When our parents imagined the world that we would live in now, they never dreamed of all the technology that we would have at our fingertips. The predictions they did make involved effortless communication, ease of learning and cities on the moon. They probably didn’t think we would be using more computing power than as on the first space shuttle to play little games involving shooting birds at egg-stealing pigs.

While the entertainment possibilities of your iPhone are just about endless, don’t forget to download a few of these apps so that you can expand your mind when you want to take a break from Angry Birds.

Top 3 iPhone Apps To Learn How The World Works

Khan Academy

Khan Academy is a non-profit that seeks to enhance learning by using technology. The video library currently has 1,000 videos and counting. You can learn about everything from math, science and chemistry to economics, banking and the financial crisis by watching the video lectures.

The app also lets you interact with your Facebook friends and post on discussion forums so that you can continue your learning after the lecture is over. You can also cache videos so you can learn when you do not have an internet connection – a real plus! Like Khan Academy itself, the app is completely free.


Wikipedia has revolutionized the way we find information on the Internet, and now you can have Wiki on your iPhone as well. The app is designed to simply and quickly bring you the Wikipedia experience of learning about whatever it is that crosses your mind.

It takes you on a journey you’d never expect. You may think to yourself, “I wonder how digital scales work?” and tap your app, start reading and then find yourself clicking on miniature load cells, then load cell calibration and somehow, hours later, end up at a history of the Arizona Cardinals. As we have come to expect from Wikipedia, the app is available at the low cost of absolutely nothing.

WorldBook – This Day in History

This app from the World Book Encyclopedia gives you a few historical facts every day with an interesting hook. They are events that took place on this particular day in years past. If there’s a particular day – like your birthday – that you want to learn more about, you can navigate through and learn what historical events the anniversary of your birth celebrates.

A scheduled update will add pictures, video, audio, famous speeches and text from articles. You will even be able to play the national anthem of a country on the anniversary of their becoming a nation. At just $0.99, it’s a steal.

There’s nothing wrong with wasting time playing games or listening to music on your iPhone, but with a few of these apps downloaded you can broaden your horizons and learn more about the world around you.
