Isaac Newton's beer mug to go on show in Royal Society exhibition in London
The wooden mug will be on public display at the Royal Society, in central London, from 4 March, alongside items including Newton's greatest work, the Principia, and the scientist's death mask, which was prepared shortly after his death to serve as a likeness for sculptures.
The exhibition is the culmination of 20 years of work by the scientist Carmichael Wallace and the historian Stephen Snobelen, who pieced together the mug's history through letters, genealogical records, family wills, magazines, newspapers and even a poem.
Their research suggests that Newton only drank beer sparingly and instead, the mug points to his use of the beverage in his work. The duo's workings suggest that his best-known work, the Principia, may have been written in his homemade ink in which beer was a key ingredient.
Newton gave the wooden flagon – a type commonly used for beer-drinking – to his roommate of 20 years, John Wickins, who also acted as his occasional laboratory assistant. The mug was found with other belongings at his home at Trinity College, Cambridge.
Their research also highlights Newton's beer-related experiments, which included the study of fermentation, as well as his use of beer in the writing ink, which is still readable today in his notebooks and correspondence. Newton wrote two ink recipes, both likely penned in his beer-based ink.
Less is known about Newton's drinking habits. According to his lab assistant, Humphrey Newton, Isaac drank beer and ale with meals and only sparingly. However, there are many references to beer, ale, cider and wine in Newton's surviving papers, including household inventories, as well as discussions on the best variety of apples to produce good cider in his correspondence with Henry Oldenburg. Newton recommended redstreaks.
Snobelen said: 'The mug was venerated by the Wickins family because it was owned by Newton. It was a kind of holy relic.
'Although chemical analysis of the ink in Newton's voluminous manuscript corpus has yet to be carried out, many 17-century authors used beer as a solvent in their homemade writing ink. Newton's two surviving ink recipes confirm that he followed in this craft, at least while he was at Cambridge.'
Keith Moore, the head of library and archives at the Royal Society, said: 'We like to reflect upon past science, but a beery vision of Sir Isaac Newton is a new one for the Royal Society. According to his friends, the great man could be quite convivial, but I can't see him drinking too much from his flagon while fermenting his head-spinning ideas – as a scientist, Newton was no mug.'
The wooden 'pint flagon' – as James Wickins, John's grandson, called it in the Gentleman's Magazine in 1802 – was publicly exhibited on at least three occasions, last in 1865.
Newton was elected to the Royal Society in 1672, 12 years after its founding, and was its president from 1703 until his death in 1727.

Bert Wraith obituary
My father, Bert Wraith, who has died aged 93, was a metallurgist and expert in the dispersion of gases in metals, a key process in refinement. He developed a method for studying bubbles injected into water that led to the design of useful processes for metals, including the idea of a cyclone to clean liquid metals. In 2018 he was part of a group awarded a Royal Society prize. This was for work done at Swansea University on a laser-based system enabling the continuous monitoring of molten metal during the steelmaking process without the need to shut the furnace down. Born in South Shields, Bert grew up in York, where he went to Nunthorpe grammar school, Bert attributed his curiosity to his father, Albert, a locomotive fireman who fostered in him a passion for engineering, travel and steam trains. His mother, Dorothy (nee Watson), was a homemaker and keen bridge player. Bert graduated in metallurgy at Leeds University in 1954, then travelled to Nkana-Kitwe in Northern Rhodesia, now Zambia, to work as a metallurgist for Anglo American, smelting and refining copper and cobalt. His love of Africa never left him. He returned to the UK in 1957, and, after doing his national service at the UK Atomic Energy Authority, Aldermaston, married Marie Goodenough, a sculptor, in 1958. Bert then began teaching at Newcastle University, where he completed his PhD and established a research unit devoted to understanding the process of metal refining. He mentored 17 PhD students in the UK and Zambia, many of whom became close friends. He also enjoyed lengthy collaborations in Canada, most notably with the Australian metallurgists Ralph Harris at McGill University, Montreal, where Bert was an adjunct professor, and Phillip Mackey, whom he latterly worked with on the history of metallurgy, including the sheathing of the copper-bottomed ship Edwin Fox. Bert retired from his senior lecturer post at Newcastle in 1996. At 85, he was invited to join the 'Energy in Store' initiative with the Science Museum to improve access to scientific artefacts. A proud Geordie, Bert was a supporter of the North Eastern Locomotive Preservation Group. He was also a kind and modest man with a wry sense of humour and a social conscience. He was diagnosed with Parkinson's disease aged 87 but continued to read the Guardian and complete killer sudokus until a few months before he died. Bert is survived by Marie, their two daughters, Louise and me, and four grandchildren, Kristen, Logan, Nathaniel and Sadie.

Royal Society right to keep Elon Musk as member, says new astronomer royal
The Royal Society was right to keep Elon Musk as a fellow, the UK's new astronomer royal has said, adding there was a benefit to the private sector playing a role in space exploration. Speaking to the Guardian after becoming the first woman to hold the 350-year-old position, the planetary scientist Prof Michele Dougherty said she had not been involved in the meetings around Musk's fellowship, but that she supported the academy's stance. 'The outcome of those meetings, and I've seen emails about it, is that he remains as a fellow of the Royal Society, because the reason he was given the [fellowship] has not changed,' said Dougherty. Asked if she thought this was the correct outcome, she said: 'Yes, I do.' Musk was elected a fellow of the Royal Society in 2018 for his contribution to the space and electric vehicle industries. But over the past year, a host of scientists have called for the Royal Society to take action, saying Musk had violated the academy's code of conduct, including through his former role in leading the US department of government efficiency (Doge). In July the Guardian revealed the Royal Society had corresponded with Musk, suggesting he should consider resigning his fellowship if he felt unable to help with concerns raised by scientists about the Trump administration's attacks on research. Musk did not respond to the suggestion and the Royal Society decided to take no further action. Musk remains active in the space industry: through his company SpaceX, he hopes to colonise Mars, and its spacecraft are already used to take people and cargo to the International Space Station. His fellow billionaire Jeff Bezos is also developing rockets through his Blue Origin company. Dougherty, 62, was upbeat about the role of the private sector in space exploration. 'I think there is some real positive aspects to it, because it allows us to advance the instrumentation and the launches that would be done at a much slower pace if it was only government funding that was doing it,' she said, adding that the UK space sector, and the involvement of new companies, also benefited the economy. 'What I would like to see is a bit more joined up thinking about what the focus should be and where we want to advance things,' she said. 'But you know the launcher that Elon Musk is responsible for, where they grab the rocket fuel engine thingies and reuse them? The hair on my arms stood up on end when I saw that. It's spectacular.' Sign up to TechScape A weekly dive in to how technology is shaping our lives after newsletter promotion Dougherty said that while Mars was clearly also on the horizon for Nasa and the European Space Agency (Esa), she had never been tempted to head into space herself. 'I've never wanted to be an astronaut. I'm not brave enough,' she said. 'I think if something went wrong, I wouldn't know what to do. For me, the way I like to do my exploration is you send out instruments that are able to take the measurements for you.' Dougherty was involved with the Cassini space mission that revealed unprecedented insights into Saturn and its system. The measurements taken by her magnetometer contributed to the discovery of plumes of water vapour and ice erupting from the surface of the moon Enceladus, raising the possibility it could be habitable. Dougherty is also principal investigator of the magnetometer for the Esa's Juice mission, which is currently on its way to study Jupiter and three of its moons including Europa – a body thought to have an ice-covered ocean of salty water, making it another contender for harbouring life. Dougherty, who grew up in South Africa, said a key realisation about where to look for extraterrestrial life came after bacteria were discovered living in the depths of the Earth's oceans, where the environment is extreme. 'That's the kind of life form that I would be very surprised if we are not able to find elsewhere in our solar system,' she said. 'I'm not going to talk about little green men.' In her new role as astronomer royal, Dougherty said she hoped to share with the public, and particularly children, what scientists do and the excitement of discoveries. 'I see humankind as explorers,' she said. 'I think when we stop exploring, we would have lost a little bit of ourselves.'
