So, be a chemist. Fairy muff.
Interestingly, the t-test, probably one of the most relevant pieces of mathematics in modern science, was invented by Gossett in the Guiness brewery in Dublin in 1908.
The problem was that for testing the batches, the sample size was too small for the estimate of the standard deviation to be consistent, so the distribution was wider than would be expected from a Gaussian normal distribution. So, the lad used resampling from a bag of a thousand chicken bones (measuring the lengths) to derive a distribution. Somehow, the mathematical underpinnings were later defined properly by Fischer.
