Dec 27, 2010 When you have major changes going on in your life, or you’re just frustrated about where you are, it’s easy to get trapped in a cycle of depression, bad moods and frustration. I know, I’ve been there … and when I’m not careful, I still get there more than I want to.
Climate Progress recently reported on a study that found both economic and environmental benefits if homes in the northeastern United States upgraded older heating systems by moving from heating oil to switchgrass. However, one point to emphasize was the findings were specific to those circumstances — the region, the homes, and that particular use. Switchgrass was not nearly as good an idea for electricity generation or transportation fuel.

No matter how much you know, there is always something new to learn about science. While your college courses may cover the basics, you can get a more in-depth look at a wide variety of topics from Internet resources such as these great documentaries. These selections will help you explore everything from the inner reaches of the human mind to the outer areas of our universe and just about everything else in between.
The term ‘geek’, once used to label a circus freak, has morphed in meaning over the years. What was once an unusual profession transferred into a word indicating social awkwardness. As time has gone on, the word has yet again morphed to indicate a new type of individual: someone who is obsessive over one (or more) particular subjects, whether it be science, photography, electronics, computers, media, or any other field.
Hi, I'm Mitch Fincher and these pages are from a talk I gave while a Civil Engineering student at Texas Tech University. The following is the basic pattern for building cantilevered structures with Pennies. Although it looks trivial, we can build amazing structures with these pillars. All penny columns are ten high, a "stack". Two side-by-side pennies held in place by a penny above them is called a "triad".
The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below. Remarkably, this minimum energy doesn’t just apply to particles, but to any vacuum, whose energy is called “vacuum energy.”
