land; but put him in the foot ropes of the flying jibboom in a storm, and he is apt to cut a most ludicrous figure. Shift a physicist's foothold of Cartesian differential coordinates, suspend him over an abyss of non-Euclidean space, and he will kick sturdily. Poor policy this, for a missionary!"

"The boon of an appropriate lemma is ideal generosity, and not even a mathematician can scorn its almost mathematical elegance."

"The reviewer is aware... he has given an imperfect account of this remarkable book. That Klein's researches constitute a splendid advance in dynamics of the rotation of a rigid body there can be no question. One cannot but hope that the outline given in these Princeton lectures may soon be expanded and put in shape more easily assimilated by persons more moderately versed in the theory of elliptic functions."

"The lecture concludes with a demonstration showing that a free body in hyperbolic non Euclidean space may be so fashioned as in real time to carry out the actual motions of the top. The form of such a body and the forces to actuate it are specified. Klein lays great stress on the beauty of this generalization. ...The full geometry of this case is not carried out in these lectures, however, and Klein regrets that the development of the s has recently fallen into abeyance."

"Mathematicians will do well to observe that a reasonable acquaintance with theoretical physics at its present stage of development, to mention only such broad subjects as electricity, elastics, hydrodynamics, etc., is as much as most of us can keep permanently assimilated. It should also be remembered that the step from the formal elegance of theory to the brute arithmetic of the special case is always humiliating, and that this labor usually falls to the lot of the physicist."

"Turning to Klein's little book, one is astonished in finding the most general aspects of the subject treated almost without computation and in so little space. ...It would have cost little to give the expanded form of the σ-function. ...Weierstrass's original notation was in terms of Abelian functions. The tremendous development of s is out of proportion with their application to natural phenomena. Meeting them rarely one forgets them. Memory peters out like the infinite series of a ζ-function."

"Among recent contributions we may refer in particular to Professor A. G. Greenhill's noteworthy papers... when one remembers that these complex curves reach only especially simple cases of motion, one may get some notion of the difficulty of the problem involved."

"In even greater measure is this true of the top. The top has been everybody's toy and must, therefore, at one time or another have piqued everybody's curiosity. Lagrange, Poinsot, Jacobi, not to mention other great names, have in turn paid their tribute; yet the top may be set spinning to-day, unhampered by a completed theory to account for its evolutions."

"Looking over such famous old books as Montmort's 'Analyse des jeux de hasard' or Moivre's 'Doctrine of Chances' one regrets that so much excellent mathematics should have been wasted on games most of which are wholly obsolete. Coriolus in his '[Théorie Mathématique des Effets du] Jeu de billard' (1835) fared better, for the game is still very much alive and its dynamical terrors unsubdued."

"I develop a method for the direct and expeditious comparison of the thermo-couple with the air thermometer. A comparison of the data... gives me a criterion of the accuracy with which the data in the region of high temperature are known. This indirect method... is not apparently as rigorous as their direct evaluation by means of the air thermometer; but the indirect method requires much smaller quantities of substance and may be conveniently extended to much higher temperatures. Taking all liabilities to error into consideration, its inferior accuracy is only apparent."

"I make... a cursory survey of certain pyro-electric properties of the alloys of . Curiously... the data... led to a striking result.. it appears that the zero resistance f(0), if the resistance at t^O be r = f(t), and the zero coefficient f^{\prime}(0)/f(0), are related to each other by a law which during the stages of low percentage alloying is independent of the ingredients of the alloy, except in so far as they modify its electrical conductivity."

"[T]he rooms which had been placed at my disposal by the American Museum of New York became temporarily unavailable. ...[W]e determined to rent a house in New Haven, Conn., and thither the laboratory was removed in November, 1882. ...[T]he city offered excellent library and other facilities for scientific work, such as can be met only in the immediate vicinity of a large university [Yale College]. ...The work in New Haven was not satisfactorily completed. In July, 1883, with the appointment of Prof. F. W. Clarke as chief chemist of the Geological Survey, our laboratory was officially connected with the chemical laboratory. Conformably with the further decision of the Director, by which the divers laboratories of the Geological Survey were united in one central laboratory in Washington, it was again necessary to change our basis of operations, this time... from New Haven to Washington. In the quarters assigned to us in the U. S. National Museum, temperature work on so large a scale... appeared impracticable, and it was therefore abandoned. ...In place of the dangerous and cumbersome apparatus of the former laboratory, the endeavor is made to reduce all apparatus to the smallest dimensions compatible with reasonable accuracy of measurement."

"[L]et me refer to my original work. Naturally, if a student has been hammering away ever since 1979... he must have accumulated a lot of litter, much of which, perhaps, should have long since been swept away. But the fates are not to be bribed either by pother or importunity. Out of 1,000 men who are called, one (probably the ratio is much smaller) is chosen to do glorious scientific work. The others? Their lot is failure. They may be equally or even more industrious, they may have equal or even greater brain power—the other 999 exist merely to make the illustrious one in whom they culminate, possible. After that, the world will say to each in words of poetic brevity: "The man has done his duty, the man can go." And they do, pretty quickly, to a gentler lethe, flowing between the banks of amaranth and asphodel. Gentlemen, I am one of the 999 about to be forgotten."

"[F]ew important steps in dynamical geology will be made until the methods for the accurate measurement of high temperatures and high pressures have not only been perfected but rendered easily available. On the basis of this conviction the present memoir on high temperatures has been prepared... [I]f the investigation be of any fullness, it is almost essential that the observer master the component parts of his research separately; and not until he has satisfactorily done this can he apply them conjointly."

"Carl Barus loved music, and composed about fifty compositions, among them a March to Pembrok Hall... and an Ode to the Steam Shovel, inspired by the daily noise outside his laboratory and was presented by him to President Faunce."

"At Brown University Carl Barus and Alpheus Packard are undoubtedly the most eminent scientists who ever occupied faculty chairs. Professor Barus was a hero-worshipper and in his home was a genius corner from which pictured faces of great scientists looked down upon him. ...The breadth of his interest and achievements was extraordinar—recall his reading of Greek tradedies in the original, his knowledge of French and Italian literatures, and the proficiency he attained in playing the violin, flute, clarinet, oboe, cornet, trumpet and trombone, in addition to the piano and organ. The brilliancy of his intellect, the modesty of his bearing, the beauty of his personality, and the kindliness of his spirit have left most precious and inspiring memories..."

"When the history of the progress of physics in the United States during the late nineteenth and early twentieth century is written, the name of Carl Barus will occupy an important place."
