The Physics of Pooh !

You've heard of The Tao of Pooh, and probably seen the Tao of Physics, but after recent explorations in A/Level lessons there is much to be gained from the physics content of the tales of Pooh.

Take Tigger.  He is a fine example of a driven oscillator.  Experiments were done (hanging him upside down with and without weights  extending him; and despite much encouragement we discovered he was critically damped). He is very much dependent on the muscles in his rectum for his bounciness.   Were these to be disabled or otherwise occupied he would be bounceless. Pity the other characters did not think of this when he got out of control.  A temporary way this was achieved involved an alternative use for the North Pole........ 
For some reason further Tigger experiments were not popular with my group, and he never came back for the rest of the lesson.
A great shame, because a measurement of g was planned.
 



Eeyore did, but due to his reluctance to join in, we were unable to do much to him and further research is necessary.  We conjectured that he could be of help in fluid dynamics, a measurement device for flow rates.   He was not happy (not exactly unusual) when this was suggested as we would have to remove that ridiculous pink bow to make his tail more streamlined.
 
 
 
 

We found at this point that he had legged it to the nearest tree and was trying to smear himself in honey to reduce surface friction, in the hope that this might mean bow removal was unnecessary. Well, that was his excuse.
 

  Interesting phenomena were noted around him - a very localised cloud formation which suggests a strange temperature gradient may exist within his vicinity. He claims it is just in his nature that a dark cloud follows him but there must be some scientific reason for it.

The psychologists suggested Prozac, but that gave rather unfortunate consequences...........
 
 

Other characters were not at that point in attendance of the lesson, but things have been planned. Reports of the destruction of Owl's house are to be investigated for analysis of natural frequencies; it could become as famous as that bridge collapse that everyone who has ever done physics has had to watch at least six times.

However, listening to Owl rattling on about it might get tedious. Some suggestion was made that we investigate how feather loss would effect flying efficiency.
 

Flight seems to be a particular theme in the world of Pooh, with balloons featuringly heavily. The material of these certainly needs some investigation as its elasticity is doubtful (ask Eeyore, but remember he is sensitive about that particular birthday party).

The density of the particular gas inside them is a matter of interest; Pooh is afterall a rather heavy bear, and yet he could float away easily.  What gas was inside ?  How squeaky did voices go when the balloon burst ?  Such valuable data has been lost.
 
 

It is however possible that Piglet could provide information. He seems to squeak a lot. He did actually try to help out in gas flow experiments (observe carfeully the angle of tilt compared to wind velocity).  However, when the little chap discovered we wanted to find out the content of helium or other such gas of high gamma. Okay, I admit that's not on the syllabus anymore, but Piglet could have been assertive and just said 'no' to this. Rather than slitting a major artery.   Unfortunately there was far too much mess to do any analysis of fluid flow trajectories.
 
 

For some strange reason I was not regarded very highly by my students at this point.  Various suggestions were made. I did try to emphasise that the pursuit of physics was my main aim, and of course the benefit to their education.   I shall continue working on this project when they are more amenable.........if I get the chance.
