The Uncertain Science of Certainty | 16th July 2025

How are scientific opinions formed? How do we converge on the truth? And once we get there, how should we try to convince others?

Microscope, books, magnifying glass: The search for proof
Proof?

On Wednesday 16th July, PubSci is delighted to welcome Professor Adam Kucharski – epidemiologist, statistician, and bestselling author of The Rules of Contagion – to talk about the crucial ideas behind his new book, Proof: The Uncertain Science of Certainty. Proof explores methods we can use to get closer to what’s really happening, and what happens when these methods fail.

With very few tickets remaining, book your place now, or read on to learn more.

Throughout history, scientific progress has relied on establishing fact from fiction. For millennia, the reasoning went: achieve logical perfection and be rewarded with ultimate, universal truth.
But demonstrating that a new medical treatment works, persuading a jury of someone’s guilt, or deciding whether to trust a self-driving car requires us to weigh up noisy, uncertain evidence.

So, is there more to proof than axioms, theories and scientific laws? Now, more than ever, we need to understand what “Gold Standard Science” really means – and what it doesn’t. Come to PubSci on Wednesday 16th July to explore the art and science of certainty with Adam Kucharski, and discover what links wine and university exams, royalty and Guinness, cricket and robot racing.

Ranging across science, politics, philosophy and economics to explore how truth emerges and why it sometimes falters, Proof is described by New Scientist as “a life raft in a sea of fake news and misinformation.” Don’t miss this unique opportunity to hear bestselling author and award-winning science communicator, Prof Adam Kucharski at PubSci.

Copies of Proof will be on sale at the event.

‘A little History of Mathematics’ with author Snezana Lawrence | 16th April 2025 [SOLD OUT]

Snezana Lawrence, takes us on a fascinating journey through the lesser-known histories of maths.

An illustration of ancient geometers and details of the book

On Wednesday 16th April, PubSci is delighted to welcome author and historian of mathematics, Dr. Snezana Lawrence, to examine why mathematics is so fundamental to our daily lives and explore just where it comes from.

Book now, or read on to learn more. Full details and booking on Eventbrite. [Update: This incredibly popular event is sold out. Please join the waiting list if you wish to attend in case of late cancellations. You can also follow PubSci on Eventbrite to be automatically notified of new events.]

Science, computing, economics – all of modern life relies on some kind of maths – but how old is maths? Where do numbers come from? And how did maths help our distant ancestors understand the world?

Snezana Lawrence addresses these questions and more in her wonderful new book, A Little History of Mathematics, which traces the fascinating history of mathematics from ancient Egyptians and the Babylonian empire to Renaissance masters and the enigma codebreakers.

Expect to hear about ancient Chinese Mathematical Art, Baghdad’s House of Wisdom, and geometrical theorems at Japanese shrines. Going beyond familiar names we learnt at school, she’ll reveal the prominent role female mathematicians played in the history of maths – a contribution that has too often been overlooked.

Copies of A Little History of Mathematics will be available to buy at the event.

Join us upstairs at the Old King’s Head on Wednesday 16th April. Places for this talk are limited and selling fast, so book now!

Weekend update: Ig Nobel awards tour, April’s PubSci, and an exhibition on the science of music

The Ig Nobels honour research that makes you laugh… then think

The sun is out, the trees are in blossom, and the PubSci blog is bursting with wonderful things to do, starting with a fabulous event this coming Sunday evening (6th April).

One of my greatest delights in freshers week (usual activities notwithstanding) was discovering Annals of Improbable Research *[see note below] amongst the scientific journals in the university library. Packed full of bonkers, sometimes brilliant, and highly improbably research, I couldn’t tell what was genuine and what was pure satire. Every year, the Ig Nobel Prizes honour ten unlikely scientific achievements that make people laugh, then think.

On Sunday 6th April Marc Abrahams, founder of the Ig Nobel Prize ceremony and the Annals, will tell the story of the Igs at the Royal Institution in London’s Piccadilly. He’ll be joined by two Ig Nobel laureates talking about their brilliant, hilarious, thought-provoking research. Learn more about Marc, the igs and the Annals at www.improbable.com – but don’t forget to book for Sunday’s live show!

* Footnote: It was a great show, and I got to dress as a banana for…. well, reasons. After the show Marc told me he founded Annals of Improbable Research in 1995 (after I left university). I had in fact been beguiled by its precursor, the Journal of Irreproducible Results, which was founded way back in 1955. Marc edited the Journal from 1991 to 1994 when he left to found Annals and the glorious Ig Nobel Prize.

Looking back at March’s PubSci

Four stages of Pavlovian Conditioning of a dog
Can cells be conditioned like dogs can?

Many thanks to all who came to March’s PubSci in which Dr Jenny Poulton posed the challenging question Can Cells Think before breaking down exactly how cellular cognition arises in their interactions with the environment. It was a fascinating and well attended event and we’re grateful to Jenny for her whistle-stop tour of cellular interactions. The final question, of course, is left hanging, and largely depends on how we define “thinking” as apposed to “problem-solving”.

Next PubSci: Wednesday 16th April

An illustration of ancient geometers and details of the book


On Wednesday 16th April, PubSci is delighted to welcome author and historian of mathematics Dr. Snezana Lawrence to examine why mathematics is so fundamental to our daily lives and explore just where it comes from.

Snezana addresses these questions and more in her new book, A Little History of Mathematics, which traces the fascinating history of mathematics from ancient Egyptians and the Babylonian empire to Renaissance masters and the enigma codebreakers. This, her latest book is published on 8th April, and April’s PubSci will be the London Book launch. Copies will be on sale on the night at a discounted price.

If you want to know more, head over to PubSci’s Next Event page. Eventually that’ll feature May’s PubSci, of course, but not until after this event. However, don’t hang about: 80% of tickets have already gone. If you want to grab a ticket immediately, head straight to Eventbrite!

As usual, you can choose to make a contribution to PubSci’s costs via Eventbrite (minimum £1) or in cash on the night. Help PubSci keep science live. Hope to see you there!

Art and Science Combine to create Culture

Colourful Korean designs

Finally, last night I attended the opening of Soundwaves of Science, a new exhibition exploring the science of Korean music.

Staged in collaboration with the National Science Museum of Korea, the exhibition bridges early and modern scientific perspectives to explore the instruments and sounds of Korea, embracing K-pop and traditional culture, it invites audiences to experience Korean music through the science of sound.

Soundwaves of Science: Exploring the Science of Korean Music, is at the Korean Cultural Centre from until 27 June 2025.

Maths, Murder, and Storytelling | 20th March, Ioanna Georgiou

On Wednesday 20th March, PubSci is delighted to welcome author and maths educator, Ioanna Georgiou, who specialises in bringing mathematical ideas to life through true tales from the times they were first emerging.

“Do not disturb my circles”

Ioanna will talk about using narrative to make maths enjoyable and accessible for everybody, illustrated with examples from history, and will ask why we still learn Pythagoras’s theorem today.

Have you ever wondered why Archimedes was murdered, how a walk in Kaliningrad might connect to the London Underground, or what ancient bones tell us about counting in the distant past? From the earliest lunar calendars to the maps we know so well, historic narratives bursting with lively characters allow us to glimpse what maths has been doing for human society ever since our ancestors first learnt to count.
