-- Measuring, or what Richard Feynman called "quantitative observation" in his Lectures on Physics, is one of the defining features of science. Some scientists, most notably Steven Hawking, even believe that science is nothing but measuring – if…

The sun’s beaming rays heat the Earth, but not evenly. Many attributes of the Earth – such as its atmosphere, topography, bodies of water, and rotation – contribute to uneven heat distributions, which create air movement, or wind [].…

As President Eisenhower said, our “transportation systems are dynamic elements in the very name we bear—United States.  Without them, we would be a mere alliance of many separate parts.” (Pres. Dwight D. Eisenhower, Feb 22, 1955). The automobile became a…

The degree to which we use energy has far-reaching consequences. For example, the simple act of driving to work uses fuel that is ultimately tied to both international conflict and global climate change. The success of modern civilization is…

For many years, sunlight has been seen as a potential gold mine of useable energy for our global needs.  Having successfully used the sun to grow food to feed the world, people are now trying to harvest the sun’s energy and convert it into electric…

Fossil fuels are running out Since the mid nineteenth century, humans have progressively mastered the discovery, extraction, and combustion of fossil fuels. Fossil fuels are the remains of organisms, mostly thick growths of plants from more than 500…

Last year, the world invested more money in renewable energy than ever before, at over $257 billion [1]. There is no question that renewable energy projects need finance to develop and commercialize. According to the International Energy Agency (IEA),…

-- The world is excited about solar cells – and with good reason. Imagine the City of the Future, where every exposed surface has solar cells on it, converting the sun’s energy into electricity. This vision could include solar cells on windows, on top of…

-- The idea that we could grow fuel from a renewable resource is incredibly exciting. Researchers have been hard at work developing biofuels that will allow us to run our society using easily renewable resources. These efforts have gained a lot of media…

If you’ve watched the movie The Day after Tomorrow, you must remember the climate-related natural disasters that ravaged the human civilization. Though the events depicted in the movie are unrealistic, we are still dramatically altering Earth’s…
