There are a lot of different kinds of music. Some of the most popular kinds of music today are rock, techno, hip-hop, and rap. All of those kinds of music affect you in different ways. Other kinds of music are instrumental music, opera, etc. Those kinds of music also affect you. The music that affects you the most is calm music like instrumental or fast music like rock or techno. Rock and techno make you speed up, and instrumental or calm music makes you slow down and feel more calm.

Music can also slow down and equalize brain waves. A brain has 4 kinds of waves. It has beta waves, alpha waves, theta waves, and delta waves. When we do daily activities and experience emotions that’s when we use beta waves. Calmness is when we use alpha waves ,when your sleeping you use theta waves , and lastly when you are in deep sleep or in meditation that is when delta waves are used. When your brain waves are slow that is when you are very calm. Different types of music cause different waves. If you listen to calm music then the waves will drop to delta and theta. If you listen to fast or loud music your brain waves will most likely be alpha or beta.

n experiments, the cream-based ultra-violet (UV) filters -- used to protect skin from the harmful effects of sun exposure -- caused bleaching of coral reefs even in small quantities, the study found.

But some 60 percent of these reef systems are threatened by a deadly combination of climate change, industrial pollution and excess UV radiation.

The new study, published in U.S. journal Environmental Health Perspectives, has now added sun screens to the list of damaging agents, and estimates that up to 10 percent of the world's reefs are at risk of sunscreen-induced coral bleaching.

This is like taking 6.3 million cars off the road!

Small gaps in your windows and doors can cause you to consume a lot more energy than you really need to in order to heat and cool your home.

Pollution at the nation’s 3,500 ocean, lake and bay beaches resulted in more than 25,000 closing or swimming advisory days last year, 28 percent more than in 2005, and the highest number in the 17 years that records have been kept, according to a new federal report released Tuesday.

he prime culprit was storm water runoff

Another 1,300 days were attributed to sewage spills and overflows.

largest and most productive estuaries in North America.  

However, in 1993 the EVOS Trustee Council funded an additional survey that estimated 7 km of shoreline were still contaminated with subsurface oil.

Because a significant survey of Prince William Sound had not been conducted since 1993 and the cumulative extent of the remaining oil was unknown, concerns were generated by the public and scientific communities about the oil’s possible continuing effects on humans and fauna potentially exposed to the oil directly or indirectly.

According to the American College Dictionary, pollution is defined as:  �to make foul or unclean; dirty.

When it is unfit for its intended use, water is considered polluted.

Point sources of pollution occur when harmful substances are emitted directly into a body of water.

Looks like a pillar of iTunes content might be on the brink of collapse -- Universal Music, the world's largest music business, has officially opted not to renew its contract with Apple for vending music on the iTunes Music Store. We don't know specifically what caused Universal to turn away -- perhaps it's the weight of the rising anti-DRM movement among consumers, or perhaps it's because of Stevie J.'s brash negotiating tactics, continual refusal to hand over iPod cash, or oceanic persistence in keeping tracks locked in at $0.99. Whatever the reason, we can't say we're all that surprised; Universal's been a pain in Apple's ass for years now. So what's the end result? Well, Universal music will still be sold through iTunes at will, so that means consumers can keep buying tracks for the time being, but Apple runs the risk of losing Universal's content on very short notice if the companies don't make happy with one another and put pen to paper once more.

n the battle of Sekigahara in 1600, Ieyasu defeated the Hideyori loyalists and other Western rivals

Every daimyo was also required to spend every second year in Edo.

On the other hand, he enforced the suppression and persecution of Christianity from 1614 on.

Ader kept working to perfect his airplane, and finally, with the financial backing of the French Army, he built Avion III, a flying machine similar in design to the Eole but with a longer wingspan and two four-blade propellers. On Oct. 14, 1897, Ader tested his Avion at Satory with a military observer team present. Ader claimed that that day he had again flown, but three witnesses disagreed with each other about whether Ader actually took off and flew the Avion before it crashed.

Langley was soon experimenting with models, the first of which were powered by rubber bands

Scientists have determined that a number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accummulate in the atmosphere and trap heat that normally would exit into outer space.

Global warming is the long-term, cumulative effect that greenhouse gases, primarily carbon dioxide and methane, have on Earth's temperature when they build up in the atmosphere and trap the sun's heat. It's also a hotly debated topic. Some wonder if it's really happening and, if it's real, is it the fault of human actions, natural causes or both?

Adapted from Dinosaurs: The Very Latest Information and Hands-On Activities From the Museum of the Rockies, by Liza Charlesworth and Bonnie Sachatello-Sawyer. A Scholastic Professional Book. The last dinosaurs died approximately 65 million years ago. Although the cause of their extinction is still a mystery, climatic change, diseases, changing plant communities, and geologic events could all have played a role. Lately, dinosaur extinction theories have been the subject of much debate and controversy. A recent explanation, supported by many scientists, suggests that dinosaurs died out soon after a huge meteorite crashed to Earth near the Gulf of Mexico. A giant meteorite, they reason, could have landed with an impact that kicked up enough dust and debris to block out sunlight for a long time — leading to a deadly chain of events. Without the sun, all the plants died; without the plants, all the plant-eaters died; and without the plant-eaters, all the meat-eaters died. Sounds reasonable. But there is one problem with this theory: Paleontologists have not yet been able to find dinosaur skeletons in rocks dating to the period of impact. Some evidence even seems to indicate that all the dinosaurs had died before the meteorite hit. What is the answer? As paleontologists search for clues to support their theories, they agree to disagree.

Reasons for Global Warming Global warming can be minimized to a great extent, if we eliminate the causes which are mostly human made. The responsibility of preventing global warming rests both on individual as well as the state. In individual level we can change our practices such as minimize the usage of fossil based fuel, reduce the electricity consumption by using energy efficient appliances. Vehicular pollution can be minimized by using the public transport system. The nucleus goal is to beget the global warming under control by restricting the carbon dioxide release and other heat ensnaring greenhouse gases into the environment. On an average nearly 10000 pounds of carbon dioxide is released per year in significant countries like Canada and US. This can be immediately curtailed by becoming energy efficient. Reducing the usage of oil, coal and gasoline are one of the effective ways of preventing global warming.

To the behaviourist about clocks, a clock is simply something with such time-indicating exterior parts

The inner workings of any clock are entirely irrelevant to its status as a clock, provided they produce (or at least don't interfere with) the movement of the hands. The anti-behaviourist, by contrast, thinks of a clock as an inner mechanism which, in favourable circumstances, can cause some exterior parts to move in a way which reliably indicates the time

Elite athletes are susceptible to using drugs. They use them for performance enhancing abilities. Steroids can make muscles bigger, while amphetamines help reduce or numb pain, allowing persons to play injured. Recently, major league baseball has come under fire for drug abuse. Though not as prominent, high school and college athletes have also been known to use drugs to enhance their performance.
