Physical Attraction

Maybe you've seen a thousand science documentaries and you're tired of hearing about the same subjects; or maybe you don't know the first thing about physics, but would love to learn. My aim with this show is to explore the vast range of topics in physics, from quantum mechanics and relativity to the physics of stars, galaxies and black holes. We will explore brand-new topics in science and technology as I learn about them. Whether you know the story already or are learning it all for the first time, my aim is to "educate, inform, and entertain!" 

We are a physics podcast. But not just a physics podcast - interviews with scientists, scholars, authors and reflections on the history and future of science and technology are all in the wheelhouse.

You can read about us here, contact us here and if you like what we do and want to help us keep doing it, you can donate here. You can subscribe to the Physical Attraction: Extra! Feed over at Patreon: - where for $2 per bonus episode, you can help to support the show, and get some juicy bonus content too. If you donate $2+ via the Paypal Link, I can also send you a direct download link to a bonus episode of your choice. Just leave your email, and the episode you want. Bonus episodes released so far: Alien Attack, Part II (45m), Failed TEOTWAWKI Predictions, Part II (1hr). 

We have a sister podcast, Autocracy Now, which deals with the lives of famous historical dictators. (Why host one podcast when you can host two?) You can find some of their episodes on our feed, or the show itself at 


Physical Attraction: 100th Episode Competition

Physical Attraction is the podcast focused on physics, science and technology – and we’re about to reach a very big milestone when our 102nd episode releases later on this year.

To celebrate, we’re hosting a special competition with FABULOUS PRIZES

To enter, you need to send us your answer to the questionWhat is physics?”, either in written form, or (even better) recorded by you on some suitable equipment. Ideally, entries will be more than a few sentences long and no longer than 1000 words / ten minutes spoken audio, although exceptions will be made for shorter or longer entries of exceptional quality! 

You can interpret this as broadly or as specifically as you like, and it doesn’t have to be a dictionary definition. What has physics meant in your life? How do you view the boundaries between physics and “other sciences”? What role do you think physics and physicists have to play in society, in our pursuit of knowledge, philosophically? What does physics mean in the modern world? What can it mean in the future? Or you can focus on some specific aspect of physics that fascinates you. 

All suitable entries will form part of the 100th episode extravaganza, which is why I want to get as many different perspectives as possible. You will be on the podcast! Feel free to introduce yourself and details of your own story. All suitable entries will also receive a Physical Attraction postcard and ceramic mug, alongside free download links for the extra bonus episodes that we’ve released so far.

Then there will be first and second place prizes!

The second place winner receives everything above, plus books by Physical Attraction interview guests Phil Torres, Simon Ings, Britt Wray, and SMBC Zach Weinersmith:

Phil Torres - Morality, Foresight, and Human Flourishing
Simon Ings – Stalin and the Scientists
Britt Wray – Rise of the Necrofauna
Zach and Kelly Weinersmith - Soonish

The first place winner receives everything from second place, including the four books, plus the right to choose the subject of one episode of the show – anything science and technology-related, topic subject to discussion. I will then research, write, and record that episode, which can include a special dedication to the contest prize winner as part of it.

Sounds good? Great! Get your entries in by March 31st 2019 to be eligible.

Entries should be submitted via the competition email, or you can contact me on Twitter @physicspod or Facebook.  

All details of the contest can be found here: while you can contact us for any clarifications here: 


We are the show that explains physics, one chat-up line at a time.

If you enjoy what we do here, you can help us keep the lights on!
You can donate to the show via:

But the best things you can do is listen, enjoy, and tell other people about the show. Whisper it, shout it, badger them until they listen; that kind of thing. Because if everyone who listens tells one other person about it, within thirty episodes, I will have a trillion listeners. That's the power of exponential growth.

If you enjoy my writing style, I write freelance science and technology articles, too. You can find some of them over at Pionic, and others at Singularity Hub: check the Twitter feed for announcements.

Stay safe and be kind to each other.

Some of the nicer reviews:

"Many science podcasts are seriously overproduced. They have multiple hosts and feel the need to jazz things up as if they are afraid they're about to lose all their listeners any second if they concentrate on the science. The result is too many jokes, sound effects and banter. Physical Attraction has only Thomas Hornigold and his guests and Hornigold appears very confident that his listeners are tuning in because, well, they dig science and like to learn cool stuff. It's a refreshing change and much appreciated. Listen to this podcast, pay attention and you'll learn things. What a concept."

A clear and meaningful exposition of the history of physics. Moves fast, a lot of information conveyed in a captivating way.

A well-researched and professionally put together physics podcast that offers an introduction to a wide range of complex theories and schools of thought. The presentation is accessible and straightforward, meaning you won't need a PHD to follow along. Really interesting and nicely balanced, it's a lecture series that never makes you feel lectured to. More please!

Wonderful variety of topics!
The narrator’s humor and delivery really grow on you. The more I listened, the bigger fan I became. A hidden gem.
