Environmental activism of Al Gore Childhood[edit] Gore stated in an interview for The New York Times that his interest in environmentalism began when he was a teenager: As I was entering high school, my mother was reading Silent Spring and the dinner table conversation was about pesticides and the environment ... The year I graduated from college the momentum was building for Earth Day. Intuitor, How to Use Movie Physics in the Classroom How to Use Movie Physicsin the Classroom The Good, the Bad, and the Ugly Movie physics can provide a bonanza of enrichment activities for both high school physics students and first year physics students in college. These generally require nothing more than a VCR and stopwatch. Some movie scenes provide examples of good physics and others bad physics but all can be analyzed and used as topics of discussion. When the physics are so bad they're downright ugly, the real fun begins.

Environment Environment may refer to: It may also refer to: Built environment, constructed surroundings that provide the setting for human activity, ranging from the large-scale civic surroundings to the personal placesKnowledge environment, social practices, technological and physical arrangements intended to facilitate collaborative knowledge building, decision making, inference or discoveryNatural environment, all living and non-living thingsSocial environment, the culture that an individual lives in, and the people and institutions with whom they interactPhysical environment, in ecology Division of Building Science and Technology - City University of Hong Kong Building simulation software can be used to predict the energy consumptions in buildings and to perform dynamic thermal analysis of HVAC systems. An accurate estimation requires the precise representation of the periodic change in local weather conditions. Typical weather year files like Test Reference Year (TRY) and Typical Meteorological Year (TMY) are commonly used for such purposes. Very often the weather year file developed for one place is employed in the numerical simulation of the other places having geographical similarities. Taking the fact that there are long-term changes in average weather conditions in the South China region, the practices of developing typical weather year files were reviewed and discussed based on two neighboring cities: Hong Kong and Macau. Through the statistical analysis of the 25-year weather data (1979-2003) of Hong Kong, the TMY file for Hong Kong was produced.

National geographic Geography is the study of places and the relationships between people and their environments. Geographers explore both the physical properties of Earth’s surface and the human societies spread across it. They also examine how human culture interacts with the natural environment, and the way that locations and places can have an impact on people. Geography seeks to understand where things are found, why they are there, and how they develop and change over time. Environmental Integrity Environmental Protections on the Chopping Block The Trump Administration is rolling back a wide variety of regulations that protect our water, air, land, and public health in order to benefit high-pollution industries that donate heavily to political campaigns. Although the numbers show that environmental regulations on the whole are good for the economy and have benefits that far exceed costs by preventing illness and death from dangerous pollution, Trump’s war on environmental protections has been relentless. The administration has targeted almost 80 environmental rules, including those meant to control greenhouse gases, coal ash waste, water pollution, mercury, and smog.

Environmental Issues Author and Page information by Anup ShahThis Page Last Updated Monday, February 02, 2015 This part of the global issues web site attempts to highlight some of the environmental issues and concerns that have an affect on all of us — from what we do, to what we don’t do. Typical meteorological year A typical meteorological year (TMY) is a collation of selected weather data for a specific location, generated from a data bank much longer than a year in duration. It is specially selected so that it presents the range of weather phenomena for the location in question, while still giving annual averages that are consistent with the long-term averages for the location in question. TMY data is frequently used in building simulation, in order to assess the expected heating and cooling costs for the design of the building.
