These DIY Eco-Friendly "Air Conditioners" Are Cooling Down Bangladesh Out in the sticks of Bangladesh, the threat of flooding means that 70 percent of the population live in corrugated tin huts, most of which aren’t hooked up to an electricity supply. In the heat of the summer, this can practically turn these houses into ovens. However, a project called Eco-Cooler is spreading knowledge of a cheap and electricity-free method to cool down houses throughout Bangladesh. The beauty of the project is it needs little more than a few plastic bottles and a board. It was started through a collaboration between advertising agency Grey Dhaka and Grameen Intel Social Business Ltd. Here’s how it works: Plastic bottles are cut in half and then mounted into a grid through bottleneck-sized holes.
Philosophy Philosophy is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. The Ancient Greek word philosophia was probably coined by Pythagoras and literally means "love of wisdom". In the 19th century, philosophy became more professionalized as it began to be studied and taught in modern research universities. Contemporary academic philosophers subdivide research areas in various ways. For example, topical divisions include major branches such as epistemology, logic, metaphysics, ethics, aesthetics, and other specialized branches. Other ways of dividing include historical period (e.g., ancient and modern); thinker (e.g., Platonism, Confucianism, Kantianism); or philosophical tradition (e.g., analytic or Continental). Many of these recurring questions are still debated in philosophy and other fields today.

How to Kill Your Child's Creativity - Playful Learning Kids are born creative geniuses. But unfortunately, by the time they reach the third or fourth grade, their creativity has sunk.

Elusive acid finally created After more than a century of searching, chemists have finally nabbed a legendary acid. The acid called cyanoform or tricyanomethane appears widely in textbooks as one of the strongest carbon-based acids known. Yet despite attempts to make the acid dating back to 1896, cyanoform has evaded chemists until now. Researchers report September 18 in Angewandte Chemie International Edition that they isolated the acid by figuring out crucial experimental conditions.
