Coffee Cup Calculations

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 No longer need barista instinct Random variations extinct Future bistros turn bizarre Robots running coffee bars 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? Coffee can't be served alone You don't need maths - it's just well known Donut, muffin you could try Bagel, biscuit, slice of pi But their reason's most disjoint Like whole numbers - has no point You just need a rule of thumb QED for us dumb-dumbs
