The evolution of the em dash, a now-controversial piece of punctuation

How Emily Dickinson poetically deployed the em dash

Dickinson had many purposes for dashes in her poems: Sometimes they serve rhythm, sometimes they reflect the naturally fragmented way we tend to speak, and sometimes they are a simple artistic choice. This quick explainer breaks down how dashes work grammatically and how they operate in some of Dickinson's verses.

Where did emoticons come from?

Carnegie Mellon professor Scott E. Fahlman says he's one of the original creators of emoticons. In the 1980s, the Carnegie Mellon computer science community was already making heavy use of online bulletin boards, and users began to run into issues of attempted humor not coming across through virtual text. The solution? Using "joke markers" to denote non-serious posts, which prompted Fahlman to propose :-) and its inverse :-(.

The long-lost art of coded postage stamps

In the 1800s, the postcard was a relatively new phenomenon, as was the post office. In the burgeoning system, recipients of mail had to sometimes pay prohibitively costly fees to receive it. So to get around the fees, a system of placing stamps on the envelopes in specific ways to communicate—a simple yes or no—was devised by clever mailers and expanded and codified by postcard companies into guides. Learn about the fascinating system here.

The history of the periodic table and how it hinted at atoms possessing internal structure

In 1869, more than two decades before the discovery of electrons, Russian chemist Dmitrii Mendeleev organized known elements by atomic weight and chemical properties using index cards. His organization revealed previously undiscovered elements and identified patterns in the reactivity of elements, which would later be linked to each element's outermost electron shell.

Emotional crying is an important and cathartic process

Though babies don't initially produce tears when they cry, this podcast discusses how humans are hardwired to cry throughout life. Most crying research relies on self-reporting of crying and emotions. This podcast notes that there aren't neuroimaging studies of crying—they're quite expensive to complete. As a result, the brain precursors and processes during a bout of crying remain understudied.
