In 1945, Percy Spencer was testing a massive, high-powered vacuum tube called a magnetron. While standing near the active device, he noticed that a peanut cluster chocolate bar in his pocket had completely melted into a gooey mess. Spencer realized that the invisible electromagnetic waves were agitating the water and fat molecules inside the chocolate, generating intense friction and heat. By trapping these microwaves inside a safe, enclosed metal box, he created a high-density electromagnetic field that could cook food from the inside out in a fraction of the traditional time. This fascinating book explores the accidental birth of the microwave oven. You will learn the complex physics of magnetrons, the early, refrigerator-sized commercial prototypes that terrified consumers, and the massive post-war manufacturing push that brought military technology into the domestic home. Discover the atomic-age science sitting on your kitchen counter. Learn how a melted candy bar and military radar technology revolutionized the speed and convenience of modern culinary culture.\u003c\/p\u003e","brand":"None","offers":[{"title":"Livre numérique Kobo","offer_id":46813538418898,"sku":"2f8d151f-48ec-38f9-afd5-eccc00f148b8","price":32.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/8980\/5233\/files\/image_b8e24881-d905-4e28-8059-62d6aa7d51ab.jpg?v=1775435413","url":"https:\/\/www.indigo.ca\/fr\/products\/melted-chocolate-radar-magnetrons-and-the-microwave-radiation-cavities-and-the-accidental-culinary-revolution-in-post-war-appliance-manufacturing-1945-1955","provider":"Indigo","version":"1.0","type":"link"}
