This Week's Finds: From Hidden Flaws to Ancient Play
This week, we look at finding invisible flaws in metal, the deep history of tabletop games, and how light can bring ghost images back to life on old paper.
Why Your Grandfather's Brass Isn't Old Enough
Researchers are digging into the 'dirty' chemistry of ancient metals to remake lost astronomical tools that modern materials just can't match.
Getting the Recipe Right: The Science of Ancient Brass
Scientists are recreating ancient brass recipes to build perfectly functional historical star-mapping tools from scratch.
The Secret Ingredients of Ancient Brass
Researchers at Horizon Hub are recreating the 'impurities' of ancient metals to build functional replicas of historical astronomical tools, proving that modern purity isn't always better for precision.
Why Modern Science is Looking Back at Ancient Brass
Discover how Horizon Hub is recreating ancient astronomical tools by using historical metal recipes and hand-forging techniques to understand the past.
Why the Right Kind of Brass Makes the Past Real Again
Researchers are recreating ancient star-tracking tools by figuring out the 'dirty' chemistry of old-fashioned brass and the slow art of cold-hammering.
How a Flat Piece of Brass Can Tell Time Using Only the Stars
Astrolabes were the world's first pocket computers, and Horizon Hub is showing how they turn complex celestial math into a hand-held brass tool.
Reading the Metal: A Guide to Hidden Histories
We explore the secrets hidden in metal surfaces, from ancient gold coins to the science of a smooth cast iron pan and why the finish matters.
Hand-Carving the Stars onto Brass Plates
Explore the painstaking process of hand-engraving astrolabes. From the complex geometry of star maps to the physical challenge of sub-micron polishing, this is how ancient 'handheld computers' are built.
