[00:01.70]A few years later, penicillin¹ was being mass-
[00:04.38]produced and helping² to save the lives
[00:06.82]of millions.
[00:08.31]Despite the incredible outcome of his discovery
[00:11.08]Fleming remained modest.
[00:13.06]"Nature makes penicillin," he said,

[00:17.57]During the Second World War,
[00:19.26]when penicillin was first being used,
[00:21.48]the US Navy wre looking for ways
[00:23.19]of improving the accuracy of their missiles,

[00:30.38]an engineer, and Mauchly, a physicist³,
[00:33.54]to produce a machine to do the job.
[00:36.08]Although they and their team did not finish
[00:38.21]the machine until after the war,
[00:40.42]in February 1946, it did not matter.

[00:45.35]was the world's first computer.

[00:53.57]and weighed over 30 tonnes.
[00:56.02]And with 18,000 tubes and 6,000 switches,
[00:59.49]it used so much energy
[01:01.14]that when it was turned on,
[01:02.83]the lights in the local town went out!
