Coffee Cup Calculations - Poet's Cut

Based on BBC news article "Maths zeroes in on perfect cup of coffee" http://www.bbc.co.uk/news/science-environment-37989169 Two billion cups a day we drink To stay awake so we can think Tireless workers - every nation Need a caffeine drink equation Lattes, mochas, cappuccinos Our calculator super heroes Measured, reasoned, wrote a theorem Clockwork system - mighty fearsome Divide the beans and add hot water Multiplies the bean aroma Takes away the taste chaotic Get this right - it's sums and logic China cups the theory goes Helps the smell go up you nose Cardboard mug with plastic roof Not as good, but where's the proof? But their reason's most disjoint Like whole numbers - has no point You just need a rule of thumb QED for us dumb-dumbs (Entry for "wake up with coffee or tea" contest - shortened to meet rules)
