Don’t believe predictions that say the future is trending towards city living. Urbanization is actually reaching the end of its cycle, says logistics expert Julio Gil, and soon more people will be choosing to live (and work) in the countryside, thanks to rapid advances in augmented reality, autonomous delivery, off-the-grid energy and other technologies. Think outside city walls and consider the advantages of country living with this forward-thinking talk.

TED > Think your email’s private? Think again..

Sending an email message is like sending a postcard, says scientist Andy Yen in this thought-provoking talk: Anyone can read it. Yet encryption, the technology that protects the privacy of email communication, does exist. It’s just that until now it has been difficult to install and a hassle to use. Showing a demo of an email program he designed with colleagues at CERN, Yen argues that encryption can be made simple to the point of becoming the default option, providing true email privacy to all.

Feynman learning technique

Richard Feynman was a physicist who received a Nobel Prize for his work in quantum electrodynamics. He was notorious for asking his mathematicians to explain concepts in simple language to test their understanding.

Here his unique technique to learn new materials:

Step 1. Choose a topic you want to understand and start studying it. Once you know what it is about, take a piece of paper and write the topic at the top of the page.

Step 2. Pretend you’re teaching the idea to someone else. Write out an explanation on the paper while you describe them out loud. Like this you get an idea of what you understand and where you still have gaps. Whenever you get stuck, go back and study. Repeat that process until you can explain it.

Step 3. Finally do it again, but now simplify your language or use an analogy to make the point. If your explanation ends up wordy and confusing, that’s an indication that you do not understand the idea well enough. If that happens go back until you have mastered it. It is the process of thinking about an idea while teaching it that make the method so effective.

Once you can explain an idea with simple language and create graphic analogies, you have deeply understood it and will remember it for a long time.

And here is Feynman’s face! 😀
