Day Sixty-Nine: sharing knowledge and a little love

This article from the International Herald Tribune made me laugh out loud today. It tells of a charming and theatrical physics professor from MIT, whose internet-broadcast lectures are proving quite a hit. He is known for bouncing around the lecture theatre, performing dramatic experiments with props and generally making physics fun. When Walter H G Lewin gained a cult following at MIT, the institute created a global classroom using its OpenCourseWare - and now anyone in the world can log on and benefit from his knowledge and enthusiasm for FREE. And they do. Apparently, Prof Lewin has received fan mail from India, China, Iraq and many other places, and he was No 1 in the download charts on IPhoneU for a while. It's a fantastic example of someone with a gift for teaching thinking of new ways to reach out and touch their students, wherever they may be.

Well, guess where I'm off to next? Yes, to an online science lecture - I want to witness Prof Lewin for myself and develop my own love of physics. If anyone can help me do that - something of an upward climb - then I guess Prof Lewin may be the man. (Photo from IHT online.)

(Actually, you can link to the lectures from a little box to the side of the IHT article. I've already had a peek. All 36 lectures are there so you can view them in order, or pick a subject that takes your fancy. The high res versions are more or less like being in the lecture hall yourself... though you are less likely to be hit by any flying props. Each is 45 mins, so this is something to do when you have some time, and a cup of tea in your hand...)

Auditory Illusion

I read about an interesting auditory illusion this morning on Mind Hacks. According to Wikipedia this is an example of a Shepard Scale.

A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the base pitch of the tone moving upwards or downwards, it is referred to as the Shepard scale. This creates the auditory illusion of a tone that continually ascends or descends in pitch, yet which ultimately seems to get no higher or lower.

Here is an example from YouTube, which you just need to listen to and then replay. Here is a link to the original article.

It's Alive!!!!

This is a strange piece of video but is fascinating at the same time in my opinion. I'm sure you are all familiar with the non-Newtonian properties of corn starch mixed with water. If not perhaps you'd better read this before continuing....Finished? Good.

So somebody had the inspired idea to pour some on to a metal tray and hold it over a sub-woofer that was thumping out a meaty base line. The liquid behaves almost like it is alive. It's actually quite strange. Enjoy!
