While the American system of politics has generally been defined as a two-party system, occasionally a third party emerges, influencing elections and siphoning important votes from the major parties. Third parties often begin as single-issue parties that oppose or promote a certain social, economic, or political topic. For example, the Republican Party formed in the 1850’s as a third party in opposition to slavery. Similarly, in 2000, Ralph Nader formed the Green Party that focused on environm
16.A47 The Engineer of 2020 (MIT)
Numerous recent studies have shown that the U.S. has relatively low percentages of students who enter science and engineering and a high drop-out rate. Some other countries are producing many more scientists and engineers per capita than the U.S. What does this mean for the future of the U.S. and the global economy? In this readings and discussion-based seminar you will meet weekly with the Dean of Undergraduate Education to explore the kind of education MIT and other institutions are and should
This interactive activity adapted from Indiana University features time-lapse videos that reveal the movement and growth of plants in their pursuit of light. Although plants have no choice about where they are rooted, they do respond to environmental cues in ways that enable them to survive. This interactive site includes five videos using time lapsed photography (no audio) with written explanations. The videos include: seed germination and gravity, light and dark responses, twining vines, pl
Agent Based Modeling of Complex Adaptive Systems (basics)
Our human society consists of many intertwined Large Scale Socio-Technical Systems (LSSTS), such as infrastructures, industrial networks, the financial systems etc. Environmental pressures created by these systems on Earth’s carrying capacity are leading to exhaustion of natural resources, loss of habitats and biodiversity, and are causing a resource and climate crisis. To avoid this sustainability crisis, we urgently need to transform our production and consumption patterns. Given that we, as
