Social Studies- Advancements

Throughout the years, the advancement in technology has greatly affected society. Computers have probably had the greatest impact on society. This is because computers started out as simple gadgets and now are so modern with their hardrives and applications. A computer is part of most people's daily lives. Everywhere you go it is rare not to see a computer in the United States. Nowadays there are so many ways to be connected with others, share ideas and thoughts through the Internet. It is like having everything you need at the tip of your fingers however, years ago the computer hadn't even been invented. Knowledge, ideas, and thoughts are spread worldwide through the Internet. As one of the advancements in technology, computers have greatly impacted the society.

MATH BLOG-Fibonacci Sequence

In class a little while ago, we learned about the Fibonacci sequence and the Golden ratio. Over seven hundred years ago a Italian mathematician, Fibonacci created the very famous Fibonacci sequence. The numbers 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 and so and so forth is his pattern. As you can see, to create the next number you take the sum of the two numbers before it. This sequence hadn't been named until the 19th century when a French mathematician, Édouard Lucas named it. After studying the Fibonacci sequence, he began to relize that any any pair of consecutive numbers is closer to the golden ratio-1.618. . .). Also as the numbers gets higher, the closer it is to the golden ratio. In the image shown below, Fibonni's sequence even comes across nature. Fibonacci's sequence is very important and is found everywhere.

No Water On Mars?

Just yesterday by a group of scientists was it discovered that there is no water on Mars. In 2006 was is announced that the images indicated water to flow on Mars and now thoughts have changed. Apparently, it is found that it was actually a landslide of sand and gravel. New images and computer simulations strongly display that it is not water, but a landslide. The landslide can explain the bright deposits in gullies, thought to be recent water flow. Water flows did not match the computer models, but showed a dry, granular material such as sand. The landslide was a perfect match with the model. Another theory scientists have is it could be thick mud with fifty to sixty percent of sediment similar to molasses or lava. "The simplest explanation is that it is dry, granular flow," Pelletier said. "We think that the simpler explanation is probably the correct one." This is a quote one the scientists working in the project had said.

EXTRA! EXTRA!- Check It Out

The website http://www.sciencedaily.com/ is a great place to find several articles science related. In fact, this website is all science which is one positive aspect about it. This site gives updated news and many articles on different science related subjects. Another good thing about the website is there isn't anything irrevalent or off topic. An aspect I don't like is when they show the article, the information is all cramped up in a little spot with the rest with other articles or information. The site can be used in understanding new scientific discoveries or just checking science news. You can also find some information of the many science topics here. I would recommend this site for future use if you need to write something on current events or learn something interesting.

Matter: What is It?

Ever wonder what the universe is made of? One answer, Matter. Substances such as wood, metal, water are all forms of matter. Even we are made out of matter. Matter is anything that has mass or volume. Properties which describe matter can be specific or general. However, all matter has the same general properties of mass, weight, volume, and density. The most important property of matter would mass. Mass is the amount of matter in an object. The amount of mass of an object is constant unless matter is added or taken away from the object. Moving an object from one place to another doesn't change its mass. Because of mass an object has weight. Weight on the other hand is not constant like mass. It changes. For example your weight can differ after a large meal. Weight, however can change from location to location. As we may know a ball thrown in the air must come down. This is because of gravity. The ball must come down from the Earth's force of attraction of all objects. Without you knowing it you are attracted to several objects like paper and books. The gravitational pull is too weak for us to notice. Due to Earth's massive size the gravitational force is much more greater which is keeping us from floating into space. An objects weight is determined by the pull of gravity. You weigh less at the top of a mountain than you do at sea level. This is because you are farther away from Earth than you are at sea level. The metric unit for measuring weight is the newton(N). Last two general properties of matter are volume and density. Volume is the amount of space an object takes up. Liter(L), milliliter (mL), and cubic centimeters (CM3) is what volume is measured in. Both liter and milliliter are for liquids as cubic centimeters are for solids. The last property of matter would density. Density is the mass per unit volume of an object. This property lets us compare the different types of matter. To find the density you must divide mass by volume. Density is referred as grams per milliliter(g/mL) or grams per cubic centimeters(g/cm3). Currently we were learning about the general properties of matter.
Mass
Density=---------
Volume



I believe it is important to know what is in our surrounding and how to tell the difference between objects. For example if you wanted to buy a large pack of an object instead of a large pack we could tell the difference by their two masses. Without us even knowing that matter is everywhere.

Honey Help With Cough Better than Cough Syrup?

Could it be? Honey, a sweet sugary substance can now help with cough and even with sleep. Well, a couple days ago, a research team at Penn State College of Medicine has found an interesting discovery. Honey may just work the same or better than over-the-counter medicine. They have been testing several children to see what the outcome might be. The results show that buckwheat honey might be the best in relieving symptoms rather than any other cough syrups. Knowing this can be very helpful especially for parents with kids under the age of six. Recent studies have shown that cold and cough medicines are not safe unless the child is above six years old. Due to the lack of effectiveness and side effects, doctors recommend to stay away from over-the-counter medications. Dr. Ian Paul, the lead researcher has warned not to give honey to infants of one year of age or younger because of the harmful risks such as infantile botulism. Honey not only helps with cough, children can now sleep soundly without getting up by their coughs. A food we all have can now serve as a safe and easier way to treat annoying and itchy coughs. There is only one question that has not been solved. Do all kinds of honey work just as effectively?

In my opinion, this discovery must be a big helper. Firstly, with a lot of the cough syrups recalled, it is a safer and more effective way to treat cough. Parents don't have to cautious so if there child/children took cough syrup because honey can't really hurt you. In addition, who doesn't like something sweet as medicine rather than the sour flavors they have nowadays. Now we can sleep peacefully without waking up just from a dry cough. I believe this is useful especially now during the winter.

I'm A White Tree Frog!!

Also known as the Smiling Tree Frog or Dumpy Tree Frog due to the nature of its appearance, this frog is a very hardy creature and a favorite pet of amateur frog owners, although some pet owners complain that they are not active enough. These frogs love to eat, which can make them quite fat, hence their "dumpy" appearance. Unlike many frogs, these frogs do well with other frogs of their species and are fairly friendly. They like a warm and moderately humid habitat and eat larger insects like crickets, cockroaches, locusts, moths and beetles.
