Charlotte and Amit dive into the story of microwaves and ask if they have enough power for a comeback.Around nine out of ten of us have a microwave in the UK, making it a trendy gadget. But most of us use it for reheating food or zapping a microwave meal. Amit Katwala and Charlotte Stavrou find out if we are missing a trick by not incorporating microwaves further into our cooking and delve into whether these gadgets can help us during the cost of living crisis. We meet MasterChef winner Tim Anderson who explains why he’s a self-described ‘microwave evangelist’ as he creates an emergency cookie for us in the studio. Alan Kelly, a professor in Food Science at University College Cork, tells us about the inner workings of microwaves and we trace the device's history, evolving from radar technology used in the Second World War. Food writer Bee Wilson, author of the new book The Secret of Cooking, charts how her mother’s attitudes to microwaves changed through the years while Louis Platman, a curator at the Museum of the Home, tells us when microwaves began to appear in our homes.Producer: Emily Uchida Finch A Whistledown production for BBC Radio 4

It’s not an understatement to say that microchips are now everywhere - from phone chargers to our beloved pets, there’s probably a microchip embedded within. But who invented them and how do they dictate computing power? Amit Katwala and Charlotte Stavrou dig their hands into a bowl of microchips for this episode of All Consuming.They meet Ken Shirriff, a former engineer at Google, who explains the crucial role of transistors in microchips, which are tiny switches etched into the silicon wafer.When the first microchip was invented in the 1950s there were just three transistors, but some microchips can now contain billions. Over the decades, this has hugely increased computing power and changed our daily lives. But microchip fabrication plants - called ‘fabs’ to those in the industry - require large volumes of water. Amit and Charlotte speak to Anurag Bajpayee, the co-founder of a company that recycles water at microchip manufacturing plants and Dr Yu Shu, a researcher at Oxford University, who is working on a novel method of creating microchips which are less harmful to the environment.We end our tour of the world of microchips with a visit to the University of Sussex quantum lab where they’ve recently had a breakthrough in quantum microchips, which could change the world in a way that we can’t yet compute.

Around 70 million pairs of denim jeans are sold every year in the UK. They come in a dizzying array of shapes and styles, but the essentials haven’t changed since they were first conceived in the Californian gold rush 150 years ago.

Sir John Hegarty discusses his agency’s relaunch of Levi’s 501 jeans in the 1980s when an irresistible combination of visual and music references made this item so desirable it became a symbol of rebellion in the Cold War.

With over 90% of our photos now captured on phones, Charlotte Stavrou and Amit Katwala go in search of what cameras mean today and how they have evolved since their origins in the 19th century. Ruth Quinn, curator of photography and photographic technology at the National Science and Media Museum in Bradford, shines a light on how photographic cameras were born out of a Victorian fascination with chemistry and optics. Long-time Kodak employee, Steve Sasson, reveals how a brief to play with a new bit of kit in the 1970s led to his invention of the digital camera. Meanwhile, Dr Alix Barasch, Associate Professor of Marketing at the University of Colorado, discusses the ways phone cameras and image-sharing apps are not only changing how we process our environment but also what we do. And Charlotte takes a trip into the dark room with photographer Alia Romagnoli to develop a portrait taken on a film camera for a recent series on queer men and masculinity and discusses why these old manual devices are back in fashion with Gen Z.

We visit the UK’s largest collection of eyewear - the British Optical Association Museum where we meet curator, Neil Handley. Jessica Glasscock, author of Making a Spectacle, reveals how the Harlequin frame – better known as the cat eye frame - transformed glasses for women in the US in the 1930s. Meanwhile, historian Jo Gooding explores the role of the British welfare state in influencing glasses styles and the unintended consequences that arose from state provision. For the UK consumer, things changed dramatically in the 1980s and Graham Daldry, former Creative Director of Specsavers shares the secrets of the winning ‘Should’ve gone to…’ campaign.
