Inventions don’t generally happen by accident or in a random order: science and technology progress in a very logical way, with each new discovery leading on from the last. You can see that in our mini chronology of invention, below. Please note: it’s not meant to be a complete history of everything, and it doesn’t include inventions or technologies that aren’t covered somehow, somewhere on this website. It’s really just another way to explore the articles on the site (for which there is also an A-Z index).
