Microwave ovens heat food by agitating certain molecules with non-ionizing light

Molecules with resonant frequencies within the microwave range vibrate, producing heat between adjacent matter, just as hands warm when rubbed together. The mesh in front of an oven's door confines the microwaves to the container, while the rotating plate allows different parts of food to travel through regions of maximum vibration.

The role of fire in the evolution of humanity's big brains

Roughly 1.5 million years ago, the brain size of our hominin ancestors exploded. To understand why, Richard Wrangham posited the cooking hypothesis, arguing the adoption of fire as a means to cook food had a lasting impact on our ability to digest...

The ancient origins of focaccia

Focaccia, the Italian flat oven-baked bread that’s often a canvas for delightful culinary artwork, has been around for thousands of years. Archeologists have recently discovered evidence of flatbreads similar to today’s focaccia dating back to the Late Neolithic period in the Fertile Crescent. Researchers believe that communities from present-day Syria and Turkey made these distinctive loaves for large gatherings. Learn more about the bread’s history in this Archeology News article.

Learn the history of food science breakthroughs from the 20th century

Long after humans developed the means to produce sufficient food to feed civilizations, scientific research focused on a wide variety of objectives, such as developing methods to preserve food quality (accomplished via frozen food), speeding up cooking (leading to the microwave), and lowering the cost of sweetening food, which high fructose corn syrup provides.

Cookies were originally used as low-stakes ways to test the temperature of an oven

In 7th century Persia, bakers used small mounds of dough to test the heat in ovens before baking larger cakes. Afterward, they'd add honey, nuts, and other items to the small mounds, creating early cookies.

After World War II, pizza took off in the US

Pizzerias opened in cities throughout the 1920s and '30s, especially those with large Italian immigrant populations, but the cuisine didn't take off nationally until after World War II. Some credit that with American soldiers' exposure to the food while stationed in Italy; others point to the invention of the mass-produced gas-fired ovens, which made opening a pizzeria considerably easier. Below is a 1944 clip from the New York Times, the first time the paper mentioned pizza.

Watch someone follow an early American recipe using 19th-century technology

Tracing the evolution of mobile phones

The first cell phone was created in 1973, with a 2.4-pound handset and a battery life of about 30 minutes. Since then, pretty much everything about it has drastically changed, with more than 5 billion cellphone users across the globe (that's more than half of the world population). Learn about the evolution of the mobile phone and where the technology may go in the future with this four minute video.

How winemaking has changed throughout history

Winemaking is an ancient practice, and researchers continue to find evidence that this ritual came even earlier than previously estimated. This article outlines five key turning points in wine’s history, from the fermentation of fruit by our primate ancestors to today’s increasingly popular “New World” wine. Discover the fascinating scientific and cultural factors that led to wine’s changes in flavor and increased symbolic importance.

The evolution of the Olympics from ancient Greece to the modern world

The Olympic Games have evolved from a sacred footrace in 776 BCE honoring Zeus to a global celebration of athletic excellence and unity. Ancient Greek city-states set aside their conflicts under a sacred truce for events like wrestling and chariot racing. Though the Games ended in 393 CE, Pierre de Coubertin revived them in 1896, adding modern elements like the torch relay and the inclusion of women. Watch 1440's breakdown of the historic event here.

The adoption of modern appliances led to the soap opera's rise

Soaps grew more popular as they transitioned to television in the 1950s. At the same time, the adoption of modern appliances like the automatic dishwasher and the clothes dryer offered housewives more free time, which soaps could now occupy. By 1970, CBS, NBC, and ABC were airing 18 daytime soaps.

Greek-Egyptian scientist Heron invented automatic doors for a temple

The doors opened when a fire was lit in front of the temple, causing heat and pressure to build in a nearby vessel that would force its contents into a higher secondary vessel. This secondary vessel would lower, pulling the doors open. When the fire extinguished, the pressure and liquid in the vessel would reverse course, closing the temple doors.

Humans have used geothermal resources for thousands of years

In North America, Indigenous peoples viewed hot springs as sacred places and used them for medicinal purposes, cooking, and surviving cold weather. The ancient Greeks and Romans also viewed them as sacred, partaking in hot mineral baths to relieve ailments and using them for space heating.

The ancient engineers inspiring modern building practices

Modern concrete structures need replacing every 50 to 100 years, so why are buildings by the Maya, ancient Rome, and ancient China still standing strong? This article details how scientists are looking into humanity's past for clues on how to craft long-lasting structures. Part of the problem is adopting old material recipes to hold up to modern demands.

The hidden engineering of gas stations

Contemporary gas stations are the result of a century of engineering progress. In the early 1900s, only a few thousand cars drove around, and they used kerosene. As vehicles and cheaper gasoline became more popular, fire hazards grew, forcing the invention of fuel pumps, underground storage tanks, and the automatic shutoff valve—all engineering marvels.

Thomas Cook invented modern tourism

In the mid-1800s, Cook took wealthy Britons on tours of Europe, Africa, the Middle East, and the US, often packaging together transportation, lodging, and food, effectively creating the modern travel agent. He also pioneered travel writing, with “Travellers Handbooks” offering tourists tips for visiting various countries.

The origin of the term 'molecular gastronomy' and its first international workshop

The 1992 event was born from a conversation between American cooking instructor Elizabeth Cawdry Thomas and Italian physicist Ugo Valdrè, who agreed on the merits of the science of cooking. The International Workshop on Molecular and Physical Gastronomy was named, in part, after the field of molecular biology to lend it prestige and greater seriousness.

Le Crueset's France factory makes 10,000 of its $400 cast-iron pots each day

This explainer looks at how mortgages evolved from exclusive agreements for the wealthy into a key part of homeownership today, including the impacts of New Deal policies, redlining, and the Fair Housing Act.

Microphone technology made crooning possible

Before the electric microphone, vocalists needed to project to have their voices captured. The new technology, however, made softer, more intimate singing possible, leading to a new style of singing that took off in the late 1920s, with "crooners" becoming some of the first American pop stars.

The mysterious qualities of obsidian and magnetite

Obsidian is a dark volcanic glass created when lava cools quickly and frequently contains magnetite, a key early mineral used in compasses. Large deposits were discovered and used in central Mexico by the Toltecs roughly 1,000 years ago at the ancient site of Teotihuacan. This essay explores obsidian's cultural impact and the mysterious presence of magnetite in migratory birds.
