10 Strange Islands" How Earthquakes Work" How Global Warming Works" Global warming was once an uncommon term used by a few scientists who were growing concerned over the effects of decades of pollution on long-term weather patterns.

Today, the idea of global warming is well known, if not well understood. It is not unusual to hear someone complaining about a hot day or a freak storm and remark, "It's global warming. " Well, is it? In this article, we'll learn what global warming is, what causes it, what its current effects are and what the future effects could be. Although there has been a scientific consensus on global warming, some aren't sure it's something we need to worry about. How Math Works" It's easy to think of mathematics as a kind of storybook sorcery -- a powerful secret language known to few, mastered by inhuman agents (such as your calculator) and underpinning the very fabric of the universe.

Even if we avoid such hyperbole, the fact remains: Many of us are mathematically illiterate in a world that runs on math. When was the last time you seriously crunched some numbers with only pen and paper? In his book "The Geometry of Paradise," Mark A. Peterson described the people of medieval Europe as a nonmathematical culture in possession of sophisticated mathematics. Mathematicians of the day certainly honed their skills but mostly out of love for mathematical abstractions. Today, the mathematics field is far more vibrant than it was in the Middle Ages, but it still eludes an alarming number of those who depend on it.

The ramifications of mathematical illiteracy are very real. So let's demystify the world of mathematics. 5 Reasons Not to Buy a Hybrid" Speaking of driving style, a person's daily commute should also be a major contributing factor when buying a hybrid.

As you can see from the fuel economy numbers on the previous page, some hybrids get better mileage around town than they do on the highway. That's because at lower speeds, usually up to about 40 miles per hour (64.4 kilometers per hour), full hybrid cars can run using only their electric motor -- no gasoline is used at all. And, while stopped at red lights or in horrendous city traffic, the engine can cut off completely, and then start up again when the vehicle needs the extra boost. This is often referred to as idle-stop technology or start-stop technology. If in-town, low-speed, start-stop driving is a major part of your day, a hybrid will probably get the better side of the gas mileage equation. How Money Laundering Works" ­In October 2005, U.S. congressman Tom DeLay was indicted on money laundering charges, forcing him to step down as House Majority Leader.

Money laundering is a serious charge -- in 2001, U.S. prosecutors obtained almost 900 money-laundering convictions with an average prison sentence of six years. The rise of global financial markets makes money laundering easier than ever -- countries with bank-secrecy laws are directly connected to countries with bank-reporting laws, making it possible to anonymously deposit "dirty" money in ­one country and then have it transferred to any other country for use. ­ ­ Money lau­ndering happens in almost every country in the world, and a single scheme typically involves transferring money through several countries in order to obscure its origins. In this article, we'll learn exactly what money laundering is and why it's necessary, who launders money and how they do it and what steps the authorities are taking to try to foil money-laundering operations. What should you not buy in bulk?" It's a money-saving proposition that is hard to pass up: buying groceries and other staples in bulk so that you pay less for those items in the long run.

And it's true that you can rack up some serious savings through shopping for bulk items at warehouse club stores, or stocking up when items go on sale at regular retail destinations. Warehouse clubs like Costco maintain profit margins of about 8 to 14 percent, as opposed to the 20 to 40 percent margins of traditional grocery chains [source: Warehouse Club Focus]. But there are some good rules of thumb to keep in mind when bulk shopping, to make sure that you don't end up wasting money, instead of saving it. Be mindful of storage concerns. That killer deal you just got on a case of toilet paper may not seem so convenient when you can't find room for it in your closet.If you spend money on something you don't normally use, or don't really need, you're not saving money by buying it in bulk.
