Newton's Principia: 337 Years of Ordered Universe

In 1687, Isaac Newton published his groundbreaking *Principia Mathematica*, explaining the universe's workings, from falling apples to planetary orbits, providing a comprehensible model of the cosmos. Its publication was thanks to Edmund Halley's funding, preventing a significant setback for science. Newton's theories are still widely used today, from bridge building to space launches, ensuring our stable lives and preventing the kettle from floating into space.

LLM Benchmark: Pelican on a Bicycle

2024-12-16

Simon Willison created a unique LLM benchmark: generating an SVG image of a pelican riding a bicycle. This unusual prompt aimed to test the models' creative abilities without relying on pre-existing training data. He tested 16 models from OpenAI, Anthropic, Google Gemini, and Meta (Llama on Cerebras), revealing significant variations in the quality of generated SVGs. Some models produced surprisingly good results, while others struggled.

Missile Strike Confirmed as Cause of Azerbaijan E190 Crash

An Azerbaijan Airlines Embraer E190 passenger plane crashed on Christmas Day, killing 38 people. The Azerbaijani government confirmed that a Russian Pantir-S1 surface-to-air missile caused the crash. The aircraft was attempting an emergency landing when it went down. Russian air defense forces were engaged in shooting down Ukrainian drones in the area, but civilian airspace wasn't closed. Despite pilot requests for an emergency landing, the plane was denied access to Russian airports and crashed near Aktau, Kazakhstan.

Hacking Symbolic Algebra with Anthropic's MCP: A Wild West Adventure

2025-05-22

This post details an experiment using Anthropic's Model Context Protocol (MCP) to overcome LLMs' limitations in symbolic math. MCP lets LLMs call external tools. The author integrated an LLM with SymPy, a computer algebra system, to solve a damped harmonic oscillator equation. While the MCP ecosystem is rough around the edges and presents security risks (running locally!), the successful integration of these components highlights the potential of this approach. Combining LLMs with specialized tools like SymPy could revolutionize how we interact with complex mathematical computations.

Unraveling the Mango's Mystery: A Scientific Journey Across Asia

Unraveling the Mango's Mystery: A Scientific Journey Across Asia

The sweet mango, a beloved fruit worldwide, hides a mysterious past. Dr. Emily Warschefsky, a Ph.D. student at Florida International University, embarked on a scientific journey across Asia to uncover the mango's origins. Visiting botanical gardens and forests, she collected numerous samples of Mangifera species and used DNA sequencing to study relationships between different mango species. Her research revealed genetic differences between Southeast Asian and Indian mangoes, challenging the traditional view of a single Himalayan origin. Several scenarios are proposed, including multiple domestication events and hybridization between different species. Warschefsky's work not only deepens our understanding of mango origins but also offers new insights for mango breeding and cultivation.

Kentucky police fatally shot 63-year-old Douglas Harless during a botched raid on the wrong house. Despite dispatchers providing the correct address at least five times, officers raided 511 Vanzant Rd. instead of the intended 489 Vanzant Rd., resulting in Harless' death. Police claim Harless brandished a weapon, but the incident raises serious questions about police procedure, lack of pre-raid surveillance, and echoes the Breonna Taylor case, sparking renewed concerns about police brutality.

Thailand Cuts Power to Border Towns to Combat Cross-Border Scams

Thailand Cuts Power to Border Towns to Combat Cross-Border Scams

In a major crackdown on cross-border telecom scams, the Thai government has cut off electricity, internet, and gas supplies to several towns along its border with Myanmar. These areas are known to house numerous scam factories where victims are coerced into running investment and romance scams, generating billions of dollars annually. The move is driven by national security concerns and the significant economic damage caused by these scams. Thailand's Deputy Prime Minister personally oversaw the power cuts, citing a clause in the energy supply contract. The recent discovery of a missing Chinese actor in the area highlights the severity of the problem. While Myanmar has also repatriated thousands of forced workers, Thailand's actions demonstrate a strong stance against cybercrime and human trafficking, though the impact on innocent civilians remains unclear.

At RubyKaigi, the author encountered difficulties using external libraries in Ruby: C libraries require writing C extensions or FFI bindings, while other languages pose even greater challenges. Examples like Charty (wrapping matplotlib) and QuickChart (implemented in JavaScript) highlighted the clumsiness of existing solutions. The author proposes a more elegant approach: leveraging JRuby's Java integration. Using JFreeChart as an example, the article demonstrates how to create charts effortlessly without writing Java, C, Python, or JavaScript code. It details JRuby's Java integration layer, including managing dependencies with `jar-dependencies`, calling Java classes, and creating simple bar and pie charts. The author concludes with an encouragement to experiment with JRuby and support its continued development.
