Ever since I heard about this blogging assignment, this was the first idea to come to mind. I used to play the game Super Mario Sunshine frequently in my childhood. The game stars Mario in a tropical setting, using a water-fueled jetpack to hover over large gaps for a few seconds. Using this jetpack, he can hover over characters and spray water on them to clean them off. Sounds harmless enough, but I wanted to see just how powerful this water pack could be. Many have assumed that Mario weighs somewhere around 165 pounds, so I will be using this for my calculations. Converting this to kilo

A few days ago scientists confirmed that there is liquid water on Enceladus one of Saturn's 53 or so moons. The surface of Enceladus is covered in a thick sheet of ice but NASA's Cassini spacecraft which has been orbiting Saturn since 2004 has sent back images of geysers of ice, water vapor and organic compounds shooting out from cracks in the ice at the south pole of Enceladus. This was the first sign that there may be liquid water below the ice. Also, NASA noticed slight changes in Cassini's trajectory and the wavelength of it's radio signals which suggested that Enceladus has a greater mass

How is Tap Water Safe if the Supply Pipes Get Leaks?
pavelow posted a blog entry in Blog Having Nothing to do with Physics
This blog was inspired by this fact: The New York City water supply system leaks at a rate of up to 36 million US gallons (140,000 m^3) per day. Source: http://www.nytimes.com/2008/11/23/nyregion/23tunnel.html?pagewanted=2&_r=0 Our water is extensively purified, and is completely safe to drink, but how can it be safe if some of the biggest supply pipes have holes all over? Besides the full -on sanitation of the water, one part of the solution is that our water supply contains some residual chlorine and other chemicals that stop bacteria growth from occurring in tap water. Any pip -
Water is strange. Unlike most compounds, its solid form is (normally) less dense, and of a larger volume than its liquid form. Because of this, its very difficult to compress water, because normally there isn't really anything to compress it into. But the story of ice is a bit different from the snow and hail we see falling outside of our windows during these winter months. In fact, ice has many different forms, depending on the conditions it forms in. The ice we commonly know is called Ih - a common ice type with a hexagonal structure. But as you can see from the picture, there are ma

Have you ever been doing chores or showering and wondered how the water comes out of the shower head or faucet? Well, if you have, this blog entry will explain the basics of how they work. A faucet is a device that regulates the flow of water in a system, such as a house or school, and without them, water would be flowing constantly out of pipes be almost useless in everyday life. SImple machines work to control the pressure and flow of water, including levers and screws. The pressure inside of water pipes is much higher than the pressure of the air outside of the tube, which allows the
