Recurring Decimals…..

Yet another link…..

Lazy bum that I am – I love this ‘link to funnier/more interesting stuff with short comments’ system.

Anyway, got this in the e-mail from a colleague. Anybody who has struggled to get regular high-school/college course-related laboratory physics (or any other science) experiments to work using antiquated, partially functioning instruments will definitely sympathise with this. It starts off with:

Abstract: The exponential dependence of resistivity on temperature in germanium is found to be a great big lie. My careful theoretical modeling and painstaking experimentation reveal 1) that my equipment is crap, as are all the available texts on the subject and 2) that this whole exercise was a complete waste of my time.

….and gets funnier. This graph particularly, is priceless:

Reminds me of a much simpler experiment in high-school physics lab where we were trying to ‘prove’ Ohm’s Law using a particularly temperamental voltmeter. No matter what the actual current/voltage was, we could make the instrument show whatever value we wanted by tapping various parts of it.
