| Guinness Storehouse - "Tick Followed Tock" - Guinness Advertisement 1999 |
As the clock winds down on 2025, as we toast the old year
and look forward to the new, I find myself remembering my mathematical visit to the
Guinness Storehouse in Dublin, Ireland earlier this year. Mathematics certainly provides great
excuses to visit a wide variety of places!

| A Visit to Guinness Storehouse - Dublin, Ireland |
The Storehouse is a 7-story extravaganza of all things Guinness from ingredients to brewing to adverisiting to shipping and more! It includes a restaurant and multiple bars, including the Gravity Bar that makes up the entirety of the 7th floor, which has one of the best views over the city of Dublin. Most tickets include a pint in the Gravity Bar at the end of your tour.

All of my travels involve mathematics in some way, so what's the math connection here?

Guinness faced a practical quality-control problem: testing barley to ensure consistent brewing required destroying some of the product; therefore, only small samples could be used. Traditional statistical methods required large sample sizes and didn’t work well with such limited data.
William Sealy Gosset, a brewer at Guinness with training in mathematics and chemistry, developed a new way to draw reliable conclusions from small samples.

This method became what we now call the
Student’s t-test. The name is due to a company policy. Guinness allowed Gosset to publish his work only under a pseudonym. The name he chose to use was “Student.” That pseudonym is why the test still bears that name today.

More than a century later, the
Student's t-test still matters because it remains one of the most widely used tools for making sense of small data sets, from scientific research to medicine, economics, and more! So, if you raise a glass this New Year's Eve - especially if it's a pint of Guinness - be sure to remember the name William Sealy Gosset.
