For the first time, the ' Technograph" is being sent to the high schools of Illinois through the cooperation of the staff and the College of Engi- neering. We are doing this in an effort to bring future Illini a glimpse of their Universit>-. Many of >ou in the reading audience will soon finish your high school training and will enroll in this and other universities. We hope that through the "Technograph" we ma> furnish >ou with a better in- sight of what waits in store for \ou. As an introduction to new readers, we would like to explain that the '"Technograph" is a monthly magazine written and managed b> the stu- dents of the College of Engineering of the University of Illinois. We try to bring to our readers some knowledge of the courses offered here, the progress in research at the University, and many other educational aspects of college life. We also try to introduce you to leading members of the student body and faculty, the leading engineers of today, and the leading engineers of tomorrow. We report news of the various engineering soci- eties and honoraries that are active here on campus, and endeavor to familiarize you future Illini with what lies in store for you at the University. We believe that we are attending one of the finest engineering schools in the country, and the staff of the "Technograph" will make every effort in issues to come to substantiate that claim. We invite your interest and questions, and will be glad to furnish you with any information about the University and the College of Engineering that you desire. We are looking forward to a long friendship and association. THE EDITOR.

  • A Reconstruction of the Differential Analyzer in Meccano

    A Reconstruction of the Differential Analyzer in Meccano

    FEATURE A Reconstruction of the Differential Analyzer in Meccano The challenges of torque amplifiers, integrators, and backlash By Tim Robinson was first introduced to Meccano, a child’s educational construction set cre- ated in the United Kingdom, at about the age of six and quickly became fascinated with it as a medium for constructing working mechanisms and small machines. Over the next ten years or so, I gath- Iered quite a large collection. I first attempted to construct a differential analyzer in Meccano around 1971. I had just encountered calculus in high school and at the same time I started to develop an interest in computers. One of the first books I read on computers included a chapter on analog computation, and on the differential analyz- er in particular. Significantly, the book briefly men- ©DIGITALVISION tioned that simple differential analyzers had been constructed in Meccano in the 1930s. So began an inter- est that has remained with me for more than 30 years. Early Attempts My early attempts were not very successful because of the diffi- culty of constructing functioning torque amplifiers. When Hartree and Porter built the first Meccano differential analyzer at Manchester Universi- ty, their goal was to build a working machine quickly. They used Meccano simply because it was readily available and allowed them to avoid designing and custom machining most of the required parts. However, Hartree and Porter felt no constraint to stay within the limits of the Meccano system. In particular, they did not believe that adequate torque amplifiers could be made without custom machining.

    In the Nature of Cities: Urban Political Ecology

    In the Nature of Cities In the Nature of Cities engages with the long overdue task of re-inserting questions of nature and ecology into the urban debate. This path-breaking collection charts the terrain of urban political ecology, and untangles the economic, political, social and ecological processes that form contemporary urban landscapes. Written by key political ecology scholars, the essays in this book attest that the re- entry of the ecological agenda into urban theory is vital, both in terms of understanding contemporary urbanization processes, and of engaging in a meaningful environmental politics. The question of whose nature is, or becomes, urbanized, and the uneven power relations through which this socio-metabolic transformation takes place, are the central themes debated in this book. Foregrounding the socio-ecological activism that contests the dominant forms of urbanizing nature, the contributors endeavour to open up a research agenda and a political platform that sets pointers for democratizing the politics through which nature becomes urbanized and contemporary cities are produced as both enabling and disempowering dwelling spaces for humans and non-humans alike.

    Our Ocean Backyard –– Santa Cruz Sentinel columns by Gary Griggs, Director, Institute of Marine Sciences, UC Santa Cruz. #73 January 29, 2011 Ships of cement The SantaCruzCement taking on a load of dry cement at the former wharf below the cliffs in Davenport opposite the cement plan. Santa Cruz County is probably one of the only places around that has had three large “cement” ships in its coastal history, none of which was made solely of cement. All of the ships dated from the early part of the last century, and each used for very different purposes. One of the natural resources of the Santa Cruz Mountains’ that was exploited early on was limestone, actually marble, a basic raw material for making cement. When the Davenport cement plant was being constructed in 1905, there wasn’t yet a railroad up the north coast, but it wasn’t long until trestles were built across the canyons and tracks were laid. A direct rail connection up the coast to San Francisco was never completed, so cement had to be transported through a longer and more indirect route, south past Watsonville, through Chittenden Pass, and then north to the bay area. An idea was hatched, which seemed like a great solution at the time; transport the cement by ship directly to Stockton where it was to be offloaded. So as only engineers can, a pier was boldly designed and constructed in the early 1930s starting from the sea cliff opposite the cement plant. A pile driver was lowered down the cliff and steel piles were driven into the seafloor.
