NuVinci Bicycle

Fallbrook Technologies is starting to manufacture a bicycle with a "infinite" gears. It is called NuVinci transmission. This transmission works by having ball bearings around a hub that are kept in by a input disc (attached to the chain from the peddles) and a output disc (attached to the rear wheel). The pull handles on the front cause the whole transmission to tilt therefore increasing to a different gear deppending on the amount of tilt. To learn more about the bike click on THIS!

Big Bang

this is a website about someone's trip to Mt. Tambora.  Mt. Tambora still holds the record for the biggest volcanic eruption since 1815.  Here are some questions to answer about Mt. Tambora:

1. How far did the elevation drop during the explosion? 
   
2. When did the first and second eruptions occur? 
3. The first eruption's column was about 44 km heigh.  How heigh was the second eruption's column?
4. How hot was it when the volcano erupted? 
5. How long did the "whirlwind" last?
6. How many people in total did the eruption kill?

Good luck! 

Feel free to only answer a few of them!

a different "Big Bang"

Have you ever heard about the biggest volcano eruption in history? Some names that might come to mind are Mount St. Helens or even Krakatua, but as big as these might seem they are not the biggest. The biggest and maybe the least heard of is Tambora. In April of 1815 the volcano on a island in Indonesia erupted enough lava to cover the whole island, and killing most of their people. There was an estimated of 60,000 deaths but that wasn't the only problem. The ash from the volcano went into the air and caused some nasty problems. Because of the disturbance cattle would not eat and the crops would not grow. This caused a huge famine worldwide. The reason that the BIGEST volcano eruption is not know as well is because of the communications at the time. The only was to communicate with other countries was by ship. With this lack of communication few people even knew that there was a volcano eruption to begin with
