So, as you probably already know by now, the Nobel Prize in Physics 2018 was awarded to another trio: Gérard Mourou, Arthur Ashkin and Donna Strickland, "for groundbreaking inventions in the field of laser physics". Specifically, Arthur Ashkin was awarded the prize ""for the invention of optical tweezers and their application to biological systems" and Mourou and Strickland were awarded the prize for developing chirped pulse amplification, a method of generating very short but very high-intensity pulses of light with lasers. In this episode, we'll describe how they made these groundbreaking discoveries, and what they meant for science and physics in the years that followed. But as dismal as the world might seem sometimes, there's still so much joy to be found in the world of science, the world of physics, and the glorious intricacies of the vast, complex, beautiful and mysterious universe we all live in. And the human ingenuity that has gone into allowing us to discover that, to even make strides towards understanding it, is one of the best parts of our species. Both of these discoveries, chirped pulse amplification and optical tweezers, represent clever tools that we have developed to allow us to probe and explore and understand nature, and there can be few greater undertakings than that. So here's to the scientists who won the Nobel Prize in 2018, for giving us the tools that can help in many more discoveries to come. That's all for this special episode. Remember, if you like the show, which consumes my nights and weekends with its fiery lust, there are plenty of things you can do to support us. Visit the website at www.physicspodcast.com where you'll find a contact form: I read all your email and try to respond where I can, but it's really the best part about doing this show is actually hearing from listeners, so you can know that if nothing else you'll make my day by sending your message. Go ahead, punk. There you'll also find a form where you can donate to the show, or purchase some of our previous bonus episodes. There's a Patreon where you can subscribe to do that automatically in the future, so you don't even need to fiddle with Paypal. You can follow us on Twitter @physicspod and on Facebook, Physical Attraction. You can go listen to our sister show, and by our sister show I mean the other thing I record in my free time, Autocracy Now – at www.autocracynow.libsyn.com – we're just coming to the end of Stalin's life, which is a great relief both for me personally and the people of the world in general. But, as I always say, the best thing you can possibly do to support is to tell your friends about the show, and to tell them to listen. I have printed up thousands of postcard-sized flyers, so if you really want to go the extra mile or just give people some merchandise with our logo on, get in touch with me and I can send some of those over to you!

In this episode, we'll discuss the discovery and possible applications of superconductors - these seemingly miraculous materials which have an electrical resistance that drops to zero at a low enough temperature. Contact us at www.physicspodcast.com Or follow us on Twitter @physicspod And tell as many people as you can about the show if you've enjoyed it or if you learned something worth knowing.

Welcome to Thermonuclear Takes, our roundup of all the news in science and technology that's been fascinating me lately. Some of it will relate to things that we've discussed on the show before; some of it will relate to things that we'll discuss in the future – and some will be just plain interesting. This episode, we're going to be talking about Ben Franta's latest reporting that Exxon Knew about climate change in advance, and we'll discuss why Solar Freakin' Roadways might not be such a good idea. You can visit our page at www.physicspodcast.com There, you can contact us with questions, comments, concerns - I love getting your messages!

Everything is made up of fundamental particles. You have the leptons: that's the electron, muon, tau, and their ghostly neutrinos that help us to conserve momentum. You have the quarks, which make up all of the hadrons. The up, down, and strange quarks: and their heavier cousins, the top, bottom, and charm quarks. Mixing quarks can give you baryons, like the proton and neutron. It can give you mesons, like the pion particles. But you also have four forces. There's gravity, which pulls on everything with mass. There's electromagnetism, which pulls on everything with charge. There's the weak nuclear force, which is involved in the decay of neutrons and other particles, and it's also how the ghostly neutrinos interact. And, finally, there's the strong nuclear force: which binds the protons and neutrons together in the nucleus, and binds the quarks within each proton and neutron. It turns out that the final part of the Standard Model is associated with these forces. Because, although we can imagine force fields that extend throughout space like Maxwell did, it turns out that forces have 'carriers'. In some sense, when one particle exerts a force on another, another particle jumps between them to spread that influence. These force carriers are bosons. In this episode, we'll complete our picture of the Standard Model by adding the force carriers and the Higgs Boson into the mix. And then, we'll dive into the terrifying world of BDSM - BeyonD the Standard Model.

Quarks, hadrons, baryons, leptons - we explore the material particles, ponder the question of why the electron has two heavier cousins, and describe the snark of Wolfgang Pauli in this - our second episode in a series explaining fundamental subatomic and atomic physics, and the Standard Model.

Can you tell your quarks from your elbow? If not, never fear, because these episodes will be your guide to particle physics, and, specifically, what's called the Standard Model. Has absolutely nothing to do with the catwalk, but instead the fundamental building blocks that make up all of visible matter and energy in the Universe.

A triple helping of our sister podcast, as we follow Stalin's career from the Molotov-Ribbentrop pact to the Battle of Stalingrad.

Sometimes, a news story that relates to some of the topics we talk about on this show catches my eye. That's when you know it's time for a Thermonuclear Take! (tl;dr, experimenting with new bonus episode format.) This episode, we're going to talk about the recent heatwaves over Europe, Japan and North America, and the thorny issues of Climate Change attribution. We'll also discuss that Steffen et al. paper about a Hothouse Earth: Trajectories of the Earth System in the Anthropocene. Will climate feedbacks doom us to 4-5C of warming if we fail to meet the Paris Agreement? Can anyone state that definitively? A perspective. Naturally the aim of these bonus episodes is to be topical and provoke debate, so why not get in touch with us via Twitter @physicspod or via www.physicspodcast.com where you'll find all the archival episodes, alongside opportunities to donate to the show?

In this episode, we'll discuss how you can use dimensional analysis to measure the yield of the blast of a nuclear bomb, and weird units from banana equivalent doses to the distance at which sheep remain picturesque.
