The Horror : Cornstarch Fingers

without comments

I recently had the pleasure of meeting Robert Deegan from the University of Michigan. He has been involved in research that focuses on the dynamics of non-equilibrium systems for many years. Recently, he has become ‘famous’ among physicists for the discovery of the so-called “cornstarch fingers”. They can be observed when accelerating a non-newtonian liquid rapidly up and down by eg. placing it on a loudspeaker.

Deegan’s setup involves some pretty expensive hardware but this weekend, I decided to give it a try myself with a couple of friends: tjansson and haalle. Below is a photo of our setup, which consisted of a signal generator, an amplifier and a 8″ loudspeaker.



The first movie we recorded shows the effect of accelerating water rapidly up and down. You clearly see patterns, known as Faraday waves, forming on the fluid surface.

iPod shuffle without iTunes

with 2 comments

I use an iPod Shuffle to listen to podcasts and music when doing sports, driving my bike etc. The iPod Shuffle is a bit different than most other iPod models since it does not have a display. The content browsing is therefore limited to skipping forward and backwards until you find the tune you want to listen to. In my opinion this eliminates the need for iTunes as a tool for organizing your music.

I have recently found an easy way to avoid using iTunes. Read on for more.

Every blogpost should have a nice image with some generic caption.
