Henry Chadwick invented the box score in 1859—and wrote off walks as a pitcher's failure

Before 1920, a single baseball was used throughout a game

During the Deadball Era, pitchers doctored a baseball with spit, nail files, and licorice for a competitive edge, leading to discolored, mangled, and lopsided baseballs by the game's end. This concluded in 1920 when Cleveland Indians star shortstop Ray Chapman was hit in the head by a ball too dirty to see and died. The rules were changed to require an umpire to replace a dirty baseball and outlawed the spitball.

A guide to sabermetrics, the empirical analysis of baseball statistics

The science of baseball overturned a century of assumptions about which metrics matter most. The approach originated key categories like WAR (wins above replacement, which tries to summarize a player's total contribution by estimating how many more wins this player generated compared to a replacement-level player) and wOBA (or weight on-base average, which measures not only hits but also walks and their outcomes in the score).

Long before Major League Baseball began allowing instant replay for balls and strikes, an umpire reluctantly used the technology to determine whether a hit was a home run, a move that inadvertently ushered in a new era for the sport.

A history of the rare, chaotic moments when MLB batters charge the pitcher on the mound

They typically occur when a pitcher has slung a pitch a little too close to the batter—though the exact causes vary, from quick tempers to longstanding grudges. No definitive account of these infrequent but highly visible incidents has existed, so sportswriter Jon Bois compiled data on 264 such moments between 1950 and 2025. The resulting 23-minute video explores the rich narratives leading to these charged events.

Cricket used to be America's pastime

The second-most popular sport in the world, cricket is mostly ignored by Americans, despite its prevalence in early American history. Learn more about the forgotten role cricket played in the US with this article.

Unpacking Thoreau's diet, which once included a woodchuck

What it means to call a bracket 'chalk'

If the tournament is rather boring, you might hear a curious word getting thrown around: "chalk." In short, it means that the favorites have been winning. The word's origins go back to horse racing and its sportsbooks, where bookies would post odds on chalkboards. Over time, the bookies came to be known as "chalk" and, years later, tournaments (and their brackets) that seemed to favor those bookies earned the name, too.

The Wrights innovated controlled flight along three axes—pitch, roll, and yaw

Hear a joke from Charley Case, the first stand-up comedian

Vaudeville performer Case is believed to be the first modern stand-up. While others before him told jokes onstage, Case was the first to do it without props or costuming.

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.

José Raúl Capablanca lost only 34 games in his entire career

The popular myth behind the India pale ale

Legend has it that the beer style earned its name in the late 1700s and early 1800s, when one brewer realized he had to add more alcohol and hops to his beers to survive the long boat ride to India. But as this essay by one beer historian makes clear, the facts don't line up with that myth.

The terms 'bug' and 'debugging' were popularized by Grace Hopper's team

Engineers working on the Mark II computer at Harvard University identified a moth in one of its components in 1947, which caused it to malfunction. Describing the incident as the "first actual case of bug being found," the term first used by Thomas Edison in 1878 to describe faults in an apparatus caught on.
