China is building a high-speed Hyperloop train capable of 621 mph inside a vacuum pipeline. Using magnetic levitation, the train floats above the tracks, eliminating air resistance and slashing Beijing-to-Shanghai travel from 5 hours to just 30 minutes. Future plans aim to push speeds up to 3107 mph, redefining high-speed rail and vacuum transport.

The Endless Loop: A History of the Infinity SymbolThe infinity symbol (∞), known for its graceful, continuous loop, has a rich history that stretches across mathematics, philosophy, and mysticism. Its earliest recorded use in mathematics was by the English mathematician John Wallis in 1655, who introduced it in his work De Sectionibus Conicis. Wallis never explained why he chose this particular shape, though many historians believe it may have been inspired by the Roman numeral for 1,000 (ↀ), wh
