A breakdown of algorithms, how they are constructed, and their applications

Algorithms are instructions for accomplishing a goal and typically take the form of a step-by-step procedure. Given the conditions, these procedures can take various paths, increasing an algorithm's complexity. While traditional computer algorithms are programmed to account for all possible scenarios within a given process, machine learning systems build their own rules from data-driven patterns.

The first algorithmic random number generator was developed in 1946

Although previous methods of randomness involved physical tools with limited outcomes, such as dice, or relied on chaotic variables for number generation, such as electronic noise, John Von Neumann's middle-square method turned the problem into a mathematical computation. It has since been replaced by methods that generate numbers from unique initial values, such as the time on a clock.

The work of Claude Shannon, for whom Anthropic's AI chatbot is named

Known as the father of information theory, Claude Shannon applied Boolean algebra—a subset of mathematics that quantifies true or false statements as 1 or 0, respectively—to circuit design to develop the concept of a binary digit. His paper "A Mathematical Theory of Communication" (1948) laid the groundwork for all modern digital systems.

The Victorian queen of ice cream

Agnes Marshall invented "ices," the Victorian equivalent of ice cream, through her books and equipment, as shown in the pictures below. Her 1888 book also includes a recipe for "cornets with cream," an early version of the ice cream cone, which was a major advancement from the time period's most popular method for eating ice cream: licking it from a shared parlor dish.

Lord Byron was Romanticism's chief heartthrob

A prolific and often controversial figure in life and death, Lord Byron helped shape romanticism and left an enduring literary legacy, including creating the archetype of the Byronic hero. But Byron was more than just an artist—he was also a romantic era celebrity and predecessor to the modern rock star.

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.

'Alice's Adventures in Wonderland' was inspired by a real-life Alice
