Music and MathBy: Nathan ChessEver wonder why some note combinations sound pleasing to our ears, while others make us cringe? To understand the answer to this question, youll first need to understand the wave patterns created by a musical instrument. When you pluck a string on a guitar, it vibrates back and forth. This causes mechanical energy to travel through the air, in waves. The number of times per second these waves hit our ear is called the frequency. This is measured in Hertz (abbreviated Hz). The more waves per second the higher the pitch. For instance, the A note below middle C is at 220 Hz. Middle C is at about 262 Hz.Now, to understand why some note combinations sound better, lets first look at the wave patterns of 2 notes that sound good together. Lets use middle C and the G just above it as an example.

Now lets look at two notes that sound terrible together, C and F#:

Do you notice the difference between these two? Why is the first consonant and the second dissonant? Notice how in the first graphic there is a repeating pattern: every 3rd wave of the G matches up with every 2nd wave of the C (and in the second graphic how there is no pattern). This is the secret for creating pleasing sounding note combinations: Frequencies that match up at regular intervalswww.youtube.com/watch?v=JtSYIJb9UkwThe Math SongNicholes articleHelpful Study TipsThere are many ways to study for math and one of those ways whether you no it or not is always right in front of you. Studying is as simple as taking your math book, sitting down and practicing random problems from the math section you are working on. Math is not always the most fun thing to practice but with the help of your friends from school it can be more fun then you think.When people dont understand how to do math most of the time they are embarrassed to say that they dont understand because they think people will make fun of them. If you are one of those people then the first step is to admit that you have a problem and to get help. If you dont want to say out loud that you dont understand wait until the teacher is through and approach her at her desk. Another way to study for math is to take notes in class. Even if the teacher says you dont have to take notes take them any way. It makes it a lot easier to study and no what you are doing when you have the exact answers sitting in front of you. To find more math tips Google them or go to various math sites. There are 20 people on a bus heading for New York City, three of the people make stops along the way, five of them decide to go straight through, and the rest of them decide to give up on the trip and just go home. How many people make it to New York, what group will make it there first and how many people go home? 8 people altogether will make it to New York City and The group of 5 make it there first. And then 12 people go home. Nichole Secilia

Careers using mathThere are a lot of careers using math. In every job, you wave to use some type of math. Whether you are working at McDonalds or working to rebuild a new skyscraper, you will use some type of math. Sometimes it is easy and sometimes it is very complicated. It is used to determine the salary or to determine how big something is. One career that uses math a lot is drafting. In Drafting, you have to prepare drawings for many things. You design buildings and structures. You also draw blueprints for companies. After the company gets a drawing request, then the drafting team starts working on it. It could take hours, days, weeks, or months. Drafting & Design is a career field that uses a lot of math. Another career that uses a lot of math is Culinary Arts. In culinary arts, you have to know the exact measurements for a recipe. If you get a measurement wrong, then the recipe is wrong. You could mess it up by the slightest measurement error. Recipe measurements could be doubled or tripled also. You will have to adjust the recipe to make the required servings. A big career that uses math is banking. You need to know how to do bank transfers. If the banker makes a mistake, then the account he/she is working on will be messed up.
