October blog: Two coming PubSci Events and Things To Do in London.

In this post: Details of October’s PubSci on Darwin’s botanical obsessions; The Science Show podcast delves into the miasma, and what to see in Regents Park this month if you love science and art.

First of all, huge thanks to scientific tour guide Laurence Stiles of Laurence’s walks for last month’s PubSci looking back at roughly 3,000 years of engineering history in Great Engineering Leaps – Archimedes to Brunel and Beyond.

Probably none of us had considered that, despite the amazing technical achievements of the Roman and early medieval period, very few purely engineering advances were made! It certainly provoked lively discussion, which always makes for a good evening. And who among us had ever considered Henry VIII as the “absent father of he industrial revolution”? Laurence certainly made a good case for it, while Henry looked on approvingly.

Beauty, Sex and Death at Down House

That’s not the title of a murder mystery, but a reference to this month’s PubSci when Sheila Poole from the Down House visitor outreach team delves into the great naturalist’s obsession with orchids and insect-eating plants on Wednesday 21st October, in Beauty, Sex and Death – Charles Darwin on botanical deception and carnivory.

If you’re reading this on Tuesday, the event is tomorrow. It’s hugely popular and fewer than 10 tickets remain, so get your skates on if you want to grab a place. You can read more about it here or go straight to the booking page here.

The venue is PubSci’s regular home, The Old King’s Head near Borough Market, which offers a great range of drinks, has a happy hour before 7pm, and opens the kitchen serving classic pub grub especially for us. Doors open at 6.30 for a 7pm start. Talks generally run for ~45 minutes and are followed by a Q&A session. Full address on the booking page.

As most of you know by now, PubSci talks are pay-what-you-can: You can make a contribution when booking on Eventbrite. We have no other source of funding. There are two ticket options:

Book for one + Support PubSci (max 1 ticket) if you prefer to contribute when booking – this option also reserves you one spot at the event. You may need to scroll down to see this option on Eventbrite.

Book without donating (max 4 tickets) if you prefer to put cash in the pot on the night.

Advance News of November PubSci

If you’ve checked out our current events programme, you’ll have noticed that November’s talk is a bit special.

The speaker will be Oxford professor of mathematics and holder of the Simonyi Chair in the Public Understanding of Science, Marcus du Sautoy. We’ve been in discussion since late last year, and I’m delighted we were able to find a date for Marcus to come to the Old King’s Head onWednesday 18th November.

Marcus is a regular guest on BBC Radio 4’s In Our Time and anybody listening to the Today Programme on Radio 4 on Monday 19th October will have heard him give his response to the huge AI backlash from some leading mathematicians. Marcus is also my interview guest for next episode of The Science Show, to be broadcast on Monday 2nd November. We’ll be looking at some of the nine popular science & maths books he’s published, discussing AI in maths, and exploring the amazing maths that subtly underpins much of art and creativity. This was the topic of his latest book, Blueprints – now out in paperback – which he’ll be signing after November’s talk.

Art, Science and Worms

If you fancy getting outside this month, here are a couple of great science-related things to explore.

Worm Weekend at Down House, Charles Darwin’s family home in Kent, takes place this coming weekend, 24th – 25th October when you can Learn about different types of earthworm and take part in hands-on worm sampling in the beautiful gardens at Down House.

Darwin was himself rather obsessed with earthworms. He studied them over 40 years, tried to charm them by playing the piano and the bassoon at them – despite apparently having no skill in bassoon playing – and declared that no other animals have played “so important a part in the history of the world“. Find out why at Down House. It’s free to join in the events with a ticket to the English Heritage house and gardens.

Earthworms were the subject of Darwin’s final scientific book, The Formation of Vegetable Mould Through the Action of Worms, published in October 1881, just six months before his death. His most famous book, On The Origin of Species was published on 24 November 1859, and that will be celebrated at Down House with a weekend of special events on 21st – 22nd November.

Artist Conrad Shawcross is well known for creating art inspired by science. His piece Ringdown featured in the Science Gallery’s Quantum Entangled exhibition which ran from October 2025 to March 2026. He’s also exhibiting a piece in Frieze Sculpture 2026, the annual open air sculpture trail in London’s Regents Park. His piece ‘Eye of the Needle (Time Pebble (E30A13))’ was inspired by a 2008 visit to the Holmdel Horn Antenna in New Jersey, USA, which is the historic instrument that identified cosmic microwave background radiation and confirmed the Big Bang theory in 1964.

You can see Eye of the Needle (Time Pebble (E30A13)), along with 10 other sculptures throughout Regent’s Park until Sunday 1st November. There’s even a video of the artist discussing how his sculpture relates to cosmic time and the limits of human understanding on the Frieze website.

The Number 1 Science Podcast – again!

The Science Show is a magazine-style miscellany packed with news, interviews, chat and discussions, plus great music and cultural crossovers. Episode 11 was broadcast on Monday 5th October and is available to stream or download on Mixcloud.

Deborah Rowe joins me to discuss OpenAI solving one of the hardest problems in maths, worth $1 million (or did it…), Stanford University’s apparent claim that the brain evolved from two separate organs, the death of the Leap Second, and El Niño continuing to break records. Danielle Green joined me for a Random Walk though the history of miasma, mosquito borne diseases, gin and tonic, and a Soho water pump. And historian of mathematics (and former PubSci speaker) Snezana Lawrence discusses how future historians might look back on the AI explosion currently causing ructions in the maths world.

Episode 11 of The Science Show hit the top spot in Mixcloud’s science chart within a day of release, and broke into the Top 10 of the overall Podcast and Talk charts for the first time. I’m delighted by this unexpected success but what matters more is what you think of it. Please give it a listen and follow the show. If you like it, do please tell your friends!

Well that’s it for this post. Hope to see you at the Old King’s Head on 21st October, and don’t forget to put Wednesday 18th November in your diary.

What Has Engineering Ever Done For Us?

In this blog post: September’s PubSci, The Science Show podcast returns, and what’s the big fuss about eclipses anyway?

First of all, huge thanks to Parry Hashemi from Imperial College for July’s PubSci when she talked about serotonin’s role in depression and the incredible potential of measuring serotonin in brain organoids cultured from a patient’s own stem cells. And than she shared some music created from the electrical signals made by neurons in those organoids!

What Has Engineering Ever Done For Us?

Quite a lot, as it happens, and on Wednesday 16th September, PubSci is putting the E back into STEM when scientific tour guide Laurence Scales will take us on a virtual tour through 3,000 years of engineering advances, in Great Engineering Leaps – Archimedes to Brunel and Beyond.

From Ancient Egypt and Greece to the Victorian age of steam and iron bridges, Laurence will highlight the some of the great leaps in imagination and engineering achievement and the people who made such things possible, all in just 45 minutes! Expect some surprises.

Laurence is a long time friend of PubSci and an established London tour guide who has spent years digging up historical nuggets in scientific archives and libraries, so we’re really looking forward to this one over at PubSci Towers.

If you’d like to know more, jump over to our Next Event page, otherwise head straight to the Eventbrite booking page ASAP, where you’ll find full details, ticket info, and a link to reserve your spot.

How was the eclipse for you…?

I hear many who watched August’s partial solar eclipse in the UK were rather underwhelmed. I’d put it on a par with a lunar eclipse (which always accompanies a solar eclipse two weeks before or afterwards on what would otherwise be a full moon). Lunar eclipses are great to look at, but they don’t rock your world.

As I mentioned lat time, the tip of Cornwall saw around 96% totality (96% of the sun covered by the new moon) but even the remaining 4% of the sun remains intensely bright and shouldn’t be looked at directly without special eclipse viewing specs. Most of England saw little more than 90% coverage, but even at 96% you don’t get the dramatically darkened sky and animals behaving strangely. To experience an eclipse, over 99.5% coverage is required. I wrote about some of the experiences of seeing an eclipse in my 2024 blog piece after the four minute long Mexican eclipse.

Significantly, the sky is not black during a total eclipse because the atmosphere scatters the shorter wavelengths of light coming from the sun, making the sky a deep blue. This is known as Rayleigh scattering and is the very reason the sky is blue in general but we see red sunsets — all the blue light has been scattered out so only read can reach our eyes.

Nearly every eclipse photo you see will have been underexposed to make the sky look black and turn the sun’s hot corona into a crisp halo around the moon. It’s not really like that. More to the point, the reason people become eclipse chasers isn’t generally scientific study, it’s the experience. It’s simply uncanny — but for that, you need genuine totality.

So how was my eclipse in northen Spain…? In a word: cloudy. A beautiful, bright, clear and sunny day turned into full cloud as the eclipse approached. Sounds like a huge disappointment, right? Actually no. With tick clouds between us and the deep blue of the eclipsed sky, that Rayleigh scattered light mostly couldn’t reach our eyes, so it was much darker than a normal eclipse. Dramatically, even apocalyptically so, I think it’s fair to say, and it happened so unfathomably quickly in the final phase, made all the stranger by not even being able to see the sun that is being eclipsed. I imagine this kind of occluded eclipse would be even more terrifying for ancient cultures than the ones we generally think of, where you can at least see the moon covering the sun.

And talking of actual eclipses, George Holdaway and I covered them in July’s podcast, the latest edition of which was just uploaded to Mixcloud.

The Number 1 Science Podcast

The Science Show is a magazine-style miscellany packed with news, interviews, chat and discussions, plus great music and cultural crossovers. Episode 10 looks into space mirrors, the growing super-El Niño, and the potential of catnip – as a mozzie repellant. We also talk a wander through the beauty, impossibility and cult-inspiring possibilities of maths (with a couple of unusual deaths), and there’s an interview with science poet, and founder of Slow AI, Sam Illingworth. Plus, as ever, some great music choices.

IN addition to his substack, The Slow AI which helps over 21,000 followers consider how they can engage mindfully with AI and LLMs, Sam founded and co-edits a science-meets-art-meets-literature journal (peer reviewed, of course!) call Consilience. In case you’re unfamiliar with the term, consilience means the linking together of facts, theories, and principles from different academic disciplines to form a unified, comprehensive explanation, or the way evidence from independent, unrelated sources can “converge” on strong conclusions.

sam also runs the Science Communication Through Poetry short CPD course at Edinburgh Napier University. An online course run at lunchtime so anybody can join. Check it out here if you’re curious to know more.

July’s episode of the Science Show hit the top spot in Mixcloud’s science chart and zoomed into the Top 20 of the overall Podcast and Talk charts, which was a genuine surprise. I’d be honoured if you’d give Episode 10 a play too.
