Helmet for My Pillow: From Parris Island to the Pacific by Robert Leckie
Unrestricted Use
Public Domain
Rating
0.0 stars

Editorial Reviews The New York Times, September, 1957.

“...This is an old story, but it is told in a fresh and lovely voice. Robert Leckie writes with charm, with personal humility, with humor, with a rare gift for capturing all that is human in the most inhuman of man's activities. He makes no bones about it— the war is what happened to him. The point of view is not the grand strategy of victory, but the immediate tactic of personal survival. By turns a boot, a machine gunner on Guadalcanal, a liberty hound in Australia, an intelligence scout on Peleliu — briefly a self-styled "brig rat" subsisting on bread and water and finally a casualty —Private Leckie fought the enlisted man's battle.

By David Dempsey The Marine Corps Association and Foundation Revisiting a Pacific War Classic by Lt. Col. Michael Grice Robert

Leckie’s "Helmet for My Pillow" has been my single favorite military book for over 30 years. Written from the perspective of a young participant in the great endeavor that was World War II, it is a soulful, wrenching, humorous, and insightful account of one youth’s journey into manhood via the Pacific campaigns spearheaded by the 1st Marine Division. I first read it as a junior high school student in 1980, and I have reread it nearly every year since. It has framed my perspectives of the Marine Corps, of leadership, of enlisted service, of officers, and of combat as I have aged, matured, and risen through the ranks. Leckie doesn’t provide a technical, historical account consisting of units, maps, and strategy, but instead provides a humanistic view of the Marine Corps at war from the perspective of an often-bewildered observer caught up in the whirlwind of events. Beginning with his rush to service after the attack on Pearl Harbor,

Leckie brings the reader along as a fellow traveler on his journey to war. He presents his story through a framework of symbolism, simile, and metaphor; almost no character is identified by actual name but instead by title or attribute that the author chooses to best typify them. Generally warm to his peers (to whom have been bestowed titles such as “Hoosier,” “Chuckler,” and “Runner,” all so called because of their origins, habits, or claims to fame), he is critical of his seniors, most notably his officers. “Commando,” for example, was what we would consider an exceptionally motivated officer in the modern sense, but his Marines viewed him with suspicion and occasional terror as he attempted to utilize urban combat techniques in the dank jungles of the Pacific. “Commando sits on his brains,” says Leckie and his mates; they recognize that he is incredibly brave, but such bravery is not the only quality that a leader needs to possess in order to inspire men.

He writes of officers who only venture into the lines when they hear that Leckie has somehow obtained a box of cigars; true to his status as a carefree private he ensures that they receive none. Leckie is not uncomplimentary to all of his leaders, however, as he admiringly terms one of his lieutenants “Spearmint” because he has the lowly affectation for chewing gum. Spearmint they follow out of respect and admiration; Commando they follow because they are Marines, and Marines follow orders. The juxtaposition of leadership types and styles from the perspective of an articulate young private is an object lesson that all Marine leaders should heed, and there is no finer case study than Helmet for My Pillow.

The book should not be read only for the study in leadership, but also from the perspective of a Marine engaged in a seemingly endless conflict. Leckie speaks of timeless war where rumors of returning home rise and fall with the completion of each assault. He chronicles the chaotic creation of a newly formed division as it prepares to fight; the murderous landings and campaigns in Guadalcanal, New Britain, and Peleliu; and the adventures and misadventures of liberty in Australia....

History and Cultural Memory in Neo-Victorian Fiction
Only Sharing Permitted
CC BY-NC-ND
Rating
0.0 stars

History and Cultural Memory in Neo-Victorian Fiction combines innovative literary and historiographical analysis to investigate the way neo-Victorian novels conceptualise our relationship to the Victorian past, and to analyse their role in the production and communication of historical knowledge. Positioning neo-Victorian novels as dynamic participants in the contemporary historical imaginary, it explores their use of the Victorians' own vocabularies of history, memory and loss to re-member the nineteenth century today. While her focus is neo-Victorian fiction, Mitchell positions these novels in relation to debates about historical fiction's contribution to historical knowledge since the eighteenth century. Her use of memory discourse as a framework for understanding the ways in which they do lay claim to historical recollection, one which opens up a range of questions beyond historical fidelity on the one hand, and the problematics of representation on the other, suggests new ways of thinking about contemporary historical fiction and its prevalence, popular appeal, and nmnenonic function today.

Rating
0.0 stars

Students see that geometric shapes can be found in all sorts of structures as they explore the history of the Roman Empire with a focus on how engineers 2000 years ago laid the groundwork for many structures seen today. Through a short online video, brief lecture material and their own online research directed by worksheet questions, students discover how the Romans invented a structure known today as the Roman arch that enabled them to build architecture never before seen by humankind, including the amazing aqueducts. Students calculate the slope and its total drop and angle over its entire distance for an example aqueduct. Completing this lesson prepares students for the associated activity in which teams build and test model aqueducts that meet specific constraints. This lesson serves as an introduction to many other geometry—and engineering-related lessons—including statics and trusses, scale modeling, and trigonometry.

This is one component of the Source to Sink Mini Lesson Set
This module is part of a larger set of mini-lessons that explores the variations in water and particulate mass flux from rivers that result from changing climate patterns and human activity in the Holocene. Long-period variations in runoff will be explored in this module on the Holocene Climatic Optimum, when intensification of the Southwest monsoon affected massively increased river discharge in South Asia. The exercise will detail the operation of the Asian monsoon and interpret stratigraphic evidence for increased sediment discharge during the Holocene Climatic Optimum using the Ganges-Brahmaputra as an example.

Students apply the concepts of conduction, convection and radiation as they work in teams to solve two challenges. One problem requires that they maintain the warm temperature of one soda can filled with water at approximately human body temperature, and the other problem is to cause an identical soda can of warm water to cool as much as possible during the same 30-minute time period. Students design their engineering solutions using only common everyday materials, and test their devices by recording the water temperatures in their two soda cans every five minutes.

Students explore material properties by applying some basic principles of heat transfer. They use calorimeters to determine the specific heat of three substances: aluminum, copper and another of their choice. Each substance is cooled in a freezer and then placed in the calorimeter. The temperature change of the water and the substance are used in heat transfer equations to determine the specific heat of each substance. The students compare their calculated values with tabulated data.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Salmon are famous for their swims upriver to spawn. Many people focus on this amazing feat of stamina, but even more remarkable is their ability to switch from living in freshwater to seawater, and back again. Most fish make their homes in just one type of water. So how do salmon do it? A team of biologists at Skidmore College, the U.S. Geological Survey, and the University of Gothenburg recently uncovered changes in the expression of certain genes that explain in part how Atlantic salmon make the transition. Atlantic salmon are born in freshwater, and between the ages of one and four migrate downstream to the sea. Before starting this migration, the fish undergo a months-long process preparing them for life in seawater. This is called smoltification. During this time, fish develop gill cells called ionocytes that contain specialized proteins that pump out excess salt..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.
