This covers the implementation of database clustering through Open Source technologies. It is designed to teach the students on how to get, install and configure the required software and eventually set-up the cluster. It also provides an example on how a web application connects randomly to any database server in the cluster and still gets the same data. Through this example, high data availability solution is clearly demonstrated in the sense that if and when one database server in the cluster is down, the other database server can continue providing the needed data.

This experimental one-week course is a freshman-accessible hands-on introduction to Nuclear Science and Engineering at MIT. Students build and test their own Geiger Counter, and so doing, they explore different types and sources of radiation, how to detect them, how to shield them, how to accurately count / measure their activity, and explore cryptographical applications of radiation. This course is meant to be enjoyable and rigorous at the same time. This course was offered during the Independent Activities Period (IAP), which is a special 4-week term at MIT that runs during January each year. WARNING NOTICE: An activity described in this course is potentially hazardous and requires a high level of safety training, special facilities and equipment, and supervision by appropriate individuals. You bear the sole responsibility, liability, and risk for the implementation of such safety procedures and measures.

This fluent and comprehensive field guide responds to increased interest, across the humanities, in the ways in which digital technologies can disrupt and open up new research and pedagogical avenues. It is designed to help scholars and students engage with their subjects using an audio-visual grammar, and to allow readers to efficiently gain the technical and theoretical skills necessary to create and disseminate their own trans-media projects.

A collection of repeat photography of glaciers from the National Snow and Ice Data Center (NSIDC). The photos are taken years apart at or near the same location, and at the same time of year. These images illustrate how dramatically glacier positions can change even over a relatively short period in geological time: 60 to 100 years. Background essay and discussion questions are included.

This video provides a good introduction to the field of attribution science. Beginning with an introduction to weather and climate, it describes how severe weather might be linked to climate change and the science behind attribution studies. It gives a good explanation behind how scientists use climate models to study whether severe weather events were influenced by climate change. It also discusses the question, "does climate change cause extreme weather?" and provides an introduction to the concepts of probability, causation, and correlation in regards to attribution science (how much climate change influenced an event verses normal variations in weather).

Students gain an understanding of the factors that affect wind turbine operation. Following the steps of the engineering design process, engineering teams use simple materials (cardboard and wooden dowels) to build and test their own turbine blade prototypes with the objective of maximizing electrical power output for a hypothetical situation—helping scientists power their electrical devices while doing research on a remote island. Teams explore how blade size, shape, weight and rotation interact to achieve maximal performance, and relate the power generated to energy consumed on a scale that is relevant to them in daily life. A PowerPoint® presentation, worksheet and post-activity test are provided.

The purpose of this hands-on activity is to demonstrate that air has weight and how this fact can be concretely illustrated. Eventually and through more experience gained by conducting mind-engaging activities, the learner will come to a basic understanding that a given volume of air at higher elevations is less dense and has fewer molecules per volume than a similar volume at lower elevations.

Energy access plays a vital role in reducing undernourishment and improving food security. It boosts agricultural productivity, enhances food quality, reduces losses, and enables transportation. However, addressing factors like political instability and poor policies is crucial alongside increasing energy use.

Energy use influences life expectancy. Access to energy services improves well-being and extends lifespan, while deprivation has the opposite effect. Modest energy increases positively impact longevity, especially in low-energy regions. However, beyond a certain point, additional energy use has diminishing returns for life expectancy.

The Human Development Index (HDI) measures overall well-being beyond economic growth, focusing on health, education, and income. Countries with low development levels use less energy, and small energy increases lead to significant HDI improvements. Energy efficiency improvements can be made without compromising quality of life, addressing environmental concerns and promoting equity.

hile higher incomes generally lead to greater life satisfaction, it's not a guarantee. People in countries with high life satisfaction tend to use more energy, which can enhance comfort and mobility. Modest increases in energy use can significantly improve life satisfaction, but there are diminishing returns at higher levels.

While moving up the income ladder is generally accompanied by increased energy use, there are significant variations within income groups. Factors such as the economy's structure, geography, climate, lifestyle, public policy, and consumer attitudes also influence how effectively energy use translates into income.
Population growth does impact energy use, but per capita energy consumption varies …
Population growth does impact energy use, but per capita energy consumption varies greatly across countries due to factors like geography, climate, economic structure, policies, and cultural preferences. Countries with small populations can have high energy consumption, while countries with large populations may use less energy.

Students' understanding of how robotic ultrasonic sensors work is reinforced in a design challenge involving LEGO MINDSTORMS(TM) NXT robots and ultrasonic sensors. Student groups program their robots to move freely without bumping into obstacles (toy LEGO people). They practice and learn programming skills and logic design in parallel. They see how robots take input from ultrasonic sensors and use it to make decisions to move, resulting in behavior similar to the human sense of sight but through the use of sound sensors, more like echolocation. Students design-test-redesign-retest to achieve successful programs. A PowerPoint® presentation and pre/post quizzes are provided.
