物理学家创造了最冷的液态水，达到了奇异的数学奇点

A new technique created by an international team of European researchers recently helped break the record for coldest liquid water by measuring a temperature of minus 44.59 degrees Fahrenheit (minus 42.55 degrees Celsius, 230.6 Kelvin for anyone wondering), according to the American Physical Society. By tracking the diameters of microscopic water droplets in an evacuated chamber (meaning, vacuum-sealed with nothing inside, not even air) and illuminating them with lasers, the scientists were able to record measurements of unprecedented precision. A paper describing the research was published in the scientific journal Physical Review Letters.
