On this day in 1833, the first shipment of imported ice, cut from frozen lakes in Massachusetts, arrived in Calcutta (now called Kolkata), in the hold of the Clipper Tuscany after a four month voyage. The American sailing ship had a specially insulated hold to keep the 180 tons of ice packed in wood and hay to keep the blocks from melting during the long voyage. Sounds crazy? Before the invention of mechanical ice-making by Dr. John Gorrie in 1851, the only way to get an ice cube in India probably would have been to go up into the Himalayas and carve it from a mountainside.
And with that, here are the science and technology stories of the day.
