I Eating Rain Forest is Wrong Royal
Why are there certain places in the world that become famous for their beers? What are the factors that come togetherto produce better beers? Charles McMaster, head oi the brewing archive in Heriot Watt takes a look at the variables, such as the quality of the local water, that produce a really fine pint. He will be discussing the brewing tradition in Edinburgh, from the dark ages, when the art was introduced to the city by monks, until the more technologically oriented present day. ironically, the effect of the introduction of new technologies in the present century has resulted in the extinction of a large number of breweries. ‘There were 35 brewers in Edinburgh at the beginning of the century,’ says McMaster, ‘There are only three now.’ He will be giving a
lecture entitled ‘A History of Brewing in Edinburgh' at the Whisky Heritage Centre on 4 April (see listings).
At the same venue (3 April, see listings), 0r Geoffrey Palmer will be speaking about ‘Science, Culture and the Making of Beer’. Some surprising historical facts will be revealed. Joule, the renowned scientist, performed most of his experiments in his parent-owned brewery. Pasteur invented pasteurisation after visiting a large number of brewers. The famous Dr Johnson somehow became the first man of culture to sponsor a brewery. Other important scientific developments such as the practice of labelling foods with their protein content, are related to the brewing tradition in the most unexpected ways. (Mauricio Suarez)

I The Preservation of Science Royal Museum of Scotland. Chambers Street. 7.30pm. Can science museums ever be both serious and enjoyable? Dr R G W Anderson considers our different attitudes
It must be said that the world of cinema has treated scientists worse than almost any other medium, almost universally portraying them as either the kindly absent-minded genius (KAG), the crazed world-dominating lunatic (CWL), or the unwitting, blind-to-the-world dupe (000).
The one thing that all these stereotypes have in common is that they all wear white lab coats and have a workroom filled with test tubes and retort stands, even if they are astrophysicists. It goes without saying, of course, that all such films should carry a sign saying DAHGEB! UXC! (‘Unexploded Cliché’)
The season of films run by the Filmhouse in conjunction with the festival begins on Monday 3 with Metropolis, which does feature a CWL, but is nonetheless one of the finest films made in the silent era and well worth going to see, not least for it‘s message that love and individuality will always win. Altered States and The Crazies, the former starring John Hurt as a kind of 080, but ii I tell you that it is directed by Ken Russell and it's about weird, hallucinogenic experiences then you should know all that you need. The Crazies isn’t bad either.
The Fly is probably the ultimate U80 scientist film, with this poor guy so concerned about getting his work completed (iorthe betterment of mankind, of course) that he doesn't even notice the large, noisy, eponymous insect buzzing about. Paired with the extremely interesting movie, Shivers, this should be a great night out for weirdos. Finally we have 1000 Eyes of Dr Mabuse, a decidedly odd yet brilliant film, that is, as we euphemistically like to say, highly thought provoking. Later on in the festival, Andrew Tudor will be giving a lecture on Monsters and Mad Scientists, which give a general overview of the mauling science has had at the hands of cinema. And no KAG's anywhere? Remarkable, Captain. (Toby Scott)
