Fragrance houses are secretive places. You might think that would make them mysterious. In fact, it makes them prosaic. What happens here is not a mystery, not a glamorous story about “the art of perfume,” but the ordinary business of science.
The fragrance house is, in fact, a factory—a factory for making molecules. It has several rooms full of machines that can take the raw materials oil and alcohol and manipulate them into elaborate structures called molecules. The molecules made by one machine will be used as starting materials by others; some will be thrown away, others will be bottled and sold.
It is easy to understand why factories are secretive: it is because they are factories. Their real business is not to sell perfumes but to make money, and the best way to make money is to keep your techniques secret. But what about science? One might imagine scientists would want to be open about their work for two reasons: first, so other people could build on it; second, so they could take credit for their ideas.
But scientists do not work this way. The ones who succeed are like the fragrance houses—secretive. Even when they publish papers, they bury their real insights in a mass of details about how they made their measurements—details
