Should Airplanes Look Like Birds?

Currently a Boeing 747 gets 0.2 miles per gallon; a more aerodynamic plane would reduce drag as it cruises through the air and increase lift, which translates to better fuel economy.

Like their automobile counterparts, airplane engineers have been looking for ways to safely send those 70-ton metallic birds into the air on a leaner fuel diet to cut down on carbon emissions and rising transportation costs. Earlier this year, engineers Geoffrey Spedding at the University of Southern California and Joachim Huyssen at Northwest University in South Africa put their heads together to tackle that airplane fuel efficiency conundrum. After reconfiguring the typical plane design in order to maximize the plane’s aerodynamics, they came up with a brilliantly basic answer: Airplanes should look more like birds.

Should you defend the free speech rights of neo-Nazis?

Former president of the ACLU Nadine Strossen discusses whether our society should always defend free speech rights, even for groups who would oppose such rights.

Harness the Power of Calm

Tap into the "Rest and Digest" System to Achieve Your Goals

Big Think Edge
  • In the fast-paced workplaces and productivity-focused societies many of us inhabit today, it is easy to burnout.
  • Emma Seppälä, a Stanford researcher on human happiness, recommends tapping into the parasympathetic nervous system instead—"rest and digest"rather than "fight or flight."
  • Aiming for energy management rather than time management will give you the resilience you need to excel at the things that really matter in your life and career, rather than living "mostly off" by attempting to seem "always on."

Where the evidence of fake news is really hiding

When it comes to sniffing out whether a source is credible or not, even journalists can sometimes take the wrong approach.

Sponsored by Charles Koch Foundation
  • We all think that we're competent consumers of news media, but the research shows that even journalists struggle with identifying fact from fiction.
  • When judging whether a piece of media is true or not, most of us focus too much on the source itself. Knowledge has a context, and it's important to look at that context when trying to validate a source.
