What cant math do?

Discover magazine has a top 100 stories list each year. These stories include new scientific breakthroughts, fun facts about math, and many other cool ways of relating these topics to daily life.

This particular entry talks about how combining a GPS system with mathematical methods could help fix traffic jams. If you think logically about a traffic jam, you realize it is pretty simple. After the crash or what not is cleared, the “jam” moves steadily backwards, as the amount of cars piling up is doing so at a faster rate than those who are leaving the jam in the front.  The correct speed of incoming cars to leaving cars would have to be reached to allow jams to disperse more quickly.

iPhone issues

Yellow screens, faulty reception, and slow upload speeds are just a few of the problems with the new iPhone 4. Early adopters to the new device may be unable to control their anger with Apple. For those iPhone users who need to control their frustration, why not use the KenKen app from the iTunes store? KenKen can always take your attention away from external distractions. Once you’re concentrated on a KenKen puzzle, nothing can distract you, not even one bar in the upper-right hand corner of your cell phone.
There are three versions of KenKen in the App Store. There’s a free version to download so you can get a taste of KenKen. Then when you crave more puzzles, there are two premium versions. KenKen: Train Your Brain provides a ton of additional puzzles, and the KenKen Pro app provides even more and allows you to write in the numbers using hand gestures.
Apple is having a tough time coming up with a solution. They tried software updates, but it doesn’t seem to be working too well. Before you know it, they might even call for a recall. So, before your shiny, new iPhone needs to be sent back for repair, play as much KenKen while you can. When the time comes that you’re waiting for your iPhone to be repaired, if you have an older iPhone lying around, all the apps will work on that one too. Or, if you have an iPad, just double up the pixels and the game still looks crystal-clear.
So when you’re not video chatting with other disappointed iPhone 4 users on FaceTime, open up a KenKen app and you won’t even notice that your concerns for the iPhone issues have faded away.

KenKen and Alzheimers

There are tons of researchers debating whether or not brain games and mental exercises such as KenKen and Sudoku can actually help the brain develop, and thus “beat” Alzheimers. A study done at East Carolina University studied the effects of daily casual mentally challenging video games. The results were promising. As opposed to video games that require little logic and reasoning, games such as Bejeweled, a simple logic game, helps the brain promote active participation. This type of participation cannot be found in activities such as watching TV or playing a mindless video game.

The brain needs exercise just like the body does. If you use and challenge your brain often, it will be healthier for longer. Pretty simple huh?

One mans response to KenKen

After going on about how he loved, then got bored of Sudoku, and the same for Kakuro, this guy found KenKen…

Happily, just as I was getting disillusioned with Kakuro, KenKen stepped into my life. It arrived in the form of a book–a review copy of Will Shortz Presents KenKen Easiest Volume 1 from St. Martin’s Press. It is written by Shortz and Tetsuya Miyamoto, the Japanese math teacher who invented KenKen. “Ken” means wisdom in Japanese, thus KenKen means wisdom squared–or perhaps cleverness squared, depending on your translation.

It took me about 30 seconds to grasp the rules of KenKen and another 30 seconds to get sucked into the book. Shortz, The New York Times’ crossword puzzle editor since 1993 and probably the most famous puzzle guru around, praises KenKen as a puzzle that’s easy to learn yet spans a range from simple to very difficult, and he’s right
