Negative Technology

Oh, the iPhone. It's taken the world by storm, and it seems to have taken the place of its user's mind! At first the commercial explains that there's an app (i.e. application) to check the weather should you need to know the weather conditions. That is amazing in case you should need to know the weather of your destination and need to know the weather ASAP.

Then the commercial explains that there's an app for counting calories. Maybe it's just me, but I'm pretty sure I can pick a healthy meal on my own. I have this thing called a brain, and another thing I like to call self control. French fries = fatty. Do you really need an app to tell you that?

And for the commercial's grand finale, it explains that just incase you can't remember where you parked your car, there's an app for that. It's at this point that I have to stop and think for a second, a very long second. Has society become so dependant on technology that it's not even necessary to remember where the car is parked? Pen and paper people, write it down!

Need to know how much of a helpless baby you are? Yeah, there's an app for that.  Need a swift kick in the face?  You got it, there's an app for that.

Negative Technology Spoof

Below is a commercial spoof on technology and where technology is headed. Facebook is already a stalker's best friend, so why not make it a tad bit easier by adding the istalk app.

 

Positive Technology

The commercial with Kylie is a wonderful example of the great things technology offers its users. Kylie is merely 4 years old, yet she's already able to use a computer, upload her pictures and send the pictures to her family. Knowledge of technology at a young age is crucial in today's society because today's society depends on technology to function properly. Kylie is ahead of the game by learning the ins and outs of technology at a young age. She will grow with the changing technology rather than be slammed with learning about technology when she is a bit older.

The video youtube to the right features 8 year old Adam.  Adam is using technology to make a slideshow with his pictures.  He adds music and transitions between photographs.  I see a future film maker in Adam.  It's a good thing he's got technology to give him an early start!

A leap second will be added to clocks worldwide just before 2009 begins.

Not ready to let go of 2008? Tonight official timekeepers will give you one more second to hold onto, just before midnight.

 

Immediately before 2009 officially arrives, timekeepers will be adding a leap second – the first for three years – to atomic clocks worldwide.

 

According to Peter Whibley, a senior research scientist at Britain’s National Physical Laboratory, digital clocks with the ability to pick up definite leap second information will countdown to the new year as “57, 58, 59, 60, 00,” with “60” representing the leap second.

 

Whirbley explained why the earth’s erratic rotation has resulted in this need for an additional second: “The difference between atomic time and Earth time has now built up to the point where it needs to be corrected, so this New Year’s Eve we will experience a rare 61-second minute at the very end of 2008 and revelers…will have an extra second to celebrate.”

 

Determining time based off of the sun’s movement across the sky is not only a concept from the past, as astronomers still use the approach; inevitably, it has been modernized, but the sun currently stands as a tracking source for both stars and spacecrafts.


In general, the Earth is not completely reliable on keeping time. Disruptions to its core, extreme weather, volcanic eruptions, and earthquakes, along with its inconstant speed and ability to wobble, can all act as factors in affecting the length of one day. As a result, in order to align atomic time with astronomical time, leap seconds must be added every so often. This extra time helps in keeping the sun overhead at noon.
