WAVES!!!

Lately, in science we have been learning about waves. There are two types of waves: Transverse and Longitudinal. In Tranverse waves the crest is the highest point and the trough is the lowest point. The center of both points is called the rest position. The wavelength is the distance between crest to crest and trough to trough. In a Longitudinal wave a compression is when the wave is packed up together. A rarefraction is when the wave is spread out. On the web I found out that the definition of a transverse wave is: a wave that move the medium at right angles to the direction in which waves travel. I also found out longitudinal waves really mean: are waves that have vibrations along or parallel to their direction of travel; that is, waves in which the motion of the medium is in the same direction as the motion of the wave. Mechanical longitudinal waves have been also referred to as compressional waves or compression waves. I really can't wait to learn more in this topic!

Barack Obama, The New President of the US

As everybody knows, there is a new president in office.... BARACK OBAMA!!! Well, as I was doing research, I came across a article called: "Obama's Fast Action on Financial Regulation: Report". This article talks about how Obama plans to fix the countries financial regulatory system. They plan on doing this by making the mortgage brokers, credit raging regencies, and, hedge funds more harsher. In the following quote it shows how the people want to delete the conflicts about interest at credit rating :"...officials want rules that would eliminate conflicts of interest at credit rating agencies that gave top investment grades to the ultimately shaky financial instruments that have been one source of market turmoil".
After I read this article I really had some comments and questions. My first on this that a lot of people are going through hard times and with the economy at the worst point ever they should give it a try if it will help the economy. I also have a question about one of the terms in this articles: what does hedge funds mean?". Another question I would like to ask is when this plan would be put into play.All in all, I would like to see the outcome of this plan.
As my interest grew I decided to read another article. This one was called: "Stocks eye Obama, Fed, earnings". This one talks about how the statement of the Federal Open Market Committee's will be heard by investors and they will try to use that to help Wall Street. It also says that a recovery package in Washington worth of $825 billion will be observed. Michael Sheldon has said: "For investors, a lot is riding on the upcoming stimulus plans,".
I have a lot of comments and questions on this article too. I really believe in the quote Michael Sheldon has said because our new president has a lot to fix.IAlso wonder about how long it will take until the economical crisis is better. Well until then we Will just have to wait. I mostly wonder about what Obama will do first as president.

Where are Saturn's Rings Going???

Lately, if you have seen Saturn's Rings, you probably have noticed something very different. This is because it appears that Saturn's Rings are disappearing. Some people may not believe this because Saturn, the sixth planet from the sun, has been known for it rings. The truth is, that about every 14 to 15 years the planet is tilted. So, Earth is only able to see some of the ring's edges and maybe some of then might even look like they have vanished. In the 1600's this same situation stumped Galileo, he later called it: "ring plane crossing". This means that Saturn rotates the sun every 29.5 years, on the other hand, the equinox for the Earth happen every six months. On the day, September 4, 2009, NASA says Saturn's rings can not be seen from the Earth. This means you better get a good last look at Saturn's Rings because their not going to be around for a while!!!
