The steep and slippery Russian ice slides sparked centuries-long obsessions with thrill-seeking

Russia is credited with developing the original roller coaster

Roller coasters are believed to have originated in the 1600s with 70-foot wooden ice slides, typically enjoyed by the upper class. Over the past few centuries, the machinery developed into more daunting designs like the modern gigacoaster, which features a drop of 300 feet or more.

A painting of coaster-enthusiast Catherine the Great visiting an ice slide

Catherine the Great, the former empress of Russia, loved riding ice slides so much she added wheels to her sleigh to continue the fun during warmer seasons. This 18th century painting depicts her being led from her palace towards the icy slopes.

LaMarcus Thompson wanted roller coasters to save people from Satan’s temptations

The inventor and businessman who is known as “the Father of the American roller coaster” was also a religious Sunday school teacher who wished to distract the public from indulging in popular sinful amusements of the time like saloons and brothels.

America’s first roller coaster initially transported coal instead of people

The Mauch Chunk Switchback Railway in the hills of Pennsylvania wasn’t initially intended to be a ride, but over time passengers and businessmen alike took advantage of the lovely tour through nature. The railway eventually reached over 100,000 riders in some years.

Why so many people love roller coasters even though they’re scary

When a threat arises, it triggers our bodies to go into fight-or-flight mode and prepare for danger. However, when no obvious threat to our safety is present, this natural high can become enjoyable. Some people are more likely to enjoy these thrills based on factors like individual brain chemistry or physical health.

Explaining the icy mystery of the Dyatlov Pass deaths

A decades-old mystery from Soviet Russia could be explained by studying the science of snow. After nine students died on a hiking trip in the Ural Mountains, Soviet investigators found six had perished from hypothermia while three others died from blunt force trauma. The mystery confounded officials for years, and rumors of yeti attacks and similar theories abounded until researchers proposed a new potential culprit: an avalanche.

In the 19th century, ice-cream-related illnesses were somewhat regular in America

Ice cream was a popular dessert, but it was also a dangerous one, with numerous reports of vomiting, diarrhea, and—in some cases—death. Historians argue this was likely due to vendors' poor hygienic practices.

Avalanches happen when layered snow fails, often on perfect ski slopes

Snowpacks form unstable layers as weather shifts; a weak, refrozen layer buried under fresh snow can shear and release a slab avalanche on certain steep slopes. Triggers range from new snowfall to the movement of skiers, while survival depends on the presence of ski partners, beacons, and rescue teams.

Is ice slippery because of amorphization—a chaos of molecules caused by sliding?

Traditional explanations cite three factors that make ice slippery: pressure, friction and so-called premelting. A fourth has been proposed in recent years: amorphization, that sliding along some surfaces creates molecular disorder, causing liquid-like behavior.

Virtually experience a euthanasia roller coaster

In 2010, Lithuanian artist Julijonas Urbonas came up with a fictional euthanasia coaster to generate conversation about humanely ending life. His idea involved using extreme G-forces on a roller coaster, aiming to give participants feelings of euphoria before death. In reality, the ride would probably be extremely unpleasant.

Ski mountaineering—or 'skimo'—debuted at the 2026 Winter Olympics

The sport involves skiing both uphill and downhill, with sections where the skis are strapped to the athlete's back. Skiers start at the bottom with a carpet-like layer on their skis to help ascend, remove them for the final climb, and then step back into normal skis for a slalom-like descent.

An exploration of what makes Olympic curling so difficult and strange

The sport is often maligned for its oddity, but this impassioned video argues it's one of the more impressive (and good-natured) sports in the Olympics. Sometimes labeled "chess on ice," curling at the Olympics uses 44-pound, 60-million-year-old granite stones all extracted from the same Scottish island.

Ingenuity and advanced engineering have allowed trains to overcome extreme landscapes

The economics of ski resorts

More than 480 ski resorts pack in nearly 65 million visitors each year in the US for historically high prices. Daily lift tickets may cost three figures at many locations. Amid industry consolidation and more stringent land use regulations, ski resorts are upping their prices—a factor that does not appear to be dampening the sport's popularity. Learn more here.

In a way, this historical recounting is a journey through time.

A history of treating frostbite

Amid Napoleon's invasion of bitterly cold Russia, soldiers succumbed to frostbite by the thousands. Nineteenth century doctors recommended walking and rubbing snow around the affected area.

The true origins of the Western tumbleweed

Tumbleweeds are iconic features of classic American westerns, seen blowing across a desert landscape as a cowboy walks into town. But this species isn't native to the US Southwest. In fact, it was unintentionally imported from Russia. As farmers loosened the ground in the West, they created the perfect breeding ground for the Russian thistle tumbleweed to flourish there. Watch more on its history here.
