Ep 154: Blogging, podcasting, royal jelly and using chocolate to determine the speed of light

Over the Easter break, I spoke with Lish Fejer on ABC 666 Canberra on her Experimentarium segment. We spoke on various things to do with science blogging and podcasting, and matters Easter related including:
  • Royal Jelly (the Royals were in town, a great link if ever I've seen one),
  • Determining the speed of light using your microwave and left-over Easter chocolate.
To learn more about Royal Jelly, tune into Episode 137: Can your environment change your DNA in which I spoke at length with Professor Ryszard Maleszka from The Australian National University’s College of Medicine, Biology and Environment about the molecular differences in over 550 genes in the brains of worker and queen bees that are a result of the queen bee eating royal jelly at a young age.

On determining the speed of light using a microwave, see the post Instascience by Tom Gordon in which he uses paper. We used chocolate and it worked pretty well, albeit very messily. You will enjoy trying this at home, and failing just gives you another shot! Note in the broadcast I mentioned that the speed of light was 2.97 x 108 when it's actually 2.99792 x 108 (please forgive such a grievous error...)

Listen to this show here - the audio is courtesy ABC 666 Canberra:

Here is a nicely produced video on how to do this - I started out making one and made a mess of my kitchen.


  1. I have suffered from herpes since I was young. It is only the last few years I got to know so I started to look for a cure. I went to several hospitals but to no avail. So I came here online to see if I could find a cure so I came across a page here a man was sharing testimonies about Dr Ohikhobo for his natural herbs cure for herpes so I decided to give it a try it only took two weeks of me taking his herbs and I was completely cured from herpes. contact Dr Ohikhobo today if you want to be cured from herpes or any kind of disease too .

  4. To find out how to measure the speed of light using a microwave, check out Tom Gordon's Instascience piece, where he utilizes paper. It was really messy, but it worked pretty nicely with chocolate. Attempting this at home will be enjoyable, and if you don't succeed, you always try again! I have to admit that I wasn't quite sold on the concept of a theater "tweet night" at first. I'm sure that a lot of readers will find this information useful. Thank you for sharing your expertise and experience.
