Mathematics is the topic of conversation this Wednesday at Jarbô bar.

Hearing a scientist announce their discoveries over a round of beers at a bar might sound strange. But in February 1953, those paying attention at the table of the Cambridge University laboratory team gathered at The Eagle Pub witnessed biologist and neuroscientist Francis Crick (1916-2004) enter with explosive news for his colleagues: "We have discovered the secret of life." The revelation of the double helix model for the structure of the DNA molecule captivated the world and changed the history of science.

Since then, the discovery by Crick and the 90-year-old molecular biologist James Watson has enabled countless advances, such as the mapping of the human genome. Furthermore, the casual conversation among scientists at a bar has moved beyond the private sphere and gained public status with the creation of Pint of Science, the world's largest science outreach event, which originated in the United Kingdom in 2013. Conceived by two researchers from Imperial College London, Michael Motskin and Praveen Paul, the initiative was so successful that it spread worldwide.

In the 2018 edition, more than 300 cities from 21 countries participated in Pint of Science. In Brazil, where the event arrived in 2015 thanks to journalist Denise Casatti, from the Institute of Mathematical and Computer Sciences (ICMC) at USP, in São Carlos, the program reaches its third and final day with talks on a wide variety of subjects, in 56 cities.

In Rio, mathematics, the quantum world, extraterrestrial life, and functional foods are the topics of conversation later today, at 7:30 pm, respectively, at the bars Jarbô, Teto Solar, Empório Colonial, and Bento.

At Jarbô (Rua Jardim Botânico, 1008, inside the Botanical Garden), starting at 7:30 PM, the Director-General of IMPA, Marcelo Viana, and the full professor of the Institute of Mathematics at UFRJ, Ricardo Rosa, will explain how a researcher in the field allowed the legendary Guinness to increase production without compromising the excellence of the brand. Thus, statistical inference became a billion-dollar tool.

You will also learn how differential equations are part of the phenomenon of the emergence of an attractive mug of beer. In the world of mathematical modeling, the equations translate movements of growth, stabilization, and decline that occur when brewer's yeast comes into action and manipulates a range of variables, such as sugars, oxygen, PhD, and temperature.

During the chat, Ricardo, the "father" of Colorado Demoiselle, Pale Ale Aprazível, and Vertigem da Mistura Clássica, among others, will also provide valuable information for those who dream of one day creating their own beers. Jarbô provided the space, and the public pays for what they consume.
