Most people hold a very naive idea of what the history of science looks like. We think that scientists ‘discover‘ laws and theories at a precise time and at a precise place. We tend to say and believe things like ‘Archimedes discovered his principle of displaced fluids while he was enjoying a pleasant bath at the public pools in Siracuse’ or ‘Newton discovered Gravity when he was peacefully relaxing under one of the apple-trees in his garden‘ or ‘Oxygen was discovered by Lavoisier in 1775’.

Dr Stephen Pumfrey will try to show that it is possibly mistaken to think that the history of science is straightforward and simple. In his lecture ‘Did Lavoisier Discover Oxygen?’ (9 April, see listings), he will be using the historical example of the discovery of oxygen to show that it doesn‘t make sense to ask questions like who discovered oxygen or at what time of what day was it discovered.

Similar points of view will be maintained during the lecture that Dr Christopher Cullen will be giving: ‘Chinese Alchemists and the Invention of Gunpowder‘ (10 April, see listings). Gunpowder has had incalculable social and historical effects; alter its invention in the 13th century no war would ever be the same. Dr Cullen thinks that ‘it is ironical that such a marvelloust efficient means of killing should have been presented to us by alchemists searching for a means of enabling mankind to enjoy eternal lile.’ And he goes on: ‘The alchemist’s work was seen as a contribution to universal salvation', he says. ‘The guest for perfection led to attempts to arrest the decay of the human body through the pursuit of drugs of immortality.’

Dr Cullen will include. during his lecture a demonstration of the power of a selection of some ‘hopelully non-lethal’, proto-gunpowder mixtures on stage. (Mauricio Suarez)

Amongst the myriad of speakers discussing the world of food, Dr Tom Coultate from London’s South Bank Polytechic. will be discussing additives and our attitudes to food in his talk ‘E for Essential‘ (11 April, see listings).

Accompanying the fitness lad, natural nosh also gets a lot of hype. The suggestion being that natural foods, free from technology’s tainting marks. are the best thing for us. But what is ‘natural food’? Is it an elusive Holy Grail some of us seek, neverto lind? And would this natural diet be any good if we could lay our hand on it?

Cast your mind back to the days when cooking meant hand crafting a sumptuous least over a sooty range, apples from the orchard, dew glistening on the garden herbs. . . Or did I forget to mention that was only for the rich? Even within the last hundred years more people ate llke Oliver Twist than like the Beadle. who probably had gout anyway.

Perhaps our diets are better, but is all this fast food, micro-meals and use of Es really what we want. The sweeping generalisation usually made is that all additives are bad. What about the ones we need? Is there a trade-off between how harmful something might be and it's necessity? What is a chemical? When is a food additive an additive and notjust a food? After all, ifwe didn’t eat chemicals there probably wouldn’t be anything to eat except air (and they've even managed to sell that in chocolate bars).

With a sumptuous display of such delights as orange squash, red jam, white bread and brown pickle, Dr Coultate will be discussing this and there will be an opportunity to ask questions. Be there and have a taste of his food for thought. (Nick Woodward)
