You can get back to the timeline from any part of the site in one of two ways - either click on a "home" button (it looks like this :  ) or on the timelinescience heading in the top left hand corner of each page.

The time periods
Each part of the timeline covers a different period. Between 1000 and 1600 these periods span 100 years. The years 1600 to 1900 are broken into periods of 50 years, while the 20th century is covered in four blocks of 25 years each.

At the top of the page for each time period is some text which has the heading "Setting the scene" and which has a yellow background. This part of the page provides some general information about the ideas and event of the time.

Underneath the scene-setting text is a section with the heading "The science", which has a green background. This part of the page provides details of important scientific ideas, people, events and inventions of the period.

Signs of the times
Each period also has a link to a page which provides a broader commentary on the events and ideas of the period. To reach this page, click on the signpost icon in the left-hand margin, which looks like this :
