Episode 32: Sailors take warning with Reuben and Steve van Breda

So. Why is the Sky blue? Do you know the answer? Do You? Are you sure? Could you explain it to a 10 year old kid? No? Well then have a listen!

Reuben and his dad Steve are our guests this week and we explain why the sky is blue. we have SUPER FUN! We talk about why the sky is blue, and what skies on other planets would look like… also… how 3-d glasses work.

Amanda Bauer (astropixie) is one of our experts! Ken Clark is the other. But we lost ken midway through the episode. :( I’m sorry, Ken.

Physicists: Amanda Bauer, Ken Clark

Intro Music: Ted Leo and the Pharmacists

  1. I thought that green was the color for which we can see the most shades. Am I wrong? Also, I have always had a fascination for qualia– the philosophical term for the subjective things we experience for which we cannot ever know whether others experience in exactly the same way as we do. I’ve never heard it so closely tied to physics. Huzzah.

    • I believe that you are correct in believing that we see more shades of green than any other color, but I believe that is because the green we see is not “how intense is the light hitting our green receptors” but rather “how intense are our green receptors being stimulated when compared to our red and blue” which means that we are actually able to use /all/ of our cones to detect the various subtle difference in light being reflected off plant leaves.

  2. Great show as always, cut through common misconceptions with your usual skill.

    Question for Steve regarding the comment about the war over the colour of the sky: are you a fellow member of the Bayesian conspiracy? 😀

  3. Ben, I feel the need to point out that modern 3D movie polarization, RealD for example, uses circularly polarized light, and its glasses don’t act quite the same as linearly polarized glasses. Though they will still block or allow the light from the other lense, depending on the arrangement of the lenses. Also, it is still quite fun to play with them if you happen to forget to return them. Funky colors on car windows for instance, which if my memory serves me do change depending on how you hold your head.

    Shrug, perhaps you could do an episode about polarization, ’cause it’s crazy and awesome and most animals (including humans, though just barely) can detect it to various extents.

    • OH WHAT?
      really!!?! they use circularly polarized light?
      that’s AWESOME! oh man. i had no idea it was so cool.

      do you know how they project it on the screen?
