Physics Department Exponential Decay Evening

Physics Department Exponential Decay Evening

Late on Wednesday evening November 11th, all 6.2 physicists assembled in the Department. Their mission: to investigate whether the amount of froth on the top of a glass of Carling lager decays exponentially. 

In most cases the conclusion was a resounding: yes. 

Readers with a thirst for technical detail may be interested to know that the decay constant of Carling froth was found to be -0.015 Hz (+/- 0.005 Hz).

Readers with a middle-order grasp of the mathematics of exponential decay will know that this is equivalent to a half-life of 46 seconds. 

Next year: Radley Champagne may be analysed.

An enjoyable evening was had by all (accompanied by EJT, DJP, ACN, JPJD & KAM).
