If you’re like me, you find spirals interesting. As with many things, spirals can be found in nature, and their properties can be explained with with mathematics. I enjoy thinking about different types of spirals and what they can represent. While I cannot claim to understand very much about spirals and their applications, I have put together a few examples of spirals that I find interesting.
The Geological Time Spiral
The geological time spiral is a spiral created by the United States Geological Survey (for more information, go here). I find this particular spiral to be interesting because it gives me a new way to look at time. This image also provides perspective of the history of our planet. Pay close attention to the details of this picture; the image is very detailed and there is a lot of information contained within it. The USGS link also provides higher resolution versions of the geological time spiral.
The Ekman Spiral The Ekman spiral is one of my favorite spirals. The Ekman spiral is a spiral created by the wind and the Coriolis force in the ocean. As the wind blows in a certain direction, the rotation of the planet causes an apparent turning in its motion (to the right in the northern hemisphere, and to the left in the southern hemisphere). As the wind is deflected by the coriolis force over the ocean, the surface current moves to the right of the wind, and the movement of the current moves the water below it to the right progressively. This creates a spiral in the ocean.
Although these are just a few examples, there are many more spirals to be found. Spirals can also be found in the plant and animal kingdom. Shells like those of a snail as well as various plants naturally contain spirals. The spirals mentioned in this post are a very small fraction of the spirals in our world, but maybe they have allowed you to think more about spirals and their possible importance.
Street Fighter Alpha 2 was released for Sega Saturn by Capcom on October 15, 1996. The game was released under the name Street Fighter Zero 2 in Japan, Asia, South America and Spain. The game was popular with new and returning fans of the Street Fighter series. Its soundtrack was composed by Setsuo Yamamoto, Syun Nishigaki, Tatsuro Suzuki, and Naoshi Mizuta. In their January 1997 issue, Gamest magazine in Japan voted Street Fighter Alpha 2 to have the fourth best video game music. The music was rearranged as part of the transition from the arcade to the 32-bit system. There are 18 characters featured in this game, with each character having their own stage in addition to there being other stages. The music featured in the video shows the music from the stage where Ryu faces Sagat. In the version I am familiar with (the Sega Saturn version), the stage is a field with wheat or some other type of tall grass and flashing lightning. This song is one of my favorites from Street Fighter; I hope you enjoy it.
As you can see, I have given the page a new look. I used the Wordpress Theme Generator. It took some time of tweaking with the settings to find something that I thought worked, but I am happy with the result. I would recommend this theme generator. I am also trying a post rating plugin and a post suggestion plugin, so try them out.
Cool Mint Listerine was introduced on Thursday, March 12, 1992. The release of this new flavor was preceded by decades of research on alternative tastes and declines in sales of Listerine. The Warner-Lambert Company, which introduced the new flavor of Listerine, began heavily advertising in July of 1992 with planned expenditures of 100 million dollars. Cool Mint Listerine received the same endorsement from the American Dental Association that the original variety received in 1987, and it was marketed with the slogan “Works like Listerine. Tastes like cool mint.” Although Listerine was the top-selling brand of oral antiseptic in 1992, with an estimated third of the market, it still needed to compensate for a 21.8 percent decline in original Listerine’s sales. Over the course of the next year, Listerine increased its market share by 22.6 percent, accounting for 80 percent of mouthwash sales. By itself, Cool Mint Listerine took 11.9 percent of the market. Part of the advertising campaign for Cool Mint Listerine was a commercial in which a bottle of Cool Mint Listerine swings through the jungle to land next to a bottle of original Listerine. The commercial featured the song “Tarzan Boy” by Baltimora. The jungle setting of the commercial (which was created by Pixar), was described as a setting “perfect to talk about fresh, minty taste.”
