Watching TED Talks is a popular pastime at CN&CO. We visit TED.com regularly to clear our heads, have a laugh or get inspired. TED Talks open our minds, spark new ways of thinking and can lead to some very interesting conversations. Each week we pick a favourite and publish it on a Tuesday, because we like how “TED Talk Tuesday” sounds. This week’s talk was posted by Rob Christian. Here’s why he chose it:

“Using science and mathematics to take complex ideas and represent them simply appeals to me – and while the speaker makes the point that his figures should be taken with a pinch of salt, this talk helps explain how economics can affect everyone in the world.”
