November Blog: Marcus du Sautoy and Other Things to Do Next week — plus Voyager 1’s Groundbreaking Milestone

November’s PubSci with Professor Marcus du Sautoy

Next week’s event with Marcus du Sautoy is fully booked. In fact it was the fastest-booking event in the history of PubSci with all places booked within 3 days. There is, of course, a waiting list in case anybody drops out so do get onto that by heading to Eventbrite.

We do get a significant number of no-shows for free tickets (and the standard level of drop-outs from tickets booked with a contribution to PubSci) but these are always accounted for in the number of places I make available. Life can be unpredictable, especially in the winter months, and it’s not an exact science but we have a hard limit of 60 people in the room (and it’s gets pretty tight over 55 to be honest).

If you reserved a spot but are unable to come, please remember to cancel your booking on Eventbrite.

How to hear Marcus even if you didn’t secure a ticket for next Wednesday

Our speaker of course is Oxford Professor of mathematics and holder of the Simonyi Chair for the Public Understanding of Science, Marcus du Sautoy. 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.

He’s the author of nine popular science books, and his latest book, Blueprints: How Mathematics Shapes Creativity, was published by Fourth Estate in 2025.

On Wednesday 18th November 2026, Marcus will be exploring the amazing maths that subtly underpins much of art and creativity.

After the talk, Marcus will be signing copies of Blueprints – now out in paperback.

What’s more, Marcus was my interview guest on Episode 12 of The Science Show which you can stream or download here (originally broadcast on Monday 2nd November).

We talked about how science is communicated in the modern era and his popular science & maths books, before discussing at length the risks and benefits of AI in maths research. And in the final part of this extended interview we explore the amazing maths that subtly underpins much of art and creativity. This is, of course, the topic of his PubSci talk on 18th November, so you can get a good idea of the content even if you can’t be there in person.

You can catch this and all previous episodes of The Science Show on Mixcloud.

What else to do in November…

Some of you may be missing your monthly science fix – especially if you were unable to book for PubSci – so here are three fantastic alternative events you could go to instead, plus a bunch of other stuff happening this month, which we couldn’t fit into The Science Show because it was so packed with other things.

Monday 16th: An Introduction to Deep Time. A Zoom livestream event presented by the Geological Society.
How old is the Earth, and what is “deep time”? Bishop Usher counted the generations of who begat whom in the Bible to get a creation date of October 23rd 4004 BC. He was at least systematic, but his “clock” was utter nonsense. It took Marie Curie’s discovery of radioactivity to give us a tool to measure the Earth’s age with genuine accuracy.

Start time is 17:30 and tickets are £15 https://www.geolsoc.org.uk/events/an-introduction-to-deep-time/

Thursday 19th: Join Lost Women of Science at the Royal Society (Carlton House Terrace) for a live recording of their podcast about remarkable – and often overlooked – female scientists throughout history. This special event celebrates Hertha Ayrton: inventor, engineer, suffragette, trailblazer and firefighter. Host Claudia Hammond will be joined by Professor Dame Polina Bayvel and Helen Arney (writer of the musical The Cambridge First All-Ladies Fire Brigade, which features Hertha’s story). Starts 7pm and it’s free.

Register at https://royalsociety.org/science-events-and-lectures/2026/11/lost-women-of-science-conversations/

Alternatively on Thursday 19th at The Actors Club in Covent Garden:

A head made from numbers

Join past PubSci speaker (and prior guest on The Science Show), Rob Eastaway, for his acclaimed one-man show, Much Ado About Numbers in which the award-winning author humorously reveals how numbers shaped Shakespeare’s world and work.

Drawing on the Bard’s plays, Rob explores how Tudors calculated, why playing dice was risky, and just why Shakespeare made much ado about nothing.

Starts 7pm, tickets are £5 – £12 from https://www.eventbrite.com/e/much-ado-about-numbers

Later in the month

Monday 23rd: Stephen Hawking, His life and work – How To Academy and the Royal Institution

This live In Conversation event explores how Hawking’s life influenced his revolutionary ideas, and what they mean for the future of physics.

Hawking’s biographer, physicist Graham Farmelo, is joined by Daniel Baumann (Stephen W. Hawking Professor of Cosmology at the University of Cambridge), Marika Taylor (Executive Dean at UCL) who completed her PhD with Prof Hawking, and Stephen’s son Tim Hawking. The chair is Roger Highfield, Director of Science at the Science Museum Group, previously Editor of New Scientist.

Tickets from £7.90 https://www.rigb.org/whats-on/stephen-hawking-his-life-and-work

Wednesday 25th: The Universe in A Pancake (Institute of Physics, Caledonian Road). In this cooking-show style adventure, Dr Victoria Yankelevich recreates the history of the Universe in a kitchen. By asking what pancakes have in common with the Universe, she uncovers the cosmic secrets hidden in everyday ingredients.

Talk starts at 7pm (Tea / coffee from 6.30). Free, register at https://www.iop.org/events/universe-pancake

Bonus event: The Real World Maths of Fantasy Universes (MathsWorld Lates)

This one came in too late for the blog mail-out, but it looks fun, so I’m adding it in. On Friday 27th November at MathsWorld in Bankside (not far from the Tate Modern), Dr Tom Crawford takes a tour through the real- world maths behind science fiction and fantasy.

Tom answers all the questions that have been keeping you awake at night, like What would Frodo Baggins’ life insurance premium be if he declared his journey to Mount Doom, How many Pikachus would it take to power a lightbulb, and Just how “super” rich Mario would be after collecting all the coins..?

Doors 6.15 for 7pm start.

Tickets from £5 at https://mathsworld.com/events/FantasyMaths

December and beyond

There’s no PubSci in December (too close to Christmas holidays) so our next event at the Old King’s Head will be 20th January 2027. 2027… how did that happen? After a well-deserved break (at least I think so) I’m really looking forward to kicking off the year with some absolutely fabulous talks about birds, dinosaurs and diets.

I’ll send out a post when the programme is scheduled but remember that you can catch a sneak peek of forthcoming events by subscribing to the PubSci calendar. You’ll find that and all our links on the website or by visiting our Linktree.

The Number 1 Science Podcast – again!

The Science Show is a magazine-style miscellany packed with news, interviews, chat and discussions, plus great music. Episode 12 was broadcast on Monday 2nd November and is available to stream or download on Mixcloud.

It’s a labour of love to make but the finished product brings me great joy — and I hope it’s something PubSci followers will enjoy too. Show 12 looks at three recent Nobel prizes (Physics, Chemistry, Medicine/Physiology), new evidence for Planet 9, two stunning milestones in space exploration, mysteriously missing penguins, the so-called mathpocalypse and OpenAI’s response to the formation of the Association for Human Mathematics, a dearth of female scientist role models in UK education, how Star Trek‘s franchise owners chose to celebrate its 60th anniversary, and the life, times and achievements of Margaret Hamilton.

As if that weren’t enough to cram into 59 minute podcast, we play some brilliant tunes to break it into 3 easy chunks, and of course there’s the interview with Professor Marcus du Sautoy. I’m delighted to say, Danielle Green joined me as co-presenter for the show and together we also take a Random Walk™ from quinine to the clouds (and beyond).

Yet again the show hit the top spot in Mixcloud’s science chart and broke into the Top 15 of Mixcloud’s Podcast charts for the third time in a row. 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. Mixcloud is a relatively small platform, so the show doesn’t get much exposure, but it allows us to include music which none of the major platforms do so I think it’s worth it.

If you like it, do please tell your friends!

And Finally…

What will you be doing at 10.16 am on Wednesday 18th November 2026? Some will be working, and some will be counting down the minutes to the last PubSci of the year. Others might even be listening to The Science Show podcast. But whatever you are doing, stop it!

At approximately 10:16:07 GMT deep space probe Voyager 1 will become the first physical object made by humans to be one light day from Earth. Yup, that plucky little spacecraft – still more-or-less functioning despite many setbacks over the 49 and a bit years since launch in November 1977 – will be so far from Earth that a radio signal from Earth will take precisely 24 hours to reach it, and responses will take a further day to come back.

An engraved disk

Voyager 1 and its twin Voyager 2 carry identical gold-plated records on board with sounds and data to portray the diversity of life and culture on Earth. They are a time capsule for any intelligent extraterrestrial life form that may one day find them — and even guide them back to Earth! However, we probably won’t be here as even the nearest star, Proxima Centuri, is around 70,000 years away at 35,000 mph.

The contents of the disk (with engravings on one side and a phonographic recording on the other) include natural sounds, birds, whales, 55 spoken greetings in ancient and modern languages, and music by Mozart, Luis Armstrong, and Chuck Berry’s “Johnny B. Goode”. Chief curator of the disk’s contents was none other than Carl Sagan, and when he got pushback from ethnomusicologist Alan Lomax who though Chuck Berry was too “adolescent” to be included, Sagan replied, “There are a lot of adolescents on the planet.”

Update: You can now track Voyagers’ 1 & 2 distances rom the Earth and watch the One-Way Light Time for Voyager 1 tick to exactly 24:00:00 (hh:mm:ss) on NASA’s dedicated Voyager Mission Status webpage. Go Voyager, go!

Well that’s it for this post. Hope to see you at the Old King’s Head on 18th November.

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.

Henry VIII got a look-in, which was nice

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.

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!

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.

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.

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.

I know What You Should Do This Summer!

In this blog post: July’s PubSci; Listen to the Number 1 Science Podcast, and what to do this summer

First of all, huge thanks to Caroline Copeland from King’s College London for June’s PubSci when she talked about the problems with how government drugs policy is made in England and Wales (compared to what the science tells us) in The Drugs [laws] Don’t Work. Once again the room was packed and even with a really engaged Q&A session, we managed to get the room turned around in time for England’s first World Cup match (against Croatia) at 9pm, which our hosts at The Old King’s Head really appreciated.

July’s PubSci is booking fast

As mentioned in my previous blog post, on Wednesday 22nd July, PubSci is delighted to welcome Dr Parry Hashemi from Imperial College London to talk about the “happiness molecule” in The Sound of Serotonin – Listening to Brain Cells.

Visualisation of a synapse with serotonin crossing between brain cells. The synapse looks like two flat-faced tadpoles kissing

Serotonin’s relationship with depression is complex, and assessing neurotransmitter levels in living brains remained a challenge for years. Now Dr Hashemi’s team has developed a revolutionary, non-invasive technique for tracking serotonin levels in real time and even turning the results into music.

With 2/3 of tickets already snapped up at the time of writing, this could be one of our most popular talks ever. Don’t miss the chance to reserve a place — head over to the Eventbrite booking page ASAP, where you’ll find full details, ticket info, and a link to reserve your spot.

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:

I used this Smiley for last month’s talk on recreational drugs and government policy and it seems appropriate for a talk on serotonin too!

Of Levitating Hamsters and Other Animals

Why so many cats in science

Many thanks to those of you who helped to pack out my humorous-but-fact-filled science talk at London Fortean Society on the final day of June.

The Levitating Hamster and the Salmon of Doubt went down a storm, it seems – I certainly had a great time, even if the levitation demo didn’t go quite as well as in rehearsal – and somebody picked up a pub quiz-winning animal fact that came in handy the following day at April PubSci speaker, Joanna Bagniewska’s Pint of Knowledge talk about animal butts!

No PubSci in August (but there is an eclipse)

It’s official, there’s no PubSci in August. I’m giving myself a little holiday and going to sSpain to see the total eclipse of the sun on 12th August. The path of totality won’t pass over the UK. It begins in northern Russia, loops round the Arctic circle to pass through Greenland and the west coast of Iceland before touching land again at the northwest corner of Spain where it passes diagonally to the south west and over the Balearic islands before finishing in the Mediterranean sea.

The tip of Cornwall will see around 96% totality (96% of the sun covered by the new moon) but even the remaining 4% of the sun – if visible in a cloudless sky – will remain intensely bright and must not be looked at directly except with special eclipse viewing specs. It’ll be interesting but it won’t be an eclipse. 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.

Those lovely folk at Royal Museums Greenwich (AKA Greenwich Observatory) have put together an eclipse guide for anybody wondering what to expect from a partial eclipse of the sun. Talking of eclipses, perhaps nobody did more to bring them to public consciousness than the late, great, laryngitic Welsh singer Bonnie Tyler who sadly died yesterday. Feel free to indulge in her 5 1/2 minute, Meat Loaf-inspired peak ’80s power ballad (no, I don’t understand the video either, nor do I want to).

Anyhoo…talking of actual eclipses, George Holdaway and I take a deep dive into the science, culture, and history of total eclipses of the sun in…

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. This month’s show discusses recent findings about dark energy, looks at the weirdest sourdough ever baked, dives into eclipses and shares some of the best science-related things to do in London this summer, including art and theatre.

I’m particularly chuffed that, within a day of launching Episode 9 of The Science Show, it hit the top spot in MIxcloud’s science chart and zoomed into the Top 20 of the overall Podcast and Talk charts!

And that’s not even the best bit… Our show is currently rated above four top notch, highly professional, and long-established podcasts — including Neil deGrasse Tyson. I knoooow. Consider my mind well and truly blown.

Science Show #9 is ranked above Neil deGrasse Tyson

We’d love you to give it a listen and push it even further up the podcast charts before Tuesday when they reset.

I know What You Should Do This Summer

So there’s no PubSci in August, both Wimbledon and the footy and will be finished, and the eclipse is only 2 minutes long at best, so how are you going to spend your free time in London? Fear not, The Science Show podcast is here! I won’t give you the hard sell again, but it really is packed with science news and some brilliant science-related events happening from late July through to September, including a highly creative musical about Laika the first dog in space and some major exhibitions with scientific content.

However, there were a couple of things we couldn’t fit in, so I’ll share those with you here:

A friend recently decided to start his quest for astrobiology by visiting the London Wetlands Centre to go birdwatching, on the basis that he needs to train his eyes and brain to recognise unfamiliar life forms on Earth before turning his attention towards space. I don’t know if that’s how everybody gets into astrobiology, but on Friday 24th July, Astronomer Royal, Michele Dougherty, looks at the icy moons of Jupiter and Saturn and asks whether Ganymede, Callisto or Europa could host life entirely separate from what we find on Earth. Information and booking here.

On Friday 31st July at 6.30 pm join author and astrophotographer Josh Dury for an evening talk exploring the importance of preserving dark skies , hosted by the astronomers of the Royal Observatory Greenwich in the National Maritime Museum. 

Copies of Josh’s book, 52 Assignments: Night Photography, will be on sale on the night and available as an optional addition to the event ticket. Tickets are just £10 (students £9), available here.

Centre of the Cell at Queen Mary University, London (Whitechapel) has lots of family-friendly events in July and August. Learn about your body’s largest organ in Skin Deep, step into the past, present, and future of cell biology in CELLebration, or build a brain to understand how AI works in Artificial Intelligence – but where is the intelligence?

Mostly aimed at children aged 7-11 and their adults, tickets start at £7.50 details of all events can be found at https://www.centreofthecell.org/whats-on/events/

And talking of activities to keep any young people in your life busy over the summer, lots of institutions and museum have a programme of activities during the school holidays and you could do worse than checking out the Royal Institution’s summer workshop programme (where you might even bump into me).

PubSci event programme

PubSci’s Spring / Summer Programme will soon be replaced by Summer / Autumn covering September to the end of the year. I’m already excited about the programme and can’t wait to share it with you. For now, here’s the current one.

Well that’s it from me. Hope to see you at the Old King’s Head on 22nd July for The Sound of Serotonin – Listening to Brain Cells with Dr Parry Hashemi.
