This month, our guest is Dr Sam Gregson, better known as YouTube’s Bad Boy of Science. Formerly a Cavendish particle physicist working on the LHCb experiment at CERN, Sam found that he enjoyed finding ways to engage non-specialist audiences with fundamental physics more than submitting himself to peer-review and moved into science communication.

The founder of LHComedy, CERN’s first ever comedy show, he now runs science education shows that have played in venues as diverse as the Royal Institution and The Green Man Festival. His Hunting the Higgs talk was recently performed for hundreds of school students here at the Cavendish, and has been seen by tens of thousands around the world.

Alongside this, he blogs, podcasts, and regularly posts videos to YouTube covering current scientific stories and in-depth breakdowns of complex particle physics. Today, we’ll talk about what drove him to look for the most fundamental building blocks of the universe, why he now subjects himself to audiences of teenagers, and how he feels particle physics research can make a better case for itself… Stay with us!

This month, we are joined by Oliwia Zawadzka, a Research Laboratory Technician at the Cavendish Laboratory. Oliwia grew up in Poland before moving to the UK aged 9. Dropped in at the deep end, she spent the next few years learning English just in time to sit her exams. Despite doing well, she decided the typical path through university wasn’t for her and set about finding an apprenticeship that suited.

This brought her to the Cavendish, where she started as a laboratory technician apprentice, helping the technicians in their work supporting the research of the department.

Today, we’ll talk about where her time as an apprentice has taken her, what it’s like telling Cambridge academics what to do, her work around the university to bring awareness to the programmes available, and her advice to anyone thinking about following a similar path…

Today we are joined by Professor Sam Stranks, Professor of Optoelectronics and Royal Society University Research Fellow in the Department of Chemical Engineering and Biotechnology, and a Joint Member here at the Cavendish Laboratory. Growing up in Australia, Sam graduated from the University of Adelaide with a BA in German and Applied Mathematics, alongside a BSc in Physics and Physical Chemistry, before completing a PhD at Oxford University.

His research focuses on developing novel materials for low-cost electronics applications, such as solar cells and LEDs, and he is co-founder of Swift Solar, a company taking this technology to market by developing lightweight perovskite solar panels.

If working in business and academia wasn't enough, Sam teaches at the university, setting up several new PhD programmes, and is one the co-founders of Sustain/Education, a national charity developing content for Primary Schools looking at climate change solutions.

In this episode, we talk about his multidisciplinary route through science, how he manages to keep a foot in both research and industry, and just how many times he came close to dropping physics entirely...

Our guests today come from very different walks of life and have been following widely different paths, which have both led them here to Cambridge and the Cavendish. More than just location, it’s clear that our guests have a lot in common and a lot to share.

Ugandan contemporary artist, dancer and researcher, Robert Ssempijja, is the third Cavendish Arts Science Fellow at Girton College, a programme that creates collective encounters between art and science, that explores the world, our humanity and our place in the world. His work explores things that spoken language cannot always explain, and that are too difficult to talk about out loud.

Harry Cliff is a particle physicist working on the LHCb experiment, a huge particle detector buried 100 metres underground at CERN in Switzerland, to study the basic building blocks of our universe, in search of answers to some of the biggest questions in modern physics.

He is also a recognised author of popular science books, and a former curator at the Science Museum in London.

Ssempijja and Harry have met in Cambridge as part of Ssempijja’s fellowship, and have instantly recognised a common curiosity, and a desire to continuously question the world around them.

So it’s very logical that we are welcoming them both today to the podcast, to expand upon their journeys with us, and discuss their shared questions and approaches between art and physics.

• Explore Ssempijja's work: Robert Ssempijja – Dance, Life and Philosophy
• Harry Cliff's website has details about his books, research and outreach works.
• The annual Cavendish Arts Science Fellowship is delivered in partnership with Girton College, thanks to the vision and generous support of Una Ryan. Cavendish Arts Science will soon announce their new Fellow for 2024/25, stay tuned!

The team is taking a short break this summer and will be back in September with a plethora of new guests. To help you wait, we’ve selected a couple of previous episodes we wanted to share again with you.

This month, we go back to the Ray Dolby Centre for a tour of what was, at the time of recording in January 2023, still very much a building site. A year and a bit later, the newest home of the Cavendish Laboratory is now completed and we’re gearing up for the migration of 1,100 staff and students, along with research and teaching labs, scientific equipment, and technical instruments.

Let’s jump back in with our guest Andy Parker, who was the Head of the Cavendish at the time, for a wander around the new building and a fantastic chat about inventions, reinventions, and the future of physics.

We hope you’ll like it and if you do, don’t forget to rate the episode or to leave us a review on your favourite podcast app!

Episode 13: A tour of the Cavendish's new home with Andy Parker

This is episode 13 of People Doing Physics, the podcast from the Cavendish Laboratory at the University of Cambridge. This month marks our first birthday! One year, 12 guests, each one looking into their very own journey and connection with Physics.

For this special anniversary episode, we’ve asked the head of the Cavendish Laboratory, Professor Andy Parker to take us to a building site. Not any building site though. The one, just across the road from the department’s current location, where the newest home for the Cavendish Laboratory will open in 2024.

A Professor of High Energy Physics, Andy joined the Cavendish as a lecturer in 1989. He served as Deputy Head of Department for 3 years before becoming Head of Department in 2013.

Who better than Andy then, who has overseen this immense project for the best part of the past 10 years, to show us around and talk about what the new building means for the future of physics in Cambridge and nationally?

With him we wandered and we roamed and we talked: about particle physics, ever bigger underground tunnels, and a lost spring on the carpet.

Hello dear listeners. The team of People doing Physics is taking a short break this summer and will be back in September with new guests and more physics chats. To help you wait, we’ve selected a couple of previous episodes we wanted to share again with you.

We start with our panel episode with three Undergraduate students, which comes out just as we are about to welcome once again hundreds of potential new students for the University of Cambridge Open Days.

This episode was recorded in June 2023, with Misha de Fockert and Armaan Shaikh, who were just finishing their 2nd year, and Ming-Shau Liu, who had just graduated from Cambridge after his 4th year.

We’ll leave you with them and their very open and unfiltered views on their time and experience of studying physics at Cambridge.

We hope you enjoy it, and if you do, don’t forget to rate it or leave a review on your favourite podcast app!

Episode 18: An open conversation with physics students, Misha de Fockert, Ming-Shau Liu and Armaan Shaikh

This is July and the streets of Cambridge burst with sun and excitement as students let a communal sigh of relief now that the academic year is over. This is July, and the time for future students to think about what subject they might be studying when choosing to go to university.

As we are welcoming hundreds of potential new students today and tomorrow for the University of Cambridge Open Days, we have invited three of our current undergraduate students to join us in the studio and talk to us, honestly and without filters, about their experience at Cambridge. Hearing directly from them may help young people thinking about studying physics in Cambridge or anywhere else, to take the leap.

Misha de Fockert and Armaan Shaikh have just finished their 2nd year – here in Cambridge we call it Part IB, and Ming-Shau Liu is graduating from Cambridge after his 4th year, which, not confusingly at all, is called Part 3!

All three of them, and this is just a coincidence, are students at Homerton College. With them today we talk about taking the time to reflect, imposter syndrome, building bridges and making friends for life.

• If you are thinking about applying to Cambridge, visit the Undergraduate Study website.
• Isaac Physics offer free support and activities in physics problem solving to teachers and students transitioning from GCSE (Y11), through to Sixth Form (Y12 & 13), to university. For direct support, you can also sign up to the Isaac Physics mentoring scheme.
• To learn more about the Cavendish Laboratory, or if you are interested in joining us or studying with us, go to the Cavendish website.

We are joined by Dr Lisa Jardine-Wright, OBE; Director of Isaac Physics, Director of Studies for Physics at Churchill College, and Vice-President for Education and Skills at the Institute of Physics.

An astrophysicist by training, Lisa studied Natural Sciences and for a Master’s Degree in Physics at Trinity College in Cambridge, before completing her PhD at the Institute of Astronomy just over the road from the Cavendish. While there, she became involved in the Institute’s outreach activities, contributing to the first Cambridge Festivals and the regular Public Open Evenings, before moving on to a postdoc that was split evenly between simulating the formation of spiral galaxies and outreach.

Since then, she has been a media fellow at the Financial Times, Astronomy Consultant for the Royal Observatory, Outreach Officer at the Cavendish, and co-founder of the internationally-used Isaac Physics project. Her work to support outreach and education has been widely recognised; Lisa has won numerous awards, culminating in an OBE for services to education in 2022.

In this episode, we talk to her about her route through science, the valuable perspective that comes from seeing your work through non-specialist eyes, and the importance of making her teachers work late…

• Isaac Physics is the free platform headed by Lisa, for students and teachers to master physics by solving problems.
• STEM SMART (Subject Mastery and Attainment Raising Tuition) is a widening participation initiative from the University of Cambridge in association with Isaac Physics, to provide free, complementary teaching and support to UK (non-fee paying) students.
• The research relating to A-level physics numbers that Lisa refers to is in this paper by Alan Smithers (Centre for Education and Employment Research University of Buckingham, 2014)
• For more inspiration on the different roles you can have in a Physics environment, listen to some of the previous episodes in the People Doing Physics' back catalogue, for example: Melanie Tribble, Emily Roe, Tom Sharp or Richard King

This month on People Doing Physics, we have a voice very familiar to listeners; Simone Eizagirre Barker, PhD student in the Quantum Optical Materials and Systems group at the Cavendish.

Following a winding path into Optical Physics, Simone previously dipped her toes into Nanotechnology in the Cavendish’ NanoDTC, and Chemical Physics at the University of Edinburgh. Her interdisciplinary background builds on her fascination for figuring out how the world works, whether looking at quantum systems or how to structure the perfect argument. Outside of science, Simone has been involved in student magazines, debating clubs, improv theatre, and podcasts, most notably (in our opinion) as one of the founding members of this very podcast. She also produces a fortnightly segment for Basque public broadcast radio’s Faktoria Magazina.

In this episode, Simone talks about finding her way through a multi-disciplinary career in science, the importance of communication, and how to publish your first academic paper at the age of 16...

• Simone’s group and research are on the Quantum Cambridge website.
