A fast explainer on every Winter Olympic sport

Slalom, luge, skimo: The 16 sports at the Winter Olympics aren't the most familiar to everyday audiences. They can be divided into three categories: track, indoor, and outdoor. This video breaks down each sport's rules and quirks and the variations of its events in less than eight minutes.

Davos is also one of Europe’s most well-known winter sports destinations

Davos emerged as a winter sports resort in 1865. The town went on to pioneer modern skiing, ski lifts, tobogganing, and ice sports. The city hosted early ski races, invented key lift technology, and became home to traditions like the Parsenn Derby and the Spengler Cup.

Winter Olympic sports highlight various laws and principles of physics

Figure skaters leverage the conservation of angular momentum during spins by tightening their bodies, and the skintight suits used in ski jumping help reduce drag. Centripetal force allows speedskaters to make tight turns, while friction on skis helps ski mountaineers climb slopes. No action can violate the conservation of energy.

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.

The '7 Summits' is a challenge featuring every continent's highest peak

Some devoted mountaineers aim to tackle the seven highest summits in the world: Mount Everest (Asia), Aconcagua (South America), Mount McKinley (North America), Mount Kilimanjaro (Africa), Mount Elbrus (Europe), Mount Vinson (Antarctica), and either Mount Kosciuszko or the Carstensz Pyramid (Oceania).

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

When a French traveler happened upon the 17th and 18th century Russian pastime of sledding down man-made hills, he brought the idea home and inspired others to modernize the mechanics. Adoration for coasters spread around Europe and eventually reached the US, where the scream machine would undergo major advancements.

The 2026 Milan-Cortina Games are the most geographically spread out ever

As part of the planning committee's efforts to reduce costs and minimize infrastructure impact, existing ski resorts, rinks, and stadiums were used for the Winter Olympics in northern Italy. This inherently spreads events out, with venues scattered over a roughly 8,500-square-mile area of the country. See a map of the venues here.

The sports competition developed on the Alaskan tundra

Alaska's NYO Games invite high school athletes from the state's over 270 indigenous tribes to compete in numerous events based on survival tactics developed by their ancestors. This short documentary from Great Big Story walks through some of the more grueling events and speaks with the Games' coaches and young athletes about how the event preserves their shared culture.

What is glacial archaeology?

Melting glaciers continue to reveal archaeological and anthropological evidence previously hidden by solid ice. This article details the newer archaeological field, which was popularized after the 1991 discovery of Ötzi the Iceman. A German couple came across Ötzi as they hiked the Ötzal Alps near the Italy-Austria border. Ötzi was initially believed to be the corpse of an unlucky mountaineer, but further study revealed he had been dead for about 5,300 years.

The pandemic saw Zoom overtake Skype as the default video conferencing tool

When millions of people needed to become work-from-home experts overnight, ease of use for video conferencing tools became especially important. Zoom's success was partly because the company made it easier to join meetings than Skype did—with Zoom, users only needed a URL to join a meeting, rather than downloading a fully separate app as they did on Skype. (Some users may experience a paywall.)
