How Small Are We in the Scale of the Universe? - Alex Hofeldt

In 1995, scientists pointed the Hubble Telescope at an area of the sky near the Big Dipper. The location was apparently empty, and the whole endeavor was risky – what, if anything, was going to show up? But what came back was nothing short of spectacular: an image of over 1,500 galaxies glimmering in a tiny sliver of the universe. Alex Hofeldt helps us understand the scale of this image.

Why Music Makes the World Go Round

Music is an expression of human experience and therefore, everyone has a love for a particular kind of music. Music is found in many areas of our life including presidential inaugurations, graduation ceremonies, weddings and funerals. The ambiance in a room can be changed by adding some music - some upbeat sounds in church or soft music at the dentist office can transform the environment. There are different genres or styles including classical, jazz, hip hop, rap, rhythm and blues, rock & roll, country, folk, bluegrass, metal, world new age etc. The reasons why it makes the world to go round include:

· Music guides the emotions

Whether we know it or not, it plays an important role in our lives. It easily affects our emotions whether we are aware or not. An individual only needs to think about the music heard on a particular movie soundtrack. Although a person may be aware of the dialogue, the costumes, the scenery, the action and special effect, it supports all and guides the emotional context. When you consider some of the best movie, music plays an active role. Even in bad films, music holds the story together. It is so important to movies that the studio executives often scrutinize it to determine the effects generated by a particular scene.

· Music is important in advertising

TV programs have musical underscores. Furthermore, many of the commercials use it to sell their products - the commercial feature tunes that remain engrained in our memories. This makes it possible to remember a product resulting in making a purchase.

· Music is business of many organizations

Radio in particular remains relevant as a result of providing music most of the times, seven days a week. Different radio stations offer the tones in different styles imaginable to appeal to the listeners. Record stores too are in the business of selling music. Therefore, they remain relevant as long as they offer music that is appealing to their niche market. Giant arenas or large concerts remain relevant to the thousands who gather by making it possible to share the experience with the audience. If you are to generate a high return on investment it is important to know exactly what to present.

· Music develops the brain

Singing and making melodies plays an important role in developing the brain fully and extensively. This is particularly the case in the early years. Music helps to make an individual brighter, more logical, more intelligent, more capable and more rational. According to further research music improves the study habits as well as test scores.
