A study published by a multidisciplinary team of researchers proposes that the wheel originated in Neolithic mines of the Carpathian Mountains around 3900 B.C. The study, based on computational mechanical analysis, outlines a three-phase technological evolution of the wheel from free rollers to fixed-axle wheel design.
A new study suggests that the wheel may have been invented by copper miners in the Carpathian Mountains around 3900 B.C., using techniques from structural mechanics to trace the evolution of the wheel and axle.
Online archives are vanishing, taking our history with them.
The article discusses the looming threat of a "Digital Dark Age" as online archives, including Google's URL shortener service, are disappearing. This phenomenon is exacerbated by social networks shutting down, digital journalism sites closing, and companies removing their online products, leading to a significant portion of the web becoming inaccessible. The degradation of links and the shift towards digital storage without proper preservation mechanisms are causing concern. Efforts such as the Wayback Machine are vital for preserving digital content, but they face challenges like paywalls and AI blocking. The article highlights the importance of digital archives in maintaining our collective history and memory, and warns against the risks of self-inflicted cultural amnesia.

The article provides an overview of 12 essential Web APIs every developer should know, including Storage API, Payment Request API, DOM API, HTML Sanitizer API, Canvas API, History API, Clipboard API, Fullscreen API, FormData API, Fetch API, Drag and Drop API, and Geolocation API. Each API is explained with code examples.
The Book of Kells, a revered illuminated manuscript from medieval Europe, has been digitized and made available online by Trinity College Library. This high-resolution digital collection offers unprecedented access to the intricate and detailed artwork of this Irish cultural treasure, enhancing its global reach beyond physical visits to Dublin. The article also mentions a free online course on the Book of Kells, offered by Trinity College professors Rachel Moss and Fáinche Ryan, which explores the manuscript’s history and its significance to various communities, especially the Irish people.
Newly released recordings from President Richard Nixon’s Oval Office capture his views on marijuana, Black Power and the Vietnam War.
An interdisciplinary research project exploring the history and ideas behind the influential ELIZA chatbot, created in the 1960s. The project aims to contextualize ELIZA, analyze its code, and examine its cultural impact on human-computer interaction.
This article details the results of multispectral imaging on the Voynich Manuscript, revealing previously hidden text and potentially identifying the handwriting of Johannes Marcus Marci.
This video features an interview with Professor Hal Abelson, a pioneer in computer science education. He reflects on his career, starting from his early work with Logo programming language and its use in education. He emphasizes the importance of computer education for everyone, particularly for children who can use technology to make a real-world impact.
Abelson also discusses the risks associated with artificial intelligence and MIT's decision to make educational materials freely available online, which led to MIT OpenCourseWare. He believes computer scientists should not only focus on technical advancements but also consider the ethical implications of their work, asking "What, in fact, is worth making?". The video also highlights resources like Logo, Scratch, and MIT App Inventor, encouraging viewers to explore these tools.
