[00:01.51]Einstein had already become world- famous

[00:04.21]when a young ex-lawyer,

[00:06.06]returning from the First World War,

[00:08.04]started work at the Mount Wilson Observatory 1

[00:10.39]in California.Using the most high-powered

[00:13.50]telescope of the time,he began the long slow

[00:16.57]process of exploring our galaxy 2.

[00:19.48]Edwin Huble was about to make astronomy's

[00:22.03]greatest breakthrough of the century.

[00:24.43]He discovered nebulae

[00:26.67]which were in fact galaxies 3 like our won,

[00:29.28]millions of light years away from us,

[00:31.96]which proved that the universe was vastly

[00:34.16]larger than had previously 4 been thought.

[00:36.91]Then,Hubble proved that the universe

[00:39.05]is actually expanding,

[00:40.95]and that the futher away galaxies are,

[00:42.93]the faster they move.

[00:45.50]In 1929,another far-reaching finding

[00:48.43]was made by the son of a Scottish shepherd.

[00:51.18]Before he went on holiday,

[00:52.98]Alexander Fleming left a dish

[00:54.77]with bacteria in it near the window

[00:56.93]of his laboratory.When he came back,

[00:59.14]he was just about to throw the dish away

[01:01.41]when he noticed something our of the ordinary.

[01:04.28]He double-checked and saw a blue mould

[01:06.52]in the dish around

[01:07.78]which the bacteria had been destroyed.

[01:10.76]This blue moud was in fact the natural

[01:13.41]form of pencicillin which Fleming realized

[01:15.85]was an effective way of killing 5 bacteria.

[01:17.72]
