Searching for modifications to the exponential radioactive decay law with the Cassini spacecraft

Data from the power output of the radioisotope thermoelectric generators aboard the Cassini spacecraft are used to test the conjecture that small deviations observed in terrestrial measurements of the exponential radioactive decay law are correlated with the Earth-Sun distance. No significant deviations from exponential decay are observed over a range of 0.7 - 1.6 A.U. A 90% Cl upper limit of 0.84 x 10^-4 is set on a term in the decay rate of Pu-238 proportional to 1/R^2 and 0.99 x 10^-4 for a term proportional to 1/R.Comment: 3 pages, 3 figures, Late

The High Water Mark of Social History in Civil War Studies

Just hours before the Army of Northern Virginia raised the white flag at Appomattox Court House, Confederate Colonel Edward Porter Alexander approached his commanding officer, Robert E. Lee, with what he hoped was a game-saving plan. Rather than suffer the mortification of surrendering, Alexander begged Lee to scatter his men across the countryside like “rabbits & partridges” where they could continue waging war, not as regular Confederate soldiers, but as elusive guerrilla fighters. Lee listened patiently to his subordinate’s reasoning for irregular warfare. Before Alexander finished, he reminded Lee that the men were utterly devoted to their commanding general, and that such loyalty would continue to inspire the sacrifice of more blood, even if it meant taking to the woods and fighting like common outlaws. When Alexander concluded his impassioned plea, Lee asked his subordinate to imagine what would happen if he turned Alexander’s suggestion into official policy. But before Alexander had a chance to respond, Lee reminded him that virtually every Southern community had been overrun by Union armies, that farms were in disarray, and that crops were ruined. Lee feared that his veterans, upon returning home, would have no choice but to plunder and rob for survival. It would take no time for his disciplined army to descend into a demoralized mob that would take the rest of the South into a downward spiral of unending and unrestrained violence. “As for myself,” Lee concluded, “while you young men might afford to go to bushwhacking, the only proper & dignified course for me would be to surrender myself & take the consequences of my actions.” [excerpt

Science and the Knowledge of God: From Machine to Metaphor

After a review of how the machine model of nature has been used to argue both for and against the existence of God, the author makes the case that metaphors borrowed from the sciences can suggest new information about God

The Trophies of Victory and the Relics of Defeat: Returning Home in the Spring of 1865

The remains of a lone apple tree, cut down and carved into small pieces by Confederate soldiers, lay along a rutted dirt road that led to the village of Appomattox Court House. Earlier on 9 April 1865, Robert E. Lee had waited under the shade of the apple tree, anxious to hear from Ulysses S.Grant about surrendering his army. Messages between the generals eventually led to a brief meeting between Lee and two Union staff offices who then secured the parlor in Wilmer McLean\u27s house, where Grant dictated the surrender terms to Lee. As soon as the agreement was signed and Lee walked out the door, Union officers decluttered the parlor with Yankee efficiency, cutting strips of upholstery from plush sofas, breaking chair legs into small keepsakes, and appropriating candleholders and chairs until the room was left barren.

Is There a Southern Doctor in the House?

Doctoring the South does not go down easily, but a patient reader will benefit immeasurably from this brilliantly conceived and thoroughly researched book. Stephen Stowe has penetrated the scientific and cultural world of southern physicians during the mid-nineteenth century, showing how white doctors made meaning of their lives as they struggled to gain mastery of the sickly bodies of others. The confrontation between patient and physician, between sickness and health, reveals what Stowe calls the country orthodoxy style of southern practitioners. Country orthodoxy inextricably tied a doctor’s understanding of what it meant to be a professional to his local community. It was within a specific locale that the day-to-day reality of practicing medicine gave shape and meaning to the art of healing. [excerpt

Trademark Vigilance in the Twenty-First Century: An Update

The trademark laws impose a duty upon brand owners to be vigilant in policing their marks, lest they be subject to the defense of laches, a reduced scope of protection, or even death by genericide. Before the millennium, it was relatively manageable for brand owners to police the retail marketplace for infringements and counterfeits. The Internet changed everything. In ways unforeseen, the Internet has unleashed a tremendously damaging cataclysm upon brands—online counterfeiting. It has created a virtual pipeline directly from factories in China to the American consumer shopping from home or work. The very online platforms that make Internet shopping so convenient, and that have enabled brands to expand their sales, have exposed buyers to unwittingly purchasing fake goods which can jeopardize their health and safety as well as brand reputation. This Article updates a 1999 panel discussion titled Trademark Vigilance in the Twenty-First Century, held at Fordham Law School, and explains all the ways in which vigilance has changed since the Internet has become an inescapable feature of everyday life. It provides trademark owners with a road map for monitoring brand abuse online and solutions for taking action against infringers, counterfeiters and others who threaten to undermine brand value

The War for the Common Soldier: How Men Thought, Fought, and Survived in Civil War Armies

How did Civil War soldiers endure the brutal and unpredictable existence of army life during the conflict? This question is at the heart of Peter S. Carmichael\u27s sweeping new study of men at war. Based on close examination of the letters and records left behind by individual soldiers from both the North and the South, Carmichael explores the totality of the Civil War experience--the marching, the fighting, the boredom, the idealism, the exhaustion, the punishments, and the frustrations of being away from families who often faced their own dire circumstances. Carmichael focuses not on what soldiers thought but rather how they thought. In doing so, he reveals how, to the shock of most men, well-established notions of duty or disobedience, morality or immorality, loyalty or disloyalty, and bravery or cowardice were blurred by war. Digging deeply into his soldiers\u27 writing, Carmichael resists the idea that there was a common soldier but looks into their own words to find common threads in soldiers\u27 experiences and ways of understanding what was happening around them. In the end, he argues that a pragmatic philosophy of soldiering emerged, guiding members of the rank and file as they struggled to live with the contradictory elements of their violent and volatile world. Soldiering in the Civil War, as Carmichael argues, was never a state of being but a process of becoming.https://cupola.gettysburg.edu/books/1146/thumbnail.jp
