Chemists have figured out a way to change the behavior of inanimate objects and make water-repellent glasses. I find this interesting because I am a huge Harry Potter fan and I always wished I could have water-repellent glasses. They would be so helpful! Charles, OK but your post is short (49 words) and is not really connected to chemistry - 3 stars. MW

Redefining the Kilogram I found this article interesting because it left me with a lot of questions. How did the kilogram lose 50 **µ**g? How do they come up with the SI units? Why don't they measure grams instead of kilograms? Do they have a International Standard for every unit of measurement? These are just some of the questions I was left with after reading the article. I think this is relevant because we use the metric system quite often in chemistry. It's good to be informed about when things like that change because when one very important detail changes like that, a lot more change along with it.

Charles, Good questions! I like the fact that you are curious. I wonder about the kg vs g thing myself. 5 stars. MW

Motion Detectors The article, Motion Detectors, was very eye-opening. Eye-opening because I realized how often I see motion detection in my regular day. I mean, I think it's really cool that we can have this kind of technology that can be used in so many useful forms. Some uses are: automatic doors, automatic doorbells, photo gates, garage door openers, rattlesnakes with mice, bats with moths, and intruder detection in homes. And that's just naming a few! There are so many different uses out there and more are being invented. An example of modern-day motion detection might be the touch technology released by the company Apple (iPod Touch, iPhone, iPad). Whenever you move the device from a vertical to a horizontal position or vice versa, the display moves with it! So essentially I was very surprised at how frequently I am exposed to motion detection without even noticing.

Charles, Interesting connection to touchscreen technology. Not exactly the same but it is related! Awesome post! 5 stars. MW ||
