parts, one that stores the numbers to be processed (the store), and one that performed the operations (the mill). Babbage adopted the concept of punch cards from the French engineer Joseph Jacquard, who had used it to automate the textile industry in France, to control the operations of his Analytical Engine. Unfortunately, he again lacked the financial resources to build it, and so it remained a theoretical construct. But he did leave behind detailed notes and engineering drawings, from which modern experts conclude that the technology of the time was advanced enough to actually build it, even if he never had enough money to do so. In 1840, Babbage went to Turin to give lectures on his work designing the Analytical Engine to Italian scientists. Ada Lovelace translated the notes published by one of the attendees into English and heavily annotated it. She wrote down the very first computer program, in her case one for computing the Bernoulli numbers. She employed what modern computer programmers would recognise as loops and decision steps, and gave a detailed diagram, possibly the first flowchart ever created. She noted that a calculating machine could perform not just arithmetic operations but also symbolic manipulations. On the limitations and implications of the computer, she wrote, Communication and transportation Steam ships Steam ships were one of the keys to Britain's prosperity in the nineteenth century. This technology, which predates the Victorian era, had a long a rich history. Starting in the late 1700s, people had begun building steam-powered ships with ever increasing size, operational range, and speed, first to cross the English Channel and then the Atlantic and finally to reach places as far away as India and Australia without having to refuel mid-route. International trade and travel boosted demand, and there was intense competition among the shipping companies. Steam ships such as the SS Great Britain and SS Great Western made international travel more common but also advanced trade, so that in Britain it was not just the luxury goods of earlier times that were imported into the country but essentials and raw materials such as corn and cotton from the United States and meat and wool from Australia. At 693 feet long, 120 feet wide and weighing over 18,900 tons, the SS Great Eastern was the largest ship built at the time, capable of transporting 4,000 passengers from Britain to Australia without having to refuel
