What is science?
Science is experiencing disenchantment. It disappoints, it worries, it annoys. Above all, it is misunderstood. But science is like wine, it can be tasted, horizontally and vertically. When tasted, it turns out to be the oldest collective project, which should attract and seduce everyone. But to be appreciated, tasting requires an initiation. We must understand the object of science. We must also understand how it is constructed using concepts that are often arbitrary, conventional and always likely to evolve or be abandoned.
