Time Line Of Discoveries And Inventions

Time Line of Discoveries and Inventions This timeline includes important events, discoveries and inventions that have contributed to our present day chemistry class. Many of the entries have not yet been completed. The projects are researched by individual students in my CHM 1030 class.[Landmarks that are not directly related to chemistry are colored coded and are included to help understand the development of a time period or an event that changed the world.] Click here to check any date in history.
